Phys pulleyconstraint

Description

A constraint that is essentially two length constraints and two points. Imagine it as a virtual rope connected to two objects, each suspended from a pulley above them.The constraint keeps the sum of the distances between the pulley points and their suspended objects constant.

Keyvalues

• Template:Kv targetname
• attach1 <target_destination>
• attach2 <target_destination>
• constraintsystem <target_destination>

The name of a phys_constraintsystem that this constraint should be a part of. All constraints on a set of entities should be placed in the same system, or they will fight each other during simulation.

• forcelimit <float>

The amount of force an impact must apply to the constraint to break it. A way of calculating this is to set it to the mass of an object that would break this constraint if it were resting on the constrainted objects.

• torquelimit <float>

The amount of torque required to break the constraint. A way of calculating this is to multiply any reference mass by the resting distance (from the center of mass of the object) needed to break the constraint.

• breaksound <sound>

A sound played when the constraint is broken.

• addlength <float>

Add (or subtract) this amount to the rest length of the pulley rope.

• gearratio <float>

Add (or subtract) this amount to the rest length of the pulley rope.

• position2 <vecline>

The position of the pulley for Entity 2. The pulley for Entity 1 is the origin of this constraint entity. Entity 1 is always suspended from pulley point 1, and Entity 2 is always suspended from pulley point 2.

Inputs

• Template:I targetname
• Break

Force the constraint to break.

• TurnOn

Enable the constraint. Do this when the objects don't exist when the constraint spawns - or when you have deactivated the constraint. Broken constraints can NOT be turned on. They have been deleted.

• TurnOff

Disable this constraint.

Outputs

• Template:O targetname
• OnBreak

Fired when the constraint breaks.
