Is there any way I can import for instance a sword I made in Blender that is a separate .blend into a different .blend scence.
But, this is not really related to the game engine. Why did you post this here?
Press shift+F1 to append, then go to the .blend containing your sword, then click objects, then click on the sword object to import your sword.
well it is for a game. my example was just an example and thanks to you and blenderage for the quick replies.
