Transform child = transform.find("children1");transform.position =newVector3(0,1,0)transfrom.gameObject.name ="1234"; 在C#那边几乎没有性能问题,但是在lua这边因为字符串传递的消耗,以及lua这边会把Vector3当成table或者userdata处理,很容易就会因为开发者的疏忽从而导致一些意想不到的瓶颈问题。

Vector3等值类型的消耗,前面已经有所提及。 而数组则更甚,因为lua中的数组只能以table表示,这和c#下完全是两码事,没有直接的对应关系,因此从c#的数组转换为luatable只能逐个复制,如果涉及object/string等,更是要逐个转换。 5.频繁调用的函数,参数的数量要控制 ...
static void SetPos(GameObject obj, float x, float y, float z){obj.transform.position = new Vector3(x, y, z); } } 然后在lua中LuaUtil.SetPos(obj, pos.x, pos.y, pos.z),这样的性能会好非常多,因为省掉了transform的频繁返回,而且还避免了transform经常临时返回引起lua的gc。
