Unity C# - 跳跃时移动角色

Question

我的角色动作很好，跳跃也很好。但是在跳跃时，他只是朝着他来的方向直线移动，在空中你不能旋转或移动他。怎么可能？

来自更新函数：

if (controller.isGrounded)
{
    moveD = new Vector3(Input.GetAxisRaw("Horizontal"), 0, Input.GetAxisRaw("Vertical"));
    moveD = transform.TransformDirection(moveD.normalized) * speed;
    moveDA = new Vector3(Input.GetAxisRaw("Horizontal"), 0, Input.GetAxisRaw("Vertical"));

    if (moveDA.magnitude > 0)
    {                 
        gameObject.transform.GetChild(0).LookAt(gameObject.transform.position + moveDA, Vector3.up);
    }

    if (Input.GetButton("Jump"))
    {
        moveD.y = jumpSpeed;
    }
}

moveD.y = moveD.y - (gravity * Time.deltaTime);
controller.Move(moveD * Time.deltaTime);

Answer 1

controller.isGrounded 仅当您最后一次调用controller.Move() 时对象的对撞机的底部接触到表面时才为真，因此在您的情况下，一旦您跳跃，您将无法移动，直到再次撞到地面。

你可以像这样分离你的移动代码和跳跃代码来解决这个问题：

moveD = new Vector3(Input.GetAxisRaw("Horizontal"), 0, Input.GetAxisRaw("Vertical"));
moveD = transform.TransformDirection(moveD.normalized) * speed;
moveDA = new Vector3(Input.GetAxisRaw("Horizontal"), 0, Input.GetAxisRaw("Vertical"));

if (moveDA.magnitude > 0) 
{ 
  gameObject.transform.GetChild(0).LookAt(gameObject.transform.position + moveDA, Vector3.up);
}

if (controller.isGrounded)
{
  if (Input.GetButton("Jump"))
  {
    moveD.y = jumpSpeed;
  }
}
moveD.y = moveD.y - (gravity * Time.deltaTime);
controller.Move(moveD * Time.deltaTime);
