[英]process functions and variables from derived class of abstract
How do i circumvent questioning from any derived class and writing the code twice? 我如何规避来自任何派生类的询问并编写两次代码?
I have tried the following: 我尝试了以下方法:
Type t = GetType(obj);
(obj as t).health
By doing this, Visual Sudio saysme health is not member of... blah
通过这样做,Visual Sudio说我的health is not member of... blah
Here's my code: 这是我的代码:
// gameobjects-class
abstract gameobject
{
Vector2 Position
void update()
etc...
class meteor : gameobject
{
float rotation
etc...
class player : gameobject
{
int health, attackpower
etc...
class enemy: gameobject
{
int health, attackpower
etc...
External class accessing data from GameObject
外部类从GameObject
访问数据
class anyclass
{
void checkhealth(gameobject obj) // QUESTION:
{
if (obj as player).health = 0 //
kill(obj) //
if (obj as enemy).health = 0 //
kill(obj) //
Any suggestion? 有什么建议吗? Thanks! 谢谢!
You can create an interface for living objects and then pass that to the method 您可以为活动对象创建接口,然后将其传递给方法
interface ILivingGameObject
{
int Health {get;set;}
}
class Player : GameObject, ILivingGameObject
{
}
void CheckHealth(ILivingGameObject obj)
{
if(obj.Health == 0)
kill(obj);
}
You can read more on Interfaces here 您可以在此处阅读有关接口的更多信息
Alternatively you can create a LivingObject
class that both player and enemy inherit from and pass this to the method 或者,您可以创建一个既包含玩家又包含敌人的LivingObject
类,并将其传递给方法
class LivingObject : GameObject
{
int Health {get;set;}
}
class Player : LivingObject
{
}
void CheckHealth(LivingObject obj)
{
}
