Hanging ragdolls: world of pain.

[Bikerdude]

Tring to get a ragdoll to stay attached to a hangmans rope, bothing Ive tried works. so started having a look on the forum -

but not found much help there or even an example prefab...

Do not hang ragdolls.

 

Use the ambient AI way presented here:

Doh, I forgot all about that thread!

LOL. I almost got a hanging ragdoll to work once...almost. Several hours were spent experimenting with which entity was bound to which, and encapsulating the ragdoll with thin nodraw_solid brushes until it didn't fall out of place (including thin shims under the armpits and crotch). The ragdoll eventually ended up twitching enough to throw the rope off angle, making it disconnect from the gallows. Lots of similar problems.

Necro'ing because I think I've got somewhere with this:

The way the noose looks isn't ideal: I had to scale it in DR in the first place, since the original obviously wasn't designed to go with the AI necks, and before I set the noose nonsolid the ragdoll would twitch around for a bit and then settle without a nicely drooping look. So you might want to continue using Sotha's anim (especially if you want a swinging-in-wind effect like in PD2, which this method won't allow). If you'd like a hanged ragdoll, though, this seems viable. Basically you take the modified AF below, save it as af/guard_base_newskel_hanged.af, and give the ragdoll an "articulatedFigure" "guard_base_newskel_hanged" spawnarg. This causes the head to be bound to the world, so it stays in position, but the rest of the body still has ragdoll physics (I also made it solid to the player).

I didn't know this was something you guys add problems with!  The Doom 3 game and Grimm (also using idtech 4) have hanged ragdolls, Grimm even use them to good effect to make simple dynamic cloth. The Doom 3 one (hanged by one feet) can even move about like a pendulum.   The trick like you found out is to bind the bone you want stuck to the world (with the AF editor).  But your method VanishedOne, even tho works, unfortunately makes the character unrealistically stuck in the world by the head.

Like you guys also found out, binding a ragdoll to another, doesn't not work (afaik) in idtech 4, it will just cause collision problems.

If you guys want to have realistic hanged ragdolls , that can be moved about realistically, than the only way I know (apart from animation...), is to make the rope part of the character rig (in Blender), in that way the body and rope will just be one single skeleton/ragdoll. 

Btw when you drag a dead AI character around you are essentially making a "hanged" ragdoll.

Quake 4 assets reference 'meat hooks' that appear to involve binding a ragdoll to an animated entity, but I'm not certain of the workings, especially a line in the ragdoll's script that uses bindConstraint.

[HMart]

Oh yes i know that scene in Quake 4, is where they have the marine corpses going around on conveyor belts in meat hooks for stroggification!

I was mistaken, is possible to attach a af to a animated object, In the script and specially in the c++ code you can bind a bone to anything (you can even animate bones with code). 

Btw the crane script in Doom 3 can give some clues on how to attach af objects to animated objects.

This particular piece of the script code, does the binding, you can see bindConstraint mentioned there and also the keyword "fixed" this last one says that is a fixed bind, instead of "fixed" you also have "ballAndSocket" that is what the dragentity tool uses (permits the af to move around) and imo should be used for a hanged ragdoll.

	if ( !( !bindEntity ) ) {
		return;
	}

	crane_have_object = false;
	bindJoint = bindBody = "";

	sound_crane_fingers_close();
	
	$crane.setFingerAngle( 20 );
	sys.wait( 2.0f );
	$crane.stopFingers();

	begin = $crane_trace_start.getWorldOrigin();
	end = $crane_trace_end.getWorldOrigin();

	sys.trace( begin, end, '0 0 0', '0 0 0', MASK_SOLID|CONTENTS_RENDERMODEL, $crane_hang );
	bindEntity = sys.getTraceEntity();
	if ( !( !bindEntity ) && ( bindEntity != $world ) ) {
		bindJoint = sys.getTraceJoint();

		if ( bindJoint ) {
			bindBody = sys.getTraceBody();
			if ( bindBody ) {
				bindEntity.setKey( "bindConstraint bind1", "fixed " + bindBody + " " + bindJoint );
				bindEntity.bindToJoint( $crane, "crane", 1 );
				crane_have_object = true;
			}
		} else {
			bindEntity.bindToJoint( $crane, "crane", 1 );
			crane_have_object = true;
		}
	}

	// automatically move up
	crane_move( $crane_hang, UP, crane_maxs_z - crane_pos_z, false );

	if ( !crane_have_object ) {
		sound_crane_fingers_open();
		$crane.setFingerAngle( -60 );
		bindEntity = $null_entity;
	} else {
		$main_control_gui.setGuiParm ( "gui_parm1" , 1);
	}
}

 

Btw looking at the c++ code that manages this in the dragEntity tool, it seems "bindConstrain bind" are both required, only the number changes in the c++ code.  so you need to say bind1, bind2, etc.

key.Strip( "bindConstraint " );
		if ( sscanf( key, "bind%d", &num ) ) {
			if ( num >= largestNum ) {
				largestNum = num + 1;
			}
		}
