我有一个带有菜单场景、游戏场景和游戏结束场景的游戏。当我在其中一个上时，有办法不在后台运行其他人。例如，在我的游戏场景中，当您与某物接触时，它会切换到游戏结束场景。当我在菜单场景上时，播放场景运行，当它接触时，它切换到游戏结束场景。
所以我的问题是：我可以让场景不会在后台运行吗？或者有一种方法可以延迟它直到我按下菜单上的播放按钮？
这是第一个场景的代码：
#import "WEMenuScene.h"
#import "WEMyScene.h"
@implementation WEMenuScene
-(id)initWithSize:(CGSize)size {
if (self = [super initWithSize:size]) {
/* Setup your scene here */
self.scaleMode = SKSceneScaleModeAspectFill;
SKSpriteNode* background = [SKSpriteNode spriteNodeWithImageNamed:@"landscape"];
background.position = CGPointMake(CGRectGetMidX(self.frame),CGRectGetMidY(self.frame));
background.zPosition = 1000;
[self addChild:background];
[self addChild:[self playButton]];
}
return self;
}
-(SKSpriteNode *) playButton {
SKSpriteNode* play = [SKSpriteNode spriteNodeWithImageNamed:@"Play"];
play.position = CGPointMake(CGRectGetMidX(self.frame), 300);
play.zPosition = 1200;
play.name = @"playButton";
return play;
}
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInNode:self];
SKNode* node = [self nodeAtPoint:location];
if ([node.name isEqualToString:@"playButton"]) {
SKScene* playScene = [[WEMyScene alloc] initWithSize:self.size];
SKTransition* transitionPlay = [SKTransition doorsOpenVerticalWithDuration:0.5];
[self.view presentScene:playScene transition:transitionPlay];
}
}
@end
这是第二个场景的代码：
