A rigid body and collision shape The jit.phys.body object represents a rigid body and collision shape in a physics simulation. The collision shape is either one of several simple shapes, a compound shape (combination of simple shapes), or defined by a matrix of vertices. Cycling '74 Jitter messages in TEXT_HERE TEXT_HERE connect to bind objects or position/quat values TEXT_HERE dumpout TEXT_HERE Update the body Update the body forces and matrix inputs, and output position and quat values. Add child shape to compound body Add to a compound body a child shape. Optional args are position x/y/z, quaternion x/y/z/w and scale x/y/z. Send compound shape description as dictionary Send a dictionary description of the compound body child shapes out the dumpout. Apply an impulse Apply an impulse (instantaneous force) to the rigid body using a worldspace vector described by x, y, z. If forces_relative is enabled, the vector is converted to object space. Optional args relative-x, relative-y, relative-z describe a relative position on the body where the force is applied, otherwise it's a central force. Remove child shape Remove the child shape at index from a compound body. Remove all child shapes Remove all child shapes from a compound body. Reset body properties Reset body properties position, and quat, and zero all forces. Set child shape position Set the position of child shape at index of a compound body. Set child shape quaternion Set the quaternion of child shape at index of a compound body. Set child shape scale Set the scaling factor of child shape at index of a compound body. Set child shape Set the shape of child at index of a compound body. Set the reset attributes to their current state Set the resetpos and resetquat attributes to their current state. Apply a torque impulse Apply a torque impulse (instantaneous angular force) to the rigid body using a worldspace vector described by x, y, z. If forces_relative is enabled, the vector is converted to object space. Name of parent jit.anim.node object The name of a jit.anim.node object to receive transform updates from. Collision reporting enable Enables and disables collision reporting out the second (dumpout) outlet. Linear and angular damping Set the linear and angular damping applied to a body in the range 0. to 1. (default 0.2 0.2). Damping can be used to simulate air resistance. Enable simulation Enable this body in the physics simulation (default = 1). Enable sleeping Enable sleeping on this body, causing deactivation when linear and angular velocity are 0 (default = 0). Name of this object's collision filter-class. Set the name of this object's collision filter-class (default = default). Other objects must specify the filterclass name in their filters list to enable collisions with this object. Maximum allowed unique names is 10. List of filterclass names this object collides with Specify a list of filterclass names to enable collisions with (default = all). Possible values include all, worldbox, and default. Additional values include any user-specified filterclass names (maximum allowed = 10). Apply force Apply a force to the rigid body using a 3D worldspace vector (default = 0 0 0). If forces_relative is enabled, the vector is converted to object space. Forces relative flag Forces relative flag will cause all forces to be converted to object space before applying (default = 0). Friction amount The friction amount (opposite force) (default = 0.5). Applied when the body is in contact with another body that has friction. Kinematic flag to remove dynamics on body Kinematic flag (default = 0). Use this mode to disable dynamics on the body, maintain collisions with other bodies in the world, and animate using position and quat attributes. This allows for a user-animated rigid-body. Local scaling flag Local scaling flag (default = 0). When enabled, the scale attribute will apply a local scaling transform to the collision shape. When disabled, the rigid-body is removed and re-added to the physics world for every scale modification. Body mass Body mass (default = 1.). When set to 0. body dynamics are disabled, however collisions remain active. Instance name Specifies the name of the instance (default = UID). Body position Body position in worldspace in the form x y z (default = 0. 0. 0.). Body orientation as quaternion Body orientation as a quaternion in the form x y z w (default = 0. 0. 0. 1.). Reduce convex hull flag Enable automatic vertex reduction when body shape attribute is set to convexhull (default = 1). Body reset position Body reset position in the form x y z (default = 0. 0. 0.). This is the worldspace position the body will return to upon receiving the reset message. Body reset orientation Body reset orientation as a quaternion in the form x y z w (default = 0. 0. 0. 1.). This is the orientation the body will return to upon receiving the reset message. Restitution value Restitution value, or bounciness (default = 0.1). The proportion of kinetic energy preserved on impact with other rigid bodies. Rolling friction amount The rolling friction amount (opposite force for a rolling object) (default = 0.0). Applied when the body is in contact with another body that has friction. Body orientation as angle-axis Body orientation as angle-axis in the form angle(in degrees) x y z (default = 0. 0. 0. 1.).

Body scaling factor The body scaling factor in the form x y z (default = 1. 1. 1.). Send scale flag Send scale flag (default = 1). When enabled, scale values will be sent to bound objects. Collision shape type Collision shape type (default = sphere). TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE Requires a matrix of vertices. A convex hull is generated that encloses the vertices. TEXT_HERE Requires a matrix of vertices. A concave shape is generated, allowing for hollows in the mesh shape TEXT_HERE Composite of simple shapes TEXT_HERE Requires a matrix of vertices. Handles dynamically changing mesh shapes and requires a non-moving rigid body. TEXT_HERE Target object name The name of a target object, either an OpenGL object or a jit.anim.node. This object will receive position, quat, and possibly scale values. Apply torque Apply a torque (angular force) to the rigid body using a 3D worldspace vector (default = 0 0 0). The current total force The total force currently applied to the rigid-body. The current total torque The total torque currently applied to the rigid-body. The current rigid-body velocity The current rigid-body velocity in units per second (default = 0 0 0). The current rigid-body angular velocity The current rigid-body angular velocity in radians per second (default = 0 0 0). Name of the context the body is bound to The name of a jit.phys.world context this body is bound to. Shapes defined by a mesh of vertices include convexhull, concave, and dynamicmesh. Each of these shapes require a 3 plane, float32, 1D or 2D matrix passed in. If the vertex matrix is 1D it's interpreted as a triangle mesh, if 2D it's interpreted as a tri_grid mesh.
