충돌 감지 후 끝 화면 표시

Question

첫 번째 스프라이트, 다람쥐 및 두 번째 스프라이트 인 도토리/너트가 충돌 한 후 GameOverScene을 사용하려고합니다. 지금은 두 스프라이트가 충돌 할 때 다람쥐가 화면에서 떨어집니다. 다람쥐가 화면에서 떨어지지만 끝 화면이 나타나길 바래. 나는이 말을하고이 페이지에서 시작 화면에 대한 자습서를 사용하여 시도

-(void)didBeginContact:(SKPhysicsContact *)contact 
{ 

SKPhysicsBody *firstBody, *secondBody; 

firstBody = contact.bodyA; 
secondBody = contact.bodyB; 

if(firstBody.categoryBitMask == squirrelHitCategory || secondBody.categoryBitMask == nutHitCategory) 
{

-(void)didBeginContact:(SKPhysicsContact *)contact 
{ 
    SKPhysicsBody *firstBody, *secondBody; 

    firstBody = contact.bodyA; 
    secondBody = contact.bodyB; 

    if(firstBody.categoryBitMask == squirrelHitCategory || secondBody.categoryBitMask == nutHitCategory) 
    { 
     [self gameOver]; 
    } 
} 

- (void)gameOver 
{ 
    GameOverScene *gameOverScene = [GameOverScene sceneWithSize:self.size]; 
    [self.view presentScene:gameOverScene transition:[SKTransition pushWithDirection:SKTransitionDirectionLeft duration:0.5]]; 
}
