Fr. Gregori style traps?

02-25-2006, 02:44 PM
ok, im having quite a bit of trouble with this one, a friend of mine wants to make a Fr. Gregori style trap in one of my maps, but i have NO CLUE how to do it. i checked the sdk maps to see if i could figure it out but i cant.

what im trying to do is make a piano thats suspended by all 4 corners on the top it, leading to one joined rope. that rope will be going straight up to a pulley, over horizontaly to another pully, where the rope goes back down and connects to either a one time pull lever, or an object thats hevier than the piano and is breakable.

ive tried a few things but none have worked. anyone know how?

All I can say is that it is possible but it is VERY complicated, your talking alot of physics work there that will do little more than slow the map down.

but what your looking for are phys_constraint, Phys_hinge, prop_physics_multiplayer.

tie the piano to a trigger motion enable/disable trigger on the destruction of the hinge.

Cant tell you more because ive never done it but I believe those are the basics.

Maybe you could somehow decompile the HL2 level Ravenholm? They have that in the map... except it's a car attached to a pulley system and a lever... but if you see it there, shouldn't be too hard to figure it out.

do the same tools work for decompiling source maps as 1.3 maps? or is there a diff tool i need to get?

Vmex is what ive used to look at stock source maps

Yeah VMEX is the thing to use, but first you have to use GCFScape to extract the official maps

thanks, worked like a charm, but you cant get the props to actually hurt people :-(

I suspected as much, what you probably need is to surround the prop with a nodraw box and tie that to func_physbox.

In the settings you can motion disable it etc and change its mass, this should make it kill people.

In one of my CS maps there was a control tower that was made up of these so when the bomb went off the whole thing blew apart and ppl were gettin killed by the debris ;)
