Unity 船的控制

我是靠谱客的博主真实巨人，这篇文章主要介绍Unity 船的控制，现在分享给大家，希望可以做个参考。

原理

按下WS键时，给船一个前后方向上的推力
按下AD键时，给船一个围绕Y轴旋转的扭矩

扭矩 Torque

扭矩力，是使物体发生转动的力。

玩家控制

如果进入驾驶状态，则禁用玩家控制脚本，并使用父子约束将玩家固定在船上。

如果退出驾驶状态，则恢复启用玩家控制脚本，销毁父子约束组件。

配置方法

将脚本挂载在船上，并指定玩家对象

还需要限制船的刚体在X、Z轴上的旋转

效果

代码

复制代码

public class Motorboat : MonoBehaviour
{
    public GameObject player;

public float thrustForce = 50000;       //推力
    public float torque = 5000;        //扭矩

bool isOperated = false;
    private Rigidbody rigidbody;

void Start()
    {
        rigidbody = GetComponent<Rigidbody>();
    }

void Update()
    {
        if (Input.GetKeyDown(KeyCode.B) && isOperated == false)
        {
            isOperated = true;
            player.GetComponent<PlayerControl>().enabled = false;

player.AddComponent<ParentConstraint>();
            ConstraintSource constraintSource = new ConstraintSource(){
                sourceTransform = transform,
                weight = 1
            };
            player.GetComponent<ParentConstraint>().SetSources(new List<ConstraintSource>(){constraintSource});
            player.GetComponent<ParentConstraint>().SetTranslationOffset(0, new Vector3(0, 0.3f, 0));
            player.GetComponent<ParentConstraint>().constraintActive = true;
        }
        else if(Input.GetKeyDown(KeyCode.B) && isOperated == true)

            Destroy(player.GetComponent<ParentConstraint>());
        }

    }

void Move()
    {
        if(!isOperated) return;

float v = Input.GetAxis("Vertical");
        float h = Input.GetAxis("Horizontal");

rigidbody.AddForce(transform.forward * v * thrustForce);
        rigidbody.AddTorque(transform.up * h * torque);
    }
}
