我试图在游戏中创建暂停按钮。在您点击屏幕时,它将对移动器spriteNode施加一个冲动。问题是当我点击暂停按钮时仍然会施加冲动。如何在不创建冲动的情况下创建暂停按钮。
我已尝试将if语句更改为else,如果然后将最后一个脉冲部分作为else部分,但这不会起作用。
touchBegan方法:
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInNode:self];
SKNode *node = [self nodeAtPoint:location];
//if fire button touched, bring the rain
if ([node.name isEqualToString:@"repeat"]) {
SKTransition *reveal = [SKTransition fadeWithDuration:2.0 ];
MyScene *newScene = [[MyScene alloc] initWithSize: CGSizeMake(self.size.width,self.size.height)];
// Optionally, insert code to configure the new scene.
[self.scene.view presentScene: newScene transition: reveal];
}
if ([node.name isEqualToString:@"home"]) {
SKTransition *reveal = [SKTransition fadeWithDuration:2.0 ];
Menu *newScene = [[Menu alloc] initWithSize: CGSizeMake(self.size.width,self.size.height)];
// Optionally, insert code to configure the new scene.
[self.scene.view presentScene: newScene transition: reveal];
}
if ([node.name isEqualToString:@"pause"]) {
[self pausedMenu];
}
if ([node.name isEqualToString:@"start"]) {
[self startMenu];
}
showpipes = showpipes + 1;
if (showpipes == 1) {
self.physicsWorld.gravity = CGVectorMake( 0.0, -5.0 );
SKAction* spawn = [SKAction performSelector:@selector(spawnPipes) onTarget:self];
SKAction* delay = [SKAction waitForDuration:2.0];
SKAction* spawnThenDelay = [SKAction sequence:@[spawn, delay]];
SKAction* spawnThenDelayForever = [SKAction repeatActionForever:spawnThenDelay];
[self runAction:spawnThenDelayForever];
}
started = 1;
if (noImpulse == 1) {
if (started == 1) {
mover.physicsBody.restitution = 0.0;
mover.physicsBody.velocity = CGVectorMake(0, 0);
[mover.physicsBody applyImpulse:CGVectorMake(0, 15)];
}
}
}
PAUSEDMENU方法:
-(void)pausedMenu
{
self.scene.paused = YES;
mover.scene.paused = YES;
[repeatButton removeFromParent];
[homeButton removeFromParent];
[menuBackground removeFromParent];
menuBackground = [SKSpriteNode spriteNodeWithColor:[SKColor colorWithWhite:0.0 alpha:0.3] size:CGSizeMake(self.frame.size.width*2, self.frame.size.height*2)];
[self addChild:menuBackground];
[pauseButton removeFromParent];
startButton = [SKSpriteNode spriteNodeWithImageNamed:@"staart"];
startButton.name = @"start";
startButton.position = CGPointMake(20, self.size.height-20);
startButton.size = CGSizeMake(40, 40);
[self addChild:startButton];
repeatButton = [SKSpriteNode spriteNodeWithImageNamed:@"repeat"];
repeatButton.name = @"repeat";
repeatButton.position = CGPointMake(self.size.width/2+30, self.size.height/2);
repeatButton.size = CGSizeMake(repeatButton.size.width/2, repeatButton.size.height/2);
[self addChild:repeatButton];
homeButton = [SKSpriteNode spriteNodeWithImageNamed:@"home"];
homeButton.name = @"home";
homeButton.position = CGPointMake(self.size.width/2-30, self.size.height/2);
homeButton.size = CGSizeMake(homeButton.size.width/2, homeButton.size.height/2);
[self addChild:homeButton];
}

退房 https://developer.apple.com/library/ios/documentation/SpriteKit/Reference/SKView/Reference/Reference.html#//apple_ref/occ/instp/SKView/paused 如果您暂停包含游戏的SKView,则所有状态都将被暂停,您可以在暂停菜单被取消后恢复它。您必须在另一个SKView中显示暂停菜单,然后是您的游戏所包含的暂停菜单。
