c# - 我怎样才能在触摸 "Kinematic"Rigidbody2D上移动？

Question

所以有我的角色的 Rigidbody2D 附件的代码，但当设置为运动学(仅适用于动态)时他不会移动，但我想要运动学，因为他与动态对象发生碰撞，我不希望他移动只需向左和向右触摸即可。

UI:我很初学者，我只想制作我的第一个 Android 游戏，也很抱歉我的英语。 :D

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Movement : MonoBehaviour
{
    //variables
    public float moveSpeed = 300;
    public GameObject character;

    private Rigidbody2D characterBody;
    private float ScreenWidth;


    // Use this for initialization
    void Start()
    {
        ScreenWidth = Screen.width;
        characterBody = character.GetComponent<Rigidbody2D>();
    }

    // Update is called once per frame
    void Update()
    {
        int i = 0;
        //loop over every touch found
        while (i < Input.touchCount)
        {
            if (Input.GetTouch(i).position.x > ScreenWidth / 2)
            {
                //move right
                RunCharacter(1.0f);
            }
            if (Input.GetTouch(i).position.x < ScreenWidth / 2)
            {
                //move left
                RunCharacter(-1.0f);
            }
            ++i;
        }
    }
    void FixedUpdate()
    {
#if UNITY_EDITOR
        RunCharacter(Input.GetAxis("Horizontal"));
#endif
    }

    private void RunCharacter(float horizontalInput)
    {
        //move player
        characterBody.AddForce(new Vector2(horizontalInput * moveSpeed * Time.deltaTime, 0));

    }
}

来自Unity docs ,

If isKinematic is enabled, Forces, collisions or joints will not affect the rigidbody anymore.

所以不用施加力，只需改变它的位置即可。像这样的事情:

private void RunCharacter(float horizontalInput)
{
    //move player
    characterBody.transform.position += new Vector2(horizontalInput * moveSpeed * Time.deltaTime, 0);

}
