Phys pulleyconstraint

Description

A constraint that is essentially two length constraints and two points. Imagine it as a virtual rope connected to two pulleyed objects, specified in the Entity 1 (attach1) and Entity 2 (attach2) keyvalues, each suspended from a pulley above them.

Pulley point 1 - the pulley from which Entity 1 is always suspended from - is the origin of this constraint entity.

Pulley point 2 - the pulley from which Entity 2 is always suspended from - is the position of the "blue ball", set by altering the Pulley Position 2 (position2) keyvalue directly, or by using the Helper Tool.

The constraint keeps the sum of the distances between the pulley points and their suspended objects constant.

Keyvalues

• Template:Kv twoobjectphysics
• 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>

Pulley Position 2 - The position of the pulley for Entity 2. This point can be set by using the Helper Tool.

Flags

• Template:Fl twoobjectphysics1
• 2 : Keep Rigid

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.
