|
|
A constraint actuator limits the position, rotation, distance or orientation of an object.
|
|
|
|
Properties:
|
|
|
|
@ivar damp: time constant of the constraint expressed in frame (not use by Force field constraint)
|
|
@type damp: integer
|
|
|
|
@ivar rotDamp: time constant for the rotation expressed in frame (only for the distance constraint)
|
|
0 = use damp for rotation as well
|
|
@type rotDamp: integer
|
|
|
|
@ivar direction: the reference direction in world coordinate for the orientation constraint
|
|
@type direction: 3-tuple of float: [x,y,z]
|
|
|
|
@ivar option: Binary combination of the following values:
|
|
Applicable to Distance constraint:
|
|
KX_ACT_CONSTRAINT_NORMAL ( 64) : Activate alignment to surface
|
|
KX_ACT_CONSTRAINT_DISTANCE ( 512) : Activate distance control
|
|
KX_ACT_CONSTRAINT_LOCAL (1024) : direction of the ray is along the local axis
|
|
Applicable to Force field constraint:
|
|
KX_ACT_CONSTRAINT_DOROTFH (2048) : Force field act on rotation as well
|
|
Applicable to both:
|
|
KX_ACT_CONSTRAINT_MATERIAL ( 128) : Detect material rather than property
|
|
KX_ACT_CONSTRAINT_PERMANENT ( 256) : No deactivation if ray does not hit target
|
|
@type option: integer
|
|
|
|
@ivar time: activation time of the actuator. The actuator disables itself after this many frame.
|
|
If set to 0, the actuator is not limited in time.

|
|

|
@ivar distance: the target distance of the distance constraint
|
|
@type distance: float
|
|
|
|

|
|
