objective-c – Sprite Kit – iOS 7.1更新后由于比例而导致的对象冲突

概述没有问题,但在iOS 7.1更新后,对象正在碰撞2管的差距.之前有人说,可能是因为’yScale’,但我找不到解决方案. 一些代码; Pipe *pipe = [[Pipe alloc] initWithImageNamed:pipeImageName]; [pipe setCenterRect:CGRectMake(26.0/kPipeWidth, 26.0/kPipeWidth, 4.0/ 没有问题,但在iOS 7.1更新后,对象正在碰撞2管的差距.之前有人说,可能是因为’yScale’,但我找不到解决方案.

一些代码;

Pipe *pipe = [[Pipe alloc] initWithImagenamed:pipeImagename];  [pipe setCenterRect:CGRectMake(26.0/kPipeWIDth,26.0/kPipeWIDth,4.0/kPipeWIDth,4.0/kPipeWIDth)];  [pipe setYScale:height/pipe.size.height];  [pipe setposition:CGPointMake(320+(pipe.size.wIDth/2),abs(pipeYOffset + (pipe.size.height/2)))];  pipe.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:pipe.size];  [pipe.physicsBody setAffectedByGravity:NO];  [pipe.physicsBody setDynamic:NO];

任何帮助将不胜感激.谢谢！

解决方法

Pipe *pipe = [[Pipe alloc] initWithImagenamed:pipeImagename];  [pipe setCenterRect:CGRectMake(26.0/kPipeWIDth,4.0/kPipeWIDth)];//set the physicsBody before X/Yscale  pipe.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:pipe.size];  [pipe setYScale:height/pipe.size.height];  [pipe setposition:CGPointMake(320+(pipe.size.wIDth/2),abs(pipeYOffset + (pipe.size.height/2)))];  [pipe.physicsBody setAffectedByGravity:NO];  [pipe.physicsBody setDynamic:NO];

这可能对你有所帮助.我认为这是ios7.1中的一个错误.
