我非常沮喪,我知道這是因爲我不知道我在做什麼與cocos2d。我正在關注cocos2d上的Ray Wenderlich教程,我正試圖將它們放在一起。當輕擊屏幕時,一個子彈朝水龍頭方向發射。我使用發射了多少子彈?
- (void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
CGPoint touchLocation = [self convertTouchToNodeSpace:touch];
[self.officer shootToward:touchLocation];
[self.officer shootNow];
}
- (void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
CGPoint touchLocation = [self convertTouchToNodeSpace:touch];
[self.officer shootToward:touchLocation];
[self.officer shootNow];
}
它調用了我的軍官階層這些方法
- (void)shootNow {
// 1
CGFloat angle = ccpToAngle(_shootVector);
_gun.rotation = (-1 * CC_RADIANS_TO_DEGREES(angle)) + 90;
// 2
CGSize winSize = [[CCDirector sharedDirector] winSize];
float mapMax = MAX(winSize.width, winSize.height);
CGPoint actualVector = ccpMult(_shootVector, mapMax);
// 3
float POINTS_PER_SECOND = 300;
float duration = mapMax/POINTS_PER_SECOND;
// 5
for(id item in self.children) {
NSString *bulletName = [NSString stringWithFormat:@"bullet.png"];
CCSprite * bullet = [CCSprite spriteWithSpriteFrameName:bulletName];
//bullet.tag = _type;
bullet.position = ccpAdd(self.position, ccpMult(_shootVector, _gun.contentSize.height));
CCMoveBy * move = [CCMoveBy actionWithDuration:duration position:actualVector];
CCCallBlockN * call = [CCCallBlockN actionWithBlock:^(CCNode *node) {
[node removeFromParentAndCleanup:YES];
}];
[bullet runAction:[CCSequence actions:move, call, nil]];
[self.batchNode addChild:bullet];
//[self addChild:bullet];
[_shotsFired addObject:bullet];
}
}
所以我想這將是一個簡單的for循環經過第5步x量的時間,然後調用重載方法。那沒有用。所以我試圖計算屏幕上的觸摸,我想如果我得到了x的水龍頭然後調用重載方法(這還沒有寫入)?與此相關的問題是每次按下屏幕的不同區域時,計數都從一個開始。有些人請幫助我完成這一週拉長頭髮的漫長過程嗎?我如何計算我開槍的次數?
哇多麼容易!我覺得在智能方面沒有那麼多! –
