alright lemme try that
boreal skiff
You'll also have to set the grabability to drag (iirc)
silk narwhal
You'll also have to set the grabability to drag (iirc)
Grabability() is a method of the player class, not a variable?
i think?
boreal skiff
Yeah, You have to hook it
Fisobs might have something that takes care of it for you
silk narwhal
ooh i see
yeah fisobs has grabability stuff in the properties class
oh yeah, it worked! i was able to just change it in the properties class and now the slugcat grabs with both hands
silk narwhal
@boreal skiff am i applying the force correctly to the crate? ive got the code (self is the player)
var phys = RoomPhysics.Get(self.room);
if (phys.TryGetObject(self.grasps[0].grabbedChunk.owner, out var obj))
{
var rb2d = obj.GetComponent<Rigidbody2D>();
rb2d.AddForce(force * self.input[0].analogueDir);
}
``` this code doesn't seem to make the crate move Looks good to me. Try increasing the force you apply
silk narwhal
Looks good to me. Try increasing the force you apply
Like multiplying it by 3 or somethin?
boreal skiff
Yeah, or 10000
boreal skiff
Just to make sure that there's actually something going on here. If you apply a crazy amount of force and it doesn't move, then something else is going wrong
silk narwhal
Ah i see
boreal skiff
Oh, wait, I see. If you aren't using a controller, analogueDir is zero
boreal skiff
I'm also not sure this is the way you should go about calculating the force to apply. Shouldn't you calculate the direction from the grabbed point to the player's head, then apply the force there? (if the player is greater than a certain distance away, that is)
silk narwhal
maybe? im not too sure, this is the first time ive tried making push pull dynamics
ill try that though, id just assumed that id need like the player's directional input to see if they were pushing against it or pulling it
boreal skiff
If the player can collide with the box, you shouldn't need any custom pushing code
silk narwhal
oh, fair point lmao
boreal skiff
Here's the dragging logic from the vanilla game
If the player's head (base.mainBodyChunk) is more than 5 + grabbedChunk.rad pixels away, then it applies a force to both proportional to the separation between them
silk narwhal
ooh i see, alright thx!
if its alright, could i ask one last question @boreal skiff?
boreal skiff
Go ahead!
silk narwhal
alright, for the grabber body chunk, when grabbing the crate i want it to then follow its position relative to the crate until the player stops grabbing it
ive got code for an offset creator that'll make and set the grabber chunk's position to the offset of the crate, but when it runs it not only keeps it relative to the position of the crate but flips it in both x and y every time it runs
(self.grasps[0].grabbedChunk.owner as Crate).grabberPos = (self.grasps[0].grabbedChunk.owner as Crate).firstChunk.pos + offset;
do you know what's causing it?
or actually, do you know of a better way to go about this?
i got a video to show whats going on, but i just realized when the square rotates the grabber chunk doesnt rotate with it, i might need to come up with something else to keep it relative to the crate lmao
boreal skiff
alright, for the grabber body chunk, when grabbing the crate i want it to then f...
I'm not sure what this code is supposed to do. Right now, it's the same as writing:```cs
grabPos = 2 * chunkPos - grabPos;
oh shoot lmao
uhh
do you know how i could make a point always stay the same distance/angle from another point?
boreal skiff
If point is a point that you want to stay a fixed distance away from another point, anchor:
point = (point - anchor).normalized * distance + anchor;
ah i see, alright thanks!
silk narwhal
i mightve implemented it incorrectly lmao
old sphinx
elongated
brazen ravine
I'd say
silk narwhal
hmm
old sphinx
are you simulating it with like a unity fluid simulation?
nah i just add velocity to the point if they are under water
silk narwhal
ah i see
old sphinx
i can jump on the cubes like platform, pretty cool
silk narwhal
oo make like a raft lmao
does water in the game react to the bodyChunk itself or it's texture?
old sphinx
water is a updateable object that pushes all bodychunk in the room
silk narwhal
hmm
if its just reacting to the bodyChunk that's weird that its acting like that then
maybe its like being caused by the added velocity?
silk narwhal
ocean world...
maybe we could make like a river of magma you have to float across lmao
old sphinx
magma? does ur map have those
silk narwhal
in the lowest region Thermal Wastes ye (and The Forge would have molten metal), but that's quite some time before we get to that lmao
silk narwhal
grab code soon enough will be done (need to tweak it a bit, but the dragging is done as well)
old sphinx
oh nice
silk narwhal
Also, ive found a crash that occurs when loading into arena, exiting to main menu, and loading in again. It seems that the fake unity scene isnt deleted when a player exits from the arena, which crashes due to trying to make another arena with the same name (I think). It's not game breaking or anything since its just arena and easily avoidable, but we'll need to prolly find what's called when the arena's closed out so we can delete the scene when the player does so
old sphinx
i wounder is this some kind of body chunk pushing each other thing
silk narwhal
i wounder is this some kind of body chunk pushing each other thing

can u recreate this?
mine works fine tho
silk narwhal
Wait actually?
Uhh im out sightseeing rn (im on vacation for the week), but ill be back in like 6 - 7 hours and see if i can get a video
silk narwhal
Hmm
silk narwhal
Maybe it was just going back to arena menu? Not sure
old sphinx
is it like watching birds and stuff
silk narwhal
Nah we're going to some mountain ranges to go do a little hiking to some vistas, and then to some popular spots around the town here
silk narwhal
yeah
Ah wait i just watched the full video; try doing it with the same room both times
silk narwhal
hmm, ok ill have to test that in a bit
silk narwhal
ok now im not getting the error... im going insane 
silk narwhal
wait no im not going insane!!!
the crash i believe is related to the grab code somehow and the scene, its like after i die and respawn in arena if i try to grab again then the game freezes 
old sphinx
any error logs?
silk narwhal
Uhh
One moment ill go see if i can get one
so it seems ive got like two of them when this happens:
one relating to a reference being null when ReleaseObject is called (which i dont hook, so worried ), and the next is about a Scene with a name already existing
boreal skiff
Hold on, why do I see async code there?
silk narwhal
Hold on, why do I see async code there?
wait whats async code
boreal skiff
wait whats async code <:rivworried:1026397140517388338>
this
Generally, it's a huge no-go in Unity since it sneakily causes things to be called from different threads, crashing when you try to next interact with Unity
If you inherit from PlayerCarryableItem, you can use the Forbid method to stop the player from grabbing it for a bit. If that's not an option, you can implement a similar system yourself (set an int variable of the PhysicalObject that counts down each tick)
silk narwhal
oooooh i see, shoot i forgot i did hook release object 
i guess it autogenerated the async though, since i just pressed tab twice when doing it, but ill try out the inheritance from PlayerCarryableItem with Forbid, thx!!
boreal skiff
Np
Just out of curiosity, where'd you get the await Task.Delay(200); code?
I've seen people try to use it in Rain World mods after ChatGPT told them to. Or stack overflow, actually
silk narwhal
Just out of curiosity, where'd you get the `await Task.Delay(200);` code?
Ah, i looked up how to make a method wait in a program with C#, and I first found Thread.Sleep (until i figured out in game that stopped everything ), then found Task.Delay from the Microsoft docs on C# when searching if i could do it for just one method
boreal skiff
That makes sense
silk narwhal
I dont trust that ChatGPT could ever write for rain world lmao, and stack overflow scares me just a little bit
silk narwhal
ah dang, im sorry to hear that
silk narwhal
@old sphinx does the object already detect slopes?
old sphinx
yup
silk narwhal
Ah lemme add that to finished on the trello then lmao
Im wondering, after the object to object, player grabbing, and some framework stuff like making this a dependency you can put on any object, do you think we should release a beta version of this while we figure out the ai problem?
old sphinx
maybe? i dont really see the use of a bunch of random squares/rectangles
silk narwhal
we can change the boxcollider to be any shape tho right?
I dunno maybe people might wanna test making objects with it, not sure though
old sphinx
errrrr, the collision slime gave me only works on rectangles, i might find a way to deal with polygons
silk narwhal
I think(?) we could just change the unity type (i forgor what the name of the polygon collider was called)
Im assuming we could replace the code that instantiates the boxcollider and its properties with a polygoncollider and it'd work? I think? (I hope?)
old sphinx
I mean like a box collider collision resolve is different from a polygon
silk narwhal
Oooh i see
Hmm
I had assumed it'd work if the code you did for the box to collide when rotated worked
We'll have to figure somethin out for that then though
sweet crest
I want to know. Have you also tested circles too?
old sphinx
Moving circles?
sweet crest
I mean... we got a physics box that can be tossed and moved around. What about a circle? Or really any shape? Like a triangle?
old sphinx
silk narwhal

We can probably do it with the polygon2dcollider, but we might have to implement some custom stuff for bodyChunk to object collision
silk narwhal
The GitHub it's updated now?
Wait updated to what point?

i finally got around to doing this, but still get that same weird error
silk narwhal
on one hand though just got this horrific screen shot 
old sphinx
your slug is doing fine
thier are just feeling a bit under the weather
i probably do a pull once i manage to make polygon stuff work as well
silk narwhal
Ah alright, gotcha
I tried messin around with making it a polygonCollider but it was still a square? It was weird
old sphinx
I tried messin around with making it a polygonCollider but it was still a square...
did u give them points
silk narwhal
did u give them points
Yeah like the array that draws the lines right?
old sphinx
i think those are vertex
silk narwhal
Ah i thought it drew the lines using that
silk narwhal
Well, id say slimecubed has helped us out quite a bit, but yeah having another person could be nice, especially for the ai that we gotta tackle soon enough
brazen ravine
AI? Sounds like pain
silk narwhal
AI? Sounds like pain
So we've heard, apparently its like a problem no one else has been able to fully solve for super slopes and the like? ()
ah shoot srry for ping
brazen ravine
nah you're good
I think at this point you're just needing to make dynamic pathfinding, which yeah noone has figured out how to do with RW creatures
silk narwhal
how hard could it be 
You know, maybe we could try using unity's ai system to make it work? 
brazen ravine
hmm, since you already have a system in place, maybe?
For like getting a RW room as a unity scene
silk narwhal
Yea! I think Bro said the hard part of it was moreso getting the creatures to move with their pathfinding, since they (i think) move by like grabbing terrain with their hands
old sphinx
most AI have perbaked path
old sphinx
You know, maybe we could try using unity's ai system to make it work? <:saintsmi...
idk about that, rw got its own system for everything
silk narwhal
idk about that, rw got its own system for everything
true yeah, i dunno we'll have to figure out how to make the pathfinding recognize the unity stuff somehow
silk narwhal
Since we're using unity for the collision can't we also use Unity Joints to connect the colliders together as well?
boreal skiff
You definitely could
silk narwhal

Maybe you could have them avoid boxes altogether?
Check out AImap.TileAccessibleToCreature. I would hook this, then check if the cell is touching a crate. If so, return false. Otherwise, return orig

Check out `AImap.TileAccessibl...
ill check it out, thx! I gotta finish up the grab code, for some reason its being very resistant to me increasing the value the slugcat pulls at 
(i think it like pulls it past the slugcat which then registers as pulling the other direction which leads to like a springing motion)
once thats done though and the polygon stuff is done, i might try something silly with the unity joints and make rw crane game
silk narwhal
once thats done though and the polygon stuff is done, i might try something sill...
Ah wait i lied we gotta make this system into something you can like plug onto an object before that rather than its own object
boreal skiff
What's the end goal with these? Are they gonna be objects that region authors can add to their rooms?
silk narwhal

Yep! Stuff like movable geometry, operational machines, and the like for much more possibilities with gameplay and maybe environmental puzzles (we plan to make a region or more with them as well)
silk narwhal

I do wanna release it as a dependency thing tho so that authors can make their own custom objects with it as well
sweet crest
Is a lot of that stuff going to be placeable with dev tools?
Also is a custom object system going to be implemented for simplicity (json) or is this more a code framework to add in more objects with c# code?
silk narwhal

i think all the stuff will be placeable via dev tools, and at least right now this is being built as like a framework to add in these types of objects easily (like you'd attach it to a bodyChunk of your code), but i did have the idea of making a build-your-own object thingy that you could attach together different shapes and joints to make an object, not sure how hard that would be tho
brazen ravine
Super Mario Slugcat Maker!
silk narwhal
@old sphinx after i get this moss water done would you want me to help you out with the object to object/polygon code?
kind egret
Huh, I've been messing around with this stuff myself and it seems pretty cool
Not adding rotation with my implementation but still very cool stuff
the fact that from what I've looked around ya'll added rotation is very commendable
kind egret
ya'll are using unity rigidbodies or smth?
boreal skiff
Yup. Cactus has it recreate the level as a Unity collider, then adds a rigidbody with a square collider for each box
It's pretty neat, it uses PhysicsScene2D to sync the updates with the game
kind egret
very cool stuff
My approach is just making a UpdatableAndDeletable, and using hooks into bodychunkcollision and tile detection to get some basic rectangle. It does not work for rotations at all, but it works for the purpose of being a gimmick in like one or two regions in the mod I'm working on lmao
silk narwhal
yo no way, i didnt think this forum would get used anymore
Ive been takin a break from it cuz of some irl stuffs but imma be hopefully gettin back to workin on it soon, but i gotta say youve made some quite cool stuff! I still havent gotten the player movement update stuff down totally, but i think(?) from the videos youve posted it looks like you cleared that as well, lookin quite cool!
I think the scariest thing is gonna be trying to implement creature support with their ai... cuz afaik itd need like a whole rewrite of their ai for it or somethin 
kind egret
I think the scariest thing is gonna be trying to implement creature support with...
In theory you could have some way to update their AI maps every few frames. Though then they won't realize that the platforms move lmao. I do wish you luck on that, as it's out of the scope of my implementation lmao
I'm not even sure if I can think of a game where AI can pathfind in a way where it realizes moving platforms move
silk narwhal
I'm not even sure if I can think of a game where AI can pathfind in a way where ...
yeah, it seems like itd need some big rewrite
maybe with having a new pathfinding system take over the old one when in a room with a moving object, but still would need a lot 
kind egret
for sure
In my case I don't need it at all as there will never be creatures in the rooms where moving platforms are in my case lmao.
silk narwhal
ah fair enough, i wanna make mine as a library for others to use to make custom object stuff so im hopin i can figure somethin out for it
