Android shader on touch

Post by xNick1 »

Hi guys.
I couldn't really find an "easy" way to make a shader I need in opengl es.
It has to work on Android and iOS.
I need something like a "bubble" to appear in the touched spot.
Something like "hey, you tapped right here".

I don't really know where to start.
I used shine in the past but it doesn't work on mobile.

It doesn't really sound like you need a shader at all. Just use love.touchpressed etc to draw a bubble?

If you want to do some displacement, then you can render your scene to a canvas and then draw the canvas with the shader attached. You will need externs (uniforms) to send information to the shader, it would make sense to send for example the x and y position and the radius as it increases over time using Shader:send.

Code: Select all

print( type(love) )
if false then
  baby:hurt(me)
end
