A.
要處理不同body(機體),想了好久,才想出要用介面來當成溝通不同機體的橋樑,滿妙的窩,當按一下按鈕就能更換body和同時更換子彈,bullet1是繼承bullet而來,body1是繼承了body而來,並改寫部份程序.
只要我想在增加body2,bullet2,繼承body,bullet,改寫部份程序,又是另一個機體和武器,並在介面加一些溝通body程式既可
介面是放在bodylist class
下面是呼叫不同body程序,new bodylist(new body(500,10,4))是產生一個新機體
void Frame::change_body(int i)
{
switch (i)
{
case 0 : this->thisbody=new bodylist(new body(500,10,4));thread->set_bodylist(thisbody);break ;
case 1 : this->thisbody=new bodylist(new body1(500,10,4));thread->set_bodylist(thisbody);break ;
}
}
目前換機體只換子彈大小,後續會改寫子彈路徑,威力和機體形狀
B.多載建構子宣告,注意body* b和body1* b是不同body,來達成多載
bodylist(body* b,QWidget *parent=0); //多載,利用多載來設定不同機體,注意*parent=0和*parent不同
bodylist(body1* b1,QWidget *parent=0);//多載,利用多載來設定不同機體
C.介面
////增加body,此處介面要記得加上去
#include "bodylist.h"
bodylist::bodylist(body* b ,QWidget *parent)
{
body_0=b; //body初始化
body_id=0; //id
}
bodylist::bodylist(body1* b1 ,QWidget *parent)
{
body_1=b1; //body初始化
body_id=1; //id
}
void bodylist::set_x(int i)
{
switch(body_id)
{
case 0:this->body_0->set_x(i);break;
case 1:this->body_1->set_x(i);break;
}
}
void bodylist::set_y(int i)
{
switch(body_id)
{
case 0:this->body_0->set_y(i);break;
case 1:this->body_1->set_y(i);break;
}
}
