Deleting the color channel

[zeteginara]

I made a color channel on my tilemap to make it look like nighttime.  I have designed it so, when the scene loads, on start it checks to see if a flag exists, and if so, I want to programatically delete the color channel.  Here's my code:

var channel = GameObject.Find("TileMap").GetComponent<tk2dTileMap>().ColorChannel;
channel.Delete();
GameObject.Find("TileMap").GetComponent<tk2dTileMap>().Build();

I've also tried:

var channel = GameObject.Find("TileMap").GetComponent<tk2dTileMap>().ColorChannel;
channel.Clear(Color.white);
GameObject.Find("TileMap").GetComponent<tk2dTileMap>().Build();

Neither of them get rid of the color channel, it stays 'nighttime'.  What am I doing wrong?

Have you tried calling
GameObject.Find("TileMap").GetComponent<tk2dTileMap>().DeleteColorChannel();
followed by
GameObject.Find("TileMap").GetComponent<tk2dTileMap>().ForceBuild();

This isn't a great way to do it as its really quite slow. A better option would be to change the shader on your material to one that doesn't use vertex colors. That will be instant.

I'm currently using the  tk2d/CutoutVertexCoor shader because of this:

Does that suffice?  If so, how do I make it instant?

Also, is there any way to lerp the color?  I want the color channel to be able to transition to clear, to represent sunrise, etc.

Are you fililng the whole color thing with one color? If so just use one of the unity built in shaders that have a color parameter, you can simply change that to tint the whole screen, transitions will be close to free.


You will need to find a cutout shader that has a color parameter if you need to use cutout, or create one yourself.
