You have to make the animation update through the class, I made an object class to play and loop animations like GDK used to.
CObject.h

It uses a struct to hold info about the model it is using. It is far from complete but the play and loop animation fuctions should work. You have to call CObject.animateObject(curTime) in the loop. Using it should look like this:
#include "DarkGDK.h"
#include "CObject.h"
void DarkGDK()
{
dbSyncOn();
dbSyncRate(60);
dbSetDisplayMode(1024, 768, 32);
CObject BadGuy;
BadGuy.Load("BadGuy.x", "BadGuy.dds");
BadGuy.SetFPS(60);
BadGuy.LoopAnimation(0, 100);
while (LoopGDK)
{
int curTime = dbTimer();
BadGuy.animateObject(curTIme);
dbSync();
}
return;
}
You will have to replace "ObjectResource->Pop();" and "ImageResource->Pop();" with your own resource mangment function or you can also use techlords:
