controller.Move 方法

今天遇到的这段代码很有意思，是通过给物体添加physics——charactercontroller，然后再用character.Move方法来控制物体移动，所以自带一些复杂的效果（就像实现人物character一样），例如跳跃时候和爬坡时候，完全是和人物的行为一样，贴一下官方文档：

CharacterController.Move

public CollisionFlags Move(Vector3 motion);

Description

A more complex move function taking absolute movement deltas.

Attempts to move the controller by motion, the motion will only be constrained by collisions. It will slide along colliders. CollisionFlags is the summary of collisions that occurred during the Move. This function does not apply any gravity.

using UnityEngine;
using System.Collections;

// This script moves the character controller forward
// and sideways based on the arrow keys.
// It also jumps when pressing space.
// Make sure to attach a character controller to the same game object.
// It is recommended that you make only one call to Move or SimpleMove per frame.

public class ExampleClass : MonoBehaviour
{
    CharacterController characterController;

    public float speed = 6.0f;
    public float jumpSpeed = 8.0f;
    public float gravity = 20.0f;

    private Vector3 moveDirection = Vector3.zero;

    void Start()
    {
        characterController = GetComponent<CharacterController>();
    }

    void Update()
    {
        if (characterController.isGrounded)
        {
            // We are grounded, so recalculate
            // move direction directly from axes

            moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0.0f, Input.GetAxis("Vertical"));
            moveDirection *= speed;

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

        // Apply gravity. Gravity is multiplied by deltaTime twice (once here, and once below
        // when the moveDirection is multiplied by deltaTime). This is because gravity should be applied
        // as an acceleration (ms^-2)
        moveDirection.y -= gravity * Time.deltaTime;

        // Move the controller
        characterController.Move(moveDirection * Time.deltaTime);
    }
}

（控制了小机器人的行走旋转跳跃，并判断是否在地面上，如果在空中则会下落（后续还会添加半蹲，这里存一下常来复习）
