在相同的情况下返回到以前的场景

Question

我有一个GamePlayScene，当结束时，删除所有节点并显示得分和重新启动的选项。我也有一个按钮在那个场景，带你到另一个场景，以显示可升级的项目。我想要创建一个函数，在“升级项目”场景中添加一个后退按钮，将我返回到结束的GamePlay场景。我现在拥有的代码将我返回到GamePlay场景，但是将重新启动游戏，而不是在文本上显示游戏。我试过在网上搜索，但我找不到一个好的解决办法。我的守则：

GamePlayScene.m

    -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
                ...
        else if (self.restart) {
                [[GameState sharedInstance] saveState];
                if ([node.name isEqualToString:@"UpgradesButton"]){
                    UpgradeShipScene *upgradeScene = [UpgradeShipScene sceneWithSize:(self.frame.size)];
                    SKTransition *transition = [SKTransition fadeWithDuration:0.5];
                    [self.view presentScene:upgradeScene transition:transition];
                }
                ...
    }

UpgradesScene.m
-(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:@"BackButton"]){
            for (SKNode *node in [self children]){
                [node removeFromParent];
            }
            GamePlayScene *scene = [GamePlayScene sceneWithSize:self.view.bounds.size];
            SKTransition *transition = [SKTransition fadeWithDuration:0.5];
            [self.view presentScene:scene transition:transition];
        }
}

您可以使用SKNode作为“假”SKScene，然后使用SKAction将其动画化(呈现或隐藏)。
