Animated Texture or Shader in Flashing Platform?


I want to achive flashing platform like in Blasto game : Flashing Platforms Blasto - YouTube

I wonder what technique should i use to do something like this. If anyone can point me i will be glad

Check out this page on the wiki that animates a texture:

What you’d want is something like 3 frames of ‘dark’ and one frame of ‘flash’ (feel free to play with different numbers to get the feel you want).
