Make Particles block Raycasts/Linecasts

[sevensixtytwo]

I want to make my AI be unable to “see” targets behind a smoke screen Particle System. I generally use Linecasts and Raycasts to check AI awareness, but they ignore particles even with World Colliders checked. I can’t use Triggers because I use trigger colliders for something else (flocking and obstacle avoidance).

Is there any way to stop Raycasts when they hit a particle? If not, what would be a good way to implement vision-blocking smoke screens for AI?

You can use triggers! Just put the different sets of colliders on different layers, and set up collision detection and masks on your raycasts to make it all work.
