I've found env_entity_igniter but I can't figure out how to set a player on fire with it.

have you try using a trigger_func

or trigger_hurt

no, I haven't. But the devs told me that I gotta use info_fire_system but I haven't figured out how to use it

did you set the info_fire_system to Active

and also did you get the info_fire_system a name plus the zombie as well (OutPuts)

add a zombie to your map give the zombie a name (what ever you want to call it)

add a info_fire_system (also give it a name)

place down a trigger-box also give the trigger-box a name

then go over to you"re trigger box then go to outputs

.on start touch
.fire kill zombie then name what you gave it
.start

then your zombie should be on fire when you touch the trigger box i hope this help you out also im a bit of a noob on sdk

hey smike, thanks! but by zombie I meant a player zombie. How do I set myself on fire when playing as a zombie?

im not quite sure yet lol
