gotcha

quaint rock
#

up to you how you want to represent it, sure there are plenty knowledge or the topic around, this type of system is not exactly new

silent tapir
#

how would I utilize that 2d array though?

quaint rock
#

the 2d array represents each cell in the inventory grid, and what item is assigned to each cell, where 1 item might be assigned to many cells at once

silent tapir
silent tapir
#

Like I am not sure how an item is supposed to be in two slots at once

#

Because with a normal system I just keep the item as a child of the slot

quaint rock
#

break the problem down, first figure out a grid system, then how to click and drag to and from it with 1 item per tile

silent tapir
quaint rock
#

then how to effect multiple tiles at once

mellow grail
#

can someone please help? im getting the error "RPC method 'SwitchWeapon(String, Int32)' not found on object with PhotonView 1. Implement as non-static. Apply [PunRPC]. Components on children are not found. Return type must be void or IEnumerator (if you enable RunRpcCoroutines). RPCs are a one-way message." whenever i try to call the rpc in this script, both the script that sends and receives the rpc has a photon view and the rpc is listed on the rpc list.

📎 NetworkedPlayerManager.txt
#

I double checked the parameters too

silent tapir
#

the approach now for multiple tiles I need to figure out

#

@quaint rock so I got this gold I can drag around that is a 1x1, but then this rifle that is a 2x1. How should I child this? if I child it to a slot the slot next to it will obviously overlay over it.

quaint rock
#

would not make it a child of the cells, would just snap its position based on cell location

#

and each time something is dropped would update the array of which cells are occupied

silent tapir
#

gotcha

quaint rock
#

and while dragging someting around do the math to figure out which cells you are over and based on your items shape and are those cells occupied

silent tapir
#

okay

@quaint rock?

as my project grew this issue has become more and more common. unity gets stuck sometimes up to 5 minutes on this and im forced to terminate and restart unity once in at least 5 times after writing code and/or going into play mode. i tried assembly definitions but this issue still prevails. any advice would be ver welcome thank you in advance.

Hello, in a 3D project, my "OnCollisionStay" method is not called every frame, even if the rigidbody is awake, and moving. The research i did only mentioned setting "sleepThreshold" to 0, or keeping the rigidbody awake, and both of these solutions are useless.
Does someone had this problem before?

#

the method is called, it's just that it's not called regularly. I want this callback to be called every frame instead of every 10 frames or so. My detection mode is already set as "continuous"

#

already did

#

what do you mean by that, which timestamp?

heady iris
#

you should...not do this

#

this is going to screw up all of your game's physics

#

that will make physics update 10 times per second, rather than 50 times per second

heady iris
frank marsh
#

yeah, i wont change this value

heady iris
#

continuous collision detection helps to detect collisions that would otherwise be missed because you're moving too fast

heady iris
frank marsh
heady iris
#

Show your entire script !code

tawny elkBOT
frank marsh
#

actually, the only problem is that OnCollisionStay is called once for every 3 or 4 calls of the Update method, i'm affraid that the rest of code wont give much information

heady iris
frank marsh
#

the collision stays between these calls, since no OnCollisionExit is called

heady iris
#

OnCollisionStay is called once per physics update.

#

It isn't called once per frame.

#

If your game is running at 150 FPS, you will get three frames per physics update at the default physics timestep of 0.02

frank marsh
#

how to make it called once per frame, is it possible?

heady iris
#

You can't.

#

That's not how Unity works.

#

If you want to be able to check if you're currently colliding in Update, set a bool field to true when the collision starts

#

and set it back to false when the collision ends

frank marsh
heady iris
#

I don't see the problem.

frank marsh
#

i could, yes, i'm just thinking if it's a problem, if the normal is changing between these calls

heady iris
#

It's not changing.

#

Physics happens once per physics update (as the name implies)

#

It doesn't matter if your game is running at 500 FPS. Physics is only calculated 50 times per second.

frank marsh
#

Thank you very much for these informations

#

i will change my code

Hello, I have a problem with a Rigidbody. Basically, when I walk into another Rigidbody which is kinematic, my player character slides on top of it and when it gets off, it falls but very very slowly, so you are basically flying. I can provide any info, the Rigidbody for the player character is on screen.

heady iris
#

You could also use a particle system.

scenic sigil
#

Where is it?

heady iris
#

    }

        look.y += Input.GetAxis("Mouse Y");
        look.y = Mathf.Clamp(look.y, -90f, 90f);

        cameraTransform.rotation = Quaternion.Euler(-look.y, look.x, 0);
        transform.localRotation = Quaternion.Euler(0, look.x, 0);
    }
}
heady iris
#

yeah, you're setting your velocity to zero every physics update

#

gravity doesn't work very well when you reset your falling speed 50 times per second 😉

#

Consider just setting the X and Z parts of your velocity vector based on move input

scenic sigil
heady iris
#

removing MovePosition entirely

heady iris
scenic sigil
#

Set x and z to what?

heady iris
#

the velocity you want to move at in those directions

#

probably just input.x and input.z (both multiplied by moveSpeed)

scenic sigil
#

How do I translate my MovePosition into that accounting for moveSpeed

heady iris
#

input has X and Z components that depend on how fast you're trying to move in the X and Z Directions

#

just don't multiply by deltaTime and you have a velocity instead of a displacement

scenic sigil
heady iris
#

Yep, that looks reasonable.

scenic sigil
#

Used Roblox syntax instead of C# for the new()

heady iris
#

Do you have X and Z rotation locked on the rigidbody?

#

I can’t quite tell what’s causing that

scenic sigil
#

Not only with the camera

heady iris
#

oh, it’s jitttering up and down

scenic sigil
#

Yup

heady iris
#

That is very weird. The Y position isn’t changing

#

Ah, one thing: set the camera rotation after rotating the entire player.

scenic sigil
cosmic rain
#

Just mentioning a design pattern doesn't really explain what you have in mind.

scenic sigil
heady iris
#

since it is parented to the player

#

This got corrected on the next frame, as long as you stopped rotating the camera

scenic sigil
#

Also now that I'm not setting the velocity to 0 I don't fly because of the platform, but I can still slide up onto it

scenic sigil
vagrant agate
#

layer collision matrix is one way

#

i mean to be honest, your trigger could work for both. just when it triggers with an object you want to destroy the bullet just do it.

simple egret
#

The main disadvantage with triggers is that, if your projectile is too fast, you experience tunelling where the bullet passes through the target without firing OnTriggerEnter.
And the disadvantage of regular colliders is that the projectile stops dead in its path at the first collision

#

The middle ground would be to ditch the collider entirely, and manually check for "collisions" with a Raycast between the position of the bullet on the last frame and the current position

#

This allows you to loop through the detected objects in your path and apply logic whether to stop the bullet or pass through

heady iris
scenic sigil
heady iris
#

that was vague yeah :p

#

select the object with the collider and show me it in the scene view, as well as the inspector

#

if the rigidbody is on a different object, show me that as well

scenic sigil
heady iris
#

The player.

scenic sigil
#

The inspector doesn't fit in one image

#

What can I collapse

heady iris
#

just take multiple screenshots

scenic sigil
#

I squeezed all the necessary info in, only omitted my script and mesh filter

image.png
#

Ignore the jump power

#

It's unused

heady iris
scenic sigil
#

Lemme grab some footage

heady iris
#

It's possible that the capsule collider is causing a slight vertical force when it whacks into the wall

#

and since you're setting the velocity every physics update, it's like you're crashing into the wall at full speed 50 times per second

scenic sigil
#

Slight can't be enough for that

heady iris
#

Try this:

Vector3 movement = rb.velocity;
movement.y = 0;
movement = Vector3.MoveTowards(movement, input * moveSpeed, Time.deltaTime * 30); // accelerate at 30 m/s^2
rb.velocity.x = movement.x;
rb.velocity.z = movement.z;
scenic sigil
heady iris
#

Right.

#

This will gradually change your velocity each physics update, rather than just setting it to 5m/s instantly

#

I'm still a bit surprised that you're climbing the wall, though.

I'd also try replacing the capsule with a box collider, just for a sanity check

scenic sigil
#

Last 2 lines give compiler CS1612
Rough translation from Russian: "Failed to change the return value of "Rigidbody.velocity" because it is not a variable."

heady iris
#

oh right, d'oh

#

can't assign individual parts of the velocity

# 
movement.y = rb.velocity.y;
rb.velocity = movement;
#

that'll do

scenic sigil
heady iris
#

You want to keep that, since you don't want your current vertical velocity to affect the MoveTowards line

scenic sigil
#

Alright

heady iris
#

Otherwise, it'd "waste" some of your acceleration on moving your Y velocity towards 0

scenic sigil
#

Let me check if this works

#

It slides up slightly but not enough to get on top

Hi, what would be the best way to create world space health bars? I can make a world canvas for each of them, but I feel like it's too many canvases. I thought about creating a custom component with LineRenderers, but then I need to updated all positions every frame. Is there any better way?

must they be world space

could they just be screen space, then do a world to screen space transformation to decide where on the screen to render them

Quick question (I hope lol) So I have an incoming type and some parameters that I wish to setup an object with. I recognize that I can use activator.CreateInstance in order to do this but I can't seem to pass my delegate parameters into the method because it only takes objects.

IIRC Dani's grappling gun game doesn't use Rigidbody

knotty sun
#

sounds like it, mixing physics and non-physics is definitely non trivial

rigid anvil
rigid anvil
leaden ice
#

A grappling gun is inherently physical

#

that means you need to simulate physics one way or another

#

either using Rigidbodies and Uniry's built-in physics

#

or implementing gravity, momentum, forces yourself.

knotty sun
leaden ice
#

it's not that complicated if you do a hybrid setup using Unity's physics engine for collision detection. Basic velocity, momentum, and forces are quite simple.

I'm making an enemy that shoots a projectile with an arc at the player (or any valid target) and I'm considering whether to use DOTween or just a standard rigid body with physics.

I have both implementations working, but I am wondering if there is any wisdom regarding DOTween: is it generally better to avoid using the additional library if possible, or can it add maintainability value to the code if used properly? Apologies for the vague question

leaden ice
vivid halo
#

I want projectiles to follow various arcs when being fired from enemies toward the player. I can handle this with individual scripts or DOTween, but I'm not sure which would be better long-term.

Sine wave curve, corkscrew curve, standard projectile lob, and other arcs. I heard DOTween might be able to simplify this but I want to gather the thoughts of more experienced devs before I commit to it

Is there a good way to teleport an object into a valid position, I.E, if I have two characters overlapping after spawning them, and I just want to snap them out of the invalid position?

# 
public static void DropItemIntoSlot(RectTransform slotTransform, RectTransform itemTransform, Vector2 cellSize)

        {
            Vector2 gridOffset = slotTransform.parent.GetComponent<RectTransform>().anchoredPosition;
            Vector2 itemCorner = itemTransform.anchoredPosition;
            Vector2 relativePosition = itemCorner - gridOffset;

            Vector2Int cellCoord = new Vector2Int(
                Mathf.FloorToInt(relativePosition.x / cellSize.x) + Mathf.FloorToInt(gridOffset.x / 100),
                Mathf.FloorToInt(-relativePosition.y / cellSize.y) + Mathf.FloorToInt(gridOffset.y / 100)// Invert Y-axis
            );

            Debug.Log(gridOffset);
            Debug.Log(cellCoord);

            //selectedItem.transform.position = new Vector3(snappedPosition.x, snappedPosition.y, 0);
            selectedItem.image.raycastTarget = true;
            selectedItem = null;
        }
    }```

the grid only responds with the correct cellCoords if the gridOffset is set to 200 for some reason.
vivid halo
# leaden ice The Rigidbody will help you only with parabolic arcs

My instinct is to create scripts by hand like SinewaveTrajectory.cs or CorkscrewTrajectory.cs as physics mods and attach them to projectiles without using DOTween, but I am unsure of which path to take. Is the given information sufficient to recommend an approach?

Looking for some advice on where to manage object animations.

I have following classes:
Unit - monobehaviour, holds basic information about unit, initializes everything, firing some events
UnitAction - C# class, which performs various unit actions like heal, move etc.
ActionCommand - c# command class for Action that holds action and execution parameters
UnitActionsQueue - monobehaviour that executes queued Commands

Now I am not sure where to put code to manage animations. I will need to react for current executed action and external inputs like damage taken.

My current idea is to create another MonoBehaviour UnitAnimator which references Unit events + UnitActionsQueue and reacts to both sources. Since Actions aren't Monobehaviour on each change of action I'd need to add/remove listeners depending on currently executed action type. I guess it would work but not sure if it's good approach and isn't too complicated.

wide terrace
# silent tapir the 100 is the cellSize my bad.

Ok... I guess I still need more information on what the difference between "correct coordinates" and "incorrect coordinates" are. I'm a little confused by why gridOffset is factored out of itemCorner to get a relative position, then factored back in to cellCoords to produce coordinates which ignore that offset.

Like, if gridOffset is 200, 200 and cellSize is 100, 100, then the very first item on or after the gridOffset position (say it has itemCorner 200, -200/relativePosition 0, 0) has cellCoords 2, 2 instead of 0, 0 - is that correct, and your intended result?

Real quick before I do a bunch of work and tests on this, is it significantly slower to directly load floats, ints, etc. from a scriptable object every frame vs caching the scriptable objects data into local variables and using those every frame instead?

yeah, cache the scriptable objects and treat it as loading from a class

I am wondering if the fact that its a scriptable object introduces much if any overhead

note that fields are not local variables

a local variable is a variable you declared inside of a functino

Any advice on what to do with this issue? I don't like the jitter that happens with the repeated collision.

leaden ice

instead you are likely moving the Transform directly

twin jetty

#

To fix it - start moving your character appropriately with the Rigidbody2D

#

e.g. by setting its velocity

#

I also recommend enabling interpolation on your Rigidbody2D if it is not already enabled.

sharing your code would be a good start.

A typical standard movement script in 2D using velocity might be something like:

rb.velocity = inputVector * speed;```

# leaden ice sharing your code would be a good start.

It mean, it just represents a value. Pressing A would mean GetAxis("Horizontal") returns -1. D would return 1

Then you can make a vector directly from two get axis calls.
For 3d, you would want x to be horizontal and z for vertical

Vector3 moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical")).normalized;

Then you can just use that directly. A single line for input and plug it into your movement

Hi, Im trying to make a 2D bomb to destroy tiles, I made this code but is not working, it only destroys a single tile

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Tilemaps;

public class BombItem : MonoBehaviour
{
    Tilemap tilemap;
    public float explosionRadius = 1.0f;

    float destroyedTiles;

        tilemap = GameObject.Find("Destructible").GetComponent<Tilemap>();
        StartCoroutine(Timer());
    }
    IEnumerator Timer()
    {
        yield return new WaitForSeconds(timer);
        BlowUp();
    }

    private void BlowUp()
    {
        RaycastHit2D[] hits = Physics2D.CircleCastAll(transform.position, explosionRadius, Vector2.zero);

        foreach (RaycastHit2D hit in hits)
        {

            Tilemap tilemap = hit.collider.GetComponent<Tilemap>();
            if (tilemap == this.tilemap && tilemap != null)
            {
                Vector3Int tilePos = tilemap.WorldToCell(hit.point);

                tilemap.SetTile(tilePos, null);

                destroyedTiles++;

@cosmic rain This is my modloader code: ```cs

FileInfo[] info = dir.GetFiles("*.dll");

    foreach (FileInfo f in info) {

    }
}

void Update() {

}


My compiled c# dll looks like this:```cs

}

When I run this code I dont know how to attach the dll file to an object to make it run.

A Physics query is not the answer here

Iterate over all the tiles within the radius of the explosion.

#

Find the one in the center with WorldToCell then just iterate over the nearby ones

Something along those lines

Well, think. This is literally an example of how to create an instance and call a function on it.

wide terrace
# silent tapir I've tried everything.

I'm pretty rusty with GUI stuff, but I think it's still something wonky in the pivot/anchor... The math in your last code snippet looks fine to me - the coordinates make sense relative to that 210, 0 gridPosition - but it seems like that might be wrong position to start from. I suspect that you need to start from the coordinates of the left corner (or bottom left? Again, rusty :P), and that 210, 0 might not be it?

Like this would be functioning perfect if the cells were drawn down and to the right of 210, 0, but they're drawn starting from 0, 0

silent tapir
#

@wide terrace I have tried almost every single anchor and pivot, none of it works

#

you know putting it in the very top left and putting the anchors to a certain number until its close to 0 works. Is this a valid way of doing this?

image.png
wide terrace
silent tapir
#

What?

#

well the that would just be what it already is though?

wide terrace
# silent tapir What?

The anchor and pivot can move around within the object. But your cell coordinate space always originates from the top left corner. So instead of setting gridPosition from the rect's anchoredPosition, you need to find a way to ask the rect for the coordinates of it's top left corner, pivots and anchors be damned

silent tapir
#

ah okay

silent tapir
# wide terrace The anchor and pivot can move around within the object. But your cell coordinate...

so I just need to get the top left corner, lets see..

Vector2 anchoredPosition = gridRectTransform.anchoredPosition;

    // Calculate the top-left corner position
    Vector2 size = gridRectTransform.sizeDelta; // sizeDelta gives width and height of the RectTransform
    Vector2 topLeftCorner = anchoredPosition - new Vector2(size.x * gridRectTransform.pivot.x, -size.y * (1 - gridRectTransform.pivot.y));```
#

huh?

wide terrace
#

accidentally hit enter early :)

silent tapir
#

oh lol

#

im not utilizing the topLeftCorner correctly apparently bc it still don't work :/

# 
RectTransform grid = slotTransform.parent.GetComponent<RectTransform>();
            Vector2 anchoredPosition = grid.anchoredPosition;

            Vector2 size = grid.sizeDelta;
            Vector2 topLeftCorner = anchoredPosition - new Vector2(size.x * grid.pivot.x, -size.y * (1 - grid.pivot.y));

            Vector2 itemPosition = itemTransform.anchoredPosition;
            Vector2 relativePosition = itemPosition - topLeftCorner;

            Vector2Int cellCoord = new Vector2Int(
                Mathf.FloorToInt(relativePosition.x / cellSize.x),
                Mathf.FloorToInt(-relativePosition.y / cellSize.y)
            );```
#

@wide terrace

wide terrace
# silent tapir <@1097950947369562187>

I think RectTransform has a number of other members which look useful this that might let you skip the math, but maybe like

Vector2 topLeftCorner = grid.GetWorldCorners()[0/* or 1, 2, 3 - not sure which is the top left corner */];

but again - super rusty. Not sure if this is a great choice. Seek a second opinion 👀

Ideally the top left corner again. You could do it from the middle, but I think you might need to change your "floors" to "rounds"? I'm sort of just rambling at this point. I'll brb

That seems reasonable... I think it's using the bottom left corners of things for the calcs, and treating 0, 0 as the bottom left cell cord, increasing up and right... I'm not sure why it might go wrong.

I'm afraid to suggest anything else before I play with the UI a bit to get a better handle on it's coordinate system again, lest I lead you further astray with poorly thought out conjecture 😅

silent tapir

and ur good

silent tapir
# 
            Vector2Int cellCoord = Vector2Int.RoundToInt((itemTransform.GetComponent<RectTransform>().anchoredPosition - grid.rect.min) / cellSize);

now its kinda volatile whether it wants to go on the dot, 1 down, or 1 up

i will try FloorToInt

it works, just gotta fix the y as a -

final code:

RectTransform grid = slotTransform.parent.GetComponent<RectTransform>();

misty blade
#

I'm currently working on a card game where players choose troops and place them on a game grid. I'm having trouble figuring out how to use Unity solutions to achieve this.

I have a Troop class that inherits from ScriptableObject, containing data like its sprite, order in the deck, cost, health, etc. Each troop also has custom functionality: some attack in a straight line, while others attack diagonally.

I created another Troop-like class that inherits from GameObject, where the custom behaviors are implemented. The ScriptableObject Troop has a reference to the GameObject prefab to use the custom logic. This means I have an object with data and another with logic. However, for every data object, there needs to be a prefab with the proper custom script attached, which doesn't seem efficient.

I thought about moving all the custom logic to the ScriptableObject class and passing the Troop placed on the game grid as an argument. But this would require calling methods from the ScriptableObject that are in the GameObject, breaking encapsulation and leading to poor design.

I've never used ScriptableObjects this way before and am wondering how to properly design a system that won't cause problems later in development?

cosmic rain
#

The specific scriptable object could construct that plain C# class instance and provide it to your scene objects.

misty blade
#

Wouldn’t that require an SO to have a reference to a plan C# class? I’m not sure if it’s something that you can assign in editor

Hello, i would like to be able to change the dynamic friction of a specific rigidbody at runtime, and i dont see how to do it without modifying the physic material assigned to the rigidbody. It seems that unity wont allow the creation of phyisic material at runtime (i thought about creating one of them for each rigidbody with a "new"). Does someone has an idea about how i could do that without creating a large pool of physic material in the scene that i would assign and modify in script?

Oh, you are teleporting the platform? either switch to rigidbody then or calculate the velocity

Why do you even use a rigidbody on the platform then?

scenic sigil
plucky inlet

plucky inlet
#

Why? You have a rigidbody and want to attach its movement to your players movement, so the platform does not slip away while your character is stationary, right?

scenic sigil
#

Yeah, I want the character to go with the platform

plucky inlet
#

So either you need the velocity, which does not work when you use transform.position, or you have to move your player the normal movement + the movement of the platform calculated

scenic sigil
#

...?

#

Go ahead

#

Put it right after the backticks, not on a new line

plucky inlet
#

Maybe put it in a link on hastebin or whatever is suggested here? 🙂

scenic sigil
#

This part is pretty okay, though I'd add a [RequireComponent(typeof(SpriteRenderer))] before public class Enemy so that the SpriteRenderer is automatically added with this script

plucky inlet
#

What is your question about your script tho? like second opinion about what exactly?

scenic sigil
plucky inlet
scenic sigil
#

Like, what exactly do I need to do to keep the player on

plucky inlet
# scenic sigil Like, what exactly do I need to do to keep the player on

I could just rewrite what I wrote there 😄 So what part is not clear? Basically, you have a second movement input when standing on a platform. That needs to be taken into account. Easiest would be to add the velocity, if you would switch over to move it with rigidbody instead of transform. But if you dont want to do that, you might need to move your player towards the platform positoin, which is updating constantly. Not sure, how smooth this could go, thats why I suggested using rigidbody for your platform

scenic sigil
plucky inlet
#

So there are things in the general setup, that could be simplified, but not about the code itself. Instead of letting every enemy calculate its own distance in update, you could use the player and overlapsphere (if using physics) to detect enemies in range and then call them to shoot. That way, only one update would check instead of every enemy.

And, what is inverseMoveTime?

plucky inlet
#

just a speed value

#

multiplier for deltatime to speed or slowdown

scenic sigil
#

Does it like accelerate?

plucky inlet
#

Time.deltaTime is time between frames. so if you move from point A to B with a percentage of 0.1(Time.deltaTime for example), it will move 10% of the distance. And then next frame it moves again 10% and so on. If you set the multiplier to 2, it ould go 20% per frame and so on

i have a list with a queue of deleted indices and a second list mapping indices to post-deletion indices for the sole purpose of keeping the primary list's elements position stable after deletion when I could have just used a hash table

@plucky inlet Uhh the snippet in the answer is problematic... MovePosition only accepts 1 argument and has no overloads

    rb.isKinematic = true;

    // If you really need a precision down to epsilon
    //while (!Mathf.Approximately(Vector2.Distance(rb.position, end), 0f))
    // otherwise for most use cases in physics the default precision of 
    // 0.00001f should actually be enough
    while(rb.position != end)
    {
        rb.MovePosition(rb.position, end, inverseMoveTime * Time.deltaTime); // ???

        yield return new WaitForFixedUpdate();

    rb.position = end;

Writing a pretty complex character controller that utilizes the animator's built-in statemachine to handle the multiple different states.

Issue I'm having right now is that states can't really communicate with eachother (this seems to be a limitation of the animator's state machine?). The way I've solved this currently is by having each state reference the owner (the base player controller) and I've ended up having to add extra variables which are solely for trasmitting data between states.

This feels a bit ugly and hacky. The player controller class only handles applying forces to the rigidbody based on a movementVector, which is modified by states. Having it store variables that are solely for the states feels ugly.

#

It's difficult for me to talk in-depth about how everything is setup without basically doing a write-up of my entire codebase.

#

I could use animator parameters for communication, but a lot of this communication uses vectors, which aren't a supported parameter type

#

I could split the vectors into 3 float parameters, but that seems like it would get out of hand quickly

plucky inlet
#

And why not store the values on your character and. just let the state do its state thing and the controller handle the variables?

vale wharf
#

there's 9 states (one not pictured sinced it's not implemented yet). They're updated as long as the animation the state is a part of is updated

image.png
#

States and their behaviour are tightly coupled with the animations, which is why I'm using the animator state machine for this.

vale wharf
#

I think having a dedicated component called StateData might be better.

shaders don't "appear"

#

you can certainly enable or disable a renderer

#

i'm not sure why you'd want to condition that on the existence of a GameObject, rather than just having a component with a bool field on it

quaint rock
#

am assuming they got something like a version of a shader for when things are wet or something similar

#

personally i would handle that with a global shader float to blend in and out that effect and a global shader keyword to disable it fully as needed

Setting it back to null will tell you that it is not running

heady iris
#

Coroutine is like a ticket. You get one when you ask Unity to start a coroutine.

#

You can give Unity the Coroutine and tell it to stop running that specific coroutine.

#

I believe it's fine to call StopCoroutine with a null argument (and it definitely is to pass it a Coroutine that has already finished running)

#

In many cases, though, flinging null into a function that expects an actual reference will cause an error.

knotty sun

It's also more semantically correct

If a coroutine is executing, stop it

Kind of a weird question, How can I calculate how high a rigidbody will go when given a vertical impulse force? Furthermore, lets say I apply a vertical impulse force to a rigidbody and then press a button at a specific point in the rigidbodies trajectory, how can I determine what point along it's trajectory the rigidbody was when the button was pressed?

#

the point along it's trajectory should be a normalized value too (i.e. 0-1 where 0 is start of trajectory, 1 is end of trajectory, and 0.5 is the middle of the trajectory)

vestal arch
#

well, given the object's mass and gravitational acceleration, it's a pretty straightforward physics formula

#

v^2 = u^2 + 2as, J = mu
s = (J/m)^2/2g
i believe that should be it

Is that when the body returns to the height it was launched from?
Is it when it collides with something in the scene?

heady iris
#

If you assume it's going to hit the ground at the same elevation it started at, it's actually extremely simple

# 
Mathf.InverseLerp(verticalSpeed, -verticalSpeed, rb.velocity.y);

where verticalSpeed is the starting vertical speed

#

The acceleration due to gravity is constant.

#

To calculate verticalSpeed from an impulse, you need to combine:

  • the original y velocity
  • the added y velocity from the impulse
#

An impulse of magnitude 1 changes your momentum by 1

#

Momentum is mass times velocity

vale wharf
#

I suppose end of trajectory in my case would be the peak height it reaches

heady iris
#

Divide the impulse's magnitude by the mass to get the change in velocity

#

so

var delta = impulse / rb.mass;
float startSpeed = rb.velocity.y + delta.y;
heady iris
#

note that this does not account for drag

Use case is for a 'hover' state in my character controller. When player holds space after jumping, they start to hover (this will only happen if the player is not on the ground becase they jumped, not because they fell off a ledge or whatever). When they started hovering (i.e. at the peak of the jump trajectory) influences how long they hover

so I have a vertical layout group which contains PlayerRow's of a few UI items. I want the entire row to be clickable like a button, so I put a Button component on my PlayerRow and used the Image of the row as the Target Graphic for the Button... It basically works but the problem is that i have to click several pixels below the visible row to hit the button, how can i make it so that I can click on the correct spot to click the button?

#

I have to click below the button in that area to hit the button, but it should work by clicking the Player One row instead..

okay, so if i set the image on the PlayerRow to Native Size, then it works... but would prefer not having to do that...

float moveVertical = Input.GetAxis("Vertical");

i have encountered an issue regarding a pretty hastely put together enemy spawner for a little game i am trying to make, the issue is that my coroutine seems to run a small part of the code inside of it twice without upping the iteration counter nor the coroutines counter while still changing some values which causes an error

no prob!

#

By the way, a handy way to spot this is to add a second argument to Debug.Log

#

You can add a "context" object (any Unity object, like a GameObject, a Material, etc.)

#

clicking on the log entry will take you to the context object, if it still exists

Yeah i used that before on another thing, but i didnt realize this couldve been the case on this thing, but maybe its good practise to just use context on debug.logs standard

Hey folks! Here's a fun question. For inconvenient reasons (let's not get into it), I need to instantiate a clone of a static object in a new location. Naturally Unity does not want to do this, since it requires moving a static object. Is there any way to force it to do this anyway?

#

So far I've tried:

  • setting the static flags of the clone to false, then moving it
  • setting the static flags of the original object to false, then cloning it, then moving the clone
  • setting the static flags of the original object to false, then instantiating the clone already at the position i want it
    None of these have worked so far.

why not just make a prefab out of the object and spawn that in ? why clone the static?
the static object becomes part of a larger mesh

I know what a command pattern is. But depending on how exactly you want to use it, the response would be vastly different.

From your example, it seems like you want the commands to interact with the unity API. In this case the answer is simple: you can't call most unity API from background threads, and even more so from jobs. Unity will throw an error if you try to do so.

What will happen if you put a reference type in a struct? Assume that the **struct **is stored in the heap.
• Will it give you copy of the value and it wont overwrite even you changed something of the value? // It will give you it's memory address
• What will happen if you overwrite reference type inner values? // Since you have it's memory address, it will change inner values of the class
• What happens if you put a delegate in struct and take from struct? Will it copy or give you it's address? // Delegates are immutable. If you try to change their inner value via +=, then you create new instance which means you cannot change anything important of a delegate.

Trying to code the "hover" state for my character controller. When player holds space while in air after jumping, the player should start to hover.

I want the motion of the hover to be physics and procedural. Basically, it should modulate vertically along a sine wave that slowly fades out the longer the player hovers. As the sine wave fades out, gravity pulls the character more until they hit the ground.

image.png
#

This should be a force applied to the rigidbodies Y velocity

#

not entirely sure how to achieve this, however. Obviously I know what a sine wave is and how to make one, but I don't know how to specifically get the behaviour I just described.

leaden ice
#

A PID controller that isn't tuned properly will overshoot and correct itself resulting in a wave like this

#

So you can intentionally tune it this way

vale wharf
#

Wouldn't that only really work if I had a specific height the player should be hoverng at? The hovering motion I'm envisioning is essentially like a paper bag under a fan (see animation) or a piece of paper fluttering through the air

Hey guys, I was wondering if someone can help me look for any improvements that I can make to the code for my player movement script. Since this script depends the player states, I already know that it would be ideal to have a state machine using abstraction instead of using enums. Are there any other advices?
Here is the entire code: https://gdl.space/ajefesulab.cs

#

for example, is it a good idea to run a switch statement in the fixedupdate the way I did it?

dusk apex
#

Tip: avoid premature optimization and use the profiler if there are critical concerns

keen raptor
#

what do you mean?

cosmic rain
#

Basically, if it works, don't touch it.

#

Though, I'd say that you should probably avoid using public fields.

dusk apex
cosmic rain
#

The only thing that stands out is the use of public fields. That should be refactored to serialized private fields and properties if public access is needed.

keen raptor
#

there is one thing in the code that does not work however. So basically, I have been trying to detect a side switch (meaning detecting if the player went from left to right and vice versa), but the condition does not always return true when I am switching sides. Here, ill summarize the code so that you don't have to look at for it:

    void update{
        PreviousMovementDirection = CurrentMovementDirection;
        if (Input.GetKeyDown(KeyCode.A)) CurrentMovementDirection = -1;
        else if (Input.GetKeyDown(KeyCode.D)) CurrentMovementDirection = 1; 
        EnabledSideSwitch();
    }
    private void EnabledSideSwitch(){ //I use hasSwitchedSides variable as the value that determins when the side switch occures which is used in multiple part in the 
        if(PreviousMovementDirection != CurrentMovementDirection) hasSwitchedSides = true; 
        else hasSwitchedSides = false;
    }

what could be the issue here?

dusk apex
#

Where do you call enable side switch?

#

Also, nothing is returned so I'm assuming you're referring to the value of has switched sides never being true

keen raptor

Assuming you can only be facing left or right, you probably could get away with simply a boolcs private bool facingRight; public bool FacingRight { get => facingRight; set { if(value != facingRight) faceHasChanged(); facingRight = value; } }

Instead of creating fields and getters/setters for everything, you can just opt to use properties.

#

Debugging code is simple:
Something doesn't happen? What are the conditions for it to happen? Where is it called from? Are the conditions satisfied when you expect them to be satisfied? Are they satisfied when the code is called? If not, then where are they satisfied? When do the relevant variables change? Are they changing properly? Are they resetting to a different value before the condition is checked?

It's all simple logic. And you can use debug logs or breakpoints to confirm all this things. Don't work harder. Work smarter.

Would unity be causing me to get this error? All the sourceNames use nameof(method), and all the methods are private statics in the same class that return IEnumerable<T>s (where T is some type like uint) as the ValueSource attribute. Also, why is it looking for a dll in that location??

so I think the problem here is that this value changes too quick for the values to return "-1 1"

cosmic rain
keen raptor
# cosmic rain What do you mean by "too quick"? Break it down. Then confirm the assumption. The...

Here ill break it down. So the update function is running each frame, and when there is a change in the current value, the previous value will change with it but not immediately. So we make an if statement that checks if there is a change or not. Now, just for some testing purposes, I made and if statement that checks if there is a change in the values, it would print out a message, which it did on every turn. But if I place a function with that same if statement and sets a value to true when there is a change, it does not always detect that change. Why??

#

maybe using Dalphat's code might fix this issue?

//Dalphat's code
private bool facingRight;
public bool FacingRight 
{
    get => facingRight;
    set
    {
        if(value != facingRight)
            faceHasChanged();
        facingRight = value;
    }
}

how do i get oncollisionenter working for an object that has a rigidbody in the root and all colliders in children? as far as i can tell a script only gets a call to oncollisionenter if the rigidbody and colliders are on the same gameobject. checking from the children where the colliders are yields no results, and checking from the parent with the rigidbody only also gives nothing. it only works if i have a rigidbody on the same object as the collider

#

wait i may be dumb

#

yeah i edited a prefab thinking it would change the thing but i forgot i unpacked it facepalm
though looks like unfortunately it still only registers that on the rigidbody object, not the collider object

I feel like I'm going insane. Is there any reason this shouldn't work?
All the variables look correct, but lerping the audio source volume does nothing.

// called every frame
_slideAudioSource.volume = Mathf.Lerp
(
    _slideAudioSource.Source.volume,
    _slideTargetVolume,
    1f - Mathf.Exp(SlideResponse * deltaTime)
);

Well that Lerp function is being used wrong for one. But, 1 - Mathf.Exp(20 * deltaTime) is going to pretty much the same number every frame since you're doing Mathf.Exp(20 * ~0.0045)

#

I think you actually want something like Mathf.SmoothDamp

autumn field
#

I use exp lerp everywhere and it works, its just a more responsive version of the traditional lerp damping.

 ```cs
public class VolumeTest : MonoBehaviour
{
    public AudioSource source;
    private bool flag;
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))
        flag = true;
        
        if (flag)
            source.volume = Mathf.Lerp(source.volume, 0f, Time.deltaTime * 0.5f);
    }
}
```~~~
#

Ah Im missing a negative i think

shell scarab
autumn field
#

This is a very common technique I promise

shell scarab
#

and I promise you, it's wrong to do it like that, because lerping interpolates between x and y, so if you lerp between CURRENT and TARGET by a delta time, you'll move a slight % of the distance between CURRENT and TARGET every frame, and then the next frame CURRENT is different, so you never actually reach TARGET.

It's not proper use of it, but if you're aware of that and don't care then go ahead :)

autumn field
#

I am aware it is not *perfectly consistent perfect depending on framerate

shell scarab
#

thats not what I mean, I mean that you don't ever reach your target.

#

Anyways, how does 1f - Mathf.Exp(SlideResponse * deltaTime) work? it seems to me it should just do 1 - Mathf.Exp(20 * ~0.045), but it works as a lerp for you?

# shell scarab thats not what I mean, I mean that you don't ever reach your target.

you don't ever reach your target
Yes I know. It's fine 👍, it will get very very close very quickly to the point that it might as well be 0 for use-case.

@cosmic rain Yea I was missing a negative. It is working now with -SlideResponse

slideSoundSource.Source.volume = Mathf.Lerp
(
    slideSoundSource.Source.volume,
    _slideTargetVolume,
    1f - Mathf.Exp(-SlideResponse * deltaTime)
);

I don't see a debug log here

shell scarab

dilch they said it works why would they provide a debug log, how would they

cosmic rain
#

But if you got it working, the issue is solved I guess

autumn field
#

Here's the debug.log 😛

Debug.Log($"Volume: {slideSoundSource.Source.volume}, Target: {_slideTargetVolume}, New: {Mathf.Lerp(slideSoundSource.Source.volume, _slideTargetVolume, 1f - Mathf.Exp(SlideResponse * deltaTime))}, Delta: {1f - Mathf.Exp(SlideResponse * deltaTime)}, Delta Time: {deltaTime}, Slide Response: {SlideResponse}", slideSoundSource);

How do you guys debug a character controller that has recently started to randomly accelerate into shear infinity for no reason? I didn't change any of the code.

it just started happening randomly a few moments ago

because why would the movement code break if I didn't touch it?

The debugging procedure doesn't change regardless of what your assumptions are.

Turn it off then back on again. If it's still the same, start looking at what the values are, and why 👍

autumn field
# shell scarab how does the math expression work? I'm not able to wrap my head around it. When ...

The t value is very small because it's happening every frame, but over time those small change result in it moving towards its target value and easing out as it approaches since t always moves it a percentage towards its target value from its current value, and that distance is getting smaller, it moves slower. So as you say, it never arrives, but if you multiply t by a large values it approaches quite quickly

shell scarab
#

I guess I don't understand the point of 1f - Mathf.Exp(-SlideResponse * deltaTime)

autumn field
#

Yea I might be bullshitting about that exp "responsiveness" part. I've just seen it done quite a few times in different articles/videos, but since you mentioned it I tested it and don't really see a big difference. It might have something to do with not surpassing 1 with t at low framerates

shell scarab
#

For example, why not just put 0.1 in?

            transform.position = Vector3.Lerp(transform.position, targetWorldPosition, 1f - Mathf.Exp(-Time.deltaTime * speed));
    }

Nice visualization

at this point I'm at a loss for words, because that was a stable save, and I have absolutely no idea why its breaking all of a sudden

lean sail

This is the standard for "I changed nothing and it stopped working!" You either changed something, or it was always broken and you didnt realize.

simple ruin
plucky inlet
#

Or you used a new editor or packages updated themselves or what not, but if you dont have any repo going, only you can tell what has changed, which you cant obviously

cosmic rain
lean sail
simple ruin
plucky inlet
#

Or refactor and be happy to learn something. We all have been there trying to fix broken code and in the end spending more time than refactoring it in a whole

#

Which would imply debugging anyways 😄

simple ruin
#

ive been here for a week of sleepless nights debugging and just when I'm about to push this shit happens

#

fuck this

cosmic rain
# simple ruin its so terribly designed I dont know where to start, fuck me

Start from thinking about the issue. Is it moving too fast? What is movement? Movement is the change in transform.position. it's either changed by your code or by one of the unity systems(physics, animation, etc..). Find what's moving the character. Then debug the involved values and see how they change and when.

plucky inlet
#

And please create a repo for your project

simple ruin
simple ruin
plucky inlet
#

So if you disable your character controller script, its not moving at all, right?

#

Also any logs in console?

lean sail
#

You could do a sanity check of restarting and even reopening scenes. I vaguely remember an issue I had, where my pc shut down overnight while unity was open. When I reopened unity, certain physics stuff were very buggy.

simple ruin
#

cant disable the character controller script since too many things rely on the script being defined

plucky inlet
#

Also debug.log your inputs coming in for your character to move. do they ever reset

cosmic rain
#

Other than that, you'll need to share more details about your setup.

simple ruin
#

well I found the source of the bug it seems

#

I had the camera set at 0.65 when its supposed to be set at y = 0 relative to the character

#

i don't know why setting it to y = 0.65 absolutely breaks my movement code but im so fucking tired I can't be bothered

Any idea what's wrong with this? I added this on my Volume profiles. But even when I enter them and all other effect pop, this one is fully ignored and I can't find a way to make it work.

    public class DirectionalLightEffect : VolumeComponent, IPostProcessComponent
    {
        public ClampedFloatParameter intensity = new(1f, 0f, float.MaxValue);
        public ClampedFloatParameter indirectMultiplier = new(1f, 0f, float.MaxValue);
        public NoInterpColorParameter color = new(Color.white);

        public bool IsActive()
        {
            return true;
        }

        public bool IsTileCompatible()
        {
            return false;
        }
    }
#

I have this, I 100% enter this volume (all other effects are visible), but all colors from VolumeManager.instance.stack.GetComponent<DirectionalLightEffect> are always default at whatever I specified by default (Color.white)

Hi guys ! I have a FPS issue... In my app, it's always at 72fps but, when i upload some files on my sftp server (asynchronously) in this moment precisely i have a frame drop below 60fps, and it's really annoying. Any idea why/how to fix this ?

Yeah it's the upload function, but i dont know why since it's asynchrone. Maybe i didnt understand the asynchrone system well, but i had in my mind that was the answer to an issue like this

Hello swarmknowledge. I have a logic question about adding some kind of "editmode" to my application. Right now, I have different behaviours running in the scene and reacting to different roles. What I am trying to achieve now is some kind of editmode toggle, that just triggers certain behaviour. I want to make the footprint on each component as automatic and small as possible, so I thought about using an interface. What I am wondering is, is there any advantage in using this against just a global boolean, which I will just check on the components?

fleet gorge
#

use a global boolean, perhaps a static variable. in the update of each component, if editing you can just return immediately

lofty summit
fleet gorge
#

quick method would be to have a camera write to a render texture, and on the next frame you can stop the main camera from referencing the render texture.

it doesn't have to be your main camera either, it can be an orthographic camera somewhere in your world with an image plane in front of it

#

under Camera

image.png
#

even if no cameras are writing to the output texture, the texture won't change. so you can have the camera render for one frame and destroy the camera afterwards

#

could you take a screenshot of your editor with the bulletprefab and bulletrelease fields during runtime?

#

its possible that somewhere in your code, you call Destroy on bulletPrefab by accident

#

so its working now?

empty dagger
fleet gorge
#

to clarify you're getting the error even when bulletprefab and bulletrelease are set?

knotty sun

instead of just outputting text why not show which one is actually null?

based on some research lidar can apply to multiple platforms, like android/iphone as well as embedded

#

Haven't been following. What's the problem in your prefab not being assigned?

#

Can't you simply.. assign it?

#

"Bullet prefab not assigned." is what I was able to read from your previously sent error

#

bulletPrefab is only used 3 times in the script. I see no way for its assignment to be removed when entering play mode

#

Do other scripts interfere?

#

Or is it not assigned?

knotty sun
#

where do you Destroy the bullet? It's not in that code

gray mural
#

Please, show it

#

Please, show the bullet's inspector

#

And where it's serialized

knotty sun
#

Is bulletPrefab also a GameObject in the scene?

gray mural
#

So could you show both objects?

#

Both

#

Bullet and where it's serialized

#

Neither of both scripts should be causing the prefab to be removed

knotty sun
#

Try this.
Disable the Bullet script on the bulletPrefab and enable it on the instantiated bullet

gray mural
#

The gun shoots a bullet and its reference disappears?

knotty sun
#

exactly. So you enable the Bullet script on bullet when you Instantiate bulletPrefab

gray mural
#

Yes

knotty sun
#

that is where you Instantaite is it not

gray mural
#

Also, is the bullet prefab even in your Assets?

heady iris
#

No.

#

because then the prefab instance would destroy itself after a few seconds.

gray mural
#

So you instantiate the bullet, and its reference disappears right away?

heady iris
#

update your Debug.Log calls to also include this as the context object

#

this will let you find out which object, exactly, is producing the message

# 
Debug.Log("Foo", this);
