I'm using the following methods to make my character jump: override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) { if onGround && !gameOver { self.character.physicsBody?.applyImpulse(CGVectorMake(0, 75)) self.onGround = false } } override func touchesEnded(touches: Set<NSObject>, withEvent event: UIEvent) { } This works fine, but I want to make the character jump a certain height based on the length of the touch until a maximum. I've tried something with frame durations but this didn't work. How can I make the character jump based on touch length until a maximum height?

I'm trying to make a button, which is when pushed - the sound is played, and when pushed again - the sound would stop. I'm using playSoundFileNamed: runAction: withKey: and removeActionForKey , but it doesn't work. The other question I have is if there is a way not only to stop the sound, but also to pause it (so that it will start from the same part it was paused, NOT from the beginning). I've seen a similar topic at stack overflow, but yet didn't find an answer on my question yet. Thank you in advance. import SpriteKit import AVFoundation var firesoundon = false private var

I'm doing a little game where the car goes around a planet. The camera is always directed to the machine at an angle of 90 degrees from the planet. I encountered a problem that the texture of the planet rotates along with the camera. If the camera does not rotate, the texture is behaving as it should. How do I fix this? Create planet from beizerPath: planetTexture = SKTexture(imageNamed: "asanoha") planet = SKShapeNode(path: beizerPath.cgPath) planet.position = CGPoint(x: 0, y: 0) planet.zPosition = 10 planet.physicsBody = SKPhysicsBody(polygonFrom: beizerPath.cgPath) planet.physicsBody?

I'm am trying to drop the SKSpriteNode with constant speed and without bouncing. Here is the code I'm using: SKSpriteNode *floor = [SKSpriteNode spriteNodeWithColor:[UIColor clearColor] size:CGSizeMake(self.size.width, 1)]; floor.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:floor.size]; floor.physicsBody.restitution = 0.0f; floor.physicsBody.dynamic = NO; floor.physicsBody.allowsRotation = NO; SKSpriteNode* block = [SKSpriteNode spriteNodeWithTexture:[SKTexture textureWithImageNamed:imageName]]; block.position = CGPointMake(160, 300); block.physicsBody = [SKPhysicsBody

I want to loop my background music with an SKAction but the music stops after one row when I switch to an other scene. Is there a way to start the loop and keep playing it over different scenes? Right now the code is placed in the init method of MyScene - is that the correct place? Maybe didFinishLaunchingWithOptions? Here is what I've tried: if (delegate.musicOn == YES && delegate.musicIsPlaying == NO) { SKAction *playMusic = [SKAction playSoundFileNamed:@"loop.wav" waitForCompletion:YES]; SKAction *loopMusic = [SKAction repeatActionForever:playMusic]; [self runAction:loopMusic]; delegate

I'm trying to make this SKScene appear in the middle of the scene at the end of the game, so that the previous scene is still visible in the background (similar to that of the ending of flappy bird). This is an image of how I want it to appear: So far this is the code I've made: in the game scene: -(void)dieFrom:(SKNode*)killingDebris { _touched = YES; if (_touched == YES) { beatLevel = YES; NSLog(@"touched"); [self runAction:[SKAction sequence:@[ [SKAction runBlock:^{ [_goodSquare removeFromParent]; }], [SKAction runBlock:^{ level2Achieved = [[NSUserDefaults standardUserDefaults]

I'd like to run a repeating SKAction but with random values on each repeat. I have read this question here that shows one way to do this. However, I want my sprite's movements to be animated, not simply changing its position. One solution I have come up with is to run a sequence of actions, with the final action calling my move method in a recursive fashion: - (void)moveTheBomber { __weak typeof(self) weakSelf = self; float randomX = // determine new "randomX" position SKAction *moveAction = [SKAction moveToX:randomX duration:0.25f]; SKAction *waitAction = [SKAction waitForDuration:0.15
