Game freezes

[arczi84]

Hi,
I'm having issue on Amiga 68k port (Big Endian).
Game freezes in fifth level LOLIDRA'S CAVE.
I'm in location when there are 3 enemies that dissapear and when they do game freeze.

OK, found the code. Seems rand() issue on Amiga.

The function rand() cause the freeze?

[arczi84]

Game loops if it is run on low end cpus. For example when enemy wizard disappears.

Oh, I see. Sounds bad. Did you find a fix or wrokaround?

[arczi84]

I'll try to optimize game first. If that won't help I'll make some workaround.

[arczi84]

Overall looks like rand() issue, yes.

Not sure again.

collisionTiles[gridX][gridY] is alwas same as collisionTiles[gridX][gridY+1]
therefore it never breaks the loop and gridY is always 2.

wizard.c
			do {
				gridX = (rand() % 16)+ 1;

			} while (collisionTiles[gridX][gridY] != 0 ||
			             collisionTiles[gridX][gridY+1] != 1 ||
			             gridX == lastGridX);

I have to investigate...

Setting gridY to 3 worked for me.
Maybe lower FPU precision issue.

I still haven't looked into this. But glad you found some workaround!
