Unity编辑器选择器工具类Selection常用函数示例详解

// 获取当前活动的上下文对象
Object activeContext = Selection.activeContext;

// 设置当前活动的上下文对象
Selection.activeContext = activeContext;

// 获取当前活动的游戏对象
GameObject activeGameObject = Selection.activeGameObject;
// 设置当前活动的游戏对象
Selection.activeGameObject = activeGameObject;

// 获取当前活动的实例ID
int activeInstanceID = Selection.activeInstanceID;

// 设置当前活动的实例ID
Selection.activeInstanceID = activeInstanceID;

// 获取当前活动的对象
Object activeObject = Selection.activeObject;

// 设置当前活动的对象
Selection.activeObject = activeObject;

// 获取当前活动的变换组件
Transform activeTransform = Selection.activeTransform;

// 设置当前活动的变换组件
Selection.activeTransform = activeTransform;

// 获取当前选择的资源的GUID数组
string[] assetGUIDs = Selection.assetGUIDs;

// 遍历打印每个资源的GUID
foreach (string guid in assetGUIDs)
{
    Debug.Log("Asset GUID: " + guid);
}

// 获取当前选择的对象数量
int count = Selection.count;

// 打印当前选择的对象数量
Debug.Log("Selection count: " + count);

// 获取当前选择的游戏对象数组
GameObject[] gameObjects = Selection.gameObjects;

foreach (GameObject obj in gameObjects)
{
    Debug.Log("Game Object Name: " + obj.name);
}

// 获取当前选择的实例ID数组
int[] instanceIDs = Selection.instanceIDs;
// 遍历打印每个实例ID
foreach (int instanceID in instanceIDs)
{
    Debug.Log("Instance ID: " + instanceID);
}

// 获取当前选择的对象数组
Object[] objects = Selection.objects;

// 遍历打印每个对象的名称
foreach (Object obj in objects)
{
    Debug.Log("Object Name: " + obj.name);
}

// 获取当前选择的变换组件数组
Transform[] transforms = Selection.transforms;

// 遍历打印每个变换组件的位置
foreach (Transform transform in transforms)
{
    Debug.Log("Transform Position: " + transform.position);
}

// 检查游戏对象是否在当前选择中
bool contains = Selection.Contains(gameObject);

// 打印结果
Debug.Log("Contains: " + contains);

// 获取当前选择的所有MeshRenderer组件
MeshRenderer[] meshRenderers = Selection.GetFiltered<MeshRenderer>(SelectionMode.Deep);
// 遍历打印每个MeshRenderer的材质数量
foreach (MeshRenderer renderer in meshRenderers)
{
    Debug.Log("Material Count: " + renderer.sharedMaterials.Length);
}

// 获取当前选择的所有变换组件
Transform[] transforms = Selection.GetTransforms(SelectionMode.TopLevel | SelectionMode.OnlyUserModifiable);
// 遍历打印每个变换组件的名称
foreach (Transform transform in transforms)
{
    Debug.Log("Transform Name: " + transform.name);
}

// 设置当前活动的对象和上下文
Selection.SetActiveObjectWithContext(gameObject, context);
// 打印当前活动的对象和上下文
Debug.Log("Active Object: " + Selection.activeObject);
Debug.Log("Active Context: " + Selection.activeContext);
