These are some images form the character Animation Blueprint that I set up in Unreal Engine 4.

This first screen shows how animation can be blended together. This allows the character to fire a homing missile while in any animation state such as running or riding on a hover board.

Here is the animation graph of how the animation can transition to each other and which ones can play together.

Here we are gathering all the necessary booleans that allow the character to switch between animation states. Also it gathers when the player should blend animations such as firing a homing missile or an AoE attack.
