Multiple animations on mouse click?

Hello peoples, I am hoping this is a simple task. I have a char. rigged and a few animations. I am better 3d artist then programmer lol. Never the less they all worked correctly inside unity. Now I am wondering this.

When my main char get close to the “enemy” with animations, How can I cycle through multiple animations with/on mouseclick? I’m gonna use a trigger so it only happens when the Player is near the enemy. Perhaps an array of kinds? I’m not sure! anyone know?

Edit: I feel I should mention the animations are humanoid, not sure if that makes a difference.

I think the Animator in Unity is designed for this, and you can refer to the document. Any question you can comment behind this:)
