Hello,

  1. I have a texture with multiple 64 x 64 tiles.

  2. I have a few quads in the scene, and I would like the quads to use some of the tiles from the texture.

  3. I would like to drag and drop a script on the quad and edit the public variables so I can pick the right files.

x_offset = 0
y_offset = 0
tile_size = 64
tile_sheet = 384

the material is using a 384x384 texture
this is my code but it doesn’t seem to be working. I cant figure out whats wrong.

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

public class TileChooser : MonoBehaviour {
	public int tile_x;
	public int tile_y;
	public int tile_size;
	public int sheet_size;
	private Renderer rend;

	// Use this for initialization
	void Start () {
		rend = GetComponent<Renderer>();

		rend.material.mainTextureScale = (new Vector2(tile_size/sheet_size,tile_size/sheet_size));
		rend.material.SetTextureOffset("_MainTex", new Vector2(tile_x,tile_y)); 
	
	}
	
	// Update is called once per frame
	void Update () {
		
	}
}

Hello, I have finally figured out how to set a Quads Texture to a tile from a tileset.
I’ve noticed there are 92 followers so I decided to update the answer.

  1. create a material that has the tileset.

  2. add a script to your project, use the code I have provded.

  3. drag and drop the script on to the quad in your scene.

  4. edit the public variables.

    • sheet_size, is the size of your tile sheet eg: 256x256
    • tile_size is the size of your tiles, eg 32x32, 64x64, 16x16, ect.
    • tile_x is which tile you want, 0,1,2,3,4, starting from left
    • tile_y is the tile you want STARTING FROM THE BOTTOM OF THE SHEET, eg 0,1,2,3,4
    • it may help to change the IMPORT SETTINGS on your TEXTURE. set “WRAP MODE” to CLAMP.

  5. enjoy

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

    public class TileChooser : MonoBehaviour {
    public float tile_x;
    public float tile_y;
    public float tile_size;
    public float sheet_size;
    private Renderer rend;

    // Use this for initialization
void Start () {
	rend = GetComponent<Renderer>();
	rend.material.mainTextureScale = (new Vector2(tile_size/sheet_size,tile_size/sheet_size));
	rend.material.SetTextureOffset("_MainTex", new Vector2(tile_x*(tile_size/sheet_size),tile_y*(tile_size/sheet_size))); 

}

// Update is called once per frame
void Update () {
}

    }
