Horror Game: Creating a Matinee to open door
I have created a matinee to open the door of the bedroom. I added a Matinee into the scene. I then selected the door and in the Matinee window added New Empty Group and then a New Movement Track. I added the keyframes in for the movement of the door. I then tested this by playing the matinee and watching the door in the viewport. It worked correctly.
Next I created a trigger box and placed it in the radius of the door, so that it would open when the player gets close to it.
