Updated legacy sprite engine with latest features and fixes #333

Closed TheRoboZ closed 5 months ago

TheRoboZ commented 6 months ago

This implements:

SPR_setAlwaysAtBottom
SPR_setAutoAnimation
SPR_getAutoAnimation
SPR_setAnimationLoop
SPR_getAnimationDone

and fixes the empty frame bug in:

static void loadTiles(Sprite* sprite)

for the legacy sprite engine

COOL! Alas, we keep using our own wrapper around the basic SGDK funcs because even now it is not enough for a beat 'em up

Any chance of sharing the wrapper? This PR came from a plan to compare bot sprite engines for performance on r-type, if your wrapper performs even better, I'd gladly use it for an ad-hoc implementation for my engine.

We cannot share it (at least until Zabu is fully released). But the main thing in the wrapper is:

Animations have some meta data
Each frame animation has its own duration
