Overview

In another recipe, we use Grabbables and Joints to make a car’s doors openable (see Car Door with Behaviour Model). This approach is not as great for the trunk, however, as most trunks are automated and open with a click. In this recipe, we’ll create Unity animations that automatically open and close the rear door.

Create the Animations

This document assumes you have a basic understanding of Unity’s animation system and can create simple animations. This is a good starting point if not:https://docs.unity3d.com/Manual/AnimationSection.html

We’ll create two Animation Controllers that use the same clip to open and close the door. The “close” controller simply plays the clip backwards. We won’t walk through the creation step here, but here is what the two Animator Controllers look like:

...

Note that this one uses the same animation clip, but played with speed -1. For testing, make sure these two Animators are stored in a Resources folder so that they can be targeted by StoryFlowStoryflow:

Note that animations like these can also be deployed as an Asset Bundle, but for testing it’s quickest to load them directly from the Resources folder.
