\"Move<\/figure>\n\n\n\n

In my previous post I made a short post about how to make a character move with the Character Controller component<\/a> in the end. We can continue on this path and add some more to our script to make our character use a walking animation too. This is a tutorial on how to move character with animation through script. Thankfully there are already some great assets out there and one I found useful was the animation package called Basic Motions<\/a> made by Kevin Iglesias.<\/p>\n\n\n\n

If you download Basic Motion there you can drag the Prefab BasicMotionsDummy into your scene. <\/p>\n\n\n\n

Then what I did was creating a new Animation controller<\/strong> for your character<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Add your new Animation Controller to your Controller for your BasicMotionsDummy character. Then edit the new controller and expand the BasicMotions@Walk<\/strong> animation from the Basic Motions\/Animations\/Movement folder and pick the one called “BasicMotions@Walk01 – Forwards” into your controller. Also add the idle animation “BasicMotions@Idle01<\/strong>“. You can rename your animations to something more simple like Walk and Idle. Then add transition and add a transition from Any State to your Walk one, and do the same for Idle. Then go to the Parameters tab and add two new parameters, TryWalk and StopWalk. Click on the white arrow from Any State to your Walk animation and plus click to add a Condition, select “TryWalk”. Do the same for idle, click on the white arrow from Any State to your Idle and add “StopWalk”.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Now select so that you use your Animator Controller as Controller in your BasicMotionsDummy character.<\/p>\n\n\n\n

Since we now have triggers which will play the animations we can trigger them through our scripts with simply animator.Trigger(“TryWalk”) or animator.Trigger(“StopWalk”) for example. Let’s take a look. Add a script called MainCharacter to your character controller 3D object with the following code:<\/p>\n\n\n

\nusing UnityEngine;\nusing UnityEngine.UI;\n\npublic class MainCharacter : MonoBehaviour\n{\n    private CharacterController controller;\n    private Vector3 playerVelocity;\n    private Animator animator;\n    private float speed = 2.0f;\n    private float gravityValue = -9.81f;\n\n    private Vector3 prevPos;\n    private bool isWalking;\n    private bool walkingTriggered;\n    private bool stopWalkingTriggered;\n    void Start()\n    {\n        controller = GetComponent<CharacterController>();\n        animator = GetComponent<Animator>();\n    }\n\n    void triggerWalk()\n    {\n        animator.SetTrigger("TryWalk");\n        walkingTriggered = true;\n        stopWalkingTriggered = false;\n    }\n    void triggerStopWalk()\n    {\n        animator.SetTrigger("StopWalk");\n        stopWalkingTriggered = true;\n        walkingTriggered = false;\n    }\n\n    \/\/ Update is called once per frame\n    void Update()\n    {\n        if (isWalking)\n        {\n            if(!walkingTriggered)\n            {\n                triggerWalk();\n            }\n        } else {\n            if(!stopWalkingTriggered)\n            {\n                triggerStopWalk();\n            }\n        }\n\n        isWalking = (prevPos.x != transform.position.x) || (prevPos.z != transform.position.z);\n        \n        prevPos = transform.position;\n        Vector3 move = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));\n        controller.Move(move * Time.deltaTime * speed);\n\n        if (move != Vector3.zero)\n        {\n            gameObject.transform.forward = move;\n        }\n\n        playerVelocity.y += gravityValue * Time.deltaTime;\n        controller.Move(playerVelocity * Time.deltaTime);\n    }\n} \n\n<\/pre><\/div>\n\n\n
I’ve also added the following components to my character (BasicMotionsDummy):<\/p>\n\n\n\n
