how to detect projectiles?

[imthevoidweresanitydies@g]

how would i go about detecting a projectile like the sandman ball from tf2? is it possible using brushes or map logic? keep in mind that i am ussing the tf2 verion of hammer, which is missing many features from future games.

I'm not sure if there is, but we could find a work around. What are you trying to do with it?



ETA: filter_activator_class could work, if you use the projectiles' classnames, ie tf_projectile_rocket
