Functions and structures for working with tilemaps/grids.

Macro Definition Documentation

#define RETROTILE_CLASS_TABLE ( f )

Value:

   f( TILE,    tile,    0 ) \
   f( MOBILE,  mobile,  1 ) \
   f( WARP,    warp,    2 ) \
   f( ITEM,    item,    3 ) \
   f( CROP,    crop,    4 )

#define retrotile_clear_tiles	(	t,
		layer,
		i
	)

Value:

memset( retrotile_get_tiles_p( layer ), -1, \

(t)->tiles_w * (t)->tiles_h * sizeof( retroflat_tile_t ) )

int16_t retroflat_tile_t

Value for an individual tile in a RETROTILE_LAYER.

Definition: retroflt.h:19

#define retrotile_get_tiles_p ( layer )

Value:

((retroflat_tile_t*)(((uint8_t*)(layer)) + \

sizeof( struct RETROTILE_LAYER )))

Definition: retrotil.h:198

Value for an individual tile in a RETROTILE_LAYER.

This is defined early on so that it can be used in some other modules.
