Questions & Answers

I’m new to scripting games. I want to know how to add new animations to a downloaded animator and controller script.

The animator does not have a jump animation. I added the animation but do not know how to add it to the script so it can be active in the controller.

The Mecanim animator controller is a state machine - you don’t “add animations to a script” - you define states which are associated with one or more animation clips, and then define transitions between those states based on the value of parameters.

I suggest you watch this tutorial : Unity 4.0 - Mecanim Animation Tutorial - YouTube
