Type: LinearDOFSetup
Default value:
| Member | Value |
|---|---|
| bLimited | 1 |

Property group 'Pulley'[edit]
bIsPulley[edit]
Type: bool
bMaintainMinDistance[edit]
Type: bool
PulleyRatio[edit]
Type: float
Default value: 1.0
Property group 'RB_ConstraintSetup'[edit]
bEnableProjection[edit]
Type: bool
If distance error between bodies exceeds 0.1 units, or rotation error exceeds 10 degrees, body will be projected to fix this. For example a chain spinning too fast will have its elements appear detached due to velocity, this will project all bodies so they still appear attached to each other.
ConstraintBone1[edit]
Type: name
Name of first bone (body) that this constraint is connecting. This will be the 'child' bone in a PhysicsAsset.
ConstraintBone2[edit]
Type: name
Name of second bone (body) that this constraint is connecting. This will be the 'parent' bone in a PhysicsAset.
JointName[edit]
Type: name
Modifiers: const
Name of bone that this joint is associated with.

Structs[edit]
LinearDOFSetup[edit]
Modifiers: native
Struct specying one Linear Degree Of Freedom for this constraint. Defaults to a ball-and-socket joint.
- byte bLimited
- Whether this DOF has any limit on it.
- float LimitSize
- 'Half-length' of limit gap. Can shift it by fiddling Pos1/2.
A size of 0.0 results in 'locking' the linear DOF.
Default values:
| Property | Value |
|---|---|
| bLimited | 1 |
| LimitSize | 0.0 |
