How would you go about moving particles in a particle system after they have been emitted

#

without movinf the whole system

#

You might also want to consider whether or not using particles is the right choice here, depending on how much you will want to manipulate them

This worked well enough and i dont have to make two silly scripts for one functionality xD is nice

#

Is there a "clean" way if there's water everywhere at the bottom of my map to have an infinitely large respawn trigger at the bottom (where there water is), or should I just make a very large trigger and place it there?

#

I would also go with a trigger.
Y position can change if you have different heights terrain.

#

eg you can also slope a trigger angled, you can't slope positions easily. Ofc depends on your level/use case Y pos check should be sufficient

glad dew
rigid island
#

Yeah I mean that works but Imo a trigger is also easier to see clearly visually in the scene

#

there is no second guessing on numbers etc

glad dew
#

Also, the preference depends if you want this for an emergency catch all respawn for when a character falls through the world or if it's for intended obstacles with death pits etc that player might fall into during regular play.

rigid island
#

if its flat, number should be easy, if you have many variations in height, triggers are better

glad dew
rigid island
#

I know but now thats already more work than a trigger 😆

glad dew
#

Well, better be safe than sorry when it comes to falling through the world due to a hole in colliders somewhere thinksmart

rigid island
#

its not like the cartoons? if you fall into a hole you just end up on the otherside of the planet UnityChanLOL

lean sail
#

A component on each object that checks your position, which may need to change between scenes, is a lot more setup than a large trigger

glad dew
#

Not really, you only need to add like 2 lines to your player controller to check the current height and call respawn from there instead of checking if you collided with a respawn trigger from OnTriggerEnter.

#

A simple component that contains just a public float KillFloorHeight. Ain't exactly computer science.

#

It's not "bad hardcoding" to want a plane that's always infinite as a catchall. What if something clips into the ground and gets yeeted far beyond the bounds of your trigger volume.

It's probably for use cases where you don't want the values to be immediately updated while you are still typing, eg when value changes it triggers some side effects that are undesirable to trigger on every key stroke.

That does make the most sense, though even knowing about that attribute I'd probably implement that functionality myself

I have a script that returns a Mesh based on (int sides). I'm repeatedly getting the same Mesh from the same sides. Should I just add a dictionary[int, Mesh] and not generate the same Mesh over and over, or would storing them be less convenient?

leaden ice
#

You will also need to manage cleaning up the cached meshes somehow

open plover
#

Nothing else

#

Each mesh would be reused probably like 20 times

leaden ice
open plover
#

Whats the difference?

leaden ice
# open plover Whats the difference?

Technically I believe when setting the mesh there is actually no difference. But when reading the mesh, if you use .mesh it will allocate and create a brand new mesh unique to this one object, with the expectation you plan to modify the mesh and don't want to affect other objects. .sharedMesh allows you to get the original mesh without creating a copy, with the understanding that other objects may be sharing the mesh so changing it may affect many objects.

So I'm trying to compare two colors by thinking each of the r,g,b values as x,y,z and comparing their distance in the 3d world space. The algorithm does generally good, but sometimes two distinct color's distance could be as small as green and light green. What extra check could I add to fix this?

open plover
leaden ice
#

i.e. you want those to be the same?

open plover
#

Neither

leaden ice
#

or do some more complex analysis on the whole HSV set

like "if it's within n hue value but also within m brightness" for example

leaden ice
#

So you want.. what? I'm still not clear on that

open plover

#

and the other way around, they could look pretty same and be distant from each other

#

so what I wanted was an extra check besides the original equation

leaden ice
#

just due to the way eyes work

#

I believe I helped someone solve this a long time ago but one thing you can do is adjust the sensitivity of your distance check based on how far the hue is from green

#

i.e. with a remap function

open plover
#

that makes sense

    {
        Vector3 mousePos = cam.ScreenToWorldPoint(Input.mousePosition);

        var emitParams = new ParticleSystem.EmitParams();
        emitParams.position = mousePos;

        cosmicDustTap.Emit(emitParams, 1);
    }```

for some reason this is making the emit position very high up on the y axis
#

and not on the mouse psotion as it shod be

somber nacelle
jaunty sundial
somber nacelle
#

then it's going to be at the same Z position as the camera, so either way it's going to be too close to the camera so the camera won't be able to render it

jaunty sundial
#

i dont think it would it shod just give the position of the mouse in world space

#

cause thats how it workedbefore

somber nacelle
#

you can think that isn't how it works all you want, but that is how it works

#

if no Z position is specified then it will be the camera's Z position. and naturally that is too close to the camera for it to render

jaunty sundial
#

well i can see the particles so they z position is fine

I'm trying to use a lambda function to get the objects with the lowest rect.x, not the lowest rect.x float value. This is my attempt so far Room room = level.rooms.Min(r => r.rect.x); but its only giving a float

jaunty sundial
#

its just the y position thats off

somber nacelle
#

and have you considered that perhaps the particles you are seeing are the ones that have moved up and away from the starting position of the mouse's X and Y coordinates and the camera's Z coordinate?

just write a for loop then

could also just grab the source from source.dot.net or something and drop it into the project (with some modifications to make it compile)

Hello, I've been working on a problem for most of the day and its got me stumped. I have an NPC that is supposed to complete jobs by moving around the navmesh to given locations and carry out a task at each given location.

In my current setup, I have it moving to the location to pick up an item, then move somewhere else to discard it. The moving part works great, the picking up and discarding not so much.

#

the NPC brain script has a public array containing all of its tasks. The tasks right now are empty game objects placed around the map. It works for pathing. This is where I am struggling. In my design the tasks contain the associated action inside them, so the pickup location has a script attached which has a method to give an item to the NPC. The NPC has a reference to that script through its parent gameobject (the task object), and the NPC calls the method to give itself the item from the task

#

Now that I'm writing it out, this seems rather backwards, but I was hoping someone had a better idea of how I could do this.

I was playing with putting a collider at the task location to trigger the task, however I'm building for a warehouse environment where lots of NPCs doing the same jobs may pass through the collider as they are moving around

cosmic rain
# proven light the NPC brain script has a public array containing all of its tasks. The tasks r...

I have an actions system in a project I'm working on.
The actions are just a list of so's that the character(or a character template) has. I then use goap similar system to generate an actions plan. That part is probably irrelevant to you, but when I create an action within the plan, I provide it all the required info, like the item reference that it needs to pick or an object it needs to interact with, for example. These references are passed to the system from the character sensors. The sensors update every frame(or a few frames) and detect all kinds of objects within some radius around the character. If the detected item is an item container(a physical representation of the item or an inventory in the game world), I add all the items inside to a list of detected items.

proven light
#

If I'm understanding that right, I should essentially be making the equivalent of a pickup button for the AI? Then I just have it be able to see and decide which one to pick up based on what's around it?

#

more specifically, it would be like "your job it to pick up chicken" so it moves to the chicken point and looks for "chicken" in the list of detected items?

cosmic rain
cosmic rain
#

The latter one should work the same way both for ai and player characters.

#

The former one is what replaces the player brain for the npc.

proven light
#

Action decision is going to be handled by an outside source, in this case preprogrammed but in the final form it will also be able to be assigned at runtime

cosmic rain
#

In my project, both the player character and npcs use exactly the same system for action execution.

proven light
#

just executed from a different source (human input vs... NPC whatever) right?

cosmic rain
#

Yes

proven light
#

ok yeah. I essentially have the same. Everything is using the same inventory system, I just need to make the NPC perform the action. Neat

cosmic rain
#

You probably don't want the UI to be a part of the this actions/jobs system at all. It should be part of the player controls.

proven light
#

In this case its exclusively NPCs, so that takes care of itself

#

Well that makes a lot more sense now. Originally it was "Go to chicken and activate the chicken action and do what it tells you", whereas now it will be "Go pick up chicken"

#

I just need to figure out how to attach the action to the location

#

Because right now we have "go chicken, go truck"

scriptable objects sounds like a good approach. I will need to go back and study them again because I am not very familiar with them

#

reading into scriptable objects more, I dont know if I'm misunderstanding but they cant store implementation? only data?

fossil remnant
#

I'm not entirely sure where to look or how to properly word this: I have a scriptable object in it a few serialized classes attached, these are just a lists of the same scriptable object.
I made it so I could just right click and make the object, the idea is that the scriptable object has 4 lists which just say what can be near its 4 sides.
Is it possible when I had an object to the list, it adds the second object to the first objects list?

#

Essentially the lists look like this, in editor I drag and drop in other nodes. I'm wondering if its possible that when I add the prefab node to this one, it adds itself to the other

I dont know how I can attach a custom interact behavior to different objects and still trigger it in the same way for all of them

As you can see from the debug outputs, its not gaining any momentum at all. The rb's mass is set to 54, but even when I set it to 1 it gains as such a low rate that its nearly pointless.

Debug at 1 mass, while sprinting (doubling the incoming velocity):

incomingVelocity: (2.32, 0.00, 5.53) currentGroundAdjustmentVelocity: (0.00, -0.01, 0.00) 


acceleration: 4 desiredVelocity: (2.32, -0.03, 5.53)
Actual Velocity: (0.00, 0.00, 0.00) Current Speed: 0.001421971 Desired Speed: 6.000091

I dont see why you need the rest of the code, I literally am outputting all the variables used. Nothing else in my code modifies velocity on the rigidbody.

leaden ice
#

it gets updated during the physics simulation

#

If you want to do it in a way that is visible and mathematically equivalent you can do this:
rb.velocity += desiredVelocity / rb.mass * Time.fixedDeltaTime;

#

note that desiredVelocity is a confusing name for a force.

The "not supposed to modify velocity" instruction is mostly about setting it to something that doesn't take into account the current velocity at all

#

In addition I thought it would cumulatively add the force the longer the velocity was applied.
This is true both about AddForce and doing velocity += ...

#

For example if you do velocity = Vector3.forward * speed; this completely overwrites the velocity. That's the thing you were warned about

Gotcha that makes sense. I'll look into a bit more.

I'm currently trying to make a small tower defense game, mainly inspired by Bloons, and I'm having trouble making a good way to get the enemies' movement path to work well. All tutorials I've found so far have just placed "checkpoints" and having the enemy move toward the next checkpoint whenever they get close enough to the previous one. This doesn't work for me, both because it can mess up at very high speeds, and because I'm trying to make enemies that split into multiple smaller enemies when killed. When this happens I don't want the smaller enemies to just spawn on top of each other.

Like, if an enemy splits into 2 I want one to spawn slightly forward on the track and one to spawn slightly back, but I can't figure out a good way to accomplish this, at least not with the current way I made the path. Does anyone have any ideas?

I am trying to jump to a time on a timeline, but for some reason when this code runs while the timeline is paused, it evaluates signal emitters in-between the current time and the time it's jumping to (that aren't set to retroactive). How do I avoid this?

As an example, imagine a timeline where this code runs at 10 seconds, there is a signal emitter at 15 seconds, and the marker it is jumping to is at 20 seconds. If the timeline is playing and hits 10 seconds, this code will correctly jump to the marker's time, skipping the signal emitter. If the timeline is paused at exactly 10 seconds, when this code is called to jump to the marker at 20 seconds the signal emitter at 15 seconds will be evaluated. How do I prevent this?

director.Pause();
director.time = markers[markerID].time;
director.Evaluate();
director.Play();

If it's an FBX that just happens to be in a unitypackage file then it's just an FBX and this has nothing to do with Unity. If there's more stuff added to it all of that is Unity-specific and cannot be exported. (You may have luck with the FBX exporter, but that's unlikely to be relevant).
This is a programming channel for Unity. None of your question relates to that, so it's no surprise you're getting a response like this

I have n 2D points in clockwise order, which each connects to the origin and thus they divide the plane in n parts (think a pie chart). Given a target point, what's the easiest way to tell which part it's in/test if it's in a certain part?

quaint rock
#

if its like a pie chart, you should know what angle each starts and ends out

#

can make a direction from the origin and given target point and get its angle

chilly surge
#

Testing angles is kind of annoying though because of wrapping around.

quaint rock
#

modulo to 360 should help with that unless one of pie pieaces goes over the 0 point

#

other way could just be treating each area like a triangle and testing if the point is in any of them

#

i forget that math for checking that manually

#

but you could use like a PolygonCollider2D and its OverlapPoint method

chilly surge
#

Yeah I'd like to do that with pure math.

#

The points can rotate around and the only guarantee I have is that the points are in order. So even after moduloing them, the first point could have an angle of 350 degrees, and the next point could be 7, and checking if an angle is in between or not still seems a bit annoying.

#

I guess one approach is to normalize the angles to a strictly increasing manner, and also normalize the target point's angle to be larger than first point's angle, then comparison could be done without worrying about wrap around.

quaint rock
#

yeah mentioned that first since solving as a trinangle is kind of a pain

Need a bit of analysis. In this video, I'm placing my mouse over a specific part of Earth, and as I zoom, the camera slowly pans over to that location centered around the mouse. What's the math behind this?

#

Could be something like that but the zoom out is something that I'm wondering how it would be able to inverse that behaviour

maiden fractal
# dawn nebula Need a bit of analysis. In this video, I'm placing my mouse over a specific part...

One thing I'm wondering is whether it would simply work by zooming in by moving the camera straight towards the earth and rotating the camera right amount to keep the cursor pointing at the same point on map. To help calculate that rotation, it might be easier to try to figure out the amount you need to rotate the earth to keep the cursor at the same point and just inverse that rotation to get the camera rotation

plucky inlet
#

I am guessing, the target spot the camera is point to is also just a lerp between center of earth or current rotation towards the final spot. Botht he movement and target lock are then animated from 0-100 percent in parallel to give you this smooth bidirectional movement.

soft shard
# placid edge what movement type is good for when I want to add 2 different movement forces to...

If your using rigidbodies, you could use AddForce to add a directional force onto the current velocity, or you could control adding velocity yourself, I do something similar for effects in my game where I have a "move" velocity controlled by player input (in your case, it sounds like it would be controlled by AI logic) and then I can += a "influence" velocity and either drop it over time back to 0, or have something like a debuff set it to 0 when it ends, so it may be something like rb.velocity = move + influence; influence = Vector3.Lerp(...);

placid edge
#

Hmm somethings not adding up for me here

#

the lerp is the distance between the black hole and the object right?

#

and the move is the original movement betwen its current position and its destination?

knotty sun
#

no, lerp is
current = start, end, t
where t = % of difference between start and end expressed as 0-1

placid edge
#

yeah thats what i meant ;v

#

so t at 1 would be a blink?

knotty sun
#

no, t at 1 would return end

placid edge
#

so, yes...

Lerp(a, b, 1) just returns b

I have this "chunk" of integers here, which is a blank canvas for my procedural road script to create road on, so moving one tile up would be done by subtracting 8 from the current tile, and down, would be to add 8 to the current tile.

My question is, now that i am making it detect if it is near the edge of a chunk, how would i do that with the left and right edge? - I did it for the up and down, by checking if the length of the array is longer than current tile + 8 for down, and same with "- 8" for up, but how could i do left side check when it can be all the numbers: "0, 8, 16, 24, 32, 40, 48, and 56"

should i just check if the currentTile incremented with one would be divided by 8 with a remainder of 0 ?? or does that have some issues as well??

wanton cedar
#

i would rather not xD - each of these numbers will be changed, and each of those numbers it will be changed to has properties that i have allready built

leaden ice
#

Or I guess you're asking if the column is 0 or 7?

#

wouldn't it be:

int width = 8;
int height = 8;

int row = index / width;
int col = index % width;
```?
#

then it's just bool onHorizontalEdge = col == 0 || col == height - 1;

#

likewise bool onVerticalEdge = row == 0 || row == width - 1;

simple egret
#

You can convert XY "coordinates" into a single-dimensional index using the formula idx = WIDTH * y + x assuming Y goes down (rows) and X right (columns)

leaden ice
#

yeah that's the reverse calculation:

int index = width * row + col;```
wanton cedar
#

the rest of the row & column navigation is pretty much made by now, so i just wanted to use math for this last little detail. The script will move out procedurally from around the center point, in increments of one row/column at a time. so if i can just with math calculate a list of numbers that would make up the left and right "edge", using the width of the square

Why if I wrap serializable fields with #if UNITY_EDITOR and build I sometimes get an error which says that an scripted object has a different serialization layout?

  1. Why it's sometimes and not always?
  2. During building the game, I thought unity recompiles the scripts and reserialises the assets, if that were true then this error should not appear and they field would be filtered out. 🤔

(As a side note, a single dimensional array where you do your own index conversion is obviously the fastest, but even jagged array is faster than multidimensional array. Not that I would suggest choosing base on performance, the difference between these are negligible in most cases)

not likely to be related to the FBX, no

You need to set this to pivot

if you want to see the real locations of the objects

lime viper

ok , yes the pivot is way off in the distance. but i feel like i can find that in script then translate it over to where the red sphere is on the door.

like find pivot and center in script then move pivot to center and use it for rotate.

Check out StringComparer.Create(), you can pass a culture and a variety of string comparison options (ignore case, ignore symbols, etc.). You could pass an instance of that into your method and use .Compare(s1, s2) to do the string comparison

i'm trying to make snake on this system.
when the object collides with one of the squares, that same square turns on the light to the right colour. red for food, green for head and yellow for the tail.

when the object enters the collision of the square, it changes the colour to the right colour (red, yellow or green), and when the objects exits the square, it changes it back to 0/off/white.

however as visible in the video, it turns on and off the lights at the same moment. causing it to be inconsistent if the light is on or off.

i'm using the following code:

        }

        if (collision.CompareTag("Red"))

wow. Does unity read these inputs as regular HID device or ? serial?

however now that i'm actually making a moving game, i have the above problems

#

okay so the LED matrix is just a simple 2d array. Ok so you only set positions OnTriggerEnter it seems

#

or is there a movement script that updates each motion/ key stroke

sick cove
#

and with OnTriggerExit I reset them

rigid island
#

which object has this trigger though

sick cove
#

there is a movement script. but it doesn't interact with the lights

#

the squares each have their own trigger

rigid island
#

oh

sick cove
#

when someonething with one of the tags collide with those the colour changes to the one with the same tag

#

so i have a 'red' tag, a 'yellow' tag and for the player i have green 'player' tag

#

so i use compareTag for that.

rigid island
#

the same script works on PC ? because using triggers is not something i've seen before with a snake game

sick cove
#

from what i see, it fires both enter and exit at the same time, because both something enters and exits the square.

sick cove
#

let me quickly make a gameplay video from pc

rigid island
#

I feel like thats what might give off result, need to prob see how you move the snake as well , thats very important for accurate detection for physics (triggers)

sick cove
#

for the movement:

i set a vector2. to one of the directions using the buttons in fixed update. and then i lowered the fixed update amount to about 0.25

rigid island
#

I would probably just update the LED matrix every move made. I would not use triggers or physics, esp the 2D representation working fine

#

assuming you are moving this with transforms directly or something ?

sick cove
#

normally yes, this is just a prototype.

sick cove
sick cove
hexed pecan
#

I wouldnt use physics for this at all, some array/2d array would do

rigid island
#

yeah moving too fast that wont give very accurate hit results

sick cove
#

with a mathf.round to make sure it's a full int

rigid island
sick cove
#

i'll just have to figure out how. i'll take a look at it.

#

not to used to coding things like this

rigid island
#

but yeah physics here is overkill and prob more harm than good

rigid island
sick cove
#

is on it's way

#

i don't use the rigidbody and movespeed, which are in the script as something i removed

rigid island
#

yeah rigidbody is the physics component, right now you're teleporting it skipping the physics

#

sometimes it catches up in time though so it does detect

#

you normally let rigidbody move your transform into place, instead of other way around

sick cove
#

the green is always consistent on the screen. it's only the ones that come after that that get confused and randomly decide to be on or of each movement

#

screen = board

rigid island
#

just one of those luck of the draw things lol

sick cove
#

yep.

rigid island
#

guaranteed if you code the leds to match whats already happening in the 2D space you wont have issues

sick cove
#

is there a way to delay either the 'onentertrigger' or 'onexittrigger' ?

rigid island
#

you dont even need triggers

#

You could just signal an event or just tie the LED script into movement

sick cove
#

i'll take a look at both options. thanks a lot

rigid island
#

you already have the positions of yellow, green and red no? you just update them on the led board each movement

#

might have to create mapping function like v2 to your 2d array matrix

sick cove
#

so first check the locations on the grid, and then update the lights

rigid island
#

yeah first you want to make your current movement move on a 2D array board

sick cove
#

i'll have a look at it later tonight. i have to go now. i'mma save all of this

line 40

rigid island

whatever is on line 40 is null then 🤷‍♂️

hasty plinth
#

it is on this line
BlackHoleData[i].x = stageManager.BlackHoles[i].x;

rigid island
#

stageManager or BlackHoles[i] is null

hasty plinth
#

stageManager.BlackHoles[i].x is not the problem

#

BlackHoleData[i].x is null

rigid island
#

x can't be null if its a float

#

prob BlackHoleData or BlackHoleData[i]

somber nacelle
#

presumably there was nothing assigned to that index of the array

hasty plinth
#

yes because I am setting it right now

somber nacelle
#

where

rigid island
#

on/from an unkown/null object prob

hasty plinth
#

ok so give me a sec

#

at the begging of the code i set

public BlackHole[] BlackHoleData;
rigid island
#

is this a private array ? did you actually initialize it

hasty plinth
#

where

[System.Serializable]
    public class BlackHole
    {
        public float x, y;
        public float size;
        public float radius, pull;
    }
#

at the bottom of the script

rigid island
#

alright so whatever is at index i its null and not blackhole

hasty plinth
#

then I do

BlackHoleData = new BlackHole[stageManager.BlackHoles.Length];
        for (int i = 0; i < BlackHoleData.Length; i++)
        {
            BlackHoleData[i].x = stageManager.BlackHoles[i].x;

rigid island
hasty plinth
#

Oh ok then

#

give me a sec

#

I assumed you could see it

hasty plinth
somber nacelle
#

okay well the issue remains the same, you have not actually put an instance of BlackHole into any index of your array, therefore every index contains null

#

same goes for your Obstacles array

rigid island
#

all you need is new() in your loop and make new object each loop

hasty plinth
somber nacelle
#

in fact, literally all you need to do is just BlackHoleData[i] = stageManager.BlackHoles[i]; like you're doing for PlanetWeights, unless you need separate instances for whatever reason

rigid island
#

oh yea much easier ^

hasty plinth
#

Thanks for helping with my issue

the problem is that I have 2 identical BlackHole classes. One in the script I shared and one in me StageManager script. Is there a way to make them "Global" in some way?

But then I will need to reference it in my other script in some way

Anyone have any advice on controlling the timing/flow of a game when using an event based structure? Basically, the flow of my game is completely linear, so I need thinks to happen at specific times after other things have happened.

I currently have a game manager that manages the states (these are sequential and occur in series, with the exception of an idle state) and fires off different events sequentially in each state.

For example,
"SetUp"
OnShuffle?.Invoke()
OnDeal?.Invoke()

If shuffle completes after deal, then I have a problem.

vagrant blade
#

If you're doing it sequentially, then you can use a coroutine that yields to other things that have to happen. That gives you full control of the order of things, while allowing you to wait for things like animations, etc. to complete for each part.

plush ridge
#

and then wait for the finished event using a coroutine

vagrant blade
#

I wouldn't use events here, really

#

I would just reference the deck and stuff directly

#

That way you can yield return new WaitUntil (...) for them to do their thing/animate, before stepping to the next part

#

Or if they have coroutines, just yield return StartCoroutine(...)

plush ridge
#

I gotcha. I'll probably end up doing that. Thanks for your help!

#

ChatGPT came up with something kinda cool. Sorry to be douchie and share it right after you had suggested coroutines; but I still think it's pretty neat and wanna share it anyway lol

image.png
#

although doesn't work for passing parameters :/ you're right, direct references is the way to go.

vagrant blade
#

This does work, I've used this method before specifically for a turn based game.

#

You create "Template" functions PlayerTurnSetupTemplate() , PlayerAttackTemplate and queue a bunch of events based on what you want to happen, then pass it to some manager that steps through each event that was added in the template.

#

But it does lead to a lot of switches/if statements, which is why I prefer to just do things directly.

#

You don't need to be fancy about it, just make it work for your game.

Hello, how can I make the input system easier to use? What ways can I follow to prevent the code from getting mixed up?

gray mural
leaden ice
torn cedar
#

should i use events

gray mural
#

Events are useful if implemented correctly

leaden ice
#

You should use events for things where events make sense.

#

You should use polling (reading input in Update) for things where polling makes sense

torn cedar
#

I'm not doing anything very important, I just want to make it go back and forth with WASD. Even if I want to do something simple, I want to proceed with the best practice.

leaden ice
#

Not sure what you mean by "important", but for basic directional movement my recommendation is to poll the input data in Update.

#

Since it is a thing that continually changes

rigid island
spare dome
#

you optimize after your game is mostly made

#

or when all of your ideas are in fruition

Instead try to designate a key to something in something like a player controller and then send the event around. Makes it easier to control and prevent button presses from activating in certain situations.

Are there any issues with networking in webgl builds? I was thinking of a side project using a socket-ish (Telepathy for C#) library and headless c# server, but it might be nice to be a web client. Obviously there's a host of other problems (load time, no access to file system, etc) but... I'm just in the daydreaming stage so none of that stuff matters anyway. 🙂 FWIW I've built a mobile (and windows build) game with a server solution like this before so I could always go that route, but I'm just sorta thinking of the tech now

#

Another option would be a server that does everything with web based API calls but.. maybe makes for talking back to the clients harder without something like signalR

queen raft
#

if I use mousedelta from new input system (inputmap action), do I need to scale it based on platforms/window size? WebGL window size is small

modern creek

(Seems that WebGL pretty much doesn't allow anything in System.Net)

latent latch
# 
int numColliders = Physics.OverlapSphereNonAlloc(potentialPosition, AvoidanceDistance, terrainColliders, AvoidanceLayers);
if (numColliders == 0)
{
    GameObject spawnedObject = Instantiate(spawn.ObjectToSpawn);
    spawnedObject.transform.SetParent(transform, false);
    spawnedObject.transform.SetPositionAndRotation(potentialPosition, Quaternion.identity);
    positionFound = true;
    spawnedObjects++;
}```
So I have a problem with a editor script such that instantiating an object like this does not seem to get caught by the next iteration's filtering. However, if I instantiate it all in one line such as:
```cs
int numColliders = Physics.OverlapSphereNonAlloc(potentialPosition, AvoidanceDistance, terrainColliders, AvoidanceLayers);
if (numColliders == 0)
{
    GameObject spawnedObject = Instantiate(spawn.ObjectToSpawn, potentialPosition, Quaternion.identity, transform);
    positionFound = true;
    spawnedObjects++;
}```
It works fine, but the reason I don't want to use this method is because I want to instantiate prefab instances via PrefabUtility but that doesn't have the same instantiation parameters.
#

My guess is those additional method calls don't update till next frame when I'm looping over everything in one.

little meadow
#

@latent latch you mean the physics thing doesn't detect it? If so, maybe you need to call Physics.SyncTransforms or something... Oh, actually you can probably also manually update RB.position/rotation (if you have such)

latent latch
#

takes a little longer but works ;)

modern creek
#

@latent latch Also, depending on what you mean by "get caught by the next iteration's filtering", your SetParent(transform, false) is different than just passing the transform of the parent

#

(I don't think you want false for the 2nd parameter)

latent latch
#

Yeah, I was toggling that back and forth but no go

#

what's odd though is it doesn't work in a prefab scene.

#

Need to drag the terrain out onto the main scene and run it

#

had to make my own billboard populater because the terrain's auto population doesnt work with spriterenders I guess

unborn elm
#

What is best practive if I have a script that adds a delagate to an action OnEnable but then potentailly wants to unsubscribe during update? Is there any problems with having both an condition -= as well as one on OnDisable?

#

Kind of like this:

    private void OnEnable()
    {
        RunningSceneActions.OmPlayerPosChanged += ChangePos;
    }
    private void OnDisable()
    {
        RunningSceneActions.OmPlayerPosChanged -= ChangePos;
    }
    private void ChangePos()
    {
        if (activated)
        {
            RunningSceneActions.OmPlayerPosChanged -= ChangePos;
        }
    }
#

I can of course use the bool for a check on disable, just wondering if there are better ways?

knotty sun
unborn elm
#

Cool, thank you, it seemed to work but didnt know if it could cause some wierd stuff that i didnt notice

I'm using a Character Controller for an endless runner, you can control horizontal movement. I want to apply a small amount of rotation when moving left or right to make the movement feel more fluid.

My issue is that I can't really get the rotation amount to be framerate independent. On lower FPS there will be more rotation, and higher FPS will have less rotation. I calculate the horizontal movement amount in Update, use characterController.Move, then call SmoothRotate(horizontalMovement). I've tried various things, but still wasn't able to make it framerate independent.

private void SmoothRotate(float horizontalMovement)
{
    float rotationAngle = horizontalMovement * rotationMultiplier;

    rotationAngle = Mathf.Clamp(rotationAngle, -maxRotationAngle, maxRotationAngle);

    Quaternion targetRotation = Quaternion.Euler(0, rotationAngle, 0);

    transform.rotation = Quaternion.RotateTowards(transform.rotation, targetRotation, rotationSpeed * Time.deltaTime);
}

Here's the full test character controller code: https://hatebin.com/dqfnvbipgz

unborn elm
#

Weird, shouldn the delta time handle that?

hexed pecan
#

Where does horizontalMovement come from?

spice hill
hexed pecan
#

Like SmoothRotate(direction.normalized * speed).x)

spice hill
hexed pecan
#

You are effectively passing in a target angle. There is no reason for it to be multiplied by delta time

#

Can't explain it better at least right now, I have barely woken up

#

With higher framerate your deltatime is smaller so your target angle got smaller too

#

At low fps you might be rotating towards 45 degrees but with high fps towards 10 degrees

spice hill
#

Thank you!

I have created a helper script, which is supposed to shift the initial color's brightness.

Color.RGBToHSV(_initialColor, out float h, out float s, out float v);
v *= 1 + value / 100f;

_color = Color.HSVToRGB(h, s, v);

I convert it to HSV, change its value and convert it back to RGB.
Having a pure blue initial color, it properly shifts it to black on shift decrease, but stops at (0, 0, 0.7490196) (RGB 0-1) once shift reaches > 0, where 0 is the initial color.
Is there any way to properly convert it, since I'm sure pure blue adjusted with G and B at least seems brighter?

no, you can use something like NaughtyAttributes or Odin Inspector which i believe both have an attribute to select a scene from a dropdown for an int or string variable. or you could write your own property drawer for it (i did this, it's not too difficult)

Seems like PhysX has pretty similar determinism guarantees as Rapier, which are that if the data is the same, everything is done in the same order, compiled on the same toolchain ..... it's deterministic on the same device.

i wonder if modulo is slightly more optimal

but i guess both are pretty close

it's not something that happens too often

use whatever is most legible and make sense to you tbh

#

the difference are probably so minute they would serve no relevance

elfin tree
#

yeah i understand the first one better but i'd like to be able to think like the second one

#

i kinda get it cause i guess with that way it's at most 180 and then you remove 180 and you get a number between -45 and 45

rigid island
#

the +180 puts it in a positive range

#

the modulo is there to wrap it back, then -180 is just to get range -180 / 180

I have an insanely weird bug
Running this code makes the coroutine get stuck during the first yield
Changing Start() to OnEnable() solves the problem
What the heck is going on?

[SerializeField]
    private List<RectTransform> _titles;

    
    private void Start()
    {
        StartCoroutine(AnimTitle());
    }

    private IEnumerator AnimTitle()
    {
        foreach (var title in _titles)
        {
            title.localScale = Vector3.one * 30f;
        }
        foreach (var title in _titles)
        {
            var scale = title.DOScale(1f, 0.3f);
            scale.onComplete += () => _soundManager.CardPlayedSFX(CardPlayedSFX.Punch);
            Debug.Log(title);
            yield return new WaitForSeconds(0.5f);
            Debug.Log(title);
        }
    }
#

by stuck, I mean only one debug.log ever is displayed

#

Disabling an object cancels its coroutines. So presumably the object gets disabled and OnEnable restarts the coroutine

wintry crescent
#

and it does not get disabled here

#

also I specifically mean the first time the coroutine runs

#

if it's called from within Start it stops, if it's called from within OnEnable it doesn't stop

mellow sigil
#

Put this in and see if it prints:

void OnDisable()
{
    Debug.Log("Object disabled and coroutines stopped");
}
wintry crescent
#

okay what the hell

mellow sigil
#

You can't see it in the hierarchy if it's disabled and enabled during the same frame for example

wintry crescent
#

I guess technically it does get disabled and enabled within the same frame at the beginning

Why does netcode for gameobjects change lightning of the scene when loading it with NetworkManager.Singleton.SceneManager.LoadScene? The right one is the correct one, and i am using unity 2022 built in rendered netcode for gameobjects v1.10.0

Okay I don't really know where to put this so it is going in here. It is not coding per say but it has to do with editing components of game objects so I hope this is the right place. Essentially, my problem is that I have a 1bit sprite that I'll attach, and I feel like there has to be some automated way to get the polygon collider for it. Especially because it is literally just squares. But I have looked into creating a custom physics shape from the sprite shape and all that but I run into a problem: the bounding box decides to be just a little bit too wide. And so the polygon collider is too big and that is obviously something I would prefer didn't happen

     [SerializeField] private AssetReference assetRef;
    public bool T;

    private void Update()
    {
        if (T)
        {
            StartCoroutine(InstantiateCoroutine());
        }
    }

    IEnumerator InstantiateCoroutine()
    {
        AsyncOperationHandle op = Addressables.InstantiateAsync(assetRef);
        yield return op;
    }
#

Here i want to instantiate an object using addressable only once when the bool turns true. but the code instantiates it infinite times, i know cz i am using it in update. But i don't know how to do it correctly to instantiate only once, what to do?

well, actually i want to use it based on distance proximity, when player is near the target, i want the object to instantiate only once, then what should i do? again i have many objects in the list to activate based of distance proximity
