Entity Description

A physical constraint between two physically simulated objects. If one object is not specified then the respective end of the constraint will be anchored to the world.

Note:Objects will rotate around their ends with this entity. If you don't want them to do that, use a different constraint.

Keyvalues

• targetname

<target_source> The name that other entities refer to this entity by.

• Template:KV angles
• attachpoint

<vecline> Attached object 2 point - At what coordinates its "blue blob" (attachment point?) is at.

• attach1

<target_destination> Entity 1 - Entity that is anchored to the centerpoint of the constraint.

• attach2

<target_destination> Entity 2 - Entity that is anchored to the origin of the constraint.

• constraintsystem

<target_destination> Constraint System Manager - 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> Force Limit to Break (lbs) - 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> Torque Limit to Break (lbs * distance)? - 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

Play Sound on Break - A sound played when the constraint is broken.

• addlength

<float> Additional Length - Add (or subtract) this amount to the rest length of the rope.

• minlength

<float> Minimum Length - If the constraint is not rigid, this is the minimum length it can be.

Flags

• 1 : No Collision until break
• 2 : Keep Rigid
• 4 : Start inactive
• 8 : Change mass to keep stable attachment to world

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

• OnUser1-4

Fired in response to FireUser1-4 inputs. See User Inputs and Outputs.

• OnBreak

Fired when this breakable breaks.
