pXcon_setmotor

pXcon_setmotor (void* constraint_ID, VECTOR* SteerAngle, VECTOR* MotorTorque, VECTOR* undefined );

This turns a static joint into a motorized one. For wheels the motor tries to rotate the entities with a given angular velocity. In order to reach the velocity specified by the user a certain amount of force or torque is required. Therefore the maximum amount of force/torque available also needs to be specified. If this value is very low objects might not start moving at all.

Parameters:

constraint_id	entity or unique identifier of the constraint to be configured
SteerAngle	X = rotate the Wheel for steering. Y = limit rotation Z = not used yet
MotorTorque	X = addTorque, Y = maximumTorque, Z = brakeTorque
undefined	not used yet - set to nullvector

Returns:

1 if successful, 0 otherwise.

Speed:

Fast

Examples:

...
ENTITY* wheel;
phcon_semotor(wheel, vector(steering,90,0), vector(direction*torque, MaxTorque, 0), nullvector);}
