我正在制作一个CCSprite
(它应该代表一个炸弹),就像双击一样。
- (void)handleDoubleTap:(UITapGestureRecognizer *)doubletapRecognizer
{
[self placeBomb];
}
-(void)placeBomb
{
NSLog(@"Bomb placed");
_circle = [[CCSprite alloc]initWithFile:@"Circle.png"];
CGPoint circle0position = ccp(_cat.position.x , _cat.position.y);
CGPoint c0TileCoordt = [self tileCoordForPosition:circle0position];
CGPoint c0TileCoord = [self positionForTileCoord:c0TileCoordt];//Supereffective way to get rid of decimals
_circle.position = c0TileCoord;
[self addChild:_circle];
id fade = [CCScaleTo actionWithDuration:3.5 scale:0];
[_circle runAction:fade];
[self performSelector:@selector(explosion) withObject:nil afterDelay:3];
}
然后我运行-(void)explosion
- 惊讶 - 使其爆炸,然后再次调用checkForDamage方法,该方法在爆炸的生命周期内测试爆炸区域内的碰撞。
问题是我不想限制炸弹(精灵)的数量,但是当我现在放置两颗炸弹时,第一颗炸弹的爆炸发生在第二颗炸弹的位置,我显然可以不要责怪,因为这就是我要求它做的事情。爆炸是基于_circle.position
爆炸块大约有三百行,所以我不打扰你在(Heres pastebin link)张贴它,但作为一个例子,我将发布checkForDamage。
-(void)checkForDamage //Gets called with CCTime on explosion
{
bool playerHit = NO;
CGPoint bombPos = [self tileCoordForPosition:_circle.position];
for (int i = 0; i <= explosionLenght; i++)
{
CGPoint playerPosF = [self tileCoordForPosition:_cat.position];
int bombX = (bombPos.x + i);
int bombY = (bombPos.y + i);
int bombNegX = (bombPos.x - i);
int bombNegY = (bombPos.y - i);
CGPoint centre = bombPos;
CGPoint top = ccp(centre.x, bombY);
CGPoint left = ccp(bombNegX, centre.y);
CGPoint bottom = ccp(centre.x, bombNegY);
CGPoint right = ccp(bombX, centre.y);
if (CGPointEqualToPoint(top, playerPosF) ||
CGPointEqualToPoint(left, playerPosF) ||
CGPointEqualToPoint(bottom, playerPosF) ||
CGPointEqualToPoint(right, playerPosF))
{
playerHit = YES;
NSLog(@"Player hit, BOOL:%i",playerHit);
[self unschedule:@selector(checkForDamage)];
break;
}
}
[self performSelector:@selector(stopCheckDamage) withObject:nil afterDelay:2];
}
如何创建_circle
炸弹的多个实例,以便我可以同时进行多次爆炸并检查是否有损坏。我尝试使用for
循环并使用标记创建精灵,但我不知道如何通过标记全局访问和执行sprite上的内容。我想为每次爆炸制作一个不同的精灵,比如
if (explosion1exists) {explosion with circle1}, if (expl1 + expl2 exists) {expl with circle3}
但是,由于我最多会放置20到30枚炸弹,这种情况非常无效,我认为必须有更好的方法。任何方法有效地做到这一点?
