How to Whiten a Sprite Gradually

[ExCx]

Hi, I need to make a sprite go completely white. I mean like a white silhouette of itself. I can change the shader to do it instantly, but how can I do it gradually?

This is somehow what i want to know as well.

I think you would need to make a custom shader.

You could copy and change an existing tk2d shader so that the vertex colour is added instead of multiplied. Your sprite colours would then need to be black instead of white by default to be in their 'normal' state. Then when you lerp the tk2d sprite colour to white, the sprite pixels should move towards a solid white instead of being tinted. That's my theory anyway.

You could try this shader:
