Detailed Description

Sprite structure used by the Sprite Engine to store state for a sprite.
WARNING: always use the SPR_addSprite(..) method to allocate Sprite object.

Parameters:

status	Internal state and automatic allocation information (internal)
visibility	visibility information of current frame for each VDP sprite (max = 16)
spriteDef	Sprite definition pointer
onFrameChange	Custom callback on frame change event (see SPR_setFrameChangeCallback(..) method)
animation	Animation pointer cache (internal)
frame	AnimationFrame pointer cache (internal)
animInd	current animation index (internal)
frameInd	current frame animation index (internal)
timer	timer for current frame (internal)
x	current sprite X position on screen offseted by 0x80 (internal VDP position)
y	current sprite Y position on screen offseted by 0x80 (internal VDP position)
depth	current sprite depth (Z) position used for Z sorting
attribut	sprite specific attribut and allocated VRAM tile index (see TILE_ATTR_FULL() macro)
VDPSpriteIndex	index of first allocated VDP sprite (0 when no yet allocated) Number of allocated VDP sprite is defined by definition->maxNumSprite
lastVDPSprite	Pointer to last VDP sprite used by this Sprite (used internally to update link between sprite)
lastNumSprite	the number of VDP sprite used by the current frame (internal)
spriteToHide	internal
data	this is a free field for user data, use it for whatever you want (flags, pointer...)
prev	pointer on previous Sprite in list
next	pointer on next Sprite in list
