如今槍彈碰撞配角 並沒有產生工作 須要槍彈和配角的碰撞檢測
//修正Player類 添加碰撞檢測
// // 斷定碰撞(配角與敵機槍彈)
public boolean isCollsionWith(Bullet bullet) {
// 能否處於無敵時光
if (isCollision == false) {
int x2 = bullet.bulletX;

} else if (x <= x2 && x + bmpPlayer.getWidth() <= x2) {
return false;
} else if (y >= y2 && y >= y2 + h2) {
return false;
} else if (y <= y2 && y + bmpPlayer.getHeight() <= y2) {
return false;
}
// 碰撞即進入無敵狀況
isCollision = true;
return true;
// 處於無敵狀況，疏忽碰撞
} else {
return false;
}
}
在主界面 MySrufaceView 的邏輯函數中添加 配角和敵機槍彈的碰撞
//處置敵機槍彈與配角碰撞
for (int i = 0; i < vcBullet.size(); i++) {
if (player.isCollsionWith(vcBullet.elementAt(i))) {
//產生碰撞，配角血量-1
player.setPlayerHp(player.getPlayerHp() - 1);
//當配角血量小於0，剖斷游戲掉敗
if (player.getPlayerHp() <= -1) {
gameState = GAME_LOST;
}
}
}
固然 配角的槍彈碰撞了敵機 也須要停止碰撞檢測 修正 敵機類 Enemy
//斷定碰撞(敵機與配角槍彈碰撞)
public boolean isCollsionWith(Bullet bullet) {
int x2 = bullet.bulletX;
int y2 = bullet.bulletY;
int w2 = bullet.bmpBullet.getWidth();
int h2 = bullet.bmpBullet.getHeight();
if (x >= x2 && x >= x2 + w2) {
return false;
} else if (x <= x2 && x + frameW <= x2) {
return false;
} else if (y >= y2 && y >= y2 + h2) {
return false;
} else if (y <= y2 && y + frameH <= y2) {
return false;
}
//產生碰撞，讓其逝世亡
isDead = true;
return true;
}
在主視圖中添加邏輯 配角槍彈和敵機碰撞的邏輯
//處置配角槍彈與敵機碰撞
for (int i = 0; i < vcBulletPlayer.size(); i++) {
//掏出配角槍彈容器的每一個元素
Bullet blPlayer = vcBulletPlayer.elementAt(i);
for (int j = 0; j < vcEnemy.size(); j++) {
//添加爆炸後果 待完成
}
}
