rope parent:barrel Created 19 years ago2005-02-09 17:05:04 UTC by Madcow

I made a rope and stuck it to a barrel (using parent) and the other edge in a brush (not using parent)
But the rope goes nutz!!
I made slack: 0, so tehre would be no extra rope. but the rope expands and gues through walls when I play the map.
What's wrong with the rope?
How do I make the size of the rope "stuck" (same value all the time)
((My english still sucks..))

Well,, can you guys help me?

thanks!

You need to actuely create a rope the keyframe crap is the phsyical side that makes it look like a rope what you need is a phys_lengthconstraint.

do you want the barrel to move?

If yes, your gonna need a move_rope. parent the move_rope to the barrel. Then make the keyframe_rope to whereever you want the rope to be. Work out the values and flags then test.

I hope thats what you needed. I remmebered that from Snark Pit.

Er, if you want to hang the barrel and have the rope have a set length, you need to setup a phys_lengthconstraint affecting the barrel.

How do I do that thing with the phys_lengthconstraint?
I tested it.. but I didn't understand anything.. ( lol ) :

you place the phys_lengthconstraints right on top of the keyframe_ropes. I think thats how i did it. I cant get to the snarkpit, they had a tutor on it that i used and it worked, pretty simple too. Anyone know why that site is down? Id check it out on my example map that I made but my computer is still compiling lol.

keyframe_rope? oops.. used move_rope.. =/
What's the difference?

Well, I tested it again,, I'll post it as a problem map cuz I just dont get it.
The ropes length expands when I start the map..

But thanks for your help anyway!

Il create an examble map

@LT: Snarkpit is down since Oktagone removed their entire US hosting setup. It's returning, sometime.

As for teh constraints, there's a SDK map as well.

Is there a SDK map? (DOH!!)
What's the name of that map?

blackravent: I tested your map! And I tried to make something like it in my own map.. But the rope acts like a rubberband.. O.o
How do I remove that?

Ok i looked at the example map i made with the tire swing which I think is basicly the same thing your doing but with a barrel instead. You use a move_rope entity and place that where your rope starts ( what it will be attched to, like a branch of a tree for example on a tire swing) then you make a keyframe_rope and name it something like keyframe_rope1, and place it where it conects to the barrel. Now name the barrel to something like swinging_barrel or whatever and amke sure the barrel is a prop_physics. Go into the keyframe_rope entity and in the parent field put the name of the barrel, in this case "swinging_barrel". Now go into your move_rope entity and put in it the next keyframe field the name of the keyframe_rope entity, in this case "keyframe_rope1". Now make a phys_lengthconstraint and put it in the exact same place as the keyframe_rope entity and name it something like "lengthconstraint_1". Now go to the "entity 1" field and type in or select the name of the barrel, which in this lil guide would be called "swinging_barrel". Thats it, tell me how it goes!

Oh crap, one more thing. Click on the phys_lengthconstraint and you will see a little circle thing in the middle. drag that lil bastard up to your move_rope entity.

Hey, I looked at your problem map also you said you wanted the map to be dark but its fullbright when you load it. Well if you havent added a light to level yet, when you load the game it automaticly turns full bright on. otherwise you wouldnt be able to see a damn thing hehe. Just add a little light entity in the corner or something but turn the brightness on it down.

Thanks LittleTortilla!
Everything works now..
But my map didn't have an intresting idea.. so I dumped it into the trashcan..


But I'll have use for your help in my new "almost no changes" mod; center of evil..

And thanks Blackravent for making an example map! =)

Sorry Iv been away to London for the past few days and I havnt been here I never tried the map so I didnt know it was craped, owell my first example map! It gives the general idea I just didnt move the pointy thing in the length constraint. And thanks anyway.

Iv now updated it and it should work.
