Template:Base point It is 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
- Additional Length ([todo internal name (i)]) <float>
- Add (or subtract) this amount to the rest length of the pulley rope.
- Pulley Gear Ratio ([todo internal name (i)]) <float>
- Add (or subtract) this amount to the rest length of the pulley rope.
- Pulley Position 2 ([todo internal name (i)]) <vector>
- 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.
TwoObjectPhysics:
- Entity 1 (attach1) <targetname>
- Entity 2 (attach2) <targetname>
- The entities to constrain. Leave one or the other field blank to constrain to the world.
Note:Only one entity will be constrained, even if several share the given targetname.
- Constraint System Manager (constraintsystem) <targetname>
- A phys_constraintsystem that this constraint should be a part of. This avoids the "jiggling" caused by constraints applied to the same set of entities fighting with each other.
- Force Limit to Break (forcelimit) <float>
- Impact force required to break the constraint, in pounds. 0 means infinite. A way of calculating this is to set it to the weight of an object that would break the constraint if it were resting on its objects.
- Torque Limit to Break (torquelimit) <float>
- Torque required to break the constraint, in pounds*inches. 0 means infinite. 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.
- Play Sound on Break (breaksound) <string>
- A sound played when the constraint is broken.
- Follow teleport distance (teleportfollowdistance) <float>
- If one constrained object teleports more than this many units away, the other will teleport with it.
Flags
- 1 : No Collision until break
- 2 : Keep Rigid
- No Collision until break : [1]
- Start inactive : [4]
- Change mass to keep stable attachment to world : [8]
- Do not connect entities until turned on : [16]
Inputs
TwoObjectPhysics:
- Break
- Force the constraint to break.
- TurnOn
- Enable the constraint; do this if the constrained objects don't exist when it spawns. Note that broken constraints cannot be turned back on as they have been deleted.
- TurnOff
- Disable the constraint.
Outputs
TwoObjectPhysics:
- OnBreak
- Fired when the constraint breaks.
