I want to make a futuristic sliding door.So I have a framing and two parts inside.I want to know how to animate the two parts moving in oposite positions so the door opens.
You need to keyframe your objects. In the timeline go to frame 0 and set your objects so as the door is shut, then select each object, press I > Location. This defines the start of the animation. To get the door to open, in the timeline set the current frame to 50 (if you want your door to open in 2 seconds) and repeat the first process excepted this time you must set the door open before adding the keyframes. Play the animation: the door opens.
