Function Documentation

retrotile_gen_diamond_square_iter()

MERROR_RETVAL retrotile_gen_diamond_square_iter	(	struct RETROTILE *	t,
		retroflat_tile_t	min_z,
		retroflat_tile_t	max_z,
		uint32_t	tuning,
		size_t	layer_idx,
		uint8_t	flags,
		void *	data,
		retrotile_ani_cb	animation_cb,
		void *	animation_cb_data
	)

Generate tilemap terrain using diamond square algorithm.

See retrotile_gen_cb() for details.

Warning

This can be very slow!

This will generate a complete new tilemap!

retrotile_gen_smooth_iter()

MERROR_RETVAL retrotile_gen_smooth_iter	(	struct RETROTILE *	t,
		retroflat_tile_t	min_z,
		retroflat_tile_t	max_z,
		uint32_t	tuning,
		size_t	layer_idx,
		uint8_t	flags,
		void *	data,
		retrotile_ani_cb	animation_cb,
		void *	animation_cb_data
	)

Average the values in adjacent tiles over an already-generated tilemap.

This is designed to be used with tilemaps that use their tile indexes as Z values rather than indexes in a table of tile definitions.

retrotile_gen_voronoi_iter()

MERROR_RETVAL retrotile_gen_voronoi_iter	(	struct RETROTILE *	t,
		retroflat_tile_t	min_z,
		retroflat_tile_t	max_z,
		uint32_t	tuning,
		size_t	layer_idx,
		uint8_t	flags,
		void *	data,
		retrotile_ani_cb	animation_cb,
		void *	animation_cb_data
	)

Generate tilemap terrain using voronoi graph.

See retrotile_gen_cb() for details.

This is more suitable for purely 2D tilesets, as the changes between indexes are very abrupt!

Warning

This will generate a complete new tilemap!
