Some progress: env_shooter using point simulated gibs can be detected as debris by a trigger, so that acts as a relatively efficient traceline test for where the laser hits a portal. Incident angles are inaccurate, but a logic_lineto seems to work for that (passing on a vector for the exit laser).
My problem now is that env_shooter doesn't work properly when parented to a physbox. Transformations of the box seem to be added to those of the shooter, so it won't fire in a straight line. Also you can't detect the shooter's gibs with a trigger_teleport to send them to a target parented to the box. So any alternative ideas for how I might test where the func_tanklaser hits a portal? > From: mbortol...@hotmail.com > To: hlmappers@list.valvesoftware.com > Date: Mon, 5 Jul 2010 22:42:53 +0000 > Subject: [hlmappers] [Portal] Hacky ent setup for lasers through portals > > > I've been trying to rig a movable func_tanklaser (parented to physbox) that > appears to shoot through portals.
