Returns the id of the previous body, or 0 if there is no previous body.

• world_id: The id of the world.

• body_id: The id of the body.

ep_body_next

ep_body_next(world_id, body_id)

Returns the id of the next body, or 0 if there is no next body.

• world_id: The id of the world.

• body_id: The id of the body.

ep_body_set_uservar

ep_body_set_uservar(world_id, body_id, index, value)

Changes the value of the user variable with the given index.

• world_id: The id of the world.

• body_id: The id of the body.

• index: The index (0-4).

• value: The new value.

ep_body_get_uservar

ep_body_get_uservar(world_id, body_id, index)

Changes the value of the user variable with the given index.

• world_id: The id of the world.

• body_id: The id of the body.

• index: The index (0-4).

ep_body_first_shape

ep_body_first_shape(world_id, body_id)

Returns the id of the first shape connected to this body, or 0 if there are no shapes.

• world_id: The id of the world.

• body_id: The id of the body.

ep_body_last_shape

ep_body_last_shape(world_id, body_id)

Returns the id of the last shape connected to this body, or 0 if there are no shapes.

• world_id: The id of the world.

• body_id: The id of the body.

ep_body_shape_count

ep_body_shape_count(world_id, body_id)

Returns the number of shapes connected to this body, or 0 if there are no shapes. The body keeps track of the number of shapes internally so this function is very fast.

• world_id: The id of the world.

• body_id: The id of the body.

ep_body_first_force

ep_body_first_force(world_id, body_id)

Returns the id of the first force connected to this body, or 0 if there are no forces.

• world_id: The id of the world.

• body_id: The id of the body.

ep_body_last_force

ep_body_last_force(world_id, body_id)

Returns the id of the last force connected to this body, or 0 if there are no forces.

• world_id: The id of the world.

• body_id: The id of the body.

ep_body_force_count

ep_body_force_count(world_id, body_id)

Returns the number of forces connected to this body, or 0 if there are no forces. The body keeps track of the number of shapes internally so this function is very fast.

• world_id: The id of the world.

• body_id: The id of the body.
