Help Fluid Particles interaction Script

[JoseCarlos S]

Hi, im developing a game, and i would like to implement an interaction between to fluids (fluid A and fluid B, the particles destroy each other when in contact). I saw a thread that said fluid particles cant detect collision directly, they have to detect it by vorticity or temperature... How do you set it up so that each particle has differnt temperature? And how would a script that destroys them "onCollision" look like?

Thank you.
