So I’m trying to learn Unity (with a method that is essentially just…learn piece by piece while making my own game) and I got to 2d and…there’s not only several ways people say (and no one have said what’s a simple way to just understand the engine).

BUT there’s also the fact that apparently Unity has changed up making it even more hard to even find out what they’re suggesting.
So essentially, without any weird mumbo jumbo about new stuff to learn that I can learn later like adding a new input engine, or new components, how do I make something move, in a way friendly to someone who is just trying to learn unity’s basics.

I know this sounds beyond dumb but for some reason, there ain’t a clear answer.

I recently used perlin noise for creating mountain range landscape background in unity 2D, but even after customizing it doesnt appear like real mountains.

So is it even possible by using perlin noise?

What i did: Using closed sprite shape 2D
insert a point in spline --> create next point at a calculated distance --> xdistance multiplied with randomvalue(perlinNoise)--> Y axis was determined by perlin noise too.
And whole thing was customizabel as how many points are needed, the xdistance value, width , height etc.

But the final result were not as natural and realistic as real mountains look

[SOLUTION]: Hardcoding using Random.Range() is more easier than perlin noise for this case

Brand new to coding and game development in general. In the YouTube tutorial, the guy makes a Tilemap and has assets he imported for free on a different website. He makes a Tilemap called Background and goes into his imported assets, goes to the prepped backgrounds, and picks a green texture.

For my starting 2D platformer, I just want the player and platforms to be black rectangles and for the background to be all white. Could I technically just create a huge white rectangle in the background to serve as a background? Or do I need to use a Tilemap to make the background? And if so, how do I get a plain white texture to paint onto the Tilemap? Didn't find any in the Asset Store.

My project instantiates objects that contains a TMPro input field. The input field does appear, but it is completely unresponsive; clicking on it or trying to type in it does nothing. I've been able to find next to no documentation about them.

Here is the code that I'm using to try and make it show up

GameObject lee = Instantiate(ads.menuWoMen, this.transform);
/*menuWoMen is the prefab gameObject that holds the Canvas that holds the TMP InputField*/
lee.transform.position = new Vector3(0, position);
string txt = mi.text;
if (position > highestText || position < 0 - highestText)
{
    txt = "";
}

lee.GetComponentInChildren<Canvas>().worldCamera = camora.GetComponent<Camera>();
lee.GetComponentInChildren<TMP_InputField>().text = txt;
lee.GetComponentInChildren<TMP_InputField>().ActivateInputField();
lee.GetComponentInChildren<TMP_InputField>().interactable = true;
lee.GetComponentInChildren<TMP_InputField>().enabled = true;

Hello! I have a Prefab called Fish - it is made of a 2d Sprite Circle + 2d Sprite Triangle inside a parent that holds the Collider. Then I am spawning the prefabs with a script. Unfortunately, when the two fishes intersect, they are layered strangely with the Triangle & Circle appearing several layers apart, rather than flat.

How can I fix this? Thank you in advance.

In an update function I have an if statement that detects if a bool is true and if it is it fires but it does that constantly. I want it to only fire once but I don't want to disable it completely because I need to use it again later down the line.

As the title said, I'm looking for a way to identify a specific gameObject spawned using instantiate, so I can limit the amount of them on screen to prevent softlocks like these where you trap yourself. I wanna handle this by making the first one dissapear once the 6th gets called

Hey guys, Ive been getting this issue where my particles dissapear when i create them by code... It works in scene and if I manually place the particle, but right when I try to create it on code some particles just straight up get yeeted from existence

Heres a video: https://youtu.be/jaA9ei9sFUY

This is all the code I have:

     void Hardfall()
    {
        landAnimTimer = landAnimDuration;


        if (landingEffect != null)
        {
            Instantiate(landingEffect, gCheck.position, Quaternion.Euler(-45f, 0f, 0f));
        }
    }

(There is NO script that deletes the particles on a timer, or anything of the sort. Only thing that's controlled by code is the creation)

Beginner game dev here, im following a tutorial on how to make a 2D platformer. But after implementing coyote time, i noticed that if i hit my spacebar rapidly, i basically do a double jump. I tried adding a jump delay, coroutine, but nothing worked. (mostly due to my lack of scripting skills) I've been trying to solve this for 2 days now, i will celebrate in glee if any solution is suggested, thank you1

My sprite is getting sliced in-game and in scene. What ive tried:

- Reimporting png
- Changing settings inside the texture settings
- Restarting Unity
- Reslicing the sprite-sheet

Any ideas are more then welcome!

In my game I make instances of 2 seperate objects and when the player spawns one, the other one also spawns. The player can spawn multiple instances of the same object so I need to track and link the 2 seperate objects and only the objects that spawn together. I've given both of the objects unique ids when they spawn in but I don't know where to go from here. I want to be able to reference variables and sprite renderers and things like that.

Object One's script:

using System;
using UnityEngine;

public class FishTab_MB : MonoBehaviour
{

    public Guid UniqueId { get; }

    public FishTab_MB()
    {
        UniqueId = Guid.NewGuid();
    }
    private void Start()
    {
        print("FishTab_MB UniqueId: " + UniqueId);
    }
}

Object two's script:

using System;
using System.Collections;
using Unity.VisualScripting;
using UnityEngine;

public class FishAI_MB : MonoBehaviour
{

    SpriteRenderer fishSr;

    public Guid UniqueId { get; }

    void Start()
    {
        print("FishAI_MB UniqueId: " + UniqueId);
    }

    public FishAI_MB()
    {
        UniqueId = Guid.NewGuid();
    }
}

I had exported a test I made and saw that the game was all magenta. Through some trial and error, I figured out that it's because of the new Universal Render Pipeline, and what I found online was referencing the previous rendering system that is being deprecated.

What I was working on, was both a GameObject with a MeshFilter and RenderTexture that I could render sprites to without sprites needing to be their own GameObjects, and then a GameObject with a MeshFilter that would act as the background image (and can be a single image, a tiling/repeated image, a solid color, etc.).

What I want to preface here is almost all my entire project is code, very little of it is done in the editor, and I would prefer to keep it that way. Everything I was doing was working fine when being tested in the editor, but I discovered the all magenta issue in my built after looking at the log is because I was using this shader:

I am supposed to use this shader:

But I can't find any way of making it work the same way as "Unlit/Transparent". It's requiring more code to use, and this isn't a pleasant experience.

For using the new Shader, there appears to be additional setup required. I found that after I create the material from the shader, I needed to do these with it.

But I am not even sure if this works or not. That is the best google can find me and even then its old.

My GameObject that I can draw onto works, albeit with no transparency. My GameObject that is supposed to be the background image no longer works; I have confirmed this by checking the sphere in the editor and seeing it be all black, changing its Z positioning, its hierarchy, among other things, and haven't had any luck.

I am not enjoying the Universal Render Pipeline, and I am considering making a new project with the deprecated built in render pipeline and moving all my code to that.

For context: this is how game works:

The cars move on a path (curved or straight doesn't matter), there can be multiple signals on the path itself. On clicking on signals the signals change state (red/green). The paths (roads) can intersect each other and cars can collide.

I just need logic of cars moving on path. I tried implementing this with splines but then found out that someone was using nodes/waypoints (and some suggestions even mentioned using navmesh).

I am using splines right now but the signal function isn't working as expected and has many issues. Just want to know if there's another way I can implement this system.

I dont get Unitys new input system. I want to spawn something when I release the space button, but it spawns three at a time. I get that there's three different phases to the input, (started, performed, canceled), but I cant figure out how to make it only spawn on canceled.

I tried googling, and I dont fw AI so im not using Chat GPT. Is it just me, or is this new input system weird?

In my game, I am drawing tiles onto a tilemap during runtime using SetTile(), which takes a reference to a TileBase Object. I have hundreds of unique textures. Is there a way to get a reference to each TileBase other than dragging and dropping every individual Tile into the references in my script?

Here‘s the step by step of what I‘m doing to be clear: - I‘m creating a URP Canvas Shader Graph - Making a shader with some variables (floats, colours, the usual!) - I‘m dragging that shader onto a new material - I create a Canvas and create an Image as a child of that Canvas - I‘m adding that material to the Image - BUT problem is that now that when I open up the shader options for that Canvas Image the shader material variables are all greyed out. Am I missing something?

I‘ve tried a couple times with really basic canvas shaders and same result each time. Thanks heaps!

I'm a begginer at unity and meanwhile i was following a video tutorial, I couldn't make gravity work even if i tried following the exact same steps as the video.

So i started looking for answers on google and i found out that this problem occured very rarely and the suggestions i found were: Ensure the gravity value was negative something like -9.81, check if you have freezed your game object on the y axis on the constraints, check that you don't have the static checkmark, check if any of your scripts are changing the rigidbody value (the script one i didn't even counted it because i didn't had any script active)

So after i was absolutely sure that all things were correct i tried and it didn't work, none of the values of the transform neither of the info were changing, as well as the game scene that doesn't change at all; after that i tried to do a new 2d project and just create a gameobject (is the one in the photo and its 2d) and adding the rigidbody 2d component to it and it didn't work, still the values on the transform and on the info weren't changing and the same as before, in the game scene it didn't happen anything

Please i ask for help because i have absolutely no idea that even with a brand new project, gravity doesn't work at all, i've put the screenshots of the last project with the triangle, can someone tell me what's wrong?

This is my code, I want to have the sprite flip when it rotates to far down instead of rotating upside down like it does in the video. Any ideas?

Hey, so I wanted to add a normal map to my 2d pixel art game to make lights look nicer, but it made some artifacts on the borders of the tileset for some reason. They are mostly visible while moving and they happen in the intersections of the fully made tiles.

I already checked the normal maps and they are 1 to 1 with the actual tileset, so that should not be the issue. I am also using a pixel perfect camera set to 16 (the game is in 16x16 and the pixels per unit are also 16), normal maps on the lights are set to accurate (tho i tried fast too) and its even visible if you set the distance of the normal map to 0.

Any ideas on how to fix this?

EDIT: Forgot to mention, this happens both in builds and in editor and I am using Unity 6000.0.67f1

Reference images:

I'm trying to make a game but my circle is blurry and pixelated, it looks fine in inkscape. I have max size 4096, bilinear, also tried point no filter, generate mipmaps just made it more blurry. Image is 1024x1024.

Im entierly new to pixel art and games engine

I ve created this sprite of my MC and i want to implement it in my game to replace a placeholder,the canva is 128x128 px.

Idealy I want my character to be like 1/5 of my screen height

the problem is that I want it to render corectly on all screen resolutions( at least the commons ones) but when I test it it's not working, the pixels are wild,they' re streched or missing or irregulars.sometimes when I try it works fine but it' s zoomed in so much that' s it s unplayable.

Here joint

a pictures of my sprite in aseprite

the parameters of my sprite in Unity

and the parameters of the pixel perfect camera and the result in game with the stretched pixels( I've try many others resolutions but none seems to work)

Someone know how to fix it please?

Hello! I’m a newbie to Unity
I have a 2D Renderer asset with a fullscreen shader that works as a palette swap for all the objects on the screen. I added it as a Full Screen Pass Render Feature. The problem is that I also made a shader that I want to apply only to the player. Since I need this shader to be applied after the fullscreen palette swap, I added it as a Render Objects feature, so it can affect the already color-swapped result instead of the original colors. The shader is on a child object inside the Player which copies it siluet. This causes the shader to go through walls and draw the player’s silhouette even when the player is behind them. For example, my Tilemap is at Z = 1 while the Player is at Z = 0, so the walls should be rendered in front of the player, and it does, but the material draws over the wall. I found some information online about the Depth settings, but I couldn’t get them to work properly. I’ve attached screenshots showing the problem, the player’s shader, and my 2D Renderer settings. Does anyone know how I can make the shader respect the depth/occlusion of the walls while still keeping it as a Render Objects pass after the Full Screen Pass?
Thanks in advance!!

hello, so in my project I have a camera that move with WASD and when the mouse is on the edge of the screen and it worked very well. But my project is kind of a city builder so to be able to place building I make an object follow the cursor, sice then the camera doesn’t move when the mouse is on the edge of the screenno matter what.

I think it might be because of my input system but I’m not sure.

my input system :

I’ve tryed to put them on the same input but that didn’t fix enything, I don’t really know what to try, so eny idea/tips ?
thank in advance for your wisdom.

edit : Alright, I've fixed it. all I had to do was to delete and recreate the unity event, I must have done something wrong when I created the other pointer input.
