skaction

I have the following code to move an SKSpriteNode . let moveDown = SKAction.moveBy(CGVectorMake(0, -120), duration: 1) let moveUp = SKAction.moveBy(CGVectorMake(0, +120), duration: 1) let moveSequence = SKAction.sequence([moveDown, moveUp]) square.runAction(SKAction.repeatActionForever(moveSequence)) This moves the SKSpriteNode up and down forever. Is there a way that I could pause this SKAction ? So that the SKSpriteNode will freeze in its current position, and then later when I decide, continue its movement? I only want to pause the movement of this SKSpriteNode . I do not want to pause the

I have a subclass of SKSpriteNode (monsterNode). It automatically runs around the screen using vectors to follow the player. I am currently using the following action to make it run around: SKAction *actionMove = [SKAction moveTo:actualDistance duration:time]; [self runAction:actionMove completion:^ { _currentState = SVGMonsterStateIdle; }]; I am wondering if its possible to make it so the monsterNode actually STOPS running the action if it hits the boundary of the iOS device screen. I currently have SKSpriteNode boundaries on the edges of the screen, linked with a contact delegate to notify

I'm using a sequence to run a list of SKActions. What I want to do however, is run an SKAction, then run two at once, then run one in sequence. Here is my code: SKNode *ballNode = [self childNodeWithName:@"ball"]; if (ballNode != Nil){ ballNode.name = nil; SKAction *delay = [SKAction waitForDuration:3]; SKAction *scale = [SKAction scaleTo:0 duration:1]; SKAction *fadeOut = [SKAction fadeOutWithDuration:1]; SKAction *remove = [SKAction removeFromParent]; //put actions in sequence SKAction *moveSequence = [SKAction sequence:@[delay, (run scale and fadeout at the same time), remove]]; //run

I have a SKTextureAtlas with about 90 PNG Images. Every Image has a resolution of 2000 x 70 pixel and has a size of ~1 KB. Now I put this images from the Atlas into an array like this: var dropBarAtlas = SKTextureAtlas(named: "DropBar") for i in 0..<dropBarAtlas.textureNames.count{ var textuteName = NSString(format: "DropBar%i", i) var texture = dropBarAtlas.textureNamed(textuteName) dropFrames.addObject(texture) } Then I preload the array with the textures in didMoveToView: SKTexture.preloadTextures(dropFrames, withCompletionHandler: { () -> Void in}) To play the animation with 30 fps I use

I would like to interrupt the sequence below for 2 seconds and resume to where it would have been if it wasn't interrupted in the first place. For example, from the code below, if I were interrupt the sequence for 2 seconds by making the sprite visible from 1.5 - 3.5 seconds into the sequence (meaning that 1 second the hideInterval action plus the showSprite action, and 0.5 seconds of the showInterval action would be missed) the interruption would end at 2.5 seconds remaining for the showInterval action. How can I get the sprite to run an action on the remaining 2.5 seconds and continue with

How do I get a SKNode to move forward? I've been able to get the node to move in a fixed direction using [SKAction moveByX:y:duration:] but I want it to move in a direction relative to the direction its facing. I am looking to make each node turn 45 degrees then "walk" forward 50 pixels. It seems simple enough I just am not able to find it. This will rotate, then towards where you tap -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { for (UITouch *touch in touches) { for (UITouch *touch in touches) { CGPoint location = [touch locationInNode:self]; CGPoint diff = CGPointMake
