Stopping projectiles via LUA?

[Bridget]

Is there any way to stop rockets from passing a trigger-textured area via LUA?
Players must be able to pass, but not rockets.

I think trigger_ff_clip will do this. It doesn't do everything it's supposed to do, but it does block projectiles.

You can use a trigger_remove (check "Everything" and then use the code below to only remove projectiles) or a trigger_ff_clip.

Trigger_remove (named projectile_remove)

remove_projectiles = trigger_ff_script:new({ })

function remove_projectiles:allowed(allowed_entity)
	if IsNotProjectile(allowed_entity) then
		return false
	end
	return true
end

function IsNotProjectile( allowed_entity )
	return IsPlayer(allowed_entity) || IsGrenade(allowed_entity) || IsTurret(allowed_entity) || IsDispenser(allowed_entity) || IsSentrygun(allowed_entity) || IsDetpack(allowed_entity)
end

Trigger_ff_clip (named projectile_clip)

projectile_clip = trigger_ff_clip:new({ clipflags = {ClipFlags.kClipProjectiles} })

Not sure if trigger_ff_clip works 100% correctly. Trigger_remove will remove the projectile completely, and trigger_ff_clip will act as a wall.

Thanks, and instead of making a new thread.. I have another question.

Currently, I have two brushes set to trigger_teleport. One to teleport to red side, one to teleport to blue side. They both work, but not as I want. So, how would I go about (through lua) only allowing (if possible) the teleporter to work if the person who enters the teleporter shares the same team as the teleporter?

[squeek.]

team_only = trigger_ff_script:new({ team = Team.kUnassigned })

function team_only:allowed( allowed_entity )
	if IsPlayer( allowed_entity ) then
		local player = CastToPlayer( allowed_entity )
		-- return true if the player is on the right team
		return player:GetTeamId() == self.team 
	end
	return EVENT_DISALLOWED
end

blue_only = team_only:new({ team = Team.kBlue })
red_only = team_only:new({ team = Team.kRed })

Name the trigger_teleports red_only and blue_only
