A hinge constraint in a physics world The jit.phys.hinge object restricts two additional angular degrees of freedom so an attached jit.phys.body object can only rotate around the hinge axis. This can be useful to represent doors or wheels rotating around one axis. Limits and Motor forces can be specified for the hinge. If only a single body is bound, it is constrained to a point in world space. Cycling '74 Jitter messages in TEXT_HERE TEXT_HERE connect to jit.phys.body 1 TEXT_HERE connect to jit.phys.body 2 TEXT_HERE dumpout TEXT_HERE Return attached objects to original position and remove forces Removes any current forces and returns the attached objects to their original position. Degree of strictness for position error correction Magnitude of the limit's position correction (default = 0.3). This attribute sets how strictly the position error is corrected. For most cases, the value should not be greater than 1. First body to constrain The name of the first jit.phys.body to constrain. Second body to constrain The name of the second jit.phys.body to constrain. Collision enable Enables collisions between attached bodies (default = 0.). Enable simulation Enable this constraint in the physics simulation (default = 1). Hinge angle The angle, in degrees, between constrained bodies around the hinge axis (default = 0). Lower limit of allowed rotation The lower limit, in degrees, of allowed rotation around the hinge axis (default = 1). If lowerlimit is greater than upper limit, no limits are applied to the constraint. Maximum motor impulse The maximum motor impulse (default 1.). Angle (degrees) around hinge axis Angle around hinge axis, in degrees, the motor is targeting (default = 0). Motor enable/velocity Enables motor and specifies velocity desired in degrees per second (default = 0). Pivot point of body1 as a 3D vector The pivot point of body1 as a 3D vector relative to the body1 center of mass (default = 0 0 0). Pivot point of body2 as a 3D vector The pivot point of body2 as a 3D vector relative to the body2 center of mass (default = 0 0 0). If body2 is blank, this is the worldspace position of the constraint. Quaternion orientation of body1 relative to the hinge constraint The quaternion orientation of body1 relative to the hinge constraint (default = 0 0 0 1). Default value sets hinge axis to z axis. Quaternion orientation of body2 relative to the hinge constraint The quaternion orientation of body2 relative to the hinge constraint (default = 0 0 0 1). Default value sets hinge axis to z axis. If body2 is blank, this is the worldspace orientation of the constraint. Rate that velocity errors are corrected by limits The rate at which velocity errors are corrected by limits, effectively the strength of the limits (default = 1.0) . Lower values specify weaker limits. For most cases, the relaxation value should not be greater than 1. Rotation of body1 relative to the constraint Rotation of body1 relative to the constraint (default = 0 0 0 1). Default value sets hinge axis to z axis. Rotation of body2 relative to the constraint Rotation of body2 relative to the constraint (default = 0 0 0 1). Default value sets hinge axis to z axis. If body2 is blank, this is the worldspace orientation of the constraint. Euler rotation of body1 relative to the constraint Euler rotation of body1 relative to the constraint (default = 0 0 0). Default value sets hinge axis to z axis. Euler rotation of body2 relative to the constraint Euler rotation of body2 relative to the constraint (default = 0 0 0). Default value sets hinge axis to z axis. If body2 is blank, this is the worldspace orientation of the constraint. Constraint strength value Set the constraint strength (default = 0.2). Determines what proportion of the joint error will be fixed each simulation step. Values between 0.1 and 0.8 are recommended. Constraint stretch value Set the constraint stretch (default = 0.0). Setting to a positive value allows forces acting on rigid bodies to violate the constraint by an amount proportional to the stretch value. Upper limit of allowed rotation The upper limit, in degrees, of allowed rotation around the hinge axis (default = -1). If lowerlimit is greater than upper limit, no limits are applied to the constraint. Name of the context the constraint is bound to The name of a jit.phys.world context this constraint is bound to. The derived world position The derived constraint world position (default = 0 0 0) The derived world quaternion The derived constraint world quaternion (default = 0 0 0 1)
