Support / Solved: Creating full copies of first sprite sheet in same collection

« on: September 02, 2014, 06:12:33 pm »

Hello 2D Toolkit,

I want to create a copy from a sprite sheet including all sprite definitions.
I had this before in another game, but these were copied outside Unity, then I just changed the Spritesheet texture.

But now I want it in the same collection as the first one? How can I best do this? I am trying to make an Editor script. But I have no clue where to start.
I found a CopyFrom method in the script. But I don't know how to use it, because if I add an extra sprite sheet and copy this information, after that change the Texture. I am afraid it will not be saved or corrupt my Object somehow, because there will not be made sprite definitions for the new sheet I guess?

But I am afraid I break anything that has to do with 2D Toolkit, or maybe even my game. (though I made a back-up before I started this)
After this is done I want to create animations for it.

Some info:
- The sprite sheet consists of a front arm, back arm, legs and a male body, a female body and 4 heads.
- Some sprites have attachPoints while others have an different anchor.

So what I want is help with a script which copies the current sprite sheet, including definitions. Then change texture of the sprite sheet. (Maybe an idea for the Editor, a Copy button for sprite sheets)

I want all character sprites in one collection, because it will be called in the same Draw Call, at least that's what I've read. (So there will be better performance);

Currently what I have is this, put in a new scene on main camera, I just run the scene, then stop scene and I have new sprite sheet but not the data:

Code: [Select]

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

public class CloneSpriteCollections : MonoBehaviour {

	public tk2dSpriteCollection BaseCollection;
	public Texture2D[] textures;

	void Start() {
		List<tk2dSpriteSheetSource> spriteSheets = new List<tk2dSpriteSheetSource>();
		tk2dSpriteCollectionData data = BaseCollection.spriteCollection;
		tk2dSpriteSheetSource[] sources = BaseCollection.spriteSheets;	
		foreach (var v in spriteSheets)
		{
			var t = new tk2dSpriteSheetSource();
			t.CopyFrom(v);
			spriteSheets.Add(t);
		}
		// Adding the new spritesheets
		foreach(Texture2D texture in textures) {
			var t = new tk2dSpriteSheetSource();
			t.CopyFrom (sources [0]);
			t.texture = texture;
			spriteSheets.Add(t);
		}
		BaseCollection.spriteSheets = spriteSheets.ToArray ();


		List<tk2dSpriteDefinition> newDefs = new List<tk2dSpriteDefinition>();
		tk2dSpriteDefinition[] defs = data.spriteDefinitions;
		foreach (tk2dSpriteDefinition def in defs) {
			newDefs.Add (def);
		}
		int defOffset = 0;
		foreach (var v in spriteSheets) {
			int y = 288;
			for (int i = 0; i < y; i++) {
				tk2dSpriteDefinition def = defs[i];
				def.name = v.Name + "/" + i;
				newDefs.Add (def);
			}
		}
	}
}

While i reread my code I found out why, I don't convert the list back to the array! Let me try that first

So now I got this: Though it does not yet add the correct textures, it makes the definitions and stuff, it does not work correctly yet!

Code: [Select]

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

public class CloneSpriteCollections : MonoBehaviour {

	public tk2dSpriteCollection BaseCollection;
	public Texture2D[] textures;

	void Start() {
		List<tk2dSpriteSheetSource> spriteSheets = new List<tk2dSpriteSheetSource>();

		tk2dSpriteCollectionData data = BaseCollection.spriteCollection;
		tk2dSpriteSheetSource[] sources = BaseCollection.spriteSheets;	
		foreach (var v in sources)
		{
			var t = new tk2dSpriteSheetSource();
			t.CopyFrom(v);
			spriteSheets.Add(t);
		}
		// Adding the new spritesheets
		foreach(Texture2D texture in textures) {
			var t = new tk2dSpriteSheetSource();
			t.CopyFrom (sources [0]);
			t.texture = texture;
			spriteSheets.Add(t);
		}
		BaseCollection.spriteSheets = spriteSheets.ToArray ();

		tk2dSpriteCollectionDefinition[] cDefs = BaseCollection.textureParams;
		List<tk2dSpriteCollectionDefinition> newCDefs = new List<tk2dSpriteCollectionDefinition>();
		foreach (tk2dSpriteCollectionDefinition def in cDefs) {
			newCDefs.Add (def);
		}
		int sheetId = 1;
		foreach (var v in spriteSheets) {
			int y = 288;
			for (int i = 0; i < y; i++) {
				tk2dSpriteCollectionDefinition def = cDefs[i];
				def.spriteSheetId = sheetId;
				def.name = v.Name + "/" + i;
				newCDefs.Add (def);
			}
			sheetId++;
		}
		BaseCollection.textureParams = newCDefs.ToArray();

		List<tk2dSpriteDefinition> newDefs = new List<tk2dSpriteDefinition>();
		tk2dSpriteDefinition[] defs = data.spriteDefinitions;
		foreach (tk2dSpriteDefinition def in defs) {
			newDefs.Add (def);
		}
		
		foreach (var v in spriteSheets) {
			int y = 288;
			for (int i = 0; i < y; i++) {
				tk2dSpriteDefinition def = defs[i];
				def.name = v.Name + "/" + i;
				newDefs.Add (def);
			}
		}

		BaseCollection.spriteCollection.spriteDefinitions = newDefs.ToArray ();
	}
}
