Unity Character Controller动画问题

Question

我刚开始团结一致时就冒险了。

当我按“ W”键且没有任何按键按下Stop时，我需要使角色打开动画步，并为不移动而设置空闲动画（对不起，我的英语不是我的母语）那么当我按下空格键时，char应该跳动并使用跳跃动画，而我的char确实在移动并跳动，但是即使我不按任何键也只重复一个动画。

此外，我想像《刺客信条》那样进行爬升，壁架爬升，角色从边缘掉落等。我想在按键上播放动画。I just start to figure it out using transition but still luck of results

我不确定应该更改什么，需要帮助。

using UnityEngine;
using System.Collections;

public class PlayerController2 : MonoBehaviour

    public float walkSpeed = 20;
    public float runSpeed = 40;
    public float gravity = -80;
    public float jumpHeight = 15;
    [Range(0, 1)]
    public float airControlPercent;

    public float turnSmoothTime = 0.2f;
    float turnSmoothVelocity;

    public float speedSmoothTime = 0.1f;
    float speedSmoothVelocity;
    float currentSpeed;
    float velocityY;

    Animator animator;
    Transform cameraT;
    CharacterController controller;

    void Start()
    {
        animator = GetComponent<Animator>();
        cameraT = Camera.main.transform;
        controller = GetComponent<CharacterController>();
    }

    void Update()
    {
        // input
        Vector2 input = new Vector2(Input.GetAxisRaw("Horizontal"), Input.GetAxisRaw("Vertical"));
        Vector2 inputDir = input.normalized;
        bool running = Input.GetKey(KeyCode.LeftShift);

        Move(inputDir, running);

        if (Input.GetKeyDown(KeyCode.Space))
        {
            Jump();
        }
        // animator
        float animationSpeedPercent = ((running) ? currentSpeed / runSpeed : currentSpeed / walkSpeed * .5f);
        animator.SetFloat("speedPercent", animationSpeedPercent, speedSmoothTime, Time.deltaTime);

    }

    void Move(Vector2 inputDir, bool running)
    {
        if (inputDir != Vector2.zero)
        {
            float targetRotation = Mathf.Atan2(inputDir.x, inputDir.y) * Mathf.Rad2Deg + cameraT.eulerAngles.y;
            transform.eulerAngles = Vector3.up * Mathf.SmoothDampAngle(transform.eulerAngles.y, targetRotation, ref turnSmoothVelocity, GetModifiedSmoothTime(turnSmoothTime));
        }

        float targetSpeed = ((running) ? runSpeed : walkSpeed) * inputDir.magnitude;
        currentSpeed = Mathf.SmoothDamp(currentSpeed, targetSpeed, ref speedSmoothVelocity, GetModifiedSmoothTime(speedSmoothTime));

        velocityY += Time.deltaTime * gravity;
        Vector3 velocity = transform.forward * currentSpeed + Vector3.up * velocityY;

        controller.Move(velocity * Time.deltaTime);
        currentSpeed = new Vector2(controller.velocity.x, controller.velocity.z).magnitude;

        if (controller.isGrounded)
        {
            velocityY = 0;
        }

    }

    void Jump()
    {
        if (controller.isGrounded)
        {
            float jumpVelocity = Mathf.Sqrt(-2 * gravity * jumpHeight);
            velocityY = jumpVelocity;
        }
    }

    float GetModifiedSmoothTime(float smoothTime)
    {
        if (controller.isGrounded)
        {
            return smoothTime;
        }

        if (airControlPercent == 0)
        {
            return float.MaxValue;
        }
        return smoothTime / airControlPercent;
    }
}
