How can I check if a trace is a prop

Same as the title ?

How can I check if a trace is a physics prop ?

I’m not really sure what you mean. If you want to check if a trace hits a physics prop, do this:
[lua]if ValidEntity(trace.Entity) and string.find(trace.Entity:GetClass(), “prop_physics”) then
– Code here.
end[/lua]

Thanks that’s what I needed

I would like to know why I got a dumb, could someone please enlighten me?

Probably because the majority of FP users like to troll people by rating them.

I would like to know why FlapJack got a dumb.

And why I got a dumb.

Because of your dumb avatar.

You don’t like me?
