How many people are trying to figure out how to...

You know, the one when you can drop the car on the zombies?

This would be a great trap, not just with cars, but with loads of other
objects as well. I'm not looking for anyone to tell me how to do
it, I just want to see how many of you are working on it or have a
working trap already.

Also, post here if you'd like to see a video tutorial on it. Just as a heads up - I've almost got it figured out...

I can't imagine it's hard (or that there's one way to do it), there should be a convoluted way to do it with lengthconstraints and invisible trains! Feel free to do a written tutorial too and posting it here :wink:

It's actually quite complicated. Definately not a Novice, or even an Intermediate, tutorial.

I'm thinking that I'll do a write up tutorial first, but still link to
the video tut, cause I know I learn easiest by watching what exactly is
going on...

Whats the problem? A object tied up onto a rope attached to a func_train that operates via a lever?

LOL

Try that, it wont work... The rope will show up, but you wont be
able to move the car (with the gravity gun, like you can in HL2) Plus,
the func_train doesn't provide the "smooth ride" up like in HL2.

If you want a trap that will fall on people, I can make that easily, it's the physics part that's not easy...

I'd think a phys_spring (with a reasonably stiff spring constant)
should work. See the sdk_phys_spring map for how to alter the spring
length. The rest would be just visual effects of the lever, engine and
rope.

That's a nice try Rof. I hadn't thought of that, so I went in and
played with it for the last half hour. There is potential there,
by controlling the length of the spring to pull it up, then lengthening
it to drop it down, but it pulls it up to fast, and drops it down to
slow... Should be the other way around...

I found a way to drop it down quickly, the difficult part is making it
go back up. Trains don't work, I'm thinking it's
phys_lengthconstraint, but it's not working properly...
