Constructor & Destructor Documentation

Stg::Block::Block	(	Model *	mod,
		stg_point_t *	pts,
		size_t	pt_count,
		stg_meters_t	zmin,
		stg_meters_t	zmax,
		Color	color,
		bool	inherit_color
	)

Block Constructor. A model's body is a list of these blocks. The point data is copied, so pts can safely be freed after constructing the block.

Stg::Block::Block	(	Model *	mod,
		Worldfile *	wf,
		int	entity
	)

A from-file constructor

Stg::Block::~Block ( )

Member Data Documentation

CellPtrVec* Stg::Block::candidate_cells [private]

When moving a model, we test for collisions by generating, for each block, a list of the cells in which it would be rendered if the move were to be successful. If no collision occurs, the move is allowed - the rendered cells are cleared, the potential cells are written, and the pointers to the rendered and potential cells are switched for next time (avoiding a memory copy).
