//Attach this script to a GameObject with an Animator component attached.
//For this example, create parameters in the Animator and name them “Crouch” and “Jump”
//Apply these parameters to your transitions between states

//This script allows you to set a Boolean Animator parameter on and set another Boolean parameter to off if it is currently playing. Press the space key to do this.
