例如,下面的代码会在循环的每次迭代中产生额外的内存分配: for(int i=0;i<listofobjects.Count;++i){ if(listofobjects[i].tag == "player"){ // do something with this object } } 根据对象的组件和类的类型来标识对象,以及标识不涉及字符串对象的值,这通常是一种更好的实践,但有时会陷入困境。也许...
intArray = new int[numberOfIterations]; intList = new List<int>(); intDictionary = new Dictionary<int, int>(); AddFakeValuesInArray(numberOfIterations); AddFakeValuesInList(numberOfIterations); AddFakeValuesInDictionay(numberOfIterations); } void Update() { if (Input.GetKeyDown(KeyCode.Spa...
List myListOfGameObjects =newList(); 2、Dictionary Dictionary实际上是一个哈希表类型的替代品,Dictionary代表一个键值对 例如,如果5代表Red,10代表Green,我们便在Dictionary中通过5键(Key)找到Red这个值(Value)。 因此,我们如果想要找到Red这个值(Value),只要记住5这个键(Key)即可,那么,Dictionary是怎么查找数据...
Unity supports serializing arrays and lists of objects by reference. For array andList<T>fields, the SerializeReference attribute applies to the elements of the array or list and not to the array or list object itself. You cannot assign an array or list to a field of type System.Object. In...
选择精灵图集资源,并在其 Inspector 窗口中找到 Objects For Packing 列表。此列表显示 Unity 在构建精灵图集时要打包的一组项。 To add items, select the plus (+) icon at the lower right of the list to create a new row. Drag a valid Asset onto an empty row to add it to the list, or sel...
List<string> pathList = new List<string>(); Object[] m_objects = Selection.GetFiltered(typeof(Object), SelectionMode.Unfiltered | SelectionMode.DeepAssets); foreach (var obj in m_objects) { string path = AssetDatabase.GetAssetPath(obj); if (!pathList.Contains(path)) { pathList.Add(path...
这有两个函数,一个是获取所有子对象的List集合,一个是获取所有子对象的数组集合,按需使用。 3、使用扩展方法 使用m_ParObj.GetChild()就可以调用扩展方法: 代码语言:javascript 复制 using System.Collections.Generic;using UnityEngine;publicclassSplitTest:MonoBehaviour{publicGameObject m_ParObj;privatevoidStart()...
List<ObjectPlacementRule> rules = new List<ObjectPlacementRule>() { ObjectPlacementRule.Create_AwayFromOtherObjects(1.0f), }; List<ObjectPlacementConstraint> constraints = new List<ObjectPlacementConstraint> { ObjectPlacementConstraint.Create_NearCenter(), }; Solver_PlaceObject( “MyCustomObject”, ne...
var objs = Resources.FindObjectsOfTypeAll(typeof(Transform)); GameObject selectedGo = Selection.activeGameObject; if (selectedGo == null) { Debug.Log("请先选中要查找的物体"); return; } curSelectedGo = selectedGo; var parentTranList = GetRootTranList(objs); ...
Console.WriteLine("Array collection contains {0} objects.",animalArray .Length ); animalArray[0].Feed(); ((Chicken)animalArray[1]).LayEgg(); Console.WriteLine(); //用集合的方法实现 Console.WriteLine("Create an ArrayList type collection of Animal objects and use it;"); ...
