AVAudioPlayer导致我的游戏落后 [英] AVAudioPlayer causes my game to lag

问题描述

我用Xcode开发了一个简单的游戏，角色在屏幕上移动以收集硬币，同时避免被石头击中.

I've made a simple game in Xcode where the character moves around the screen to collect coins, while avoiding getting hit by rocks.

对于运动，我使用了很好的NSTimers.当我添加声音效果时，会出现问题.为此，我使用了AVAudioPlayers，它使游戏滞后了一点.我将它们注释掉，以查看它们是否引起了问题，情况似乎是这样.我在Stack Overflow和其他站点上到处都是，但是似乎找不到一个好的答案.任何帮助表示赞赏！

For the movement I use NSTimers which work fine. The problem occurs when I add sound effects. I use AVAudioPlayers for this and it makes the game lag a little bit. I commented them out to see if they caused the problem, and it seems to be the case. I've looked around here on Stack Overflow and on other sites, but I can't seem to find a good answer. Any help appreciated!

代码:

- (void)CharacterMoving {

if (CGRectIntersectsRect(Character.frame, Rock.frame)) {

    [self performSelector:@selector(GameOver) withObject:nil afterDelay:0.35];

    [Thousand play];
}

- (IBAction)Start:(id)sender {

NSString *soundEffect=[[NSBundle mainBundle]pathForResource:@"1000" ofType:@"mp3"];
Thousand=[[AVAudioPlayer alloc]initWithContentsOfURL: [NSURL fileURLWithPath:soundEffect] error:NULL];
Thousand.numberOfLoops=-0; 
}

推荐答案

我知道了.我使用系统声音服务而不是AVAudioPlayer，现在它可以正常运行.

I figured it out. I used System Sound Services instead of AVAudioPlayer, and now it works perfectly.
