I'm trying to animate a door turning and I've successfully created the keyframes by using rotate on the X-Y axis around my 3D cursor. I've created start and end keyframes that are fine: enter image description here

enter image description here

note how both have the end fixed on the 3d cursor, my pivot point. However, the animation has the door poking out, for lack of a better word, 'escaping' the hinge.

enter image description here

It rotates and changes location, making it jut out and snap back again. I've tried adding more keyframes in the middle to fix its position, but then I can't control the easing...

I'm very new to blender and animation, so I'm not sure how to proceed >< Is there a setting to sort of 'fix' the door to the 'hinge' or pivot point during animation? Any help would be so much appreciated!

You can either change the pivot point as moonboots suggests, or (if you need the pivot point to stay elsewhere for other reasons) you can

  1. Add an Empty on the desired axis of rotation

    enter image description here

  2. Select the door, then Shift+Select the Empty, and CtrlP Set Parent to Object

  3. Animate the Empty, not the door

    enter image description here

(this is a very common procedure for rotating a camera around a scene by using an Empty)

When you animate, it doesn't take the 3D Cursor into account anymore, it will rotate around the object origin, or around the bone to which your object will be parented (or empty as suggested by Nicola Sap). So if you want your door hinge as a pivot point, you need to change the door origin and put it on its hinge: in Edit mode, select a hinge vertex, press shiftS > Cursor to Selected, then back in Object mode, press shiftctrlaltC > Origin to 3D Cursor (for 2.8: Header menu > Object > Set Origin > Origin to 3D Cursor). Then create your animation, your door should pivote around its hinge.
