Trebuchet?

[FictiousWill]

Has anyone made a successful trebuchet?

I made one that works well, only it doesn't release correctly at the top of the swing. I loaded it with a car and managed to throw it a mile high, but that wasn't the idea.

I'll keep tweaking mine, in the meantime has anyone actually gotten one to function correctly?

(I don't mean getting the entities to interact right, I have that, but making a trebuchet sling release right is more of an art)

never knew anyone made one or is working on it

I thought I heard about a tutorial for one over at HL2World... but I haven't checked it out yet.

what's a trebuchet?

It's a gravity (as opposed to tension or compression) powered catapult invented by the French.

Dont really know, but the idea sounds amazing :O Damnit Source rules.
Could be a nice map, like 2 forts and both teams have catapults and you have to crush the opponent´s fort

That one from the stam forums is fantastic - I was using a modeled sling at the end of mine, but he just uses a breakable cable, much better idea.

Plus that destructible building is very awesome.

I thought about attempting it, but it seemed way beyond my capabilities. Besides, can you spawn the same entity with the same name to the same rope after the other one was launched? :O

The map from the forum is nice. I thought it interesting that if you ride in the buggy when it shoots it lands past the building and doesn't destroy. So your "weight" made it go further... which I don't think is right, physics-wise.

You can even drive the buggy with the cable atached and it still works, although it changes where it falls. You can also leap from the buggy mid-air, although when I was high up I instantly died. Not sure if that was just the buggy falling on top of me or what.

Nicely done.

Actually, there is a good chance your "weight" would make it go farther. While it make take more energy to throw, it also will take more energy to slow down. You need just the perfect weight for prime heigth (sp?).

That has to be the best/funnest user made map I have ever played. And for those of you who didnt read through all 8 pages, he made a 3rd version, where you can re-attach it to the catapault with magnets:

http://myweb.cebridge.net/michaell/trebuchetcanyon3.zip

here is a resettable version.

you have to drive the buggy back into position after each throw and reattach the magnetic hook using the gravity gun.

Instructions:

1. The first ting you need to do is set up the Treb's arm. this is done by pressing the button closest to you when the map starts.

It works by giving the hinge an angular velocity which slowly lowers the arm into firing position. a phys_magnet (the upsidedown bottle is a placeholder for it) then attaches onto the metal treb arm and resets the angular velocity to 0, the magnet at this point is holding down the arm. as it attaches, it turns on the phys_magnet (the hook) on the sling.

2.After the arm is down, drive the buggy into position and use the gravity gun to stick the hook onto the buggy. remember its a magnet, you don't have to hook it around the frame or anything.

3. finally, press or shoot the other button to fire the treb.

This button will release the magnet holding down the treb arm and finally release the magnet holding onto the buggy after a set time.

I am aware there are several ways to muck things up, (sticking the hook to the treb arm, or maybe driving the buggy onto the ground magnet) I think all of these problems can be fixed by cycling the system, press the fire button and then the reset button again to try again.

Also, you may get the hook sticking to the treb arm or the ground magnet on its own, don't worry, just fire the treb and reset it again to try again. it is very much unpredictable. and thats why I made the ground magnet model so small so theres less of a chance of the hook randomly attaching itself to it.
