A planet made entirely out of text symbols. The entire screen image is drawn symbol by symbol. Each symbol's position is calculated in real time. There’s only one texture with symbols and a lot of sprites on the screen. Created a text editor on a sphere to make planets for my game Effulgence.

Efficient way to cycle through sprites in a texture?

I have have a texture with multiple sprites like this:

https://preview.redd.it/0kdpez14sazd1.png?width=245&format=png&auto=webp&s=198405b4bc607a8d66f68d633c86c028675a741b

What I want to do is basically at certain points switch between different sprites in the texture (in the case, it is a crop that is growing with different stages). What I have come up with so far is this:

using ProjectEdg.CoreModule;
using UnityEngine;

namespace ProjectEdg.TextureModule {
public class MultiTextureComponent : MonoBehaviour {
[SerializeField]
private SpriteRenderer _spriteRenderer;

[FoldoutGroup("Debug")]
[SerializeField]
[ReadOnly]
private Texture2D _texture;

[FoldoutGroup("Debug")]
[SerializeField]
[ReadOnly]
private MultiTextureData _multiTextureData;

private float _updateArea = 1f;

private int stage;

private string[] _spriteNames = new string[] { "ParsnipPlant1", "ParsnipPlant2", "ParsnipPlant3" };

#region lifecycle

private void Start() {
_multiTextureData = ResourceManager.Instance.GetTextureData("FarmingCrops");
_texture = ResourceManager.Instance.GetTexture("FarmingCrops");

SetCroppedArea(_spriteNames[stage % 3]);
}

private void Update() {
if (_updateArea > 0) {
_updateArea -= Time.deltaTime;

return;
}

stage += 1;
SetCroppedArea(_spriteNames[stage % 3]);
_updateArea = 1f;
}

#endregion

private void SetCroppedArea(string spriteName) {
var spriteData = ResourceManager.Instance.GetTextureSpriteData("FarmingCrops", spriteName);

if (spriteData == null) {
return;
}

var startingPosition = new Vector2Int(spriteData.StartX, spriteData.StartY);
var size = new Vector2Int(spriteData.Width, spriteData.Height);
var centerOffset = new Vector2(
spriteData.CenterOffsetX != -1 ? spriteData.CenterOffsetX : _multiTextureData.DefaultCenterOffsetX,
spriteData.CenterOffsetY != -1 ? spriteData.CenterOffsetY : _multiTextureData.DefaultCenterOffsetY
);

if (startingPosition.x + size.x > _texture.width || startingPosition.y + size.y > _texture.height) {
LogManager.LogError("the attempted crop area is out of bounds of the texture");

return;
}

var croppedPixels = _texture.GetPixels(startingPosition.x, startingPosition.y, size.x, size.y);
var croppedTexture = new Texture2D(size.x, size.y);

croppedTexture.SetPixels(croppedPixels);
croppedTexture.filterMode = FilterMode.Point;
croppedTexture.Apply();

_spriteRenderer.sprite = Sprite.Create(
croppedTexture,
new Rect(0, 0, size.x, size.y),
new Vector2(centerOffset.x / spriteData.Width, centerOffset.y / spriteData.Height),
_multiTextureData.PixelsPerUnit
);
}
}
}

While this works, my concern with this approach is that each time I am changing the sprite to render, I am creating a new `Texture2D` and `Sprite` and was wondering if there is a more efficient way to do this. For example in Godot, I can have a sprite use the main texture and then just set the region rect for the sprite without creating this extra data (at least explicitly, I don't know what is happening under the hood) and was wondering if there is something like that in Unity?

The best approach I can think of is when loading the main texture, I create and cache the individual textures / sprites in the texture and then just reference those cached items when I need to (like my current example is doing for the main texture). This has the downside that I have to store

all the textures / sprites in memory even when I am not using them.

Is this a good approach? Is there something else already built-in that would handle part of this for me?

How do you deal with Light 2D and objects?

What option do you prefer:

a) I can illuminate trees and objects when the lantern is facing them: https://imgur.com/gallery/spreading-light-V1cYVi2

b) Or I can leave them dark: https://imgur.com/a/e12xoEe

or a different option. Which one do you prefer? can you think of a different solution?

Why won't pressing a button on my controller trigger the function?

I've started making a new game recently and I've been trying to add controller support as I implement more things. I've created a function that is supposed to show and hide the inventory by pressing either E on a keyboard or the "North Button" on a controller (Triangle on playstation, X on switch and Y on xbox). Pressing E works fine, but pressing Triangle on my PS5 controller does nothing. Unity isn't telling me there's an error, it still detects when I press the button elsewhere in Unity, and moving with the Left Stick still works perfectly fine.
Can anyone figure out what I'm doing wrong?

{
controls = new @PlayerGmaepadControler();

controls.Gameplay.ToggleInventory.performed += ctx => ToggleInventory();
}

[SerializeField] GameObject _object;
// Start is called before the first frame update
void Start()
{

}

// Update is called once per frame
void Update()
{
if (Input.GetKeyDown(KeyCode.E))
{
ToggleInventory();
}
}

void ToggleInventory()
{
bool currentState = _object.activeSelf;
_object.SetActive(!currentState);
}
}

How to use hold Touch as Input to execute action in Update function? For mobile.

Hey guys, I was inspired by Dani Dev to start gamedev and I've spent quite a few months just creating my first game for mobile similar to his farty Rocket that he created in 1 hour lol. the problem is I can't find any way to move my player when the user taps and holds the screen. I've done everything else perfectly fine but I just don't understand any tutorial on this type of mobile input for this silly little 2d game. this is my code:

void Update()

{

if (gameManager.IsState(GameState.Playing))

{

//Need to put Mobile inputs here but whichever one i try it with it doesn't accomplish anything.***

if (Input.GetKey(KeyCode.Space) || Input.GetKey(KeyCode.UpArrow))

rb2d.AddForce(Vector2.up * flyForce * Time.deltaTime * 1000f);



// Rotates ship

float angle = Mathf.Atan(rb2d.velocity.y / rotation) * Mathf.Rad2Deg;

transform.rotation = Quaternion.Euler(new Vector3(0, 0, angle));

}

} this is the video that can explain what kind of input I am talking about.. at 4:41 https://youtu.be/LrFm8hq3gsA?si=BWcEf8hJJkPkdjQh

I have a hexagon tile map grid. I want to implement a feature where honey combs can be dragged and placed at predetermined positions. Is that possible with the tile map or do I have to make my own grid system?
