I'm trying to get the current camera position in my DLL. However, I'm not type casting it right or something because the data doesnt come in as a float. I can see it coming in and it changes, but the values are way wrong.

Here is my code, well at least the related lines.



ANybody have any ideas on what I'm doing wrong? IanM?

You need to store the result into a DWORD variable, then use some nasty casting to get the float value. You can't directly cast it as you are trying to do.



That's get the address of the DWORD, which has a type of pointer-to-dword, then cast it to pointer-to-float, then dereference the pointer to get the value.

Ah ha! That worked... your a genie! I kind figured that some reversal to the *(DWORD*)& method of passing the float back needed to happen. I tried that but I was doing it directly. Never thought of doing it indirectly.

Thanks!
