Animation (Jump + Fall + Landing)

Hello everyone,
I'm trying to realise my first game in unity but I'm struggling with the animation.
Here is what I want:
- When the player is not grounded, display falling animation, then landing animation.
- When the player is grounded and jumps, display jump animation, then falling animation, and then landing.

I've joined a capture of what I've done.
It is not working because the falling animation is calling each frame and not playing completely.

 

Please consider this article on 2D animation methods. For a 2D game like this, I find using Unity's Animation Controller system in the standard way to be the most difficult approach. But in the article above you can compare three approaches, and see for yourself. You can also download a demo project with working run, jump, fall, and land.

 

can you point out were this demo is plaese

 

It's at the bottom of the article at the link you quoted.
