I am trying to teach myself some pixel shader coding in order to spice up my games a bit while not having to rely on other people's work too much.
After a lot of headaches I managed to get something simple going by modifying the default "Flip Horizontal" code into a shader that scrolls whatever that is behind it.
Please login to see this picture.
In the above example the Cloud Backdrop is behind the Shader while the Active Object is on top of it it.
It would be mainly useful for games where you'd like the background to scroll without having to put in extra layers or move big images around. This way you're also not limited to scrolling entire objects but the targeted areas that the shader is covering.
The shader comes with an example file and the it's relatively easy to use as far as pixel shaders for Fusion games goes.
If there are any shader gurus out there, please let me know how I can improve in general. I don't even know what half of the code in the shader does.
