As the player playing the game, what would I notice?

latent latch
#

having a microhiccup between platforms would be certain death for my character

#

so yeah, probably best to optimize what I can here

shell scarab
#

so there's a lag spike whenever a new shader is shown?

#

Have you tried using the profiler to see to make sure it's a shader prewarm issue?

#

look for these markers, if they aren't there then it's not that I'm guessing

latent latch
#

profile in editor is fine. It's just built webgl and dev version that causes it.

shell scarab
#

so build a webgl version and connect the profiler to it

latent latch
#

Ill probably have to read into the docs more, there may be something specific on webgl

#

there is shader spikes, yes

shell scarab
#

what version of unity?

latent latch
#

2022.3.28

shell scarab
#

ah, well it's not a 2020 bug that people were apparently complaining about

latent latch
#

going to try the other WarmupAllShaders method once it takes 15 minutes to build this thing

#

other than that, I'll stick with the camera idea for now I guess. Jam is ending anyway

#

the audio flags do work though so ty for pointing that out

shell scarab
#

The manual does say that while using dx12, Vulkan, or Metal the best option for preloading is to render something using that material off-screen.

latent latch
#

interesting, so similar to what everyone does in godot too eh

shell scarab
#

based on what it was saying, there doesn't seem to be a very good solution to it

#

Whats a good way to make text size scale with screen size.
All UI scales with resolution which in turns scale with screen size(i.e. your images/UI will take same amount of % space on big TV vs phone)
But this doesn't seem to apply to text.

#

Actually its because of the canvas I think šŸ˜

heady iris
#

show an example of the problem as well as the inspector for the canvas and the problematic text component

#

Currently I have a working hex map generator that generates based on a width and height value. I would like to convert it to generate the tiles in the shape of a hexagon (so hexagon shaped tiles while the overall map is also shaped like a hexagon). It really is just a math problem but I cant quite figure out how to go about it. Here is my method that generates the tiles off the width and height currently private void GenerateGrid() { for (int q = 0; q < gridWidth; q++) { for (int r = 0; r < gridHeight; r++) { CreateHexTile(q, r); } } } The offsets for the tiles position is handled in another method, but i dont think that is needed to alter this, I should just be able to alter the for loops of the method above to instead of looping to create a box shape, loop to create a hex shape?

Screenshot_7.png
heady iris
#

You may want to switch from rectangular coordinates to hexagonal coordinates

#

actually, how do your coordinates work right now?

#

does it offset every other row of tiles?

marble ember
#

yes it follows a tutorial by CodeMonkey return new Vector3(q, 0, 0) * cellSize + new Vector3(0,0,r) * cellSize * VERTICAL_OFFSET + ((r % 2) == 1 ? new Vector3(1,0,0) * cellSize * HORIZONTAL_OFFSET : Vector3.zero) + gameObject.transform.position;

heady iris
#

you might want to just use Unity's Grid class, actually

#

You can use it to compute world positions for a hexagonal positions

marble ember
#

ok i will start looking into that then as an alternative, thank you

heady iris
#

hm, but that doesn't really answer your question: you need to be able to compute grid cells to create a hexagonal shape

marble ember
#

yeah either way i think im gonna end back up at trying to figure out the right for loop combination to get the right number of tiles in each row

heady iris
#

but doing that recursively would cause a ton of overlaps

#

if you found the neighbors of all six of your neighbors, you'd visit many tiles more than once

#

also, both your code and Unity's grid system are using regular 2D coordinates

#

these may be less convenient than cube coordinates, where you use three dimensions

#

this talks about how that works

marble ember
#

ooo
ooooo
ooooooo
ooooo
ooo

#

Well that didnt work like i expected lol but i figured id be able to achieve this with some type of for loop

#

Like the first row it would generate whatever length i have set for the side, then 2 extra for each additional row until the diagonal side is equal to the side length as well then looping back down

shell scarab
# 
    public override float Process(Info info)
    {
        var pos = info.position;

        float r = Mathf.Max(info.height * noise.cnoise((_offset + info.position) * _perlinMultiplier), _minStrength);
        float x = Mathf.Max(info.height * Mathf.PerlinNoise((_offset.x + pos.x) * _perlinMultiplier, (_offset.y + pos.y) * _perlinMultiplier), _minStrength);

        Debug.Log($"r: {r}, x: {x}");

        return Snapping.Snap(r * _heightMultiplier, _heightSnapping);
    }
```Shouldn't these two lines give the same outputs?

looks like there's perhaps a little conversion to do

shell scarab
#

I would love it if they put the range of the noise method on the docs for the noise method

#

looks like the range is -1 to 1 instead of 0 to 1

leaden ice
#

yeah looks like it

#

Alot of Unity.Mathematics documentation is pretty weak

shell scarab
#

I agree

#

its like they expect it to be intuitive

#

yet make it slightly different than Mathf

dense estuary
#

I have a radar script that detects objects and displays icons on a screen, currently I have an issue where icons are not fading out whatsoever. This is my code for the fading: ```cs
iconImage.color = startColor;
yield return new WaitForSeconds(0.5f);
float time = 0;
float duration = 2f;

while (time < duration)
{
iconImage.color = Color.Lerp(startColor, endColor, time / duration);
time += Time.deltaTime;
}```

#

This is in a coroutine that is started every frame

#

Currently it appears that this code is making the icon instantly transparent

latent latch
#

is it opaque

dense estuary
#

The icon?

#

Its a ui element

#

image

latent latch
#

ah so no custom shader either

#

does the vertex color slider work outside of code?

#

oh wait you got a while loop here that doesntbreak

dense estuary
latent latch
#

always should have yields in your while loops

#

else a chance for šŸ’€

leaden ice
#

since it seems to be trying to do something over time

#

without a yield, the entire loop runs within a single frame

#

hence no fading

dense estuary
#

Oh! That makes sense, thank you!

shell scarab
#

Oh hey, they changed how nested monobehaviors are displayed! I seem to remember the name looking a bit bugged and not orderly. (Unity 6)

leaden ice
#

When you say "nested MonoBehaviours" does that mean multiple MBs in one script file? Or maybe MB classes defined within other classes?

You mean technically ? They might have simply made all mesh for every size and just swap them at runtime for the "animation". Alternatively, you could do some sort of mesh manipulation to add triangle between two side. Pretty much sure it is not real elastic physics.

errant flame
# barren sigil I can't figure it out how it work

IDK but the first approach to my mind was to create a structure that will hold a three-dimensional point data, and then according to the data here, we can somehow handle point - line rendering and then make a render order according to the y layer with the line renderer as an x-z example, maybe can go through it or it can be adjusted with layers with custom render feature.

@barren sigil

I don't think it can be done in a physics-based way, at least not in a cheap way.

I think we can go over it and predict where it can stop.

We need to establish a block logic between the layers. When we set a calculation limitation using these data layers, I think there will be the algorithm you want.

x mean blank
f mean filled

Layer 1 [f,x,x,x,x]
[f,x,x,x,x]
[f,x,x,x,x]
Layer2
[x,x,x,x,x]
[f,f,f,f,x,x]
[x,x,x,x,x]
Layer 3 etc

steady moat
#

You could even be more crude and simply state
If RED is not done,
Blue is blocked at: X.

steady moat
barren sigil
errant flame
#

idk but its not limitative i think for example first layer one f-f-f is blue one and layer2 f-f-f-f is red one if we release blue one we can predict where can it be stopped and update , or it could be a method like you said

So I have made progress on my issue i posted earlier using this source: https://stackoverflow.com/questions/20734438/algorithm-to-generate-a-hexagonal-grid-with-coordinate-system but the code doesnt seem to exactly translate to C# as I get overlap and have tried messing with the offsets and cant achieve perfect alignment, heres my c# translation of the source ```double ang30 = 30 * System.Math.PI/180;
double xOff = System.Math.Cos(ang30) * radius;
double yOff = System.Math.Sin(ang30) * radius;
int half = size / 2;

for (int row = 0; row < size; row++)
{
int cols = size - System.Math.Abs(row - half);

for (int col = 0; col < cols; col++)
{
    int x = (int)(gameObject.transform.position.x + xOff * (col * 2 + 1 - cols));
    int y = (int)(gameObject.transform.position.y + yOff * (row - half) * 3);
    Vector3 location = new Vector3(x, 0, y);
    Debug.Log("row " + row + " col " + col + " x " + x +" y " + y);
    CreateHexTile(location);
}

}``` where CreateHexTile simply instantiates the tile prefab at the location. Any ideas?

Thanks guys, i will try and test it

marble ember
#

I changed some of the data types and casted to float instead of int and got it really close, theres only a very tiny gap in between tiles but almost completely unnoticable so imma just settle with that. Probably due to the loss of precision with floats

gray mural
#

Well, how would you create more than 1 MonoBehaviour in a single script?

shell scarab
gray mural
#

Have you read the previous messages too? I cannot find the script they've sent, as they have deleted it. I suppose, there were GameManager and Singleton<T> in a single script. As I have mentioned above, it should've been Singleton<T> : MonoBehaviour and GameManager : Singleton<GameManager>. Both MonoBehaviours.

gray mural
shell scarab
gray mural
# shell scarab no it doesn't

I thought there should have been some kind of an exception thrown, but Unity just acts as the 2nd behavior doesn't exist

#

Anyway, left me refactor what I have previously said. You cannot have more than 1 MonoBehaviour run in the same script

shell scarab
gray mural
# shell scarab wrong again :(

Alright, could you provide me with the code which has e.g. 2 MonoBehaviours, both with the Start method, and both of them execute perfectly?

shell scarab
#

sure, let me start unity

shell scarab
#

(warning is unrelated - not sure why it's happening tbh, but it's not because of multiple monobehaviors in a script file as you can tell from reading it)

gray mural
# shell scarab

Well, you just add those script to the object from your main script. You cannot add Test and TestTwo manually

#

They won't run if you don't add them

#

This way, they simply act like the Behaviours, which don't exist as the separate scripts

So, my bro and I are trying to use physics and rigidbodies to control a player character and vehicles. But we're running into a bit of a snag.

How do we implement a way to apply directional force to a rigidbody that both a player and vehicle controller can use?

somber nacelle
#

apply directional force to a rigidbody that both a player and vehicle controller can use
what do you mean by this?

arctic sparrow
#

Well, he's kinda learning to program. He might be getting something wrong.

#

But imagine like a big air vent or fan or something that could push players around, but also vehicles.

azure frost
#

That, or an explosion, or jump pad.

somber nacelle
#

have you looked at the rigidbody docs to see what methods you might be able to use for that?

arctic sparrow
#

Well, on the player controller script, we tried to use a Rigidbody.AddForce() function with VelocityChange, but a trigger that adds force doesn't seem to do anything when the player passes through it.

somber nacelle
#

sounds like something is wrong with your setup. trigger colliders have nothing at all to do with whether or not force is applied

arctic sparrow
#

Well, it's sort of like this...

public void OnTriggerEnter (Collider other) {

  other.GetComponent<Rigidbody>().AddForce(Vector3.one*5);

}
somber nacelle
#

have you confirmed that method is running?

arctic sparrow
#

Yeah. I used a Debug.Log.

#

Do I have to include the Rigidbody's current velocity in the AddForce() function?

somber nacelle
#

no. if that is not adding any force, then it is either not enough force to overcome any current velocity in the opposite direction, the rigidbody is kinematic, or you are overwriting the velocity elsewhere

arctic sparrow
# 
private void FixedUpdate()
{
    float maxForce = 99999999;

    //Find target velocity
    Vector3 currentVelocity = rb.velocity;
    Vector3 targetVelocity = new Vector3(movement.x, 0, movement.y);
    targetVelocity *= movementSpeed;

    //Align direction
    targetVelocity = transform.TransformDirection(targetVelocity);

    //Calculate forces
    Vector3 velocityChange = (targetVelocity - currentVelocity);

    //Limit force
    Vector3.ClampMagnitude(velocityChange, maxForce);

    rb.AddForce(velocityChange, ForceMode.VelocityChange);
}

Here's the code. We used a video reference for this

somber nacelle
#

okay well this shows you are not overwriting velocity here

tall scroll
#

How is the player rigid body ā€œattachedā€ to the vehicle one?

#

Like what causes the player to move with the vehicle

arctic sparrow
#

Well, when the player would get in the vehicle, we plan on having it disable the player physics and attach the player to the vehicle.

tall scroll
#

Ah ok, wasnā€™t sure if this was being tested after that or not. You might get some issues there, not sure

#

Maybe share the rigid body in the inspector?

arctic sparrow
somber nacelle
# 
public void OnTriggerEnter (Collider other)
{
  var rb = other.GetComponent<Rigidbody>();
  Debug.Log($"{rb} has velocity {rb.velocity}, attempting to apply {Vector3.one * 5 * Time.fixedDeltaTime} velocity to it");
  rb.AddForce(Vector3.one*5);
}

change your OnTriggerEnter to this and show what it prints

arctic sparrow
# 
Player (UnityEngine.Rigidbody) has velocity (6.00, 0.00, 0.00), attempting to apply (0.10, 0.10, 0.10) velocity to it
somber nacelle
#

okay so notice how small that velocity you are applying is. that is likely not even enough force to overcome any friction. are you sure you want the default force mode with that AddForce call and not perhaps VelocityChange or Impulse which would not include the deltaTime calculation into it?

arctic sparrow
#

It seems to only work for a single physics step before reverting to what the velocity was before.

#

I set the power to insanely high values, and it sent the object very far, but it stopped instantly and began falling

#

And it's falling really slowly too

somber nacelle
#

then you're probably overwriting velocity somewhere

tall scroll
somber nacelle
#

at no point does that code assign to velocity

tall scroll
#

If target is 0 or small then target-current will be huge but in the wrong direction

#

So itā€™s not overwriting it but it would very quickly negate the impulse

raven basalt
#

When this is applied on the player, it causes the player to go downwards. Unfortunately, how do i prevent the player from bouncing after making contact with he floor?

    private void HandleDropping()
    {
        if (isDropping && !isGrounded)
        {
            rbody.AddForce(Vector3.down * dropForce, ForceMode.Acceleration);
            Debug.Log("Applying continuous downward force.");
        }
    }

So far I have the following:


if ( isDropping)  //This is to prevent the player from boucning off the floor when the player drops
        {
            Debug.Log("Full Friction on");
            myCollider.material = fullFriction;
            

        }

The code sometimes doesn't seem to work when the player goes downwards on a sloped floor, meaning that the player will bounce to the right or to the left

tall scroll
raven basalt
#

This is the material that was applied to it:

image.png
#

I don't think it needs any bounciness

tall scroll
#

Then set bounce combine to minimum and try that maybe

#

No garauntee but might fix it

raven basalt
#

The player still bounces even when I set the bounce combine to minimum

tall scroll
#

Iā€™m not sure then sorry

I have a float value with 4 trailing numbers e.g 0.3456. Is there a way I can remove the last two digits, without rounding?

tall scroll

Best way I know is to ((int)(x*100))/100

#

Use mathf.floor if you want to be sure thereā€™s no rounding

old linden
#

Hmm I need to maintain the .34 is the issue - I can't use rounding

knotty sun
old linden
#

Il give it a shot thanks

tall scroll
knotty sun
#

casting float to int will never round

somber nacelle
#

ah wait, that last bit would round it so ignore that part. the first part is still correct if it's just to display the value though

tall scroll
somber nacelle
#

yourFloat.ToString("F2") or $"{yourFloat:F2}"

old linden
#

Unfortunatly it needs to be correct mathematically. It's for a purchase system, so I can't have a float rounded up for sale values.
So for example, x.3456 needs to become x.34.
"F2" and "0:00" both round the value, as does Mathf.Floor

tall scroll
#

Noted and that just truncates it to 2DP?

knotty sun
tall scroll
#

Also since when does mathf.floor round?

somber nacelle
old linden
knotty sun
tall scroll
#

I guess technically it rounds but only ever down

#

It canā€™t round up

somber nacelle
#

yeah the answer would be to multiply by 100, floor it (or cast to int like steve's example), then divide the result by 100

tall scroll
#

Yeah regardless you have to do the multiply then divide bit

#

Could very easily wrap it in an extension or function for readability too

somber nacelle
#

alternatively they could just store the currency as an integer in number of cents, can't really have half a cent anyway

knotty sun
#

importantly you need to divide by 100f. Somethig Kitsuneko missed

old linden
#

I think I found a string method using "0.##" let me try it

somber nacelle
#

don't convert it to a string if this is for actual math

that should be for display purposes only

Hi do any of you work with backend php devs who send you JSON. Do you ask them to send names in PascalCase to match your Class/Property naming conventions?!

knotty sun
placid summit
knotty sun
placid summit
#

ok - so you would then just tag your classes in C# for JSON.Net etc deserializing with that name?

tall scroll
#

If you can 100% guarantee that at no point will anything accidentally change case then use whatever format you find best but the safest way with text (json at least) is usually to remove casing for keys

knotty sun
#

point is
int Score
int score
int SCORE
are all different in C#.
they are all the same in JSON

placid summit
#

well generally C# classes and properties are PascalCase, but if JSON always lowercase then fine - I just want to get most common way people handle conversion and if that is backenders sticking to lowercase and me using Json.NET tags to deserialize it's fine!

mellow sigil
#

JSON itself is case sensitive. Some parsers might not be which is why it's best to avoid keys that differ only by case

#

but that's not really relevant here

placid summit
#

Looks like System.Text.Json handles camelCase to PascalCase and Newtonsoft can be configured to and so people stick to those standards (not sure if they use all lowercase for JSON)

#

Anyone using System.Text.Json in Unty BTW?

tall scroll
#

No because newtonsoft is pretty much universally better afaik

placid summit
#

well it is easy out of the box and seems System.Text.Json use is troublesome in Unity (lots of related packages). So indeed - will stick to Newtonsoft

I got a question about Vector3.MoveTowards.
I move an object with that function towards my target position, but if there are Objects in the way towards the target, they should be pushed away. This is not the case but if I simply move my objects using the scene viewer, they do get pushed around and the physics are working in a normal way.
Is there anything similar to Vector3.MoveTowards that I could use? Or is there any way to fix this?

All it does is compute a vector.

#

How are you using the result of MoveTowards?

lilac hill
#

Elevator.transform.position = Vector3.MoveTowards(Elevator.transform.position, targetPosition, step);

The Elevator is the moving object.

#

This is in the FixedUpdate function btw

leaden ice
#

MoveTowards is NOT a thing that moves any objects in Unity

#

it's just a math function to calculate a new position

lilac hill
#

Oh

leaden ice
#

the way you're actually doing the moving of the object here is by setting Elevator.transform.position

#

That is going to bypass the physics engine entirely

#

because you're directly teleporting the Transform

#

If you want realistic physical interaction you have to move it via the Rigidbody

lilac hill
#

Ah okay, I think I get it now.

leaden ice
#

e.g.

// Calculate the new position
Vector3 newPosition = Vector3.MoveTowards(myRigidbody.position, targetPosition, step);

// Actually move via the Rigidbody
myRigidbody.MovePosition(newPosition);```
heady iris
#

The rigidbody will notice that it's in a new position in the physics update, but it won't understand that it moved to that position

lilac hill
#

This makes a lot more sense now. Thanks for the help :D

leaden ice

It moves a kinematic Rigidbody while respecting interpolation settings and physically pushing dynamic bodies out of the way properly.

dense arch
#

ooh

heady iris
#

actually, praetor, remind me how that differs from setting rb.position

#

I remember being wrong about that

#

but I don't remember in what way!

leaden ice
heady iris
#

ah, so it doesn't whack stuff in the way

leaden ice
#

it won't apply appropriate forces to things in its way, nor will it respect interpolation

#

Not a code question

dense arch
#

oh

#

what is it

#

like shaders or smth?

ok so that is weird the axis should be Z up then

swift falcon
#

both the particle and cubes use quaternion.identity

livid loom
#

oh that is weird then

swift falcon
#

the untiy version is 2020.3

#

maybe your math is wrong then Quaternion is hard to deal with

swift falcon

heres the code for instantiating one of these

livid loom
#

why not just Insatiate the object with default rotation of either the cube or the particle

swift falcon

#

Do it this way should work
csharp Instantiate(gameObject, gameObject.transform.position, gameObject.transform.rotation, parent.transform);

#

oops

swift falcon
# 
Instantiate(gameObject, gameObject.transform.position, gameObject.transform.rotation, parent.transform);
livid loom
#

I always just set up my rotations right before hand then instantiate that way personally

#

always works too

swift falcon
#

well no

        for (int z = 0; z < ChunkSize; z++) {
            for (int x = 0; x < ChunkSize; x++) {

                float noiseZ = (chunkZ * ChunkSize + z) * 0.1f;
                int height = Mathf.FloorToInt(Mathf.PerlinNoise(noiseX, noiseZ) * 10 * NoiseAmplifier);

                // Generate grass block
                Vector3 grassPosition = new Vector3(chunkX * ChunkSize + x, height, chunkZ * ChunkSize + z);
                Instantiate(GrassBlockPrefab, grassPosition, Quaternion.identity, chunk.transform);

                // Generate dirt layers
                for (int i = 1; i <= DirtLayerHeight; i++) {
                    Vector3 dirtPosition = new Vector3(chunkX * ChunkSize + x, height - i, chunkZ * ChunkSize + z);
                    Instantiate(DirtBlockPrefab, dirtPosition, Quaternion.identity, chunk.transform);
                }

                // Generate stone layers below the dirt
                for (int i = DirtLayerHeight + 1; i <= DirtLayerHeight + StoneLayerHeight; i++) {
                    Vector3 stonePosition = new Vector3(chunkX * ChunkSize + x, height - i, chunkZ * ChunkSize + z);
                    Instantiate(StoneBlockPrefab, stonePosition, Quaternion.identity, chunk.transform);
                }
            }
        }
#

heres a bigger chunk of full code

#

its not really that easy

swift falcon
livid loom
#

Yeah but I am talking about specifically how you instantiate the particle, just spawn it according to the block orientation, why not also just spawn the block the same way just use Block prefabs already set rotation so just in you rotation portion just use "blockName.transform.rotation" instead of "Quaternion.indentity"

#

that is what is messing you up it's what messing with the particle calculations

swift falcon
#

is it possible to rotate the particles themselves tho? just asking

#

OK so why I came here I am having a problem with AI aiming one projectile is like 80% accurate I am fine with that but another projectile coming from above misses by 4 meters every time.

    {
        float distance = Vector3.Distance(transform.position, target.transform.position);
        Vector3 enemyPosition = target.GetComponent<Collider>().bounds.center;
        Enemy enemy = target.GetComponent<Enemy>();

        Vector3 targetDirection = enemyPosition - startPos;
        float timeToTarget = (targetDirection.magnitude / projectileSpeed) + (distance / projectileSpeed);


        //Debug.Log("Target Velocity: " + enemyMove.velocity);
        Vector3 predictedPos = enemyPosition + (enemy.velocity * timeToTarget);

        Vector3 aimDirection = predictedPos - enemyPosition;

        return predictedPos;
    }```

I can't get my Spine animations to fire correctly. Animation names are correct but I believe I'm executing incorrectly. The NPC follows a patrol path but the walk animation isn't working right. If the player comes within a certain distance it moves towards the player. When the NPC is in attack range it should start attacking but the attack animation isn't happening.

it cannot write complex systems nor it has any logical thought to do so

LLMS do not work that way

its developing so fast maybe in 2 years it will be able to write more complex stuff

if anything jobs will increase in the amount of bad code from "AI" and systems that need to be fixed UnityChanLOL

its about Logic and problem solving

Itā€™ll be the most kitbashed answer it considers generic rather than considered code that takes into account scalability or efficiency

so you are learning a skill that spans across other fields than being a syntax writer

thats why ai makes writing code "easy" is just regurgitating valid looking syntax but the substance behind is mild at best

I'm looking to see if there's a better way I can handle this. I have a Sprite Manager that holds a public list of sprites. Whenever a game object needs to change to a different sprite, I grab the specific sprite I want by index from the Sprite Manager. This works great, but my concern is if at any point the index gets shifted a position, every single sprite that uses the Sprite Manager is going to display the wrong sprite.

I can probably get away with the system I have in place now as long as I'm careful, but I assume this is not a best practice.

leaden ice
waxen blade
# leaden ice - Why use index to identify the sprites? Where does this index come from? - Are ...

Not all of my scriptable objects need to change sprites, so instead of storing the sprite for it to change to in itself, I stored it in a manager that has all the sprites for me to access. That's the only way I know how to reference the sprite without putting it directly into the scriptable object.

The index comes directly from the game object that needs to change sprites, it's grabbing the index with a hard coded number. It calls a method on the Sprite Manager to get the sprite.

Since the project is small right now, I'm not concerned about the index changing at runtime or edit time, but I want to account for the future in case it does become a problem.

leaden ice
heady iris
#

just reference the sprite

#

Dragging a sprite into the inspector for a scriptable object does not "put it in" the object

#

you're just storing a reference

#

you're not literally copying image data into the asset

simple void
#

Hey guys, this is a stretch, but a mesh collider computes its data from a shared mesh component, and I can get the GraphicsBuffer representing the vertex and index buffer. If I edit these buffers in a compute shader how can I get the results to bake(the data needs to eventually return to the cpu I assume)

Need a little help please.
I have tried raycasting, Applying Gravity manually , however my character feet won't stay on the floor

image.png
heady iris
heady iris
#

It has a small skin width

#

this will make it slightly hover above the ground

#

Alternatively, lower the visual model a bit

wicked river
wicked river
heady iris
#

Yep.

wicked river
#

still nothing. Will try and lower the acual mesh

heady iris
#

You could also reduce the skin width on the character controller to reduce how far above the ground it sits. I'm not sure what effects that'll have though

wicked river
#

nothing

heady iris
#

what is wrong with it?

wicked river
#

before starting the level. Looks great. After starting the level Gets lifted off the ground a little

heady iris
#

it looks like your idle animation makes the feet rise a bit

heady iris
wicked river
#

sure

heady iris
#

It shouldn't look identical to the first image, notably

wicked river
heady iris
#

I need to see the character controller's outline as well

wicked river
#

ah, sorry

heady iris
#

you'll want to adjust the Center property on the controller

#

raising the entire object won't really help (that's just raising the character slightly off the ground)

wicked river
heady iris
#

I see you have a separate "Feet on Ground" component

#

what is that doing?

wicked river
#

was trying to raycast and keep the chracter grounded

#

preatty much doing nothging

#

I found the issue though

rigid island
#

dont forget about the width of the skin also adds a gap

wicked river
#

putting the player mesh into the floor and then starting seems to fix the issue

heady iris
wicked river
heady iris
#

something weird is going on here when you had the center set to 1.15:the controller is floating pretty far off the ground

image.png
wicked river
#

so I am rather curious as to why this is happening. The solution was to actual have the positoin of the model reduced by the amount it moves up

image.png
#

I'd love to figure out why this is the case.

heady iris
#

It doesn't sound like you're actually moving the character controller downwards

#

show me how you are doing gravity

#

!code

tawny elkBOT
wicked river
#

casting a ray and trying to keep the player on the floor was what I was trying

heady iris
#

Vector3 rayOrigin = transform.position + Vector3.up * (characterController.height / 2 - characterController.radius);

this is incorrect; you should be using characterController.center to figure out a point that's at the center of the capsule

#

I would suggest just doing this

# 
Vector3 moveVector;

// you do some work to compute how to move

moveVector += Vector3.down * 10f * Time.deltaTime; // add this at the end!
characterController.Move(moveVector);
#

this is not physically accurate gravity -- you just move down at 10 meters per second, constantly

#

but it's easy

#

you'd insert the commented line into wherever you're doing your movement logic currently

wicked river
#

alright. Let me give it a stab

heady iris
wicked river
heady iris
#

No.

All of the problems are with this "Feet on Ground" component

Hey ! I'm working on my game and would like that the main character play as a graffiti like this screen. What would be the best way to do it? I tought about decals first, but I'm note sure it's a good solution

I was thinking about it, but forgot to bring it up

Yup!

Though not sure if itd just be easier to use regular 2d objects for that

subtle patrol

I don't know too ^^

I just read that a solution would be to use regulard 2d objects

#

but I tought decals would be easier, even if I have some problems

sturdy kindle
#

Would anyone care to look at my script that handles this NPC animation? Animation names are correct but I think my logic is causing animations to reset or overlap somewhere. NPC should walk when patrolling and should attack when in range.

Hell you could maybe even do it in 3d and just use 2d visuals

I'll probably use 2d visuals as long as I'm not very good with decals, and I don't find the answer to my problem

You'd just need to swap out the texture the projector uses, but yea sprites will likely be easier then

I made an WebGL build for a game jam but the horizontal movement (A & D as well as a simple horizontal dash) is not working in the build (Not working in a Windows build either). Everything works fine in the editor though. Jumping and UI interactions work in the build but trying to move horizontally doesn't. I made a development windows build too but there were no errors logged in the development console either. What could cause this? (Unity 2022.3.22f1)

The movement is a simple Rigidbody.AddForce() call in the desired direction.

heady iris
#

Are you using the new input system or the old one?

#

the old one would be stuff like Input.GetAxis

torpid beacon
heady iris
#

okay, so old input system

#

a sanity check: use Debug.LogError to log one of those inputs

#

(that will make it show up in the develompent build console)

torpid beacon
heady iris
#

I wonder if this is a weird order-of-execution bug

#

Can you show me your movement code?

#

!code

tawny elkBOT
torpid beacon
#

ProcessInput() method on line 166 is where I recieve inputs.

heady iris
#

a debugger would help here

#

nothing's jumping out at me as wrong

#

assuming IsDead isn't true

torpid beacon
#

'IsDead' is false. Not really setting it to true in this project at all.

#

Since these issues don't happen in the editor, is there something I am missing that could cause issues only in builds?

heady iris
#

do you have a menu scene?

#

if so, make sure that the game works in-editor when you start there

torpid beacon
#

I do and it works starting from there in the editor

heady iris
#

(as should just restarting the editor)

#

Update methods will run in an order that depends on object creation time

#

Perhaps something else is setting the rigidbody's velocity?

#

I'd try putting an AddForce in that just applies a fixed force every frame, to see if your character moves to the side

torpid beacon
leaden ice
torpid beacon
leaden ice
#

Well those are your issues

#

According to the information you provided

torpid beacon
#

Moving left and right wasn't working in builds even though jumping and UI interactions worked fine. The quick AddForce all in the update funciton also did nothing while the player character was stationary but affected the player if I jumped and was in mid air.

leaden ice
torpid beacon
#

I made a development build and there were no errors logged in the console

leaden ice
#

there is no console for a build

#

you need to check the log file

torpid beacon
#

I will check that as well but I was refering to this development build console. Ignore the test error message

image.png
leaden ice
#

What if the TEST ERROR message is drownign out an error? Check the log.

torpid beacon
#

In the build without that Test Error, nothing was showing at all. The console doen't show up if there is nothig to log. I put that test error there so the console would display.

leaden ice
#

Next thing to do is start adding Debug.Log and make sure your forces are being added and with the correct values etc.

#

(you will read the logs in the player log)

Hello,
I'm working on a game that I'm developing with a friend. The player will play a graffiti art who can move around a 3d building.
The character will of course be animated, not static, and will be able to move around and have a fairly precise hitbox (not just a circle).
I was thinking of using unity decals, because I don't know how to manage the character when he appear half on one wall of the building, crossing to another wall. but I'm not sure that's the best idea. How would you have done it?

shy dune
#

i have a script that bakes occlusion data into texture and saves it to file,
i wanted to automatically assign this texture to shader but i can't find a way to do it, i want to set it as a reference to file like you normally would by drag and dropping, except automatically, any ideas?

heady iris
#

you mean you want to assign it to a material?

shy dune
heady iris
#

you need to use SetTexture

shy dune
#

SetTexture only allows me to set it to a texture variable, i want to set it to file, in editor, not runtime

heady iris
#

You can't "set it to a file"

#

but you can certainly assign a reference to an asset!

#

it's an important distinction: a random jpeg you have lying around on your computer won't work

#

it has to be imported and turned into an asset

#

but it sounds like that is the case

shy dune
#

yes it is an asset

heady iris
#

I'm pretty sure the process is the same as changing the texture at runtime

cosmic rain
shy dune
#

i have multiple materials that use the same texture

cosmic rain
#

Then automate it. But that doesn't change the fact that you need to import the texture for it to be usable.

heady iris
#

i think the texture is indeed being imported already

heady iris
#

and actually -- once you've got the texture asset, you can overwrite it with a new image and unity will just re-import it

#

so you won't need to do any additional work

cosmic rain
#

You'd need to move the file into the asset folder before that though.

shy dune
shy dune
heady iris
#

ah, I suppose you'd need that if you wanted to immediately import the image

Need a sanity check. I'm wanting to display a non-serialized property value in the inspector for debugging. I know Unity wont display them even in Debug mode. It also seems impossible to do with a custom property drawer due to (Type)SerializedObject.targetObject returning the class implementing the property, rather than the drawer's target class. Am I overlooking something simple?

#

You're starting a coroutine that lasts more than one frame every frame?

dense estuary
#

How else can I make the coroutine run constantly?

leaden ice
#

start it in Start and give it an infinite while loop

#

if you start this every frame you're going to have many of them runing simultaneously

#

is that intentional?

dense estuary
#

Yes

leaden ice
#

Ok so maybe I don't really understand what this coroutine is doing

tranquil rover
leaden ice
#

why is it an OverlapCapsule and not an OverlapSphere?

dense estuary
#

If the player is on higher ground than the object, it may not be detected

leaden ice
#

i see so the circular cross-section of the capsule is a flat circle

#

and that's the radar

dense estuary
#

Yep

leaden ice
#

Ok I think I see the problem here

#

Or at least, one problem

#

If you have multiple hits then this is going to blink them one by one in series

#

rather than all at once

rose willow
#

why is it that when I build my project the lights don't work?

dense estuary
dense estuary
leaden ice
#

what you want to do is like:

Physics.OverlapCapsuleAll(results);
List<Transform> correctAngleResults = new(); // really you can resuse this list for efficiency

for (int i = 0; i < hits; i++) {
  // blah blah ray angle stuff:
  if (Mathf.Abs(colliderAngle - rayAngle) <= 5f) correctAngleResults.Add(results[i]);

  if (correctAngleResults.Count > 0) { // If we saw any hits
     while (time < duration)
     {
        foreach (var result in correctAngleResults) {
           result.GetComponent<IMage>.color = Color.Lerp(startColor, endColor, time / duration);
        }
        time += Time.deltaTime;
        yield return null;
     }
   }
}```
#

this will blip all the results simultaneously

#

(obviously pseudocode and missing stuff)

#

Anyway in this code:
https://hastebin.com/share/wuwifujiqo.java

You probably want to remove the yield return null; on line 38 as well

Hastebin

Hastebin is a free web-based pastebin service for storing and sharing text and code snippets with anyone. Get started now.

#

since it doesn't do anything right now

#

other than add extra "dead" frames to your coroutine

#

for no reason

#

i.e. it's going to wait a frame for every object in the overlapcapsule, including those you aren't doing a "blip" for

#

The other thing you might want to do is increase the fade in speed when the thing is moving faster

dense estuary
#

There is no fade in speed

#

It becomes visible immediately, then fades out

leaden ice
#

Also this:

if (Mathf.Abs(colliderAngle - rayAngle) <= 5f)``` since it's not a fixed framerate it may end up missing things.
dense estuary
#

I believe that is what's happening currently. That's what I am trying to fix

leaden ice
#

Can you show the Update code? I think you must have something that is saying like "if there's a coroutine happening already, don't start one"

#

because what I'm seeing right now is that the new blip isn't happening until the old one fades away completely

dense estuary
leaden ice
#

so maybe what I mean is increase the fade-out speed

#

yeah I think the problem is that you have multiple coroutiones at once

#

showing a blip for the same dot

#

and therefore fighting over the alpha for that dot

#

and the older one is winning, so you see it as dim when it should be bright

#

the main fix for that is just increasing the fadeout speed

#

or making the subsequent "blips" for the same object happen on separate objects

#

basically it's taking longer than a full rotation for the blip to fade out, so it's still in the process of fading out by the time the line comes around

rich leaf
#

hey i have this variable

    public int currentState

that is public bc it will be accessed in other scripts. I want to make an event that gets invoked whenever this changes, how can I do this?

leaden ice
rich leaf
#

to subscribe to that event what is the signature?

leaden ice
#

Note that we have switched to a private backing field here called _currentState instead of the public field.

#

Action<int>

#

which is any function that returns void and has a single int parameter

#

e.g.

void Example(int param) {
  //whatever
}```
#

You could also define a custom delegate if you want

rich leaf
#

And when i want to change this value, I still can just do things like currentState = 5 for example?

leaden ice
#

CurrentState = 5;

#

since that's the name of the property

so the private variable is just to store the value of the property?

leaden ice
#

yes that's the actual field where the data is actually stored.

#

Ok let me quickly try this

#

thnx

#

Seems to work, thanks! Is there a convention for the naming of properties?

#

ie currentState vs CurrentState?

leaden ice
#

Unfortunately there are two separate conventions šŸ˜¦

#

There's the Microsoft C# convention

#

and there's the Unity convention

you wouldn't "calculate" a ratio you'd just choose one

# 
float ratio = 0.5f;

float blipFadeSpeed = spinSpeed * ratio;```
#

simple example, made up number that might not be sensical^

dense estuary
#

So something like this? cs float ratio = 2 / baseScanSpeed; float desiredDuration = scanSpeed * ratio;

#

if the baseScanSpeed is 45, and the scanSpeed is 45, this results in the duration being two seconds.

#

But if the scanSpeed is 90, its only 1 second.

#

Oh

#

wait, that does the opposite

#

90 * 2/45 is 4 not 1.

leaden ice
#

I don't really see why the ratio should be based on the base scan speed

#

just pick a number

#

If that's not good enough you can just use a remap function

dense estuary
#

My issue was that I needed inverse proportionality.

hey yall, i was wondering how I should go about getting a list of sets of variables in the inspector.
my first approach was to just define a smaller class in the script, with the only members being a few variables that the inspector serializes.
That method only serializes the field to drop an instance of that class in, instead of allowing me to input all the variables each list item would have.
The other method I looked into was using dictionaries, but those do not serialize at all so that won't work.
Of course, I could always just make a list for each data point but it would be more organized and easier for me to get the inspector to work like I want because this script will be used for countless objects, each with different values.

Below is my code and the inspector field it causes

        Vector3 newRotation = transform.eulerAngles;
        newRotation.y = Mathf.SmoothDampAngle(newRotation.y, _rotationTarget, ref _smoothDampRotation, _turnTime, float.PositiveInfinity, Time.smoothDeltaTime);

I have 2 objects. I need to align the object with the "tail" (the long cube with the 2 spheres in each extreme), so that it aligns with the (mostly) cylindrical object's forward and up vectors (the pyramid indicates that object's upwards vector).

I came up with this code (this script attached to the object with the tail):

private void AlignStem()
{
    transform.rotation = _previousRotation;

    Vector3 dir = (transform.position - _stemInfPoint.position).normalized; // <--- _stemInfPoint is the bottom sphere's transform

    Vector3 yProjection = Vector3.ProjectOnPlane(dir, _basePlate.up); // <--- _basePlate is the cylindrical object
    float yAngle = Vector3.SignedAngle(-yProjection, _basePlate.forward, _basePlate.up);

    Vector3 zProjection = Vector3.ProjectOnPlane(dir, _basePlate.forward);
    float zAngle = Vector3.SignedAngle(zProjection, _basePlate.up, _basePlate.forward);
    
    transform.Rotate(_basePlate.up, yAngle, Space.World);
    transform.Rotate(_basePlate.forward, zAngle, Space.World);
}

The problem with this is that it produces the result of the second 3rd row of pictures, and I don't understand why.
Any ideas where I could be failing?

Edit: don't guide yourself by the pivot point axes shown in the las picture. I need to align this with the information provided (the tail points, and some directions).

How do I make a test show up as an editor test? The default script generated by "Create an Editor Test" only shows up under "PlayMode" (this is with an essembly created through "Create Test Folder"). If I disable all platforms except editor it doesn't even show up under PlayMode anymore.

Running Unity 6000.0.0b16, is it just bugged on that version maybe? Or am I missing anything?

    // `yield return null;` to skip a frame.

Hi guys, I was thinking about how to make the world selection menu in the MainMenu scene pass the name of the world to the gamecontroller in the Game scene

#

I thought that traversing between scenes doesn't reset static values (If you didn't reset it in any code) right?

somber nacelle
#

it does not

pastel patio
#

Is it a good idea to simply set the currentWorld value (Static) in the gamecontroller?

somber nacelle
#

that is definitely one way to pass data between scenes. or you can use a DDOL object that holds the data you need, there's also the option of using a ScriptableObject for it as well, you just have to be aware of how they work and make sure you are properly resetting the values for it because changes to SO assets in the editor persist

pastel patio
#

If there're no consequences in using a static value it looks like 100% top option, I don't want to make things complex for no reason '^^

#

I'm only trying to pass the world name, the save files are too big to be worth passing anyway, they're just loaded from the files

Hey guys! My rigidbody object changes from dynamic to Kinematic whenever I play the game. It's a network object and I'm using unity 6.

Could be an intentional quirk of how networked Rigidbodies work, or perhaps the authoritative version of the body is kinematic by whichever host owns it

it's a bit awkward, if you want different behaviour or objects that change their kinematic flag during the game, you have to work around it

somber nacelle
# versed spade https://gdl.space/asahurosew.cpp For some reason my rotation from my target obje...

there are two reasons for this. for one, transform.rotation is a quaternion, this is a normalized 4 axis data type used to represent a rotation (basically a normalized Vector4). what you see in the inspector are the typical euler angles you are familiar with and are expressed as a Vector3, one float for each axis.
you should also note that the values provided by the eulerAngles property and the values in the inspector can also differ due to the number of ways any given rotation can be expressed in euler angles and the fact that those values are interpreted from the quaternion at the time they are accessed

versed spade
#

How do I avoid it getting interpreted as a quaternion then?

somber nacelle
#

read what i said again then look at lines 29 and 30 in your code

#

also there is no "getting interpreted as a quaternion". the rotations are quaternions, and when you access the eulerAngles (or view the inspector) you are seeing the euler angle values that were interpreted from the quaternion

paper flame
#

anyway to prevent jitter with network transform and photon

versed spade
#

Sorry I am reading back over what you are saying and am still unsure of what I am meant to do. I can't find any other way to access/change recttransform rotation besides this euler method, if I am even meant to use a different one. and if its the same, I still have no clue how to adjust it to fix this.

somber nacelle
#

think about it, you are trying to use Quaternion.Euler, which expects you to pass euler angles to it. The euler angles can be accessed through the rotation's eulerAngles property or the transform's eulerAngles property. However you are just using a raw quaternion value. So you need to either not be using Quaternion.Euler and just assign directly to the rotation using a quaternion that represents the desired rotation, or you need to be passing euler angles to Quaternion.Euler

#

also keep in mind that your current code isn't even getting the direction from one object to the other, you're just using the target object's rotation for whatever reason

versed spade
#

I got it! thx. I'll look more into quaternions in a bit. definitely need to review that šŸ˜…

tall scroll
#

Could also be radians vs degrees if thatā€™s not been mentioned yet

somber nacelle
#

why would that have been relevant when their code was

Debug.Log("Target rotation Y: " + targetObjectTransform.rotation.y);
uiElement.rotation = Quaternion.Euler(0, targetObjectTransform.rotation.y, 0);

and expecting euler angles in the log

tall scroll
#

Hmm for some reason I had it in my head that quaternions were in radians but theyā€™re just funky lil things that are seperate

somber nacelle
#

yeah, you can use radians to calculate the values for their axes, but the values aren't radians themselves

Trying to get a rotation system working for a VR controller's Mouse Fallback when no VR is connected. Basically, a way that you can rotate an object when you don't have a VR controller connected. The idea is that while you're carrying something, you can middle click to go into "Rotate mode" where the mouse movement rotates the object in place about your grab point, rather than moving it. The issue is, I can't see any way to get the Hand component to stop listening for input but still keep holding the object.

Current idea: Lock the mouse cursor so it doesn't move while you rotate the object.
Follow up problem: Locking the cursor always brings the object to the center of the screen so you can't rotate it in place.
Attempted fix: cache the position when you start the lock, move the attach point to that position at the start of next frame.
Follow up problem to the fix for the follow up problem: When you release, the object is now very far offset from your mouse position.

I need a way to let the mouse movement control the object's rotation when it's isInRotateMode is true, and not move. If anyone knows how I can achieve that, or a fix for the follow-up to the fix to the follow-up, I'd appreciate it.

Hi! trying to disable domain reload and wrote a script to find all MonoBehaviour to reset their static fields, but the GetEnumerableOfType returns an empty collection (.Where() filters everything out of the search). If you have any tips :

public class ReloadDomainStaticFix
{
    [InitializeOnEnterPlayMode]
    static void OnEnterPlaymodeInEditor(EnterPlayModeOptions options)
    {
        Debug.Log("Reloading statics");

    static void ResetStaticsOnEnterPlaymode<T>() where T : class
    {
        foreach (var item in GetEnumerableOfType<T>())
        {
            foreach (var field in item.GetFields(BindingFlags.Static | BindingFlags.Public | BindingFlags.NonPublic))
            {
                // Check if field type is a value type
                if (field.FieldType.IsValueType)
                {
                    // Set field to default value for value types
                    object defaultValue = Activator.CreateInstance(field.FieldType);
                    field.SetValue(null, defaultValue);
                }
                else
                {
                    // Resetting field to null for reference types
                    field.SetValue(null, null);
                }

Would somebody be so kind to help me with calculating coordinates for drawing a part of a circle?

I have a function that returns N points for a part of a given orbit (assumed to be circle) that intersects the radius of the visibility. Currently the function is correctly determines when the orbit is fully inside or outside of the visibility (Meaning, when to either not render the orbit and when to just render a circle), but I can't make the partial part to work. I can see that it finds intersection points correctly, but I can't wrestle it to interpolate a correct arc between them.

https://pastebin.com/i9DbBrKa

This is the current code, and this is what it results in (screenshot from Unity, it just takes the list of coordinates the function outputs and draws a straight line from one point to the next, black circle represents the visibility radius).
In particularly, the issue, I suspect, is with these calculations:


                    float startPointAngle = Vector3.SignedAngle(Vector3.left, beginPoint, Vector3.down);
                    float endPointAngle = Vector3.SignedAngle(Vector3.left, endPoint, Vector3.down);
 
                    //angle of the visible arc
                    float angleA = Mathf.Min((2 * Mathf.PI) - Mathf.Abs(startPointAngle - endPointAngle), Mathf.Abs(startPointAngle - endPointAngle));
 
                    //from where to begin iterating arc
                    float startAngleRadian = Mathf.Min(startPointAngle, endPointAngle).WrapAngle() * Mathf.Deg2Rad;

I'll describe exactly what I'd like:

I'd like to create an action creation system that allows players to customise all the powers/attacks and other actions they do.

To do this, I'd need a window that opens when you right-click on a square in my action bar, in this window you'll find each brick that will allow you to create the action.
example :

  1. The type of weapon, in this case, a magician's glove
  2. The type of spell, in this case, a spell that affects 2 people
  3. The type of damage, in this case, a freezing spell

Cost :

  1. 50 mana
  2. 50 life
  3. -5m range

Example 2:

  1. The type of weapon, in this case, a two-handed axe
  2. The type of attack , in this case, a simple attack
  3. The damage modifier, here, say level 40 (So double the damage for level 40 weapons)
  4. The effect, in this case bleeding, which creates damage per second of bleeding.

Cost :

  1. 100 of stamina
  2. 20 life

Obviously, all choices such as the type of weapon, attack/spell, effect or even cost are chosen by the player, who can very well decide to use only his life or stamina for his action.

Here's what I'd like to create as a mechanic for my game

leaden ice
#

I mean this is all a very complicated system

#

but it's really unclear what you're asking here

#

are you just asking how to make this UI?

#

Or are you actually asking about this whole ability system and everything that goes along with it

#

because those are two separate questions

#

and two separate things that need to be built, and interact with each other

fleet tide
leaden ice
#

This isn't something you just "find a tutorial" for

#

do you think game devs just find tutorials for every mechanic in their games?

#

This is a very complex and bespoke system for your game in particular

#

Tutorials are there to help you learn the basics

#

From there you are meant to go off and build your own things

#

Start by designing a data model that adequately captures all of this stuff

#

then you can figure out how to make a UI that builds these things

fleet tide
#

I know, it's just maybe some people knows unity much better and could help me to know better how to implement this

#

create a UI, and a event for have a windows for it, i can do it but for have the rest, its very particular and i never see anything for help me

#

i'm beginner so learn all unity and all C# it's not my goal^^'

leaden ice

And if you don't know C# very well

#

you're going to struggle A LOT

        }
        else
        {
            bulletHole = defaultBulletHole;
        }

        GameObject spawnedObject =  bulletHole.Spawn(hitArgs.HitPoint, Quaternion.LookRotation(hitArgs.Normal, Vector3.up) * Quaternion.Euler(0f, 0f, 0f));
        if (spawnedObject != null)
        {
            spawnedObject.transform.parent = hitArgs.Collider.gameObject.transform;
        }
    }

and put that on a script on the surface

#

then your code can just be like:

var surfaceInfo = hitArgs.SurfaceInfo;
Instantiate(surfaceInfo.bulletHolePrefab);```

# fleet tide I'll describe exactly what I'd like: I'd like to create an action creation sys...

I'm sorry. For some reason I haven't received a notification for your message.
Honestly, I don't think it's a very complicated system as PraetorBlue has previously mentioned. You should be able to do this if you know how to code and create UI on an intermediate level.

    1. Create a script for all this system. Let's call is InventoryManager.cs?
    1. Create a Button, which activates an Inventory Window when pressed
    1. The Inventory Window should contain the 3 or more desired sections. In your case, for the weapons, spells and types of the damage. How you arrange them is up to you.
    1. Every section should usually contain a Layout Group, which makes it more comfortable for you to arrange the items inside of it.
    1. The script, if needed, should contain a reference to each Layout Group. This way, you may be able to instantiate the desired items from the list, if needed.
    1. You may have a ScriptableObject for your items, which tells you about their cost and type, which might be an enum. For example, you might have a type = ItemType.Weapon with cost = 50, where your code then checks its type and converts it to mana, in this case.
    1. Every item should have a Button, which tells your script when clicked. Your script checks for the item being available, shows e.g. the "Confirm your purchase" window, reduces the player's balance, and adds the item to the list of your current items. Should, actually, be a struct with a List for each of your weapon types.
    1. The script checks for the current items used, then adds the suitable modifiers.

hello, im trying to but cant figure out how do i replace the loadnextlevel function to work but without the +1 build index (i use it as a on click on the button), i want to replace the +1 with a string so i can type the name of the scene the button will go to

leaden ice
#

the inspector?

sharp bison
#

yea

leaden ice
#

just make a variable for that.

public string sceneName;```
#

and use that

#

alternatively you can have the button ONCLick pass a string in. In which case you would give LoadNextLevel a string parameter.

sharp bison
#

okay ill try but what about the +1 build index will that get ignored?

leaden ice
#

you would get rid of all of that

#

naturally

#

And use the scene name instead
SceneManager.LoadScene(sceneName);

sharp bison
#

oooh thank you

#

ooh but i forgot to say the tricky part, i also want to start a coroutine for the load level ienumerator, its basically a transition

leaden ice
#

I don't see how that's tricky

#

you're literally already doing it

sharp bison
#

can i just type StartCoroutine(LoadLevel(SceneManager.LoadScene(sceneName);

leaden ice
#

Of course not

#

Why are you trying to change a bunch of random other things?

#

as mentioned you would remove the levelIndex parameter and the parameter you pass into the coroutine

#

or add the string as a parameter instead

sharp bison
#

if i just type csSceneManager.LoadScene(sceneName) and add the public string it will just immediatelly go to the scene and not activate the ienumerator i need to wait for the fade in animation to play, i need like a way to also keep the startcoroutine(loadlevel but still have it so i can type the name in the onclick()

leaden ice
sharp bison
#

sorry i didnt understand

leaden ice
sharp bison
#

how should i do that? im not that experienced in coding sorry

# 
public void LoadNextLevel()
{
    SceneManager.LoadScene(sceneName);
    StartCoroutine(LoadLevel);
}
#

i tried like this but got this error : Argument 1: cannot convert from 'method group' to 'string

#

ooh i got it

Subtitle system.

for this would i need to create a system to match the text version of voice lines with the audio versions and make sure that it takes the same amount of time to type out the text as it takes to say the lines?

i did this and it worked thanks for the help

so basically not load scene but loadlevel and replace the int with string

NullReferenceException is an extremely common error and it means your code is trying to use a reference that has not been properly assigned

I made a movement script a while ago and am now experiencing a problem that only occurs when I change Time.timeScale. I'm changing the timeScale to 0 for pausing. If I jump, then pause during the delay coroutin, when I unpause, I can nolonger jump. I think that setting the timeScale to 0 is causing the coroutine to stop in its tracks and not reenable jumping. Here is my code for the jumping: cs public void Jump(InputAction.CallbackContext Context) { if (Context.performed && IsGrounded() && canJump) { rb.AddForce(new Vector3(0, jumpForce, 0), ForceMode.Impulse); canJump = false; StartCoroutine(Delay()); } } IEnumerator Delay() { yield return new WaitForSecondsRealtime(jumpDelay); canJump = true; }

Was the component disabled? Had the object become inactive? Did the coroutine ever start?

Show your updated test code for the coroutine

when jumping, pausing, then unpausing, it does not print the second log.

#

Unscaled time isn't supposed to be affected by time scale so you may need to elaborate what "pause" refers to.

I tried using unscaled time on the waitForSeconds to see if that would fix the problem, it did not.

Escape will also unfocus the game when in the Editor.

The only thing you need to use it for is to know which way the bullet hole should be oriented. You could even just set like the transform.forward to be the normal of what was hit. Though this depends which way your object is facing

Is there an easy way to add GUID to a SO without writing custom editor code and what not?
I just want to to generate unique ID to be used for saving/loading SO data(GUID would act as an index for my Dictionary)

#

I tried both Guid(System) and GUID(Unity) and none of them work.
At least Unity one shows in the inspector, but I can't give it any value(only variable name appears)

cosmic rain
#

Wdym by "give it any value"?

upper pilot
#

I can't type anything in the inspector because there is no text field attached to GUID

#

I found one solution that broguht me closer and might even be enough.

public string UID;
        private void OnValidate()
        {
        #if UNITY_EDITOR
            if (UID == "")
            {
                UID = GUID.Generate().ToString();
                UnityEditor.EditorUtility.SetDirty(this);
            }
        #endif
        }
dusk apex
#

Changing the public string won't reflect on the actual GUID in the meta file though

upper pilot
#

So is the above still not enough?

dusk apex
#

Unless you have an else there that modifies the meta file as well

dusk apex
upper pilot
#

As long as the GUID doesnt change, its good enough right?

#

At least it shouldnt change

#

Everywhere I find something, its either huge script or a simple script like the above.
I am only worried that it wont work when the game is compiled.

cosmic rain
#

Why not just assign an incrementing int id? Do you really need 128 bit entry to identify the object?

upper pilot
#

I just need it to be unique.

#

How do I keep track of last ID value tho?

cosmic rain
#

Well, it's gonna be unique if you make it unique

upper pilot
#

If I delete a SO file, I cant reset ID value, since each unique item should have its own unique ID forever.(or until I dont care about save compatibility then its fine to "Reset" IDs)

cosmic rain
upper pilot
#

So where do I store global ID value so it's always unique?

#

I am confused

#

How do I make sure its unique and never repeats?

crystal herald
#

My character can release wind (particle system) from his hand and I want to make this wind spin game object which I called "Pinwheel", but I don't how to do it. Does anyone know how to solve this problem?

upper pilot
#

Where do I store that information

cosmic rain
upper pilot
#

I dont know what are my options

cosmic rain
#

Where were you planning to have the dictionary?

upper pilot
#

in my game loader that is runtime.

lean sail
upper pilot
#

But I dont want to assign new value each time, also it has to remember old ID's(from removed SO files)

#

so I have to manually asssign ID to my SO?

#

I need a more automated way.

lean sail
cosmic rain
#

Have an "MyItemManager" SO that contains an array that would reference each instance of your so that ever existed.

#

Then the IDs of each of your SOs would just be an index into that array

lean sail
#

Why does it need to remember IDs from deleted SO's?

upper pilot
#

Then this MyItemManager needs to always update when I add new SO right?

#

Because I use ID's to save the data, so I can later load specific SO data by Id

cosmic rain
upper pilot
#

If I remove item in the middle of my list, then all items will shift.(unless they have unique ID/GUID then I can make sure they stay unique)

upper pilot
#

This is automated

cosmic rain
#

Instead of removing, you can set the reference to null

upper pilot
#

It already gives me ID as a string

cosmic rain
upper pilot
#

Resource.Load can just read it and assign it at runtime into a dictionary or even List of Tuples I think(if that makes it any better)
Then my Save system can check if saved GUID exists in the database.

cosmic rain
#

It's like keeping an industrial refrigerator in your home to store a bottle of beer

upper pilot
#

But it doesnt require inventoryManagerSO and making sure that new item SO will update that manager.(which I dont know how to do)

hard sparrow
#

JsonUtility.ToJson(myClass) is writing empty (I check right before and see the class is not null and contains data). It's a regular class, no monobehaviour. Intended?

cosmic rain
upper pilot
#

Yes, but that simple int requires new scripts and I need to make sure the int stays unique + figure out a way to notify managerSO that a new SO was created.
Then I have to apply it to all SO types(not just items)

cosmic rain
upper pilot
#

That last part(notifying SO Manager that a new SO was created) is where I am stuck.

#

How else would a save system store SO reference?

cosmic rain
#

Just use static events

# 
public static event Action<param> NewInstanceCreated;
hard sparrow
#

I use static events for everything. Has yet to cause issues

#

for everything observer pattern related, I mean

upper pilot
#

Do those work in editor? I have too little experience with Editor scripting

cosmic rain
cosmic rain
upper pilot
#

Interesting, I will try that then, but I might as well create baseSO class since I need most SOs to be saved

#

and 1 generic Manager to store all Id's/references I guess

Hey guys - let me know if I'm posting this in the wrong place. I am doing a video tutorial, and I'm having trouble with the Unity extension in VSCode. A lot of the features that the instructor is going over in this lesson about how to autopopulate things in VSCode with the Unity extension are not working at all, and I'm getting very bizarre behavior. My hunch is that there's a weird interaction with the .Net Install Tool, C#, C# Dev Kit extensions. All three of these are required to run the extension, and nothing else is enabled.

#

Can provide a lot more context but let me know if this is the right place, would really appreciate any help

Visual Studio Code guide

If your IDE is not underlining errors in red or autocompleting code,
please configure it using the link below:

https://on.unity.com/vscode

spring creek
#

You need c# dev kit and unity extensions.
You need an up to date package in unity
You need to set vs code as the external tool.

#

Also, if the sdk is not installed by the c# dev kit properly, you have to do that manually

real swallow
#

Okay thank you, pretty sure these are good but let me double checke everything now

#

Okay, so the first three are good, but I'm not sure about the C# dev kit being installed properly. I have some chatgpt instructions I could try, but do you have any guides you recommend for the last step?

If it helps diagnose the problem, the color formatting starts off correct based on the video, but then switches after 2-3 seconds of re-opening VSCode to this screenshot (normally these are green and purple)

If you want to go the easy way about it. I'd just make an animation in blender

Who said any of that is flexable

I see two uses, both are different animations

barren sigil
latent latch
#

could be some blendshape stuff going on

#

I just don't feel like it's a full physics solution. It's a mix of animation + tricks to make it seem like it.

#

blendshape / IK / weights is where I'd start

#

or, if you just want to brute force it all. Just make a handful of different shape variations and do animations independently.

Just confirming something because I assumed this wasn't true, classes can touch their own private variables even if it's in a different instance of the class?

public bool IsInstanced { get; private set; }

public virtual Task Create(Creature creature)
{
    Task instancedTask = (Task)ScriptableObject.CreateInstance(GetType());
    instancedTask.name = "Instanced" + name;
    instancedTask.taskDescription = taskDescription;
    instancedTask.creature = creature;
    instancedTask.IsInstanced = true;

    return (instancedTask);
}

was suprised this wasn't throwing an error

somber nacelle

yes, private means that only objects of that type can use it (or nested types). it does not mean only that instance can access it

We just set up gamepad support with unity input system, and for some reason it seems to be polling much slower than Update (specifically for gamepad, mkb is smooth), and also only on my machine, not on other developer's machine. Has anyone experienced this before?

quartz folio
unreal temple
#

(and for clarity: yes, it works fine in other games)

unreal temple
#

I don't know about delta time, I don't think there's any time-based stuff in the input. We're just reading inputs every frame (checked by logging framecount on read) and many are missed. Like buttons go down and then up, and no release is registered.

#

Okay, so the situations becomes worse over time, and presently it's not happening so the video will not look very exciting. Bascially it looks like it's polling at 30fps instead of ~100 like mouse.

#

But at times it dips down to <10fps and that's when it drops inputs

#

I'll try to get a nice repro video a bit more

quartz folio
#

I would reiterate to check the input debugger too

unreal temple
#

Not entirely sure what you mean about the set up, if you mean code or the settings menu, but I'll try to get a vid for context first.

could generating a random number every frame lead to different results for each player in a multiplayer game?

#

If im using the same seed for the number generation it should give the same results but since the fps could drop at any time that could lead to different results right?

somber nacelle
#

if each player is generating their own random numbers rather than having one authority providing the random numbers to each player then yes that is a possibility. especially if they may generate a different amount of numbers

dawn nebula
#

How, freaking, ever.

#

That is a dumb way to do it.

somber nacelle
#

right but if they are generating a number every frame, then someone with a lower framerate will have generated fewer numbers than someone with a higher framerate

#

and they have to guarantee that each player is generating the numbers in the same exact order

dawn nebula
somber nacelle
#

right which was the point of my answer

swift falcon
#

so lets say the game is locked to 60 fps, now if they generate a random number in only 1 of those frames, it should be the same number for everyone?

#

because i dont know if it can go to 0 fps

#

in any case it would lead to different results i think

somber nacelle
#

if you want to guarantee that all players are seeing the exact same results, then you should be using some central authority that tells all of the players what they should be seeing

swift falcon
#

like the server generating those numbers and sending the players that data

somber nacelle
#

yes, or the players verifying with the server that they have generated the expected result

swift falcon
#

alr, thanks šŸ‘

For some reason, setting the rb.rotation does not always work when the agent and rb are on the same GO. Is this intended? Ive managed to isolate this issue to this exact case. If the agent is on a child object it seems fine. The collider has no friction, isnt colliding with anything other than the floor, movement also seems perfectly fine. The agent will start rotating fine but then just suddenly pauses, then eventually continues again. This is the test code which can replicate it https://gdl.space/hajapatabo.cs
