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:
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:
* 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)
* start polygon: use the current turtle x,y position to specify the first vertex of a polygon
* 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
* add point: use the current turtle x,y position to add a vertex to a polygon
* gear: add a gear object at the current turtle x,y position with the number of teeth as the argument
* gear: add a gear object at the current turtle x,y position with the number of teeth as the argument
* motor: add a motor at the current turtle x,y position (attached to the object at this position)
* 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)
* pin: add a pin at the current turtle x,y position (attached to the object at this position) to prevent movement
* pen: add a pen at the current turtle x,y position (attached to the object at this position) to trace motion
* joint: add a joint between the object at the current turtle x,y position and the object at x, y
* joint: add a joint between the object at the current turtle x,y position and the object at x, y
* save as Physics project: save the current bodylist and jointlist as a Physics project in the Journal
* save as Physics project: save the current bodylist and jointlist as a Physics project in the Journal
