flip & rotate

[rakkarage]

i guess all possibilitie combinations can be covered with 3 bools

        uv[index + 0] = ToUv(new Vector2(tr.xMin, tr.yMin), Texture);
        uv[index + 1] = ToUv(new Vector2(tr.xMax, tr.yMin), Texture);
        uv[index + 2] = ToUv(new Vector2(tr.xMin, tr.yMax), Texture);
        uv[index + 3] = ToUv(new Vector2(tr.xMax, tr.yMax), Texture);
        if (rotate)
        {
            var temp0 = uv[index + 0];
            var temp1 = uv[index + 1];
            var temp2 = uv[index + 2];
            var temp3 = uv[index + 3];
            uv[index + 0] = temp2;
            uv[index + 1] = temp0;
            uv[index + 2] = temp3;
            uv[index + 3] = temp1;
        }
        if (flipH)
        {
            var temp0 = uv[index + 0];
            var temp1 = uv[index + 1];
            var temp2 = uv[index + 2];
            var temp3 = uv[index + 3];
            uv[index + 0] = temp1;
            uv[index + 1] = temp0;
            uv[index + 2] = temp3;
            uv[index + 3] = temp2;
        }
        if (flipV)
        {
            var temp0 = uv[index + 0];
            var temp1 = uv[index + 1];
            var temp2 = uv[index + 2];
            var temp3 = uv[index + 3];
            uv[index + 0] = temp2;
            uv[index + 1] = temp3;
            uv[index + 2] = temp0;
            uv[index + 3] = temp1;
        }

a little simpler at least but prob not optimal

Sorry I missed this. Seems like I'm not getting notification emails.

Is this something you wont to add to TileMeshQuadGridBehaviour.cs? If so, could you create a pull request for it?

[rakkarage]

sorry mine has diverged too far from this one

1. cannot use the editor with 4096 tiles (102x1024 sheet & 16x16 tiles) because too slow
2. everything but quad grid seems useless to me why setPixel when you can not
3. passing a sprite in is not really needed... just the texture the rect can be calculated from the id
   i did try to make this work with the example in your code but gave up after a while trying to remove sprite parameter and thread all rotatation and flip parameters throgh inheritance

for example to get stairs flipping in showcase

but here is my code for that function if anyone else would like to try or use

    public int TextureIndex(Vector2 p)
    {
        return TextureIndex((int)p.x, (int)p.y);
    }
    public int TextureIndex(int x, int y)
    {
        float s = Texture.width / TileSize;
        return (y * (int)s) + x;
    }
    public Vector2 TexturePosition(int index)
    {
        int s = Texture.width / TileSize;
        int y = index / s;
        int x = index - (s * y);
        return new Vector2(x, y);
    }

    public void SetTileFlags(int x, int y, bool flipH, bool flipV, bool rotate)
    {
        SetTile(x, y, GetTile(x, y), flipH, flipV, rotate);
    }
    public void SetTile(int x, int y, int id, bool flipH = false, bool flipV = false, bool rotate = false)
    {
        SetTile(TileIndex(x, y), id, flipH, flipV, rotate);
    }
    public void SetTile(int index, int id, bool flipH = false, bool flipV = false, bool rotate = false)
    {
        if (id == -1) id = 4096;
        _data[index] = id;
        var tp = TexturePosition(id);
        tp = new Vector2(tp.x * TileSize, tp.y * TileSize);
        tp.y = Texture.height - tp.y - TileSize;
        var tr = new Rect(tp.x, tp.y, TileSize, TileSize);
        var uv = _meshFilter.sharedMesh.uv;
        index *= 4;
        uv[index + 0] = ToUv(new Vector2(tr.xMin, tr.yMin), Texture);
        uv[index + 1] = ToUv(new Vector2(tr.xMax, tr.yMin), Texture);
        uv[index + 2] = ToUv(new Vector2(tr.xMin, tr.yMax), Texture);
        uv[index + 3] = ToUv(new Vector2(tr.xMax, tr.yMax), Texture);
        if (rotate)
        {
            var temp0 = uv[index + 0];
            var temp1 = uv[index + 1];
            var temp2 = uv[index + 2];
            var temp3 = uv[index + 3];
            uv[index + 0] = temp2;
            uv[index + 1] = temp0;
            uv[index + 2] = temp3;
            uv[index + 3] = temp1;
        }
        if (flipH)
        {
            var temp0 = uv[index + 0];
            var temp1 = uv[index + 1];
            var temp2 = uv[index + 2];
            var temp3 = uv[index + 3];
            uv[index + 0] = temp1;
            uv[index + 1] = temp0;
            uv[index + 2] = temp3;
            uv[index + 3] = temp2;
        }
        if (flipV)
        {
            var temp0 = uv[index + 0];
            var temp1 = uv[index + 1];
            var temp2 = uv[index + 2];
            var temp3 = uv[index + 3];
            uv[index + 0] = temp2;
            uv[index + 1] = temp3;
            uv[index + 2] = temp0;
            uv[index + 3] = temp1;
        }
        _meshFilter.sharedMesh.uv = uv;
    }

and here is a simple tile animation system i got working in mine to complete the transition from 2dtoolkit

for example if you had a water or wall torch tile with a couple frames of animation

    public void SetAnimation(int index, int[] frames, float fps)
    {
        StartCoroutine(Animation(index, new int[][] { frames }, fps));
    }
    public void SetAnimation(int index, int[][] frames, float fps)
    {
        StartCoroutine(Animation(index, frames, fps));
    }
    private IEnumerator Animation(int index, int[][] frames, float fps)
    {
        var time = 1f / fps;
        var animationIndex = 0;
        var frameIndex = 0;
        while (true)
        {
            if (animationIndex >= frames.Length) animationIndex = 0;
            if (frameIndex >= frames[animationIndex].Length)
            {
                animationIndex = Utility.Random(frames.Length);
                frameIndex = 0;
            }
            SetTile(index, frames[animationIndex][frameIndex]);
            frameIndex++;
            yield return new WaitForSeconds(time);
        }
    }

i guess i could add the functions to quad grid but i cannot see how to make Showcase use it

thanks

The editor inside Unity will probably be removed and replaced with Tiled coupled with some kind if importing script. Closing this for now, if someone wants to pick up and continue the work feel free to reopen.
