So I know (through searching) that you can easily simulate a flash by using a white sprite over everything but with the WebGL and the example given by Construct 2 : WebGL Shader luminance transition, I want to be able to recreate this effect in my project but just simply copying the events over isn't working.
I also can't seem to find what has been done outside of the events page.
P.S. Hello world! (1st post ever)
