Okay I made a few changes to my program, but it still doesnt work. I was just wondering if maybe someone else had a similiar tile engine and could maybe spot a problem with my code. The tiles move one tile at a time, but not smoothly. Anyone see anything wrong?


for(int y=0;y<numtilesy+1;y++)
	{
		for(int x=0;x<numtilesx+1;x++)
		{
			//mapspritedraw();

			int scrollx=worldx/tiledimx;
			int scrolly=worldy/tiledimy;

			offsety=scrolly % tiledimy;
			offsetx=scrollx % tiledimx;

			tilecoord.x=(x*tiledimx)-offsetx;
			tilecoord.y=(y*tiledimy)-offsety;

			TileLookUp(97,32,32,map[scrolly+y][scrollx+x],rect);
			mapsprite.Draw(anobject->pTexture,▭,NULL, NULL, 0.0f,&tilecoord,0xffffffff);
		}
	}

I think instead of:

offsety = scrolly%tiledimy;
offsetx = scrollx%tiledimx;

try this:

offsety = worldy%tiledimy;
offsetx = worldx%tiledimx;

I tried your suggestions and for some reason its still not scrolling. Its hard to think through how all the tiles are being effected each frame. For something seemingly so simple its actually pretty hard.

Do you think you could post more of your source? It scrolled fine for me when I adopted it to work with a program I made a while ago.
