Unity游戏开发笔记

// 获取自身Transform
Transform selfTF = GetComponent<Transform>(); 

// 访问属性
Vector3 position = selfTF.position;
Quaternion rotation = selfTF.rotation;
Vector3 scale = selfTF.localScale;

// 修改属性
selfTF.position = new Vector3(1, 0, 0);
selfTF.Rotate(0, 90, 0);

// 获取当前对象
GameObject selfGO = gameObject; 

// 通过名称查找子对象
Transform childTF = transform.Find("foot");

// 激活状态控制
gameObject.SetActive(false);

Apply
// 获取碰撞体
Collider2D collider = GetComponent<Collider2D>();

// 启用/禁用
collider.enabled = false;

// 触发检测 (需挂载脚本)
void OnTriggerEnter2D(Collider2D other) {
    if(other.CompareTag("Player")) {...}
}

Apply
// 获取同一物体上的组件
Rigidbody2D rb = GetComponent<Rigidbody2D>();

// 获取其他物体的组件（需先获取GameObject）
GameObject player = GameObject.Find("Player");
charactor_move_v script = player.GetComponent<charactor_move_v>();

Apply
// 在Inspector面板拖拽赋值
public Transform targetTF;

void Start() {
    Vector3 pos = targetTF.position;
}

// 获取父对象
Transform parent = transform.parent;

// 获取子对象
Transform child = transform.GetChild(0);

Apply
// 获取Rigidbody2D组件（物理模拟）
private Rigidbody2D rb;
void Start() {
    rb = GetComponent<Rigidbody2D>();
}

// 通过标签查找对象
if(other.CompareTag("FollowBox")) {...}

// 访问其他脚本属性
float power = currentPlayer.GetComponent<charactor_move_v>().kick_power;

// 修改碰撞体状态
playerCollider.enabled = false;
