GameObject game object
1. Creation method
(1). Use the constructor (declaration + instantiation) to create an empty game object
void Start()
{
GameObject myGo = new GameObject("MyGameObject");
//运行unity后会在Hierarchy窗口创建一个"MyGameObject"游戏对象
}
(2). Instantiate based on existing prefab (game object) resources or existing game objects in the game scene, which is equivalent to cloning.
Operation tips: You need to create a GameObject in the Hierarchy window and drag the object to the script.
public class No3_GameObject : MonoBehaviour
{
public GameObject gb;
void Start()
{
GameObject.Instantiate(gb);
//运行unity后会在Hierarchy窗口创建一个游戏对象(clone)
}
}
(3). Use special APIs to create some basic game object types (original geometry)
void Start()
{
GameObject.CreatePrimitive(PrimitiveType.Plane);
//运行unity后会在Hierarchy窗口创建一个Plane物体
}
2. Acquisition and search of game objects
(1) To yourself (this.gameObject)
void Start()
{
Debug.Log("当前脚本挂载到的游戏物体名称是：" + gameObject.name);
//运行unity后会在控制台输出当前脚本所挂载的游戏对象名称
Debug.Log("当前游戏物体标签是："+gameObject.tag);
//运行unity后会在控制台输出当前脚本所挂载的游戏物体标签
Debug.Log("当前游戏物体层级是："+gameObject.layer);
//运行unity后会在控制台输出当前脚本所挂载的游戏物体层级
}
(2) There are references to other game objects (there are objects referenced by scripts)
public class No3_GameObject : MonoBehaviour
{
public GameObject gb;
void Start()
{
//有引用，对其他游戏物体
Debug.Log("gris游戏物体的状态是：" + gb.activeSelf);
//运行unity后会在控制台输出gb游戏物体的状态
}
}
(3) Not directly referenced, to other game objects
Attention! Search for other game objects (the game object must be active at this time)
a. Search by name
void Start()
{
GameObject mainCameraGo= GameObject.Find("Main Camera");
Debug.Log("mainCamera游戏物体的标签是：" + mainCameraGo.tag);
//运行unity后会在控制台输出MainCamera物体的标签
}
b. Search by tag
void Start()
{
GameObject mainCameraGo = GameObject.FindGameObjectWithTag("MainCamera");
Debug.Log("mainCamera游戏物体的名字是：" + mainCameraGo.name);
//运行unity后会在控制台输出MainCamera物体的名称
}
c. Search by type
Type refers to the name of the current component, here it is the class name, search by class name
Note: You need to create a script class here. The no2_EventFunction class is created here.
void Start()
{
No2_EventFunction no2_EventFunction= GameObject.FindObjectOfType<No2_EventFunction>();
Debug.Log("no2_EventFunction游戏物体的名字是：" + no2_EventFunction.name);
}
d. Most searches and acquisitions
Note:
First paragraph: Here you need to create a label and set it in the created game object Label, the Enemy label is created here.
Second paragraph: Several game objects need to be selected to add the BoxCollider component
void Start()
{
//将查找到的标签为Enemy的游戏对象放入enemyGos数组
GameObject[] enemyGos= GameObject.FindGameObjectsWithTag("Enemy");
for (int i = 0; i < enemyGos.Length; i++)
{
//遍历查找到的游戏物体名称并输出
Debug.Log("查找到的敌人游戏物体名称是："+enemyGos[i].name);
}
Debug.Log("--------------------------------------------------");
//将查找到的类型为BoxCollider的游戏组件放入colliders数组
BoxCollider[] colliders= GameObject.FindObjectsOfType<BoxCollider>();
for (int i = 0; i < colliders.Length; i++)
{
Debug.Log("查找到的敌人碰撞器名称是：" + colliders[i].name);
}
}
