Painting on walls InGame ?

Hi:)

As the title suggests, my team and I are trying to find a way to allow the player to paint on walls ingame.
We are working on a 2,5D JumpNRun prototype. So the player would be using the mouse cursor to paint on on the walls behind the player character.

Here is what i have been thinking about. But then again, I am a beginner x)

  • I could imagine doing it with particles, but I wouldnt be surprised if that was resource intensive, especially since I dont want the particles to disappear after a while.
  • Maybe somehow revealing an underlying texture via an alpha channel could be a possibility… But then then the player would be restricted to just one color (?)

I would love to hear how you guys would approach this… =)…
