class bge.types.KX_ConstraintWrapper

KX_ConstraintWrapper

getConstraintId(val)

Returns the constraint ID

Returns:

the constraint ID

Return type:

integer

setParam(axis, value0, value1)

Set the constraint limits

Parameters:

axis (integer)

Note

  • Lowerlimit == Upperlimit -> axis is locked

  • Lowerlimit > Upperlimit -> axis is free

  • Lowerlimit < Upperlimit -> axis it limited in that range

For PHY_LINEHINGE_CONSTRAINT = 2 or PHY_ANGULAR_CONSTRAINT = 3:

axis = 3 is a constraint limit, with low/high limit value

  • 3: X axis angle

Parameters:

  • (min) (value0) – Set the minimum limit of the axis

  • (max) (value1) – Set the maximum limit of the axis

For PHY_CONE_TWIST_CONSTRAINT = 4:

axis = 3..5 are constraint limits, high limit values

  • 3: X axis angle

  • 4: Y axis angle

  • 5: Z axis angle

Parameters:

  • (min) (value0) – Set the minimum limit of the axis

  • (max) (value1) – Set the maximum limit of the axis

For PHY_GENERIC_6DOF_CONSTRAINT = 12:

axis = 0..2 are constraint limits, with low/high limit value

  • 0: X axis position

  • 1: Y axis position

  • 2: Z axis position

axis = 3..5 are relative constraint (Euler) angles in radians

  • 3: X axis angle

  • 4: Y axis angle

  • 5: Z axis angle

Parameters:

  • (min) (value0) – Set the minimum limit of the axis

  • (max) (value1) – Set the maximum limit of the axis

axis = 6..8 are translational motors, with value0=target velocity, value1 = max motor force

  • 6: X axis position

  • 7: Y axis position

  • 8: Z axis position

axis = 9..11 are rotational motors, with value0=target velocity, value1 = max motor force

  • 9: X axis angle

  • 10: Y axis angle

  • 11: Z axis angle

Parameters:

  • (speed) (value0) – Set the linear velocity of the axis

  • (force) (value1) – Set the maximum force limit of the axis

axis = 12..14 are for linear springs on each of the position of freedom

  • 12: X axis position

  • 13: Y axis position

  • 14: Z axis position

axis = 15..17 are for angular springs on each of the angle of freedom in radians

  • 15: X axis angle

  • 16: Y axis angle

  • 17: Z axis angle

Parameters:

  • (stiffness) (value0) – Set the stiffness of the spring

  • (damping) (value1) – Tendency of the spring to return to it’s original position
