Check if something is colliding with a prop

[Ghost_Sailor]

I currently have

 for k, ply in pairs(player.GetAll()) do
	if (ply:GetPos():Distance(ent:LocalToWorld(ent:OBBCenter())) < rad) then
		inside = true
	end
end

But with long props, that ends up not working, and inside is true if a player is just near it.

Is there any way to accurately tell if anyone is inside/touching a prop?

Do a hull trace like this:
[lua]
local pos = ply:GetPos()
local tracedata = {}
tracedata.start = pos
tracedata.endpos = pos
tracedata.filter = ply
tracedata.mins = ply:OBBMins()
tracedata.maxs = ply:OBBMaxs()
local trace = util.TraceHull( tracedata )

if trace.Entity and !trace.Entity:IsWorld() and trace.Entity:IsValid() then
--They're touching something.
end
[/lua]

I used this to check if the player was stuck.
If you want to see if they're colliding rather than checking for being inside, add just a LITTLE more to the OBBMins() and OBBMaxs() of the player to check for objects just outside the bounds of the player.

I changed that to

		local inside = false
		local pos = ent:OBBCenter()
		local tracedata = {}
		tracedata.start = pos
		tracedata.endpos = pos
		tracedata.filter = {ply, game.GetWorld(), Entity(0)}
		tracedata.mins = ent:OBBMins()--*Vector(1.2,1.2,1.2)
		tracedata.maxs = ent:OBBMaxs()--*Vector(1.2,1.2,1.2)
		local trace = util.TraceHull( tracedata )
		ply:ChatPrint(tostring(trace.Entity))
		if trace.Entity and trace.Entity:IsPlayer() and trace.Entity:IsValid() and not trace.Entity:IsWorld() then
			inside = true
			ply:ChatPrint("You're inside!")
		end
	if inside == true then return false end

and trace.Entity is always the world, no matter what. Any ideas?

If it's a SENT you can use self:SetTrigger(true) and then use the built-in ENT:StartTouch and ENT:EndTouch

It's not an SENT. I'm calling it on the prop freeze hook.
