sprite2mem and animsprite

[ampos]

Can I sent a frame of a animated sprite to mem?

if I do a matrix to store diferent "mem" and use it to "mem2sprite"? I mean:

Code (glbasic) Select Expand

dim m[24*24 size][10 frames]
mem2sprite m[][frame],spritenumber

With animated sprites, it will do the complete set of frames and not a single one.

In my game, when snowing there is around 640 sprites (5x5).

On iphone4 runs at 60fps, on 3GS at 30-40 and on 3G around 10-30 (yes, very irregular)

So I try to create a 480x320 sprite and dim bk[480x320].

Code (glbasic) Select Expand

for each drop
   bk[y*480+x]=0xffffffff
next
mem2sprite bk[],spr,480,320

This full loop has to be called each frame, and for my surprise, it is A LOT SLOWER than

Code (glbasic) Select Expand

for each drop
   drawsprite spr,x,y
next


havent noticed any difference using alphamode -1 or alphamode 0

It would be - MEM2SPRITE is somewhat slow - its not suitable for use in a game loop.
