Unity常用游戏基础功能

生成新的Object

public GameObject objectPrefab;

GameObject newObject = Instantiate(objectPrefab) as GameObject;			//1
GameObject newObject = (GameObject)Instantiate(objectPrefab);			//2
Transform newObject = Instantiate(myPrefab) as Transform;				//3
Transform newObject = (Instantiate(myPrefab) as GameObject).transform;	//4
Transform newObject = (Instantiate(myPrefab) as GameObject).GetComponent<Transform>();	//5

较建议使用的ObjectPool

public GameObject objectPrefab;
public Transform inUseParent;
public List<Transform> objectInPool;
public List<Transform> objectInUse;

public Transform GetNewObject()
{
    
    
	Transform newObj = null;
	if(objectInPool.Count > 0)
	{
    
    
		newObj = objectInPool[0];
		SetObjStatus(newObj, true);
	}
	else
	{
    
    
		newObj = (Instantiate(objectPrefab) as GameObject).transform;
        objectTransform.SetParent(inUseParent, false);
        SetObjStatus(newObj, true);
	}
	return newObj;
}

public void SetObjStatus(Transform obj, bool SetToInUse)
{
    
    
	if(obj != null)
	{
    
    
		obj.gameObject.SetActive(SetToInUse);
		if(SetToInUse)
		{
    
    
			if(objectInPool.Contains(obj))
			{
    
    
				objectInPool.Remove(obj);
			}
			if(!objectInUse.Contains(obj))
			{
    
    
				objectInUse.Add(obj);
			}
		}
		else
		{
    
    
			if(!objectInPool.Contains(obj))
			{
    
    
				objectInPool.Add(obj);
			}
			if(objectInUse.Contains(obj))
			{
    
    
				objectInUse.Remove(obj);
			}
		}
	}
}

Collider

1. 首先，所有有关的GameObject上面必须有Collider，IsTrigger不勾选。
2. 触发Collider的GameObject任何之一必须有RigiBody，其UseGravity必须勾选，IsKinematic不能勾选。
3. 如果不想其受重力影响请修改其他参数。

private void OnCollisionEnter(Collision col)
{
    
    
	Debug.Log("Col Enter");
	
}
