So I appended a group of objects to my level in BGE, but every time I reopen it (the level) the appended groups go back to the location at which they are saved in their own individual files. How do I get the groups of objects to remain where I put them in the level? Thanks.
Not sure you'll need to muck around with the Graph Editor - Try this first...
Select the main armature or whatever it's parented to.
Press SH-S --> Cursor to selected.
SH-A and add an Empty. (It will appear at the the same origin/pivot point as the armature or parent)
Parent the armature (or parent) to the Empty, choose "Object (keep transform)"
Drag the empty around and the model should follow it. Place it somewhere. Run the animation.
It should do it's thing but now from it's new location.
