[TIGCC] C strange 16x16 sprite error?

(1/3) > >>

bfr:
For some reason, I get the following error only when I do something for a 16x16 sprite - it doesn't happen with 8x8 or 32x32.

Incompatible type for argument 4 for 'Sprite16'.

Here's the code:

sprite16.c

c1-->CODE ec1
#include
#include "spinit.h"

unsigned short int sprite;

void _main(int x, int y, int height, char* variable, char* plane, char* method){
   if(variable=="a16"){
 

Ranman:
The function prototype for Sprite16 is:

c1-->CODE ec1void Sprite16 (short x, short y, short height, unsigned short *sprite, void *vm_addr, short mode); c2ec2

The 4th parameter is an "unsigned short *" not an "unsigned short". It is expecting you to pass in a pointer to an unsigned short. This pointer is the address of the sprite data.


Another thing to remember:

Both Sprite16 and Sprite32 expect the sprite data to begin on an even memory address. If you attempt to pass in an odd address to them, you will get a memory violation.

Thanks.  =)

I'm always making mistakes like these...:dang:

how is this possible?  how would you know if the address was odd/even?
