the 1st sprite is animated

It will be alot easier to help you if you post some code.

int main()
{
........
InitializeSprites(); //set all sprites off screen (stops artifact)
sprites[0].attribute0 = COLOR_256 | SQUARE | green.y; //setup sprite info, 256 colour, shape and y-coord
sprites[0].attribute1 = SIZE_16 | green.x; //size 16x16 and x-coord
sprites[0].attribute2 = 0; //pointer to tile where sprite starts
for(loop = 0; loop < 1024; loop++) //load 1st sprite image data
{
OAMData[loop] = GREENData[loop];
}
green.activeFrame = 0; //set the initial active frame markers
green.spriteFrame[0] = 0; //set the frame markers
green.spriteFrame[1] = 8;
green.spriteFrame[2] = 16;
green.spriteFrame[3] = 24;
green.spriteFrame[4] = 32;
green.spriteFrame[5] = 40;
green.spriteFrame[6] = 48;
green.spriteFrame[7] = 56;
sprites[1].attribute0 = COLOR_256 | SQUARE | block.y;//setup sprite info, 256 colour, shape and y-coord
sprites[1].attribute1 = SIZE_16 | block.x; //size 16x16 and x-coord
sprites[1].attribute2 = 64; //pointer to tile where sprite starts
for(loop = 1024; loop < 1152; loop++) //load 1st sprite image data
{
OAMData[loop] = BLOCKData[loop-128];
}
...........
}

Are you sure that the loop-128 index is correct when you load the block sprite data?
A little tip: when you post code use the Code button.
Ex

| Code: |
for(loop = 1024; loop < 1152; loop++) //load 1st sprite image data
{
OAMData[loop] = BLOCKData[loop-128];

is this the only place where the problem could be ?
#22743 - Becks7 - Mon Jun 28, 2004 4:08 pm
cause i think it is correct
#22744 - poslundc - Mon Jun 28, 2004 4:13 pm
There is a high probability this is where the problem stems from. Where is BLOCKData defined? Try rewriting the code using GREENData instead.
But sure, the problem could lie elsewhere. We've only got a snippet of your code.

It looks to me like you just copied that bit from gbajunkie's tutorial(I could be wrong). Is your data setup up the same way as in his tutrial?
#22746 - Wriggler - Mon Jun 28, 2004 4:21 pm
Yeah it looks to me (as someone who is learning this exact thing right now!) that your "loop-128" index should be "loop-1024". That's assuming the BLOCKData stuff you want starts at the array index 0. Otherwise you are starting your image at index 896, which probably isn't right...

#22791 - Becks7 - Tue Jun 29, 2004 5:38 pm
yes, its from the gbajunkie tutorials but i have rewritten it acording to my game
i will try changing "loop-128" to "loop-1024"
#22862 - Becks7 - Wed Jun 30, 2004 4:50 pm
but, i dont think this would help, because i have eight character images above the block image
#22864 - poslundc - Wed Jun 30, 2004 5:15 pm
Like I said in my earlier post, it will depend largely on what BLOCKData is defined as. I don't know why you don't use GREENData instead.

#23068 - Becks7 - Sat Jul 03, 2004 9:32 am
GREENData is the green character (1st sprite)
BLOCKData is the block (2nd sprite)
the 2nd one is not displayed correctly as you can see from the pics
#23074 - poslundc - Sat Jul 03, 2004 1:40 pm
I meant in the code, not in your design. Of course everything works the way you want it to in your head.
