Question

我正在使用iOS SpriteKit构建游戏。我有一个常规UIViewController“选择器”，它可以分成第二个加载SKScene的VC。 SKScene加载SKSprites并在屏幕上通过SKAction移动它们。当我第一轮比赛时，它很有效。

完成游戏后，我们返回Chooser设置下一轮。我用相同的SKScene重新加载相同的VC。这次创建了Sprite，但SKAction没有运行。我添加了一堆日志语句来跟踪它。

以下是SKAction的代码：

NSInteger startZone = [TPMathUtilities randomOffscreenStartZone];
CGPoint startPointONE = [TPMathUtilities OFFScreenPointFinder:startZone];
NSInteger finishZone = [TPMathUtilities finishZoneFinder:startZone];
CGPoint finishPointONE = [TPMathUtilities OFFScreenPointFinder:finishZone];
NSLog(@"startPointONE = %f %f  finishPointONE = %f %f", startPointONE.x,startPointONE.y,finishPointONE.x,finishPointONE.y);
newTap.position = startPointONE;

CGFloat distanceToOffScreenPt = [TPMathUtilities distanceBetweenTwoPoints:startPointONE toPoint:finishPointONE];
CGFloat movementDuration = distanceToOffScreenPt/[[TPGameData data] tapBaseGeneratorVelocity];
NSLog(@"movementDuration = %f", movementDuration);

newTap runAction:[SKAction sequence:@[[SKAction runBlock:^{NSLog(@"starting TAP ACTIONS ");}],
                                       [SKAction moveTo:finishPointONE duration:movementDuration],
                                       [SKAction removeFromParent]]]];

这是第一轮的日志，你可以看到“开始TAP ACTIONS”

startPointONE = -50.000000 740.000000  finishPointONE = 913.000000 -50.000000

这是第二轮没有SKAction：

startPointONE = 1064.000000 440.000000  finishPointONE = -50.000000 7.000000

movementDuration = 4.601108
UPDATE after Sprite Added

我创建SKScene的代码保持不变，上面的代码不会更改。有没有猜到为什么动作在第二轮Sprite上没有激活？

SKScene重新加载后{SK}未运行
