How to best render a sprite in an EditorWindow and add a Click Event to it?

Hi,

I am currently working on a little Tile-based Map Editor, using unity sprites.
The problem right now is, that I don’t know the best way to render a single sprite (not the whole sheet) inside an editor window.

What I currently do is, that I take the sprites texture, and render a part of it into a new Texture2D, using the GetPixels function and the sprites textureRect. However, to do this inside a Script, the texture needs to have some specific import settings for me to be allowed to read data from it. (Where do I set the import properties?)

Also I would like to know how I add a click event to this sprite.

Hi !

You can render a Sprite into EditorGUI using…

GUI.DrawTextureWithTexCoords or Graphics.DrawTexture

Here’s some code from one of my project.
I’m using thoses functions to display my sprites on my own EditorWindow

	public static void DrawTexture(Rect position, Sprite sprite, Vector2 size)
	{
		Rect spriteRect = new Rect(sprite.rect.x / sprite.texture.width, sprite.rect.y / sprite.texture.height,
								   sprite.rect.width / sprite.texture.width, sprite.rect.height / sprite.texture.height);
		Vector2 actualSize = size;

		actualSize.y *= (sprite.rect.height / sprite.rect.width);
		Graphics.DrawTexture(new Rect(position.x, position.y + (size.y - actualSize.y) / 2, actualSize.x, actualSize.y), sprite.texture, spriteRect, 0, 0, 0, 0);
	}


	public static void DrawTextureGUI(Rect position, Sprite sprite, Vector2 size)
	{
		Rect spriteRect = new Rect(sprite.rect.x / sprite.texture.width, sprite.rect.y / sprite.texture.height,
								   sprite.rect.width / sprite.texture.width, sprite.rect.height / sprite.texture.height);
		Vector2 actualSize = size;

		actualSize.y *= (sprite.rect.height / sprite.rect.width);
		GUI.DrawTextureWithTexCoords(new Rect(position.x, position.y + (size.y - actualSize.y) / 2, actualSize.x, actualSize.y), sprite.texture, spriteRect);
	}

Hope it’s help !

I don’t quite understand the problem, but setting the sprite sheet’s mode to multiple and then in the Sprite Editor, you slice them using the automatic slicer on the top left. Does this help?
