This first example script connects user keyboard input with changes in Animator animationState. There is no logic to move the gameObject, or change values of the Transform Position vector values: x, y, z.
Simple Script to connect key-input to Animator Parameter: "HeroState".
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerController : MonoBehaviour
{
//create custom data-type
public enum HeroState { idle = 0, walk = 1, jump = 2} //custom data-type
public HeroState currentHeroState; //variable to keep track of current animation state
private bool facingRight = true; // initialize when declare (first way), false by default
private Animator animator; //obj-reference variable to access the animator component on this gameObject
//inspector is the second way to initialize a value
// Start is called before the first frame update
private void Start()
{
facingRight = true; //final way to initialize, overrides all prior settings
animator = GetComponent<Animator>(); //<T> //call a method - make connection to component on gameObject in Unity scene
animator.SetInteger( "HeroState", (int) HeroState.idle );
}
//Fixed update used for physics, to give smooth motion, called at consistent time increments
void FixedUpdate()
{
float inputX = Input.GetAxis("Horizontal"); // key input: -1, 0, 1
bool isWalking = Mathf.Abs(inputX) > 0;
//check for spacebar or w, up keys to indicate vertical jump
bool jumpPressed = Input.GetButtonDown("Jump") || Input.GetAxis("Vertical") > 0;
if (isWalking)
{
animator.SetInteger("HeroState", (int)HeroState.walk);
}
else
{
animator.SetInteger("HeroState", (int)HeroState.idle);
}
if (jumpPressed)

animator.SetInteger("HeroState", (int)HeroState.jump);
