FIELDSTG_selectMap()

s32 FIELDSTG_selectMap

(

s32

index

)

Points the map at the file of map index: the grid, whose first two bytes are its width and height, the levels of cells and the pixels, at the offsets the file's entry starts with.

map.c

Returns 0 when no file is set. The match depends on the file's check being an early exit, a do-while (0) that breaks once the file is set, with file declared in it: the block's note stops stmt.c from rolling the exit test to the loop's end, and the loop notes keep the prologue's stores of ra and s0 ahead of the load in the second scheduler.

pos

)

Whether nothing stands at pos: no character's box (gathered once a frame) and no object.

The match depends on the two widths, the gathered box's and the tested one's, being variables of their own: one width for both blocks gives GCC 2.8.1 other registers.
