SPR_releaseSprite breaks on large sprites

[Grind]

Best way to describe this is with code.

Code: Select all

// Load 2 large sprites (bigger than 4x4)
Sprite *spr[2] = {
    	SPR_addSprite(&SPR_Igor, 80, 80, TILE_ATTR(PAL2, 1, 0, 0)),
    	SPR_addSprite(&SPR_Balfrog, 160, 80, TILE_ATTR(PAL3, 1, 0, 0))
};

// Release and re-add first one
SPR_releaseSprite(spr[0]);
spr[0] = SPR_addSprite(&SPR_Igor, 80, 120, TILE_ATTR(PAL2, 1, 0, 0));
// Second sprite has been chopped

I haven't looked at the SPR_releaseSprite code but it seems to be freeing the wrong entries in the sprite list whenever a large sprite exists. This has caused very amusing behaviour, like half the HUD taking place of an enemy, and jumping spikes (scarier than the boss ).

Happy to say though that the laggy areas are running at 60 now.

Thanks fo the report, i found the problem Turn out that i forgot to update some pieces of my code (i made at least 3 complete different implementation of Sprite Engine and i had some part of code based on previous one).
Fix is pushed on github (sprite_eng.c file) but i will do a proper new SGDK release to address it !

Great, now it works perfectly! Keeping the old libmd.a around in case I want to entertain myself again
