How can I simulate temperature in the BGE?

Heat vision 2d filter

Predator style heat vision for the BGE. [image] It’s not real heat vision, you have to add a lamp to illuminate the scene when you turn it on if the scene is dark, but it simulates the heat map style coloration of thermographic vision. You can combine it with other filters such as noise or blur to get a more interesting effect. I tried using depthTexture to get a true “seeing in the dark” type filter but the depth texture doesn’t pick up textures, transparent objects etc… so it wasn’t a good…

Note that the shader in the link above is a screen shader and not a OOP shader like you are looking for to work with game-properties.
