Use these blocks to create objects that are added to the bodylist and jointlist of a Box2d database used by the Physics Activity. Objects are positioned by the turtle x,y and colored based on the current pen attributes. From left to right:

* start polygon: use the current turtle x,y position to specify the first vertex of a polygon

* add point: use the current turtle x,y position to add a vertex to a polygon

* end polygon: use the current turtle x,y position to specify the last vertex of a polygon

* end filled polygon: use the current turtle x,y position to specify the last vertex of a ''filled'' polygon

* triangle: add a triangle object at the current turtle x,y position

* circle: add a circle object at the current turtle x,y position

* rectangle: add a rectangle object at the current turtle x,y position

* reset: reset bodylist and jointlist (clear all objects and reset default parameters)

* motor: add a motor at the current turtle x,y position (attached to the object at this position)

* pin: add a pin at the current turtle x,y position (attached to the object at this position)

* joint: add a joint between the object at the current turtle x,y position and the object at x, y

* density: set the object density (0 is light; 1 is heavy)

* friction: set the object friction (0 is slippery; 1 is sticky)

* bounciness: set the object restitution (0 is rigid; 1 is bouncy)

* save as Physics project: save the current bodylist and jointlist as a Physics project in the Journal
