Game Development How to Make a Video Game Player Input and Cameras Create a Target Rotation

Why or when exactly gets the hopping animation triggered?

As far as I understood we just change the property Speed. Is the animation inside of the player prefab and gets triggered when the Speed property has a certain value?

My second question: Why can we just use the arrow keys to move our frog? Don't they need to be initialized as input keys inside of the code? Or are they initialized in the parent (MonoBehaviour) class?

Hello Yassin,

Great questions!

To your first question, the hop animation and its trigger are a part of the Player prefab. If you open the PlayerController uner the Animations folder, you can see a diagram of the animations and view their trigger conditions.

Here's a screenshot that shows the Idle to Hop trigger where the animation will happen when the speed is greater than 0.5. If I change this value to any value over what is used in the course, 10 for example, the frog will no longer jump when I use the arrow keys because we're setting the speed to 3.

And to your last question, every Unity project has default input axes. You can view these in Unity by going to Edit -> Project Settings -> Input. By default, Horizontal and Vertical axes are mapped to w, a, s, d and the arrow keys. You can find more information about input defaults here.

I hope this helps.
