Ugh... really stupid error, please someone help

This is very stupid.. Without ever changing the data, an array's values change. Let me show you what I mean: void MakeAnimation(SPRITEPTR sprite, int animindex, int numframes, int anim[]) { fprintf(fp2,"%d\n",sprite->anims[0][0]); fprintf(fp2,"%d\n",sprite->anims[0][1]); sprite->anims[animindex]=anim; sprite->curanimframes=numframes; sprite->indexinanim=0; } Ok, the one above me puts 0\n1\n0\n1\n (not really the \n, but you understand) this is the correct data. However, void UpdateSprite(SPRITEPTR sprite) { fprintf(fp2,"%d\n",sprite->anims[0][0]); fprintf(fp2,"%d\n",sprite->anims[0][1]); if(sprite->counter==sprite->updatecounter) { sprite->indexinanim++; if(sprite->indexinanim>sprite->curanimframes) sprite->indexinanim=0; sprite->curframe=sprite->anims[sprite->curanim][sprite->indexinanim]; sprite->counter=0; } sprite->counter++; } Produces: -858993460 -858993460 0 -858993460 0 2 0 2 0 2 0 1 -858993460 -858993460 0 -858993460 I'm not sure where this starts repeating, but I don't understand. You don't have to pay any attention to anything except what it fprintf s. This doesn't make any sense! I did a search for sprite->anim[ and only these places come up. Anyone have any clue how this can change inbetween this time? Ugh.. this is really irritating.. *EDIT* I'm sorry! haha! I forgot to mention something that makes this even more peculiar: Only the enemies do this, the normal spaceship works fine! How can this be? Also to add, before I added in animations for the enemies, this also worked fine, but I never called UpdateSprite or MakeAnimation, so who knows.. Edited by - Muzlack on February 18, 2002 9:55:51 PM

...And you use of fprintf is correct. My mistake there.

I''m not sure where you don''t understand, but I''ll do my best to explain: inside the sprite struct there is a 2 dimensional array called anims. I am sending the second dimension through MakeAnimation(). There is no problem with this because:

  void MakeAnimation(SPRITEPTR sprite, int animindex, int numframes, int anim[]) {		sprite->anims[animindex]=anim;	fprintf(fp,"%d\n", sprite->anims[0][0]);	fprintf(fp,"%d\n", sprite->anims[0][1]);	sprite->curanimframes=numframes;	sprite->indexinanim=0;}

Produces the correct animation (0,1)
Sorry, its something in between MakeAnimation & Update sprite, or it is updatesprite

AHA!!! I have figured it out. I don''t understand why, but, I can''t change the values of the enemies unless in the WinMain, I did a bunch of trial and error to see where the problem was, it was inbetween initenemies() and startup(), could I get an explanation why? I did fix the problem though.
