Constraints Actuator

Adds a constraint to the location, orientation

See Actuator Common Options for common options.

Special Options:

Constraint Mode

Menu specifying type of constraint required.

• Force Field Constraint
• Orientation Constraint
• Distance Constraint
• Location Constraint

Constraint actuator - Force Field

Force Field Constraint

Create a force field buffer zone along one axis of the object.

Damping

Damping factor of the Fh spring force (Range 0.0 - 1.0)

Distance

Height of Fh area

Rot Fh

Make game object axis parallel to the normal of trigger object.

Direction

Axis in which to create force field (can be + or -, or None)

Force

N

When on, use a horizontal spring force on slopes

M/P

Trigger on another Object will be either Material (M) or Property (P)

Property

Property/Material that triggers the Force Field constraint (blank for ALL Properties/Materials)

Per

Persistence button

When on, force field constraint always looks at Property/Material; when off, turns itself off if it can't find the Property/Material.

Time

Number of frames for which constraint remains active

RotDamp

Damping factor for rotation

Constraint Actuator - Orientation

Orientation Constraint

Constrain the specified axis in the Game to a specified direction in the World axis.

Direction

Game axis to be modified (X, Y, Z or none)

Damping

Delay (frames) of the constraint response (0 - 100)

Time

Time (frames) for the constraint to remain active (0 - 100)

ReferenceDir

Reference direction (global coordinates) for the specified game axis.

MinAngle

Minimum angle for the axis modification;

MaxAngle

Maximum angle for the axis modification;

Constraint actuator - Distance

Distance Constraint

Maintain the distance the Game Object has to be from a surface

Direction

Axis Direction (X, Y, Z, -X, -Y, -Z, or None)

L

If on, use local axis (otherwise use World axis)

N

If on, orient the Game Object axis with the mesh normal.

Range

Maximum length of ray used to check for Material/Property on another game object (0 - 2000 Blender Units)

Force Distance

•Distance to be maintained between object and the Material/Property that triggers the Distance Constraint(-2000 to +2000 Blender Units).

Damping

Delay (frames) of the constraint response (0 - 100)

M/P

Trigger on another Object will be either Material (M) or Property (P)

Property

Property/Material that triggers the Force Field constraint (blank for ALL Properties/Materials)

Per

Persistence button: When on, force field constraint always looks at Property/Material; when off, turns itself off if it can't find the Property/Material.

Time

Number of frames for which constraint remains active

RotDamp

Damping factor for rotation

Constraint actuator - Location

Location Constraint

Limit the position of the Game Object within one World Axis direction. To limit movement within an area or volume, use two or three constraints.

Limit

Axis in which to apply limits (LocX, LocY, LocZ or none)

Min

Minimum limit in specified axis (Blender Units)

Max

Maximum limit in specified axis (Blender Units)

Damping

Delay (frames) of the constraint response (0 - 100)
