Thanks for the reply.

The problem with putting the objects in the same list is that they are two completely different objects with very different behaviors. For example, I am trying to hit the zombie with the truck but avoid the road debris, the zombie moves around and is animated where are the debris is static so I need separate lists for the zombie object and debris object. Otherwise, I would have have indeed used a Z or depth value as you suggested.

Also, the Zombie is taller than the debris objects but... I am returning the Y pos, not the size of the sprite. I also have an origin set up for each of the sprites which is the sprite texture height so at the bottom. So the Y position should relate to the very bottom of each sprite.

I figured it! And rather obvious when you think about it too.

I used a switch statement as you suggested and found that I was getting a D3DERR_INVALIDCALL. Went back and looked at the way in which I was initialising my parameters. Soon realised I was creating my sprite object before I ran my initDirectX method. So, in turn I wasn't actually loading any textures or positions in the first place when I thought I was.

Anyway, thanks for the help. Took a while but finally got there!

Hi, thanks for the reply.

I have checkted and the draw call is definitely failing and the return code I am getting is 1 (I have not been able to find a way of telling whether it is a D3DERR_INVALIDCALL or D3DXERR_INVALIDDATA error.

One thing I did think, when drawing a sprite to the screen, we must put the call to the draw() method in between:

</p><pre>
d3dSprite->Begin(D3DXSPRITE_ALPHABLEND);</pre>
// ...
 
<pre>
d3dSprite->End();</pre>

Am I correct in thinking I can just put the call to the objects draw method in between these two and it will still work?
