程式碼

blog不能顯示尖括號,只好寫個sed小程式來取代,要放上程式就要先轉換

目前加上enemy的畫面,enmy是利用qrand()造成亂動畫面,產生一隻enemy就加入QVector,enemy.cpp放著座標

用這個public來設enemy座標
void enemy::set_enemy_x(int x1)//一次只能一個
{
this->enemy_xx=x1;
}
用這個public來取得enemy座標
int enemy::getx()
{
return this->enemy_xx;
}

這個是滿有用的技巧,是當初在玩java時看人用的,套用在C++也通用.

stage.cpp這個是放障礙物的class
bullet.cpp這個是放子彈座標的class
enemy.cpp這個是放敵人的class
whread.cpp這是執行續class
frame.cpp視窗體class
