Pausing a sprite kit scene

问题

@property (SK_NONATOMIC_IOSONLY, getter = isPaused) BOOL paused;

I found this line of code that I could add into my project, how would I pause my whole game?

For example:

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
for (UITouch *touch in touches)
{
    SKSpriteNode *pause = (SKSpriteNode*)[self childNodeWithName:@"pause"];
    CGPoint location = [touch locationInNode:self];
    // NSLog(@"** TOUCH LOCATION ** \nx: %f / y: %f", location.x, location.y);

    if([pause containsPoint:location])
    {
        NSLog(@"PAUSE GAME HERE SOMEHOW");
    }
}

}

As you can see, I have the button set up. When i select it, how would I pause the whole scene? And then resume it when someone hits a resume button.

OK SO I got some advice to call

  self.scene.view.paused = YES;

except here is the problem, in my app delegate

- (void)applicationWillResignActive:(UIApplication *)application{


SKView *view = (SKView *)self.window.rootViewController.view;
view.paused = YES;}

and

- (void)applicationDidBecomeActive:(UIApplication *)application{

    SKView *view = (SKView *)self.window.rootViewController.view;
    view.paused = NO;

I make it a type SKView, when it is actually an SKScene. Anyway to fix this? Do you suggest that I make all my scenes into views by retyping all the code?

回答1:

Use SKView's paused property:

Swift:

scene.view?.paused = true

Objective C:

self.scene.view.paused = YES;

This will stop all actions and physics simulation.

回答2:

Use Scene to Paused Functionality

self.scene?.view?.paused = true
