测试
加载
void Update()
{
if (Input.GetMouseButtonDown(0))
{
PoolMgr.GetInstance().GetObj("Cube");
}
if (Input.GetMouseButtonDown(1))
{
PoolMgr.GetInstance().GetObj("Sphere");
}
}
回收
private void OnEnable()
{
Invoke(nameof(Push), 1f);
}
void Push()
{
PoolMgr.GetInstance().PushObj(this.gameObject.name, this.gameObject);
}
拓展
GetOrAddComponent的实现
using UnityEngine;
static public class MethodExtensionForUnity
{
/// <summary>
/// Gets or add a component. Usage example:
/// BoxCollider boxCollider = transform.GetOrAddComponent<BoxCollider>();
/// </summary>
static public T GetOrAddComponent<T>(this Component child, bool set_enable = false) where T : Component
{
T result = child.GetComponent<T>();
if (result == null)
{
result = child.gameObject.AddComponent<T>();
}
var bcomp = result as Behaviour;
if (set_enable)
{
if (bcomp != null) bcomp.enabled = true;
}
return result;
}
static public T GetOrAddComponent<T>(this GameObject go) where T : Component
{
T result = go.transform.GetComponent<T>();
if (result == null)
{
result = go.AddComponent<T>();
}
var bcomp = result as Behaviour;
if (bcomp != null) bcomp.enabled = true;
return result;
}
public static void walk(this GameObject o, System.Action<GameObject> f)
{
f(o);
int numChildren = o.transform.childCount;
for (int i = 0; i < numChildren; ++i)
{
walk(o.transform.GetChild(i).gameObject, f);
}
}
}
