[ivory agate]

I see, I couldn't find anything to get it to work though

[scenic echo]

You should look at documentation, i remember it was something with transform, just search for "transform" and you will find it

[regal bear]

tm.players.GetPlayerTransform(playerId)

[uncut glade]

does anybody know how to make these buildings?

[cinder spruce]

@junior widget improved formation mod

[junior widget]

am i not able to just download it on the workshop itself?

[cinder spruce]

the workshop upload is from jess, he'd have to update it
or he'd have to let me upload this version

you can just put the mod from this in the mod directory

[cinder spruce]

https://steamcommunity.com/sharedfiles/filedetails/?id=3585918112
i guess here's an unlisted upload
instead of the eyeball it uses the 1x1x1 tube

place the block as close to the center of mass as possible
also here's a BP of the block with the decal being the front:

[regal bear]

A new update for Track Creator Plus is now on the Workshop. This includes the new StringAlong tool plus a few minor tweaks. Details in the Topic here: #1404642052129423466

[radiant lion]

Feel free to upload it

Same is valid for any future time

[cinder spruce]

oops i did a dumb
max force value doesnt do crap, its stuck at 75

ima fix up some stuff then upload it, with thumbnail as well

[cinder spruce]

alright here it is

very poorly made drawing of the settings

[junior widget]

how did i not see any of this, this is very understandable though.

[ivory agate]

Wait can you do transparency already by exploiting AA?

It just depends on what AA the game uses

[topaz arrow]

should i do a modstructure.destroy() or .despose()? i assume .destroy() but am not 100% sure

what is the difference between the two?

[radiant lion]

Iirc one is instant, one does the deletion animation

[topaz arrow]

thats an... interesting difference

i assume there still isnt a good way to detect collision vs being despawned?

[radiant lion]

Don't think so

[topaz arrow]

🙁

[warm canopy]

Dispose I’ve always found more reliable

[topaz arrow]

Is the modding api somewhere online? Like the lua file with comments and whatnot. Was wondering whether i gotta download it for my phone or i can find it somewhere

And is there a way for a raycast to not collide with a specific structure, but to collide with everything else?

[cinder spruce]

terrorsoul has his modding portal with a section of all the functions listed out

https://mods.trailmakers.ludixi.com/docs

[topaz arrow]

Actually, in what ways can a block disappear? Collision, getting its health mowed down with a gun or sth, what else?

[topaz arrow]

That looks... incredibly useful. Thanks!

[cinder spruce]

backspacing or respawning

[topaz arrow]

Does repairing also count? Like for detached blocks and whatnot?

[junior widget]

@cinder spruce the mod wont switch through the modes i select, its always just the line formation instead of transforming into the others.

[cinder spruce]

alr gimme a sec

[cinder spruce]

seems to be working fine?
do you have a video?

[junior widget]

might be because im only using three aircraft

[cinder spruce]

the V and diamond are identical while using 3 or less aircraft

[junior widget]

yea when i switch to any other formation it always stays as the line formation

[cinder spruce]

are you able to get a video so i can see what you're doing?

[junior widget]

uh idk if ill be able to send it but i can try

idk how to record...

[junior widget]

@cinder spruce does the second wingman need the lighter gray color compared to the first wingman needing the darker gray? or is it the same darker gray color for more than 1 wingman

[cinder spruce]

no all the wingmen are the same dark gray
they're sorted automatically

[junior widget]

yea its bugging out for me

yea like i place one more of my growler with the dark gray color behind me

idk

its just not working for me

it is but its not switching through the other formation modes

oh yea for me they dont float

maybe thats why

the height offset doesnt change anything

they are still sliding around on the ground

[radiant lion]

Welcome to tm modding, where stuff doesn't work and noone knows why

[cinder spruce]

the one on the workshop uses the eyeball, are you using the 1x1 pipe?

[junior widget]

no i am using the eyeball block

[cinder spruce]

i mean when on the ground they usually dont stay up
when flying its fine

[junior widget]

like when i put on the v or any other formation mode on other than the line

they still make a line formation

doesnt matter what i change

all they do is go crazy

[cinder spruce]

hmm 2 things

• what settings are you using?
• where is the eyeball placed on the build?

[junior widget]

i put the eyeball piece as close to center of mass as possible (basically a block behind it) and also the only settings im changing is the distance and the formation modes at best

[cinder spruce]

rq can you unsub and resub to the mod to make sure u have the latest version?
i really dont know whats wrong

[junior widget]

alright

still didnt change a single thing

i just turned on the mod and changed nothing other than turn it on

and 2 of them just try to jump me

i tried changing the distance and that did basically nothing

so

yea

idk why this is happening

do i have to place them down in a specific order? or does that not matter

[topaz arrow]

Why does the place of where the eyeball is matter? Is it to allow some design variation for how aircraft fly, or is it a necessity from the code?

[cinder spruce]

you can only apply force or torque on a block, and not a whole structure

the closer to the COM the block is the more stable it is in general

[topaz arrow]

Can you not? Apply force on a block? Torque shouldnt matter where the block is, since torque, but i swear ModBlock.getStructure().addForce(x, y, z) works

I guess ill have to double check, but i swear the anti drag block uses that sometimes and works well

[radiant lion]

You can apply force on a structure, yeah, not torque

[topaz arrow]

Ah yes, makes sense

[radiant lion]

But torque still prefers to be applied near com else the com will receive weird forces

[topaz arrow]

Can you elaborate on the weird forces?

[radiant lion]

If a clockwise (just 2d) torque is applied, let's say to the right of the com the com will be pushed upwards, at least I'm pretty sure in unity it happens like this

Same reason as to why putting the tracker close to missile fins turns sharper than otherwise

[topaz arrow]

Ah, lovely

[topaz arrow]

I do not know about this

Wait, so tracker at the back of the missile = good???

That is... very unexpected

[radiant lion]

That's how I remember it, yes

[cinder spruce]

i had an interesting idea for a mod the other day

what if there was a mod that can create a recording and save the position and rotation of a build, and replay that recording by moving the creation through the saved points? could be interesting for custom missions with wingmen of sorts. might also be useful while recording videos

i might be able to try and do this using formation mod as a base

[cinder spruce]

alright ive mostly isolated most of the stuff i need, and added a quick way to step through manually defined frames with positions and rotations

strangely it feels kind of dampened when its travelling in the negative direction, is something up with the PID?

[topaz arrow]

If you attempt to do such a thing, i would also highly recommend allowing the data to be spit out into a format that can be copy pasted into desmos or sth, to show the flight path

[cinder spruce]

well first i have to figure out how to work reading and writing data to the dynamic data folder, i have not used it before

[cinder spruce]

alr managed to get something
you can see the footsteps where i ran around to record the path

[cinder spruce]

0 manual flying

surprisingly easier than i thought it would be

still need a way to save the replay, and maybe a better way for it to loop.
i had to manually fly through roughly the same spot for a decent loop

@hollow depot

[hollow depot]

gah daymn

[regal bear]

This is awesome! I'd love to have this system in Track Creator Plus to record fastest laps and be able to play them back as a ghost replay!

My original thought was to use a trigger box or non collision prefab as the ghost vehicle.

[cinder spruce]

i could probably reduce how many points i record lol

[cinder spruce]

i think this might explain why the wingmen in formation mod sometimes decide to form up 300m away

[scenic echo]

Super cool, that would also be good for a replay tool for racing

[cinder spruce]

it is kinda finnicky but can work super well

[warm canopy]

Man I need your help with the physics api I made lol, you seem to have mastered pid

[elfin yarrow]

awesome

[ivory agate]

Lmaooo

At least the lua stuff works but yeah it's definitely a maybe for all the tm stuff

[ivory agate]

Is there like a visual list of all the spawnables?

Or would I have to check myself?

[elfin yarrow]

isn’t there a spawnables document in the same folder as the modding documentation or something?

[ivory agate]

Yeah but that's the names

[cinder spruce]

https://trailmakers.wiki.gg/wiki/Modding:Spawnables

[ivory agate]

Hence the check myself

[cinder spruce]

oops wrong reply, mb terror

[ivory agate]

Yeah that's exactly what I meant, thanks

I'm assuming all transforms apply to these objects, so like scale translation and rotation

[willow hamlet]

anyone know if theres a planet map kind of mod? that has a round world, water, realistic gravity, and potential for orbital mechanics?

[elfin yarrow]

don't think so, there's at least one planet mod but they don't have realistic gravity or water

water is actually just a really big flat plane so you can't have water wrap around planets and such, idk about gravity though, i know there's the orb in the middle of space sector but i'm not sure about modding that kind of gravity in

[willow hamlet]

oki thnx

[formal crane]

<@&1123912996406706277> Modding Jam for 2026??? Help me answer some quick questions https://discord.com/channels/296562030624899072/1428696418935377920

[serene magnet]

I mean it sure would give me motivation to expand my map loader

Because currently it's just an optimized fork of trailmappers loader but I wanna add path movement support and such to it

[smoky sierra]

please i need help somone i am trying to import a map from somone else into trailmappers he sent me on dc the full zip file that you put into trailmakers but none of the files including the Map file inside of it are able to be imported into trailmappers

any ways to do this from my or his end

[paper bone]

Yes, there should be a Map.json file in the mod your friend shared

[smoky sierra]

let me check

no json file in the whole thing

ill send ss

[paper bone]

You need to put that file into Documents/Trailmappers/Saves/"your_map_name"/

[paper bone]

There it is

[smoky sierra]

i tried that file it recognises its there bc it doesnt say no file found or whatever but when i click import nothing happens

[smoky sierra]

ill try

[paper bone]

The import function is for maps from a different format

[smoky sierra]

ah alr

thanks man

[paper bone]

No problem

[smoky sierra]

ah i just needed to convert that file to a json file bc it wasnt one

[willow hamlet]

is there a way or mod to remove clouds on danger zone?

[near parcel]

No

[cinder spruce]

circle

[topaz arrow]

Man, makes me wish we could interact with logic to just give them better autopilots

[topaz arrow]

What if... you could check for the position of flight control surfaces and engines and whatnot on the build every once in a while, and then limit the forces based on those. Would require making an autopilot that knows how to fly a plane actually, but would make the planes react to damage

Would allow the recordings to be more interactive

[paper bone]

Or make the strength of the control surfaces very low on the build and apply a force on them

[topaz arrow]

Ye or that, that would give a more realistic feel for it, but would require a lot more math to simulate the angle you wanna have the fins at

[radiant lion]

I've already done that for cars, so applying torque on the surfaces so that they stay at an angle is pretty much done, tho managing to get a plane to go where you want is harder than a car

[paper bone]

[topaz arrow]

Ngl, i feel the worst part for ai creations flying around would just be having to deal with being a players structure (being able to interact with logic would be nice, but isnt super necessary). Not being able to essentially have a modded player thingy that has their own id for the sake of structures and such would be super painful to deal with, having to check whether it despawned, spawning it back in in the same place, etc

[paper bone]

Yeah using blueprints in mods currently is very jank.
Because the blueprints your mod spawns always need to be associated to a player which causes a whole lot of bugs.
#1385250615340306523 message

[topaz arrow]

Oh wow. Its MUCH worse than i imagined

[paper bone]

Yeah would be amazing if we wouldnt have to associate the blueprints to a player.

[topaz arrow]

Or, give us a modded player (like an id of -1 or sth

[cinder spruce]

@paper bone seperated tracks
took a lot more work than i expected

[paper bone]

Ayyy nice

[cinder spruce]

Recording of 2 separate tracks, and replaying them

[cinder spruce]

hmm
does json not play well with vectors?

i cant seem to get it to save properly

[radiant lion]

It might save the dot in the number as a comma instead and that breaks it

[paper bone]

Yeah i believe you can do something like this:

local jsonString = json.serialize(data)
jsonString = string.gsub(jsonString, "(%d+),(%d+)", "%1.%2")
tm.os.WriteAllText_Dynamic(savePath, jsonString)```

[willow hamlet]

Imagine if we had graphics mods or shaders that would be so cool

[hexed hawk]

anyone know if its possible to change the emission strength of the headlamp block through modding? they are never bright enough

[paper bone]

nope not possible

[hexed hawk]

aw that suckss

[ivory agate]

Then you'd need a compiler which complicates things for the team

[radiant lion]

@cinder spruce scrapman used the formation mod v2

he forgot to mention it was your version tho

[cinder spruce]

yoo fr?

2 scrapman features lsgo

[radiant lion]

https://youtu.be/HCxSWwOp7U8?si=_YFvB7X2AA3KmW2q

[cinder spruce]

i just watched it and he even switched to reading the new description halfway through

[radiant lion]

I'm guessing he started with the base one, then realised how unwieldy it is

[cinder spruce]

he had the new version loaded in at the start so maybe he just had the wrong one open on steam

anyway i have a few things to change/add
i want to try out a ground mode for ground vehicles so it doesnt shove into the floor

[radiant lion]

Should be as easy as disabling y axis, the code might already be there if I stole everything from the missile logic

[rancid epoch]

Hey, is there a way to interact with functional blocks? Like spin a servo or get the number on a number display through a mod? Or at least send inputs to a creation?

[radiant lion]

Interacting with logic was suggested, but it's not yet implemented

[rancid epoch]

Ok thanks, that would be super cool

[radiant lion]

If need be you can control servos by adding torque and read values with some servo or something+checking the rotation of a block on it, but they are not easy/compact

[near parcel]

You can also spawn objects in front of sensors, but it easily breaks with movement

[smoky sierra]

anyone know if there is a alternative mod to block editor like to get custom colours because the mod just corrupts builds it hasnt worked for a while

[cinder spruce]

don't use the set all or any of the options that say "use at your own risk"
they are kinda unstable and are the ones that corrupt builds

as for the color its an issue with modding which is getting patched in the next update

[smoky sierra]

ah alr

[hexed hawk]

So im interested in working on modding tm, ive looked around but i could finde how to make a mod using the lua

i found it

question, i dont think so, but is it at all possible to change the color of bullets? i doubt it but itd be cool

is there a list somewhere of the blocknames for modding?

[cinder spruce]

you can make a pretty quick mod to get the name of any block that you're selecting
might be a good introduction

[warm canopy]

Anyone know the dimensions of maps, like test zone etc. Grid squares. Its been discussed before but I cant find it

[paper bone]

Test zone is 15000 x 15000 iirc

[fallow fox]

All maps are 15 x 15 km with the space map being 25 x 25 km.

Each test zone square is 15 x 15 meters

[warm canopy]

test zone square you mean the large grid squares?

[fallow fox]

its from center of the black line to the center of the black line on the other side

[warm canopy]

I think this scale is ok, from looking ingame its about 4 barrels per small square

[warm canopy]

Do you happen to know the y heights of the maps?

[fallow fox]

iirc its 7.5 km, dont know about space

[warm canopy]

No I mean the spawn height

like test zone I think is y 300

[fallow fox]

test zone is 300, dont know about the other maps but the water is always at 0

[formal crane]

from what i remember space sector is equal length on all sides

[warm canopy]

Going to call it approx 200 for stranded

[topaz arrow]

oh man, i wish there was a 25x25km ground map

[radiant lion]

Iirc it's always 50

Can't confirm it tho

Unless that was from the bottom of the sea

[karmic oxide]

oof, sorry bout that trailmakers 😬 first time mod maker, tried making a team sensor block

I've realised where I went wrong, wont do that again 😅

[uncut glade]

anybody know why my cone is purple?

[radiant lion]

These latest updates the Devs have been removing some unused assets from the game files, I'm guessing they removed the texture but not the model

[regal bear]

Are you running the game with low quality settings? Some prefab assets have missing textures at lower quality settings.

[sturdy iris]

hey im trying to make my first mod but im having a hard time making the main.lua file and idk how.

[fallow fox]

create a text file and name it main.lua

[sturdy iris]

thank you stino!

[tribal gate]

I'm trying to make a mod that spawns a line at a block and rotates it so it aligns with it's face but I can't figure out how to rotate it correctly does anyone know how to get the line to be positioned and rotated so that it looks similar to the red one image

[hexed hawk]

whenever you finish this mod, i need it xD lasers for distance sensors is awesome

[tribal gate]

Yeah I'm making it to help me improve tracking

[hexed hawk]

coolio

[tribal gate]

If i finish it i'll upload it to workshop if you want

[hexed hawk]

up to you

[cinder spruce]

your rotation is unused, might wanna do something about that

[tribal gate]

thats because I tried to rotate it and it wasn't accurate. i'm pretty sure It only worked in build mode either that or I just didn't use it right

that code is a temporary solution, it spawns multiple lines in different directions instead of one line in the right direction. and I removed the code for rotating since it wasn't working and I needed to fix other things

[cinder spruce]

btw, the os lib is disabled in TM, i believe there is a time function in tm.os

[tribal gate]

thanks I found it

[cinder spruce]

also you should use SpawnObject for spawning prefabs, iirc SpawnCustomObject is for custom 3d models

[tribal gate]

thanks I fixed those

also I have just checked and GetRotation is only accurate when in build mode, once the block is out of build mode GetRotation will still get the rotation of the block but it will only return the rotation the block was in when it was last in build mode

[sturdy iris]

what did i do wrong?

[cinder spruce]

check your mods .log in the modding directory

[formal crane]

your second 0 in AddUiButton needs to be a string (identifier)

[sturdy iris]

did it and didnt change anything

[cinder spruce]

yeah the button setup looks like this, you dont need anything in data if you dont have any value to pass on

[formal crane]

i am forgetting how lua works but could also be you need to define your SetGravity function before the AddUiButton reference.

[sturdy iris]

yeah that would makes sense and it works!

thank you frans!

[cinder spruce]

oh lol i didn't think so for a sec because for some of the mods im working with it was setup kinda like this which works fine

[formal crane]

right haha

[near parcel]

ids can be any primitive type

[near parcel]

because the createui function defers the execution of the adduibutton call until after the function setgravity has been defined, so when the name is looked up in the global namespace it finds the function

[cinder spruce]

yeah i figured

[cinder spruce]

here's what i think you should do,
this model is just a simple cube, 1 x 0.1 x 0.1, with its origin at one end of cube
makes it a bit easier to position and orient the line, since the origin is at the end.

you can load it with tm.physics.AddMesh("line.obj", "line") and spawn it with tm.physics.SpawnCustomObject(pos, "line", "")

as for the block rotation, i believe it is in local space strangely

[cinder spruce]

function GetBlockRotation(block)
    local forward = block.Forward()
    local right = block.Right()

    local relativeX = forward.x
    local relativeY = -forward.y
    local relativeZ = forward.z

    local angleradY = math.atan2(relativeX, relativeZ)
    local relativeangY = math.deg(angleradY)

    local relativehori = math.sqrt(relativeX * relativeX + relativeZ * relativeZ)
    local angleradX = math.atan2(relativeY, relativehori)
    local relativeangX = math.deg(angleradX)

    local W0 = tm.vector3.Create(forward.z, 0, -forward.x)
    W0 = W0 * W0.Magnitude()
    local U0 = W0.Cross(forward)
    local Angle = math.atan2(-U0.Dot(right), W0.Dot(right))
    if Angle < 0 then Angle = Angle + math.pi * 2 end
    local relativeangZ = math.deg(Angle)

    return tm.vector3.Create(relativeangX, relativeangY, relativeangZ)
end

here i made this function based off something from jess's mods, it gets rotation from a block in world space from the forward and right vectors

[tribal gate]

Thanks this works perfectly

[radiant lion]

W0=W0*W0.Magnitude()
What was I thinking, that's not how you normalise a vector

But if it works it works

[sturdy iris]

how would i go about making it so that i kill all players alive?

[paper bone]

using a for loop and looping over the table that is returned from tm.players.CurrentPlayers()

this website is fairly usefull for getting a overview of the available functions
https://mods.trailmakers.ludixi.com/docs

[sturdy iris]

but how do i make it so it goes through the list/table?

[paper bone]

with a for loop
maybe look at the lua documentation for a introduction to the language

https://www.lua.org/pil/1.html

[formal crane]

quick lua from memory so might be wrong

--first get the player list
local players = tm.players.CurrentPlayers()
for i, player in ipairs(players) do
  -- now `player` is one element in the players list

  -- you can get the playerId from the player object
  local playerId = player.playerId

  -- then call KillPlayer for _that_ specific player
  tm.players.KillPlayer(playerId)
end
-- this will be done for each element in the `players` list

[sturdy iris]

this works thanks frans! i was trying to figuer it out for over 40 minutes to no avail

[formal crane]

first trryyyyy

[elfin yarrow]

will there be thingy to do block bans in the next update?

[formal crane]

No

[elfin yarrow]

aww

would be great

[formal crane]

(but i very, very much wanna look into it)

[warm canopy]

I also would love that feature

[elfin yarrow]

augh

can i just shove like a null value or something on that last one, i don't want a sprite

[warm canopy]

Yeah

You can just leave it as ""

[elfin yarrow]

oh okay

it still fails to invoke ui callback lol

[cinder spruce]

i dont think you even need to put it

just remove the last argument entirely

[elfin yarrow]

i mean, yeah it worked with only 2 parameters (header and the second thingy) but someone said to fill all 4 parameters to fix invoke ui callback

[near parcel]

Fully omit any value and it will use a default icon

[elfin yarrow]

ok

[scenic echo]

Banning blocks would make making campaigns a lot easier

[formal crane]

🤞

[paper bone]

Whenever we suggest a new modding feature to frans we now must always present how it specifically would make it easier to make campaign mods :P

[elfin yarrow]

i'd just use it to ban specific blocks automatically for things like demo derby

with the persistence of data on the mods (idk what it's called, where you leave a session but the mod still keeps track of stuff) you can probably make a block ban presets mod too

but for now, i'm gonna try making a mod to reload custom unguided weapons like bombs by spawning the blueprint under the player with an adjustable offset

that's the plan at least, i don't have the slightest clue as on how to implement that

[topaz arrow]

i thought of doing such things, but never had the time to try. good luck, and may lua be with you!

[warm canopy]

The current method of destroying peoples builds if they use the wrong block is a very rough approach

[formal crane]

I would say 95% of what is being suggested here is pretty sensible and worth adding.

I have been wanting block banning/restrictions for a very long time for the sake of gamemode creation; creating constraints in sandbox games it literally the way forward to faciliate play 🙂

[elfin yarrow]

i've got the time to try but not the skill to actually do it, not yet at least
-# but i'm not gonna promise anything since i'm not known for keeping promises like this lol

[paper bone]

I know its just a joke since you have said previously that you would love to see more campaign mods

[formal crane]

just give me a tech tree mod man

KSP style researching or whatever

[topaz arrow]

space sector

[elfin yarrow]

that would be awesome

[paper bone]

If we could change the skybox we could make a better more realistic space map

[topaz arrow]

having builds belong to no player/modded player could allow for custom enemies on the map... (if this was possible i would so make AI enemies for the Custom missile mod)

[paper bone]

Or traffic

[topaz arrow]

that too, tho for enemies i think its even more clear, as stuff like locking on with autolock wouldnt work on builds from the same player (maybe? am actually not sure, but i assumed so since same team and whatnot)

[paper bone]

No i think it only doesnt target a build when there is a player of the same team inside (atleast from my in game experience)

[topaz arrow]

maybe, i dont remember, havent used autolock in a while

[paper bone]

But it would resolve a lot of the currently existing bugs related to when using blueprints as if they werent owned by a player.

[hexed hawk]

just wondering before i start later, but is it possible to adjust the power of the propellors? ive seen it for the jets and thrusters, but never seen one for the propellors at all

[warm canopy]

ModBlock.SetPropellerPower(power)

[sturdy iris]

how do i make it so i can use the ModStructure.AddForce(X, Y, Z) i have tried alot but i can manage to get it to work can anyone help? and just in general the ModStructure

[radiant lion]

Can you be a bit more specific? What's the plan? All modstructures or a specific one? What about the modTransform, that has nothing to do with structures

[sturdy iris]

for now i want to make vehicles the person is in accelerate in a direction really fast (up for example)

and with modtransform i mean modstructure my bad

[radiant lion]

Ok, that's decently straightforward, you have to call tm.players.GetPlayerSeatBlock(playerId) to get the seat a player is in, it will return either nil or the ModBlock of the seat (add a check), at that point you can do ModBlock.GetStructure() and add force on said structure, if you want a constant force do it in the update function, else do it wherever

[sturdy iris]

im trying but i dont know how to continue from here.

[radiant lion]

Do you have the docs at hand?

[sturdy iris]

i got the trailmakers_docs.lua and a lua document

[radiant lion]

ok, that's good

[radiant lion]

first tho, here tm.players.GetPlayerSeatBlock(playerId) returns the seat as a ModBlock, you are gonna have to store it somewhere, same for the structure, so either do something as simple as

local structure = seat.GetStructure()```
or you could do directly 
```local structure = tm.players.GetPlayerSeatBlock(playerId).GetStructure()```

[sturdy iris]

and from here i can do structure.ModStructure.AddForce(X, Y, Z)?

[radiant lion]

just structure.AddForce(x,y,z)

in the docs the name ModStructure is a placeholder for whatever variable that contains a ModStructure you have

same for the other classes

[sturdy iris]

it works! thank you so much ive been trying to figuer it out for the past 4 hours.

[sturdy iris]

ah okay! i think i got confused from there

[cinder spruce]

don’t hesitate to ask for help here when you need it :)

[topaz arrow]

Stupid but funny solution:
Create a program that poses as a player, can join and leave, and not much else. Kinda like how games have the "X game dedicated server" on steam as a seperate thing, tho here it would be a dedicated fake client

[cinder spruce]

@warm canopy
?

[elfin yarrow]

banned from ludixi? what did you do??

[sturdy iris]

i got the same thing

[cinder spruce]

i believe whatever host he's using kicked him out

[sturdy iris]

hmmm why is it not working? it should work i think but i keep getting failed to invoke UI callback

[cinder spruce]

playerid doesn’t have any functions, its just a number

i believe you can get transform from a function under tm.players.GetPlayerTransform or something

i cant check docs rn cuz terrorsouls site is down :(

[formal crane]

tm.players.GetPlayerTransform(playerId).GetPositionWorld()

something like that

[sturdy iris]

wait that indeed is there... there is no way i would have kown because the website is down

[scenic echo]

Run the mod called documentation, it will generate a file called documentation, in the folder "mods", with all the functions

[cinder spruce]

well im on phone, otherwise i would have the docs file on my pc

[sturdy iris]

okay it now works. i used: tm.players.GetPlayerTransform(playerId).SetPositionWorld(TeleportX, TeleportY, TeleportZ)

[cinder spruce]

anyway do you have this thing setup from alva? https://discord.com/channels/296562030624899072/1141061251796041799

[sturdy iris]

Yeah I do but I had the old version it seems as most functions weren't on it

[sturdy iris]

hmmm it only works when im not in a seat is there anyway to make it with the whole vehicle?

[cinder spruce]

you aren’t able to set the position of structures unfortunately

only apply forces, which is what formation mod does pretty much

[sturdy iris]

let me guess it also uses alot of math?

[radiant lion]

Just use this https://github.com/ALVAROPING1/Trailmakers-API-LuaLS/blob/master/library/tm-api.lua

[radiant lion]

Surprisingly only force and not torque, gotta use blocks for that

[warm canopy]

Don’t panic I’ll fix it when I’m home. I’ve been out all day

Hosting autobill didn’t go through so they suspended my account temporarily

[cinder spruce]

rip

[warm canopy]

Should be fixed now

[scenic echo]

yeah, it works

[scenic echo]

@warm canopy I didn't know you could submit guides on your website, that's super cool

[regal bear]

You can teleport a player and the structure they are seated in if you use a spawnpoint

[sterile escarp]

YO can a trailmaker get some help

[radiant lion]

The preview image has to be less than 1mb

[sterile escarp]

https://tenor.com/view/kitty-cute-kitty-cat-uwu-perhaps-i-cried-gif-13073632

[sterile escarp]

thats good to hear cause mine is 1.02 MB how do I make it smaller its the base image you get with just not uploading one x.x\

[paper bone]

there should really be some more instructions when uploading a mod lol

[radiant lion]

Or at least better errors...

[radiant lion]

There are tons of sites that compress images

Loose some quality, but it's no big deal

[sterile escarp]

so I did this, still at this. is there something I need to do to get trailmakers up to date with the new preview image?

[paper bone]

The folder you are showing here isnt the folder that will be uploaded

Changing things in that folder wont make a difference

[sterile escarp]

so I need to find it in trailmakers directory somewhere

[near parcel]

install_dir/mods/mod_name

[paper bone]

You need to change the preview image that is in the folder with the name of your mod here

[sterile escarp]

https://tenor.com/view/i-used-to-pray-for-times-like-this-i-used-to-pray-meek-mill-dreams-and-nightmares-dreams-and-nightmares-michael-jordan-gif-4600240804856944817

THANK YOU SO MUCH @paper bone @radiant lion

[cinder spruce]

that looks like a peak map might have to check it out later

[topaz arrow]

ok, in what units is the force? newtons? what is the gravitational strength (at 1.0 gravity)?

from my experiments, power of around 2.1 (2.1*deltatime applied every update) seems to make a 0.8kg pipe levitate, but the acceleration seems to be 14 m/s^2, at least if my acceleration based on velocity based on position shows, but like, that is incredibly chaotic and weird and idk if units are wrong or if im a dumbass or whats going on

[cinder spruce]

14m/s/s is the correct gravity in TM

[topaz arrow]

hmmm, that is very weird

ok, so eyeball math:
V/0.8kg=14
V=11.2
2.1*X=11.2N
X=16N/3

so one TrailNewton (as in the unit strength you use in the addforce function) is roughly 16/3 newtons

but measuring it with a different method gives 4.97ish as Newton to TrailNewton ratio?

[topaz arrow]

crisis resolved, the weight was actually 0.15, not 0.8

[cinder spruce]

what

my mod isn't showing up in steam or the in game ws?
https://steamcommunity.com/sharedfiles/filedetails/?id=3601057434

wth

[scenic echo]

I don't see it either, very weird

[hard shore]

I was only able to find it when I went through your steam profile

[radiant lion]

Shows up here

[formal crane]

no problem here either (web/steam view, didn't check ingame)

[scenic echo]

I see it now too, i guess it just took a long time

[cinder spruce]

hmm idk
ig took several hours to actually show up

[hexed hawk]

will we ever possibly get a way to make custom light sources for maps?

[scenic echo]

maybe in future updates but not any time soon

[hexed hawk]

how long until trailmappers update? i know its thirdparty i think, but still

[scenic echo]

idk, but falshbulb needs to update the modding api for custom lights to be possible not the third party software trailmappers

[hexed hawk]

yeah, in the meantime, anyone know a good way to imitate LED lights in trailmappers?

specifically a LED floodlight

[cinder spruce]

theres only a few objects that give off light,

• Chest
• Lava
• Flamethrowers
• Salvage
• Power core crate

you could try experimenting with those

at least those are the ones i found

[hexed hawk]

only the powercores give off blue light, and i need white

8 powercores to make that light

[cinder spruce]

some of the other lights are a bit warmer, you could try combining them to cancel them out?

[hexed hawk]

its better...

i wish there were more colors, but i also wish alot of things, thanks for the tip AJ, it it greatly appreciated

also, AJ, these give off a small amount of light too

[cinder spruce]

those are just emissive, they dont emit any light onto other objects

[hexed hawk]

aw man

[cinder spruce]

nah this doesnt feel like trailmakers anymore

[cinder spruce]

tm.physics.SpawnPointLight(position: ModVector3, range: number, intensity: number, color: ModColor) would be sick to have

[radiant lion]

You are forgetting angle of the light cone

[scenic echo]

can anyone give me an example of how to read information from a file and write it into a table with mods? i haven't really used it so idk how to do it.

[near parcel]

local content = tm.os.ReadAllText_Static("foo/bar.txt")
tm.os.WriteAllText_Dynamic("foo/bar2.txt", content)

[cinder spruce]

its a point light

i suppose a spotlight could be something seperate

[cinder spruce]

the moonsharp json lib is probably what you need

you can use json.serialize(table) to convert a table to a json string, and you can use the functions given by alva to actually write the data to the data dynamic folder.

to read the data and convert it back to a table, you can use the read function, and use json.parse(string) to get the table back.

local data={}

function saveData()
    local jsonString = json.serialize(data)
    tm.os.WriteAllText_Dynamic(“save.json”, jsonString)
end

function loadData()
    local jsonString = ReadAllText_Dynamic(“save.json”)
    data = json.parse(jsonString)
end

something like this i think

[scenic echo]

thanks, i'm gonna try it

[scenic echo]

i'm having trouble with data = json.parse(jsonString) it gives this error there Unexpected token : '='

[fallow fox]

I dont know if its like this in TM modding but json is "key": "value" , there shouldn't be a '='

[cinder spruce]

i probably messing something up i did that from memory

uhh

[cinder spruce]

the parse function returns the entire table though

[scenic echo]

Ok

[scenic echo]

Thanks, it worked

[tribal gate]

Does anyone know why the object spawns farther ahead of the block when the player isn't near the build. It only spawns correctly if it either isn't moving or the player is near it.

[near parcel]

objects far away from the player update less often

[tribal gate]

then should I make it have an offset that scales with the distance

wait but if they update less often when are they in front of the build instead of behind

[hexed hawk]

is it possible to affect player fov in first person with a mod?

[fallow fox]

is there a list of all spawnable object names?

[radiant lion]

tm.physics.SpawnableNames()

[fallow fox]

thx

[cinder spruce]

i think in 2.2, spawnable names, audio names, and docs are auto generated in the mods folder from now on

neat

[cinder spruce]

imagine we could have space sector render distance in other maps
you could literally see stuff from miles away

[willow hamlet]

is there a mod to lower some drag of blocks?

[topaz arrow]

afaik not a dedicated one, but it can be done with mods. the experimental branch of the custom missile mod has something kinda like it, but its done in a janky way and is meant for building missiles only. i know that @radiant lion is messing with a properly made custom drag blocks for the new custom missile mod, but its not yet available.

if you have some basic knowledge of modding or just programming, it shouldnt take long to make a mod like that yourself

[formal crane]

@cinder spruce told me this was great reveal, so sharing Stino's clip here to show the new UI option 🙂

[scenic echo]

Awesome, more ui is always welcomed

[sturdy iris]

peak cant wait for that new UI

[radiant lion]

can confirm what obo said, just, it's possible but noone exist yet... but i'd reccomend waiting as setting drag right now has some side effects

[scenic echo]

Is there a way to know the drag of blocks without having to calculate it?

[formal crane]

Only in 2.2

[elfin yarrow]

only 7 years days away

[topaz arrow]

Yesnt, as apparently even the 2.2 values are not what i would expect (as in are not N*(m/s)^-2.2), or have some other multiplier chicanery

[scenic echo]

does ModBlock.GetMass() give the weight of the blocks? i'm having trouble using it, like the weight is around 5 times less than the in game weight

[elfin yarrow]

i’m assuming it gives the weight in the engine, like how melvin weighs 150kg in the engine but is heavier in trailmakers kilos?

-# disclaimer: untrusted source, me

[formal crane]

Sounds pretty correct
-# disclaimer: I actually dont fully know, but I can see it returns the RigidBody Mass but I dont have the full overview of what "weight" actually yet. You might be missing some additional value to figure out the actual "weight".

[scenic echo]

on the block 1x2 it's accurate if i do ModBlock.GetMass() * 5 but for straight suspension i have to multiply by 10 to get the accurate weight

why does everything have to be inconsistant

[fallow fox]

I think i saw somewhere that it only returns the weight of 1 part of the block, so you get the weight of half the suspension

[scenic echo]

so every part that has something moving is half the weight?

[fallow fox]

Dont know if its half

[scenic echo]

the weight i get from lrage hinge through mods is 0.78 but the in game weight is 1.1 so yeah not half

[ivory agate]

how does parenting work? since you can't set the transforms yourself you'd have to do something else

Do you need to like make the matrices then convert them back so you can supply the r, t and s manually?

[radiant lion]

Parenting was suggested, but as of now that's the best you can do, set the transform values every frame based on those of the parent and an offset you give

[ivory agate]

Like this

[serene magnet]

YES YES YES YES

More UI!!!

[hexed hawk]

at some point would someone be willing to help me set up the modding stuff? i haven't been able to figure it out

[fast oyster]

what is an acceptable amount of vertices for a custom map?

[fast oyster]

guys my map isnt mapping

@cinder spruce do u know the problem?, sorry for tagging u if ur busy or something

[paper bone]

Thats too many triangles

At some point if the model has too many triangles trailmakers will just do bs like that

[fast oyster]

whats the max amount?

[fast oyster]

like 10000 or like even lower, 5000?

[paper bone]

I dont actually know

[fast oyster]

i guess trial and error is the only way

10k tris works fine

[sturdy iris]

I think it's like max 1 mega byte but idk

[scenic echo]

That's for tecture i think

[fast oyster]

is there anyway a icould anchor a 3d model to a build?

[scenic echo]

the easiest would be with 3dModelObject.GetTransform().SetPosition(position)

[cinder spruce]

1000 workshop mods 🎉

[hexed hawk]

should ask for a Super Modder role xD

[cinder spruce]

this is all mods uploaded not just from me xd
i only have a few

[hexed hawk]

oooh, too bad i thought you were cooler lol

(this is a lie, youre sick xD)

anyways, can someone tell me how to access the modding API? i cant figure it out

ive been given links to the Wiki page, it dosent help

please someone?

ok, ummm, how do i save the code and get it into trailmakers? i found the mods folder and saved my mod to it, but its not showing up ingame

@cinder spruce how doeth i get a mod ingame?

[topaz arrow]

this is how u enable them

in the mods folder, add a folder, name it sth, then into that add a main.lua file

[hexed hawk]

thats the problem though, its not showing up ingame

[hexed hawk]

wait, whats in the main.lua

[topaz arrow]

the code you want to run

the code of the mod

[hexed hawk]

it now shows up in game, but it didnt work, im cheking my coding now xD

[hexed hawk]

does anyone have a list of all the blocks/ what they are called for modding? im trying to detect if someone uses more than 2 large flak

i cant find the block ID

[sturdy iris]

I don't exactly remember how

[topaz arrow]

ModBlock.GetName()

[topaz arrow]

you can print to the log file the block you selected in build mode

[ivory agate]

65536? right?

I don't remember if that was tri count or unique vertices

[paper bone]

no idea

[cinder spruce]

32767

[ivory agate]

Why would it be singed?

Thats actually so weird

[fast oyster]

Is there anyway I could get ps5 grass on pc?

[gritty jasper]

do you guys have any menu api or yall use the unity debug UI?
I think I might port mine and make it open source, tho it uses ML

[sturdy iris]

https://mods.trailmakers.ludixi.com/docs

it uses lua

[gritty jasper]

alr

[candid crescent]

Is there any way to make a mod that allows you to use any seat underwater?

[topaz arrow]

Nope, not a power the mod api has (unless there is sth new in the tank tracks update)

[candid crescent]

Yeah that’s what I figured, I looked through all the stuffs and didn’t see anything

[sturdy iris]

I hope that will be the case tho

[ivory agate]

For steam uploads right? No way it's for just textures as-is because that's literally nothing

[radiant lion]

It's for the preview image

[formal crane]

Not a thing for 2.2

[ivory agate]

How fast is it to set the position rotation and scale for an object? I'd like to have an idea before even bothering with some ideas I have

(I can precompute the transformations so that part is not a big issue)

(the project in question is kind of related to this :3)

[scenic echo]

When i had like 4 objects moved every tick, 60 ticks per second, my game started to slow down(server fps went from 60 to around 30-40), but i have a pretty bad pc and also it was every tick

[ivory agate]

Oh

Id need like at least 100

[radiant lion]

You can try but I doubt 100 will be very good for performance

[ivory agate]

It might not be possible then unfortunately

They'd need to be updated at least 30 times per second unless there is like a way to do lerping at a native framerate

[fallow fox]

how do you upload mods? mostly how do you set the thumbnail and description?

[warm canopy]

If the custom object is a rigidbody then you’ll get much smoother frame rate

[ivory agate]

It won't need phyiscs

As I said, all movements are known

Unless that somehow changes things

[warm canopy]

If it’s a custom object though even if it’s static , if it’s a rigidbody it’ll sync with the physics engine

Much smoother movement than if it wasn’t a rigidbody

[ivory agate]

Okay so would keyframing be "static"

or a rigidbody?

[warm canopy]

What are you trying to make?

[ivory agate]

Just something that can replay animations

So given
Pos A at time 0
and
Pos B at time 1
I would need to interpolate linearly between them

[warm canopy]

Okay, but what I’m saying is that if it’s a custom mesh and set to rigidbody. You won’t get the teleporting affect like you do when it isn’t

[ivory agate]

So what does it look like when using a rigidbody? can you explicitly tell it how to interpolate or does it just do it automagically?

[warm canopy]

You can use the lerp function

[radiant lion]

You can do it from the host options in-game, just add a preview.png file (less than 1MB) in the mod's folder, it will make you choose a mod directory, it should be "mods/modname" then it will make you choose a proper name and description (you can always change it from steam directly)

[fallow fox]

thx

[ivory agate]

Oooooh I see that makes my job much easier

[warm canopy]

tm.vector3.Lerp(vector, otherVector, t)
Linearly interpolates between two vectors.

Parameters:
vector ModVector3
otherVector ModVector3
t number
Returns:
ModVector3

[ivory agate]

Wait I don't see how this would make it smoother? since this is just lua side right

[warm canopy]

If you are just updating the position normally every frame but the object is set to rigidbody it will be smoother

Try it

[ivory agate]

okay wait, is this a method you can use on a mod object or is it just a function for vectors?

Just saying "it's smoother" is completely meaningless if I don't know how or why it's smoother

[near parcel]

It's a function on vectors

[exotic nacelle]

Are there any guides floating around on how to make a custom map?

Probably won’t actually end up making one but I’d love to give it a try

[formal crane]

LittleCornDog has a video on Trailmappers, but there are also other ways of making maps like TrailEdit whatnot
https://youtu.be/o_3_NpOSLzQ

[exotic nacelle]

Ty!

[exotic nacelle]

are custom maps constrained to the borders of the test zone?

im guessing so

[scenic echo]

Yeah, you spawn your map over a existing one and the barrier remains,

[exotic nacelle]

Alr

[ivory agate]

There's no way to do stuff in clip space right? I know I'm asking weird questions but like I'm mostly just thinking about stuff

Would mostly need that since it's not possible to get all the variables that go into defining the camera right? I guess the best I could do is just get the camera data and have all the data I can't get be manual for the player to adjust or something

Though I didn't see anything on how to get the camera data

and you can't seem to get the mouse position (only when it's down or up), hm

[warm canopy]

You have to do something really janky to simulate mouse controlled look direction

[ivory agate]

Yeah that's what I thought

[warm canopy]

You have to basically create a camera rig seat that uses mouse input for movement then measure the players rotation

[ivory agate]

guh

[ivory agate]

Added function to interpolate between colors
tm.color.Lerp(ModColor a, ModColor b, float t)
Is this just (a + b)/2 or is it the square root correction thing that literally no one gets right

[serene magnet]

https://tenor.com/view/yess-yes-gif-25420589

[formal crane]

no clue, just used the one that Unity offers

https://docs.unity3d.com/2022.3/Documentation/ScriptReference/Color.Lerp.html

[ivory agate]

Okay yeah then it's probably the "incorrect" (but standard) one lmao

[formal crane]

But yeah colors always bad everywhere

[ivory agate]

Yeeah

Well this is another version but I see no reason why they would ever change it

[radiant lion]

pretty sure a few minor things are missings

[formal crane]

Forgot the fixes
#1441041011970281533 message

But they added now

[radiant lion]

like the getDefaultDrag or quaternion equals

[ivory agate]

It's a newer version, the 6.0 beta thing unity seems to be doing I think

But I'm not sure

[radiant lion]

no, i mean from the changelog

[ivory agate]

oooh okay

nvm

my bad

[formal crane]

Added the getDefaultDrag now 🙂 Thanks! Been hectic lately hehe

[radiant lion]

also the set wind is missing

[formal crane]

DEAR LORD

[radiant lion]

:)

[formal crane]

Done!

[radiant lion]

serious question, how are the changelog made? memory, some list stored somewhere...

[formal crane]

In terms of modding I have a Document where we add to it every time we complete a task.
But it got a little side tracked here in the end..

We are actually talking about how do do it better overall for the game.. As it is hard to parse commit messages into changelogs. And sometimes things are a registered task.. Sometimes it it made adhoc.. So it is REALLY hard to track changes.

[radiant lion]

i see

[formal crane]

The formatting completely fucks up copying from Confluence to Discord so that is intensely annoying.

[radiant lion]

time to make a script that converts from comfluence to discord then

[formal crane]

I would love to know how other game companies does it 👀

[formal crane]

I refuse to touch any of Atlassians APIs

[radiant lion]

i was thinking more of an external app where you paste the stuff from confluence and lets you copy a re-formatted version for discord

[near parcel]

In OSS projects at least semantic commits work well. Tldr: enforce commit messages to follow the syntax <type>(<scope>): <description> (it's a bit more flexible than that), then you can use pre-made tools that take those commits and split them into lists of features, fixes, breaking changes, etc, potentially divided by scope

[formal crane]

Yeah we were talking about it; it would be ideal to have it like that.. But a lot of times we have stupid commits here and there.. We moving a little faster than what you do in usual online projects. Sometimes compile errors are pushed.. And perforce you can't really do amends the same way as you can on git.

You also have to remember more than half the commits are artist doing "Updated model.fbx" or whatever and you can only get SO FAR with semantics like thos

[near parcel]

chore(models): update X.fbx. Then it's a simple filter (usually tools already filter out all chore commits, also works for formatting, refactor, update libraries, ...)

[formal crane]

It took us 2 years for people to add links to the related task URL so not sure how long this would take for people to get in the habit of :p

[radiant lion]

while here can you explain this

Player userdata will now contain Player Id, Player Profile Id and Player Name.
pretty sure the logs don't explain what the components of userdata are and stuff like .name .username or .profileId isn't working

[near parcel]

If you want to get changelogs somewhat automatically, you need to enforce some consistency somewhere. If you can only assume commits are random letters you can't do much without and over-engineered AI that can generate descriptions from raw diffs. There are tools to automatically validate things if they don't match the syntax to help enforcing it

[near parcel]

Does it work in game?

[formal crane]

local players = tm.players.CurrentPlayers()
players[1].playerId
players[1].playerProfileId
players[1].playerName

The docs will include this in later version; I just haven't landed the new docs yet!

[ivory agate]

The only times i've heard about atlassian it's always been about negative things lol

[scenic echo]

Did setting health get fixed?

[ionic jacinth]

These modding additions are very interesting and will probably get me to do modding again.
The setdrag functions for blocks will be especially useful for rebalancing certain blocks using an excel spreadsheet and for incentivising players to use certain blocks over others: e.g adding drag penalties for thick wings so that gliders have skinny wings like in irl (aka narrow 'wing chord').
The wind function will also be super useful, although a per player version would still be appreciated!
Overall this is the right direction for trailmakers to head in!

[formal crane]

No, but hopefully soon! 🙂
I have a bunch of changes that I just need to land for next update

[formal crane]

More to come 🙂

[warm canopy]

Updated the functions on my modding site

[surreal junco]

After update, spawn locations on custom maps are broken

[scenic echo]

for me it's fine, can you link the map you are having trouble with?

[surreal junco]

my map oflex offroading experience extended

it is spawning at 0 instead of at the spawn point

not sure how to fix it

I used trailmappers

it is only failing on the first instance

after that, holding backspace lets you get to the right spot

just thought it was an odd behavior

[warm canopy]

Havent had this issue even with trailmappers maps

[surreal junco]

aw

that is the message every time someone joins

[warm canopy]

Whats the error in the your mods folder (.log file)

[scenic echo]

for me in single player it loads fine

[surreal junco]

is that the errorlogs.gz

[scenic echo]

it's in the mods folder

[surreal junco]

2025-11-20T13:03:51.4714219-05:00 failed to invoke OnPlayerJoined
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object.

[scenic echo]

i have no idea what it means

[surreal junco]

Yeah... me too

[formal crane]

1. send link with map
2. write me exact steps to reproduce it
   will check it out next week

[surreal junco]

Thank you https://steamcommunity.com/sharedfiles/filedetails/?id=3563372295 To reproduce it, start the map, with the name 0ff Roading w/banned blocks, turn on player deaths, ban all the blocks that are flight or gyro blocks, and closed seats. then when people join, it has them join at 0,0 instead of the spawn point, and has the error message Failed to invoke on player joined. Could be an issue with the spawn location piece in trailmappers

That token has always been weird anyways. It makes people spawn on top of each other, no error handling.

[near parcel]

what is tm.color.RGBToHSV supposed to do? It takes rgb values as input, but since it returns a mod color you can only get rgb values out and it should behave exactly like the normal .Create() constructor (specially since the alpha arg on that is optional). Currently it seems to always return RGBA(0,0,0,0) as well

[near parcel]

my IDE docs have been updated

[sturdy iris]

im trying to randomise a vector 3 for the new wind function but i recieve this error

[formal crane]

your function needs to return a ModVector3. Right now it returns a Table

also you invoke randomWind() with no args, meaning no numbers, which throws your error

[sturdy iris]

okay i fixed it now (i shouldnt have asked GPT for help)

[warm canopy]

If anyone has any useful bits of code, you can add them here if you want. https://mods.trailmakers.ludixi.com/snippets

Might be useful to some

[sturdy iris]

i will upload my whole project when im done and have published it :)

[hoary skiff]

Holy Jesus over 11k messages in this forum chat I never check

[warm canopy]

Having issues with hosting provider, they randomly decided to rollback the whole server overnight 😠

[warm canopy]

Fixed. Lost some snippets that I added but thats about it.

[scenic echo]

alright, then it's good that i didn't upload any yesterday

I think these are the libraries if you still want to use em #1141357451887779910 message

[tribal gate]

thanks

[sturdy iris]

for if you want the library on visual studio use the library from in the trailmker files (C:\Program Files (x86)\Steam\steamapps\common\Trailmakers\mods/trailmakers_docs.lua)

[warm canopy]

Added a bunch more snippets: https://mods.trailmakers.ludixi.com/snippets

whats the gravity call i would add to a mod that will take the world gravity value

[sage orbit]

is stinos sled mod available?

Welcome to our humble chat

[sturdy iris]

ive been trying for a bit but i cant seem to get a simple looped timer going that works with a Boolean and then call a function can anyone help me with that?

[scenic echo]

i can

[scenic echo]

Time = 0
function update()
  Time = Time + tm.os.GetModDeltaTime()
  if Time >= Delay then
    Time = 0
    --your code
  end
end
``` something like this should work

[scenic echo]

how can i get the forward drag from ModBlock.GetDragAll() and from ModBlock.GetDrag(aerodynamicBoxIndex)? i'm having trouble with them

[formal crane]

From memory, but I think this is where it landed.

local box = ModBlock.GetDragAll[1]
local forward = box.forward
--same as
local box = ModBlock.GetDrag(0)
local forward = box.forward

[scenic echo]

thanks

[willow breach]

Hello does anybody want to help me with track switches? Im not very good at coding. The reason why, I have a two month map project that sadly does not work after the update. If someone could help me to make a custom train switch, where the player can decide where to go, would make my day.

[upper niche]

Would it be possible in any way to let a VR headset and/or controllers control a build? Totally not because I want to turn into a Dreadnought I made

[paper bone]

Not through the modding api. You could try and use some kind of layer to translate your controller inputs into something readable by the game. But i dont really know much about how that works exactly

[regal bear]

I'm not the best coder out there but I'm happy to help out

[regal bear]

It might be easiest to simply switch "setIsTrigger" on and off for parts of your switch tracks depending on which way you want the train to go

[sturdy iris]

@warm canopy the libraries on your website dont work btw (translated: File was not available on the site)

[warm canopy]

I'm aware ive taken them down whilst I work on them more

[scenic echo]

right now i kind of want to make a mod the adds stalling to trailmakers, just really simple if the aoa is over 25 degrees it makes all blocks have 20% of the drag up and down but the thing that i don't really know how to do is modifying the up and down drag of the creation without modifying the forward and backwards or sideways drag of it. So if i change the bottom drag of every block it will change the bottom drag of every block but if a block is rotated it will not be the the bottom drag being changed, compared to the vehicle

[radiant lion]

Easies way is probably to compare block rotation to player rotation, and you either just use some Ifs for the 90° if you want something simple, else you'd have to use sin and cos to also get the odd-rotated blocks

[scenic echo]

could i use ModBlock.GetRotation() work? it does give the local position of blocks

[radiant lion]

Oh right, yeah, you can do that

Not exactly sure how it works with stuff on hinges tho

[regal bear]

@formal crane Just to confirm - we can't use SetIsTrigger() on objects spawned with tm.physics.SpawnCustomObjectConcave right?

[formal crane]

Nope. PhysX does not support concave triggers.

[regal bear]

Thanks, thought so. Makes things tricky. Any news on giving us proper no collision for any object?

[formal crane]

Hasn't been high priorities yet, but I will keep it in mind for next year's planning.

[warm canopy]

Do you think people would be interested in a faction-like territory mod? It requires using my trailbridge client for the server host. Basically factions would have territory that they can claim etc. Not sure how Id fully handle whats considered territory etc

[elfin yarrow]

that would be interesting

[dusty umbra]

Keep this idea in your head

Ok that sounded mean, just we might get more cool stuff next year that would make that idea cooler. (not confirming anything, just speculations so far)

[elfin yarrow]

-# ability to ban blocks from the api ?

[dusty umbra]

I said to much, I'm out, Frans save me

[warm canopy]

Id love some sort of way of mods storing to a central data point that. It opens up a bunch of possibilities. My trailbridge app all it does is read an inbox.json file and an outbox.json file

[near parcel]

I would rather that not be a thing at all. Too many security/privacy considerations to be worth it imo

[warm canopy]

As in what?

If you are filtering the data server in between

[near parcel]

It's essentially a reverse proxy into a network. If you can connect to an arbitrary network server, you can also connect to anything that's exposed in the LAN as well, or any other process on localhost

[warm canopy]

The app doesnt open any inbound ports etc

Mods cant tell the app where to connect either

Unless you are referring to how the devs would implement it

[near parcel]

The mod has to be able to, and that runs locally on the server process. If the mod can connect to an arbitrary 3rd party server, it can open a connection to anything visible by the computer running the mod (LAN/local processes)

The mod can't work as a server for your central DB because it would be behind a NAT pretty much always

[warm canopy]

Thatd be like peer to peer though

[near parcel]

The only option would be for the DB to be the normal backend, but you would only get a key-value store at best as the devs obviously won't allow you to run arbitrary code on their server, and good luck managing which mod should access what data with a single DB server

[near parcel]

If you want p2p connections, you can use the normal server as the DB, you don't need to connect to a remote host (and you would have to, since both clients would be behind NAT)

[warm canopy]

Currently trailbridge implementation is a key-value store. Its not ment for large peices of data being shared. Its done like this for security. Im not sure on how the devs could implement a solution, was just throwing the idea out their. It would be a nice-to-have in terms of allowing for native sharing of leaderboards etc

I have seen it successful implemented in games like roblox with data stores etc

I guess one issue is that the main.lua can be viewed by anyone

[near parcel]

What it implements is irrelevant. You need to store data somewhere, and the only options for that are:

• Use a central, 3rd party server: mods need to be able to connect to it, and since it's not known ahead of time mods need to be able to open connections to anything
• Use a central server hosted by the devs: you wouldn't be able to run any code in the DB server, and key management would be a mess since mods don't have IDs to scope keys. It likely could also only be used within the game
• Use p2p, decentralized connections: you aren't gona have a global view of the data, so not much different from each host having their own data (specially since you have no way to syncronize clients, so at best you would just be able to write on clients of the tm server)

[near parcel]

Roblox runs everything on their servers afaik, they don't need to connect to any 3rd party servers. It's option 2 with a ton of infraestructure

[warm canopy]

Could the steam id of a mod be used as a unique identifier

[near parcel]

No, because you can have local mods

[warm canopy]

The way I do it currently is I have an api key. But idk. Yeah 3rd party server not a good idea nor is p2p

[cinder spruce]

one of my first modding projects was just making some sort of economy system in a way, then i realized it was gonna be really annoying because that ecosystem will only be able to mostly only last in the one session, on that one host

if i ever create a campaign where theres a lot of different resources or things to collect a central market could be a really cool thing to do

[scenic echo]

in what way were custom models limited in tm?

[regal bear]

What do you mean?

[scenic echo]

the point where the models break, was it like 32000 triangles? or was it lower or even something else?

[sturdy iris]

wasnt it like the 16 bit max integer?

[scenic echo]

No idea

Yes, thank you

[sturdy iris]

does ModBlock.SetDragAll only affect aerodynamics or also things like grip with the ground?

[formal crane]

Friction has nothing to do with aerodynamics no.

I dont know the underlying systems fully, but I would expect it to affect movement in water and maybe snow!

[sturdy iris]

hmmm because im looking to maybe have a event for my mod that the ground will be like ice. imma try it i will say if it works

once again getting this and i dont have a clue how to fix it... C:/Program Files (x86)/Steam/steamapps/common/Trailmakers/Trailmakers_Data..\mods\Choas Mod 0.1\main.lua:(101,4-60): cannot convert a userdata to a clr type System.UInt32

[dapper jay]

what is playerId?

it should be a number but it probably isnt

@sturdy iris

[upper niche]

Has anyone tried to make a mod to add actual armor against explosives?
AKA, explosions can't hit stuff behind blocks
To make them less stupidly OP

[sturdy iris]

idk. i used a code snippet https://mods.trailmakers.ludixi.com/snippet/21 and tweaked it. but the base version already doesnt work

[dapper jay]

can you show how you are calling Nofriction?

[dapper jay]

Nofriction gets called with a UICallbackData

not just a number that represent's the player's id

so youd have to do

function Nofriction(data)
    local structure = tm.players.OccuipiedStructure(data.playerId)
    --blah blah
end

[sturdy iris]

ah oke thank you! it now works indeed

[upper niche]

^

[sturdy iris]

im not sure but it would be impressive af. not sure if its possible tho

[upper niche]

aight

[dapper jay]

cant edit the explosion code so its impossible

[sturdy iris]

i mean you can try to make it with raycasts and a alot of them

[dapper jay]

make what?

your own explosions?

[sturdy iris]

well you could maybe use raycasts to see if the explosion is within line of sight and cause an explosion at the enemy vehicle ig

[dapper jay]

i dont understand how that would solve anything?

that would still just use the games's own explosions(which we want to replace)

[radiant lion]

I guess you could spawn a bunch of tiny explosions at the end of the rays, but it doesn't seem neat at all

[scenic echo]

This would be cool for like a modded gun

[elfin yarrow]

curious but would it be possible for the raycast to pierce the player build but still produce an explosion on every point of contact? (even inside the target)

[scenic echo]

Not really, the raycast on gives the point where it hit something but you could calculate it's direction and spawn a few more explosions in front of where it hit

[elfin yarrow]

that's probably good enough

[sturdy iris]

i mean you could make a kinda "timed" fuze just explode it a bit further down the raycast

[scenic echo]

Do you want to see modded bullets?

[sturdy iris]

i mean i could try to make em or we

[topaz arrow]

They were made once already, tho afaik without any special properties like penetration
https://discord.com/channels/296562030624899072/1338940992551649405

[scenic echo]

I made a mod that has custom bullets https://steamcommunity.com/sharedfiles/filedetails/?id=3427741362

Now, with the new api i should try remaking it

[dapper jay]

Whats different in the new api

[elfin yarrow]

stuff

[dapper jay]

wow thats crazy

[scenic echo]

Stuff, i know you can now get the name of a player, you can read chat messages and send chat messages, you can check the drag of blocks and set it, coloring now can color every block, there is new ui that makes big text in the middle of screen appear and other stuff i dont remember

[dapper jay]

i see

[paper bone]

You could get the names of the players before too, but now you can get a unique id for each player

[narrow acorn]

always wanted this

[scenic echo]

Yeah? I did not know

[narrow acorn]

tysm

[scenic echo]

Uhh, i did not test it in 2.2, it might be broken or not, try it and see

[narrow acorn]

doesnt have sound in 2.2 at least

[scenic echo]

Ye, never added any

[narrow acorn]

ye oke

and i dont know what current keybind is suposed to do doesnt do anything in 2.2 it seems

o nvm

[scenic echo]

Is there any sound that sounds like a gun? Also is playing sounds every tick a good idea?

[tribal gate]

Does anyone know if there is a way to check whether or not a raycast hit a ModBlock without going through every block.

[dapper jay]

no :)

[tribal gate]

No as in you don’t know or it isn’t possible

[dapper jay]

not possible

[tribal gate]

Is is possible to check if it hit terrain instead then since that would also be less laggy

[dapper jay]

also no

[sturdy iris]

Depending on the hit function you use it just gives the world position of what you just hit

You have the options:
Didhit > boolean
Gethitnormal > no idea what that does
Gethitposition > modvector3
Gethitdistance > float
Tostring > no idea what that does

[radiant lion]

The normal is basically a vector perpendicular to the surface.
To string will make it into a string, not sure how it's formatted, but it's likely a combination of the other datas

[paper bone]

To string will always return: "Trailmakers.Mods.Api.Proxies.ModRaycastHit"

[dapper jay]

that doesnt sound very useful

[near parcel]

it's likely the default implementation

[topaz arrow]

Wait, chat censoring mod is possible now?

[warm canopy]

Can't edit existing messages

[scenic echo]

No, well kind of, you could ban the person who sent the message and send a big wall of spaces to cover the chat box and swear word

Can you cancel the message?

[warm canopy]

Nope

Making something like this might be a good idea

[dapper jay]

has anyone tried putting ascii art in chat

[scenic echo]

That sounds fun, but the chat box is a different lenght depending on resolution so if you make something for 1080p on 720p a fourth of the art might be not seeble

I'm helping with some mod code to make the train track switching work.

[scenic echo]

What is the difference between ModBlock.GetDragAll() and ModBlock.GetDefaultDragAll()?

[radiant lion]

Current Vs default drag

[formal crane]

Default refer to the "vanilla" values. As in unchanged. Just for reference so you can revert them or do calculations based on them or whatever

[radiant lion]

@scenic echo here's what i use to store data, there aren't many comments, but the most important functions are the encode/decode ones, they want the modBlock, start bit (1-81) and some other parameters depending on what you are storing

[scenic echo]

Thanks!

[scenic echo]

I found something interesting, if you set the health of blocks to 1 for example, from guns they will still take the same damage but from collisions they act like they have 1 health

[formal crane]

set health is generally just cursed at the moment, hope to have a fix in 2.3 🙂

[scenic echo]

i was hoping for it to be fixed this patch, i guess i have to be patient

[formal crane]

It is in the backlog of coming changes, just been a lot of things in works lately 🙂

[latent pine]

can tm mods have header files or does everything have to be included in the main?

[formal crane]

You can make a header.lua file. Include that in the main and then that include everything you want lol

[latent pine]

ah nice

that should clean up my structure quite a bit

[near parcel]

if you want declarations only, you can use ---@meta on the declarations file and the LSP will pick it up. If you want actual implementations you can call, you need to use tm.os.DoFile()

[dapper jay]

someone should make a mod that lets me tell chatgpt to generate me an awesome sportscar only for it to be a brick

[latent pine]

is making a new label the only way to have multiple lines in a ui element? using \n or \r\n seems to get ignored (including the text after it)

[scenic echo]

From what i know, yes

[latent pine]

would be nice to be able to have text blocks that are multiple lines, adding seperate labels leaves quite a bit of whitespace between them

[radiant lion]

Iirc it's not that it gets ignored, but there is a little box around the first line and all the text outside it isn't rendered

You can see this if you scale the text, top and bottom will be cropped

[latent pine]

so if I make the text very small it would fit

[sturdy iris]

i mean you could use a random list of BP's and choose one and spawn one i guess and update the mod every once in a while

[dapper jay]

we can do better than that

world's first llm written in lua

[scenic echo]

Big brain time

[elfin yarrow]

random inquiry, if i don't call ui everytime a new player joins, does it make the ui host-only?

[fallow fox]

yes (I think so at least)

[dapper jay]

you can check if the player id is 0 to make it host only

[warm canopy]

Player id is 0 btw for the host

[latent pine]

yeah they're 1 lower than the in-game list shows

lua is one of the only languages where indexes start at 1 instead of 0 so you actually have to account for it lol

[sturdy iris]

i set up a github for my chaos mod so i can work on the move. but i get all these errors. i did set up the library's and workspaces correctly but why do i still get these?

[dapper jay]

holy shit

[latent pine]

are the playerid's from tm.players.GetPlayerProfileId(playerId) hex numbers or alphanumeric?

[dapper jay]

i assume it returns the steamid? which is just a number

[sturdy iris]

it returns a string

[latent pine]

yes i know that but from looking at it it looks like a hex value

602812b96f7bff6f59ceda4c
this is mine for example

[sturdy iris]

i believe thats the TM player code

[latent pine]

it is, but i wanna know if it is hex characters only instead of just some string

[formal crane]

It is just a sequence of random chars using hex that represents a unique backend ID

[latent pine]

yes thanks

that makes filtering a bit easier

[formal crane]

Filtering in what context/way?

[latent pine]

i'm adding a blacklist function to my mod so i want to store player id's along with their username

need to grab them from a file and filter out what is an id and what is a name

[near parcel]

Just store it as csv/json

[latent pine]

yeah that's what I'm gonna do lol

[warm canopy]

I still wish for steamid since that player profile id can be reset

[latent pine]

honestly doubt most people would put in the effort

[smoky sierra]

can somone help me with settinga thumbnail for a workshop upload

ive downloaded steamCMD and have everything set up but its returning with Preparing update...ERROR! Failed to update workshop item (File Not Found).

ive checked the file is the right vdf type the loacation of the image file is correct

[warm canopy]

Put a .png named Preview in your mods folder

Then upload the mod ingame

[latent pine]

that's a lot easier than for blueprints lol

[smoky sierra]

its a map im uploading

[smoky sierra]

what will this do

[smoky sierra]

wdym

[latent pine]

for blueprints you have to change the image through the steam api

not that hard but it is annoying

[smoky sierra]

wait i think im doing it that way

how do you do it for a mod

[latent pine]

just like this

apparently

[smoky sierra]

it says its missing a lua file

wait he mightve meant in the map's folder

[near parcel]

you need to export the map as a mod first, and modify the exported mod

[hexed hawk]

i nees assistanewith 2 things, the keys between s+f an x+v have stoppe working, unrelate, trailmappers wont let me edit any of my maps, or ccreate new ones

the main issue is the trailmappers thing

[sturdy iris]

Is it your keyboard? If so just get a new keyboard

[hexed hawk]

laptop

[sturdy iris]

I mean you could change your keyboard of your laptop yourself for like 20 bucks or send it to a repair shop for like 30-40 and you can always use an external keyboard on your laptop

[hexed hawk]

i have $2

[regal bear]

Do you mean the keys don't work in Trailmappers only? Or don't work in any app on Windows?

[ivory agate]

You can also work with the png the blueprint is stored in but ue I suppose the steam api is a lot simpler lol

[latent pine]

steam api also doesn't risk corrupting the blueprint

[hoary skiff]

ADD TO XBOX

[latent pine]

ask Microsoft not us

[hexed hawk]

its like trailmakers disables the keys, they work anytime im not playing TM, any other game i don't have issues

[regal bear]

This is the modding channel. I suggest you post your keys problem in #bug-reports

[hexed hawk]

i was trying to explain the spelling issues, anyways, i was here cause i was asking about the trailmappers thing

[elfin yarrow]

what's a modvector3

[regal bear]

Probs better to ask here ->#1226065444364877835

[regal bear]

it's data in the form of a vector3

[elfin yarrow]

interesting

i was hoping to just slap a number for wind speed and wind heading but this seems a little bit trickier than i expected

[hexed hawk]

huh, i didnt know that existed, thanks

[cinder spruce]

vectors are used in the wind speed to easily input both direction and magnitude (wind speed) at the same time

if you want to quickly add something you can just do

tm.vector3.forward() * windspeed

you can change forward to any of the built in directional vectors in tm.vector3 like forward/back, left/right, or even up/down if you want lol

[elfin yarrow]

hold up, i'm asking chatgpt on how any of this stuff works lol

[cinder spruce]

im here to help too

vectors are used a lot everywhere, they should honestly be taught in schools a lot earlier tbh

in the context of tm modding they're used for representing positions like xyz coordinates, directions like in the wind speed, scale for objects, and tons of other things

[elfin yarrow]

this is not something bothering anyone over

[cinder spruce]

no no worries ill gladly explain anything
im pretty bored right now

also i love trying to teach stuff it helps me understand the topic more

[elfin yarrow]

also i have absolutely no coding experience (except like 5m of java which i do not remember at all)

ok so the code is basically the ComplexityMod code but i edited it a bunch
context: chatgpt is trying to get me to log the defaultValue parameter on the UIText's
my goal rn is to have 3 input boxes (windX, windY, and windZ) and then combine them into one vector3 before feeding that into the SetGlobalWind
the commented out ones are unnecessary at the moment according to the clanker itself

i hope that's at least somewhat legible

[cinder spruce]

alright so immedietly the first thing i notice is your parameters on the mulitple set wind functions

there is this neat little thing called ui callbacks. it is data that gets sent to the function as a single parameter, so instead of having playerid, id, value, data in the function, you can replace it all with just one parameter callback

you can use this callback in the function to get all that information by using callback.value, callback.playerId, or callback.id

something like this

[elfin yarrow]

i did not know that, holy that's a lot simpler than i thought

[cinder spruce]

chatgpt doesn't know anything about the modding api so it isn't quite helpful

[elfin yarrow]

on an unrelated note, does the code placement matter? like does stuff change if i put a function above something else?

compared to below

[cinder spruce]

i believe it does
the function should be defined before you add it to UI

although your add ui function is defined before the others, it is actually called later in the onPlayerJoined function (i assume) which is fine

[elfin yarrow]

neat

[elfin yarrow]

how do i actually use a vector? i want to put it into the tm.os.log for now but i'll use it to set wind later

[cinder spruce]

i think i see a better approach for this

you can just create a variable at the top that is the vector, instead of the x y z components of them
have a local windVector = tm.vector3.Create() at the top and remove the old variables

for each of the functions, you can set the individual x y z components by doing

windVector.x = callback.value
windVector.y = callback.value
windVector.z = callback.value

this way, you can completely remove the createWindVector function and ui
instead you can do it in the applyWindVector() through something like this

[elfin yarrow]

alright

it gives a invoke ui callback error everytime i type anything into the UIText, also fails to invoke the onPlayerJoined function, no clue why

[cinder spruce]

maybe change it so tm.vector3.Create() is capitalized

also a good idea to check the logs found in the mod folder to get more info

might also not be a bad idea to fix the weird indenting

[regal bear]

You can log a vector3 directly using the tostring() function:

tm.os.Log("myV3: "..tostring(myV3))```

[elfin yarrow]

ok

[elfin yarrow]

the errors in the logs are "failed to invoke ui callback" and "cannot convert a string to a clr type System.Single"

[latent pine]

they were given some attention in the standard maths program at my high school but linear algebra definitely deserves more attention in secondary education

if anything more about (standard) vectors and a little bit of matrices, they're used in basically any higher level education related to physics or math

[regal bear]

The callback.value from a text field is a string. You need it to be a number. Put tonumber() around the callback.value. eg
windVector.x = tonumber(callback.value)

[sturdy iris]

this is what i did. (from my github repo im working on)

[elfin yarrow]

that actually worked, though applyWindVector gives an error "cannot access field SetGlobalWind of user data<Trailmakers.Mods.Api.ModApiPhysics>"

[elfin yarrow]

yeah i've already seen

[formal crane]

It is not tm.physics but tm.world

tm.world.SetGlobalWind(ModVector3)

[elfin yarrow]

guh...

it actually works

[sturdy iris]

tip dont set the wind speed to a million and look at the map

[elfin yarrow]

i am aware :

[elfin yarrow]

how do i like "refresh" the UI elements? i want the numbers in the in-game mod menu to show windVector.x/y/z numbers when the wind vector is applied but calling addUiForPlayer inside the applyWindVector doesn't seem to do anything

[latent pine]

you can either remove specific ui labels or clear the entire ui and add everything you need back

[elfin yarrow]

[formal crane]

Call

function tm.playerUI.SetUIValue( playerId , id , value )

When you need to update it.

You can do it every

function update()
-- get wind speed
-- make it into string or whatever
-- call tm.player.UI.SetUIValue() for your player and the specific UI id
end

[elfin yarrow]

ah, that seems less clunky so i'll (try to) do that

[latent pine]

oh yeah I forgor about those

[scenic echo]

That's how i did it at the beginning and it was a nightmare, sometimes it just didn't work

[near parcel]

iirc clearing/recreating the entire ui was a expensive operation as it freed the entire context and had to initialize it again, you shouldn't be doing it on each update

[elfin yarrow]

i didn't take a picture but it worked perfectly trust

[latent pine]

if only you could use newline characters in strings without it not rendering the other lines 😔

[latent pine]

are there any restrictions for adding images to tm.playerUI.AddSubtleMessageForPlayer()?
currently using a 256x256 .png, both adding it to data_static or the main folder doesn't seem to work

[mint grove]

I beg can someone help me on this https://discord.com/channels/296562030624899072/1451096990862807112

[near parcel]

are you loading the texture?

[latent pine]

whuh

how do i do that? can't find anything about it in the docs

is it tm.physics.AddTexture(filename, resourceName)?

[near parcel]

yes, the docs should tell you

[latent pine]

hmmm
i think i did something wrong

[dapper jay]

hey gpt can you help me with this thing youve never been trained on

[elfin yarrow]

ngl i should've just sent the documentation with the prompt, would've helped a lot

[latent pine]

fixed it btw
while ago but i went to do other things

[mint grove]

I need help so badly on this please someone

[mint grove]

Please

I need this

[smoky sierra]

if somone could help me id really appreciate it my trailmappers crashes every single time i try go into a map i have tried everything i know like verifying game files reinstalling clearing old saves so i dont think there could be anything corrupt but when i try go into a map after a few seconds on the loading screen it freezes forever

[smoky sierra]

please any possible solutions

[elfin yarrow]

curious question, is there a way to make math.random lean towards one end of the range more than the other?

[latent pine]

easiest way is probably using something like a sqrt

[elfin yarrow]

what's a sqrt

[latent pine]

square root

[elfin yarrow]

oh no, math

[latent pine]

this makes it lean more towards 1

you can play around with functions in geogebra or desmos until you get something with the distribution you like

[latent pine]

what's your range and what way do you want it to lean?

[elfin yarrow]

i currently have -25 to 25 but i want something like -100 to 100 with a lean at 0

[latent pine]

maybe lua had a normally distributed function lemme check

https://stackoverflow.com/questions/59811630/normal-distribution-curve-and-random-number-in-lua
normal distribution approximation

you can take the same formula but with -100 and 100 instead

[elfin yarrow]

i'm not exactly sure how to use that but i think i can figure it out

[latent pine]

function norm()
   local x 
   repeat
      x = math.ceil(math.log(1/math.random())^.5*math.cos(math.pi*math.random())*30)
   until x >= -100 and x <= 100
   return x
end

this will probably work

you can change the *30 to change the standard deviation if my interpretation is correct, lower values means values are closer to 0 on average and higher further away

@elfin yarrow does it need to be an integer?

[elfin yarrow]

i got it, thanks

[latent pine]

if it doesn't need to be an in you can leave out the math.ceil()

[latent pine]

no problem

[mint grove]

Did you change your device?

[smoky sierra]

nope i was literally on trailmappers yesterday

[latent pine]

wth is this 😭

i'm trying to include a header file again since i really want the structure that gives me but i keep getting errors

i have a file called header.lua in the same folder as main.lua, and neither require("header.lua"), DoFile("header.lua") nor tm.os.DoFile("header.lua") seem to work

same if i just use "header" instead of "header.lua"

[near parcel]

submodules are searched in the static_data folder, and you don't have to specify the extension to tm.os.DoFile

[latent pine]

i get the same error when it's in data_static

[near parcel]

post the code and error

[latent pine]

if i do

require("data_static/header.lua")

or

require("header.lua")

i get this error code
C:/Program Files (x86)/Steam/steamapps/common/Trailmakers/Trailmakers_Data\..\mods\terminalMod2\main.lua:(1,7-33): attempt to call a nil value

[near parcel]

don't include the data_static path, and use tm.os.DoFile

tm.os.DoFile("header")

[latent pine]

ah that worked

thanks

[warm canopy]

Yeah dont put the file ending in the DoFile

I've added a video showing the rail switching and signal system that is being implemented into samjr01's map:

[mint grove]

I can't get my obj to export with textures

Wait how can I ad my texture to my obj in trailmappers

[scenic echo]

here

[dapper jay]

you load the texture and then spawn your object with your mesh and texture

[mint grove]

Ohhb

Ok 5y

Ty ty

[regal bear]

You can select your texture after you've placed the object too.

Also you can drag a texture from the custom objects bar onto an object in the 3d window.

[mint grove]

Ohhb that's why their also on the bar

[scenic echo]

@latent pine in your command mod you should add a rules and a setrules command. I think this would be great for easily explaning stuff to new people who have joined. Also a command that allows you to set commands that run when someone joins would be also useful

[latent pine]

I'll be back home Monday evening so I can probably work on it then. you'll probably have to wait a bit since I'm planning on restructuring the mod and possibly changing the ui 😆

[scenic echo]

yeah, no problem. Those ideas just appeared in my head and i thought it would be cool to have them in your command mod

[latent pine]

they're good ideas :p

[tight crag]

does anybody know why my missile turns my plane (custom Missile mod)

[latent pine]

you should mess around with the targeting settings a bit iirc
