I'm beginning to suspect that this forum doesn't like me.
Any time I try to include something using the 'Code:' section, the code is non-displayable.
Any attempts to attach a zip file cause a non-forum specific error page when I submit the post. It states 'The page cannot be displayed'. The zip file is 936KB in size, under the specified maximum. I have tried in various browsers (including your basic Internet Explorer).
When I posted to the 'DarkSDK Bugs' thread, even though I can see my post in the page, the summary page doesn't indicate my post (in the 'Last Post@' column). I do a complete refresh regularly to see what comes up new and other posts trigger changss in 'Last Post@'. This appears be a bug in the forum software for threads that have more than one page. The same phenomenon can be observed in the 'SDK Update' thread.
A previous thread, using a more complete (ie. complex) version of the sample has had people some viewers, but no help or suggestions offered.
I would really like some help with my problem, or recognition that it is a bug (which will hopefully be fixed).
Here it is again:
I have run into two, possibly related, problems. Fixing either would allow me to build my games easier (I can brute force a solution, but would rather to it properly).
1. The dbLimbAngleY function does not return the proper value, even when the limb is clearly changing angle
2. The dbObjectPosition<X><Y><Z> and dbObjectAngle functions do not return values for an object that is glued to a limg, even when the object is moving
I will send the model and .Net project to anyone interested in looking into this.
The only headers needed are the standard DarkSDK and C++ ones. So this code is easily tested in VC6 as well.
The model was built with 3ds max 6 and converted to .x using Deep Exploration.
I have tested this under both Windows 2000 and Windows XP Pro, both with all the latest patches and both with the latest DirectX.
