[SOLVED] How to do this visual effect?

[spectralcanine]

You are running three texture fetches for the same coordinate, that's not very ideal.

Code: Select all

texture2D(tex0,uv).xyz // or .rgb, whatever you fancy

Hey there, could you please tell me how to move where the center of the ripple appears? Been trying to figure it out for a while but Shaders sure are difficult .

I've been playing around with it and can't quite seem to figure this out too. retrotails we need halp pls!
And is it possible to do multiple waves at the same time?

Also, where did you start out when learning how to use shaders?

Look at what's changed, it's pretty simple. As for multiple waves, that requires multiple passes, and my implementation of that seems rather glitchy. Perhaps someone with more shader/love experience can help on that.
As for using shaders, I started a few months ago with absolutely zero C knowledge (a prerequisite, so they say) having only coded in Lua and Visual Basic. I just took some examples and modified them. Then I went crazy making all the shaders I could for this game

I stopped working on it because of a lack of community interest and also I never kept track of it's really complicated render pipeline.
