SpriteKit : 나는 아직도 spritekit 슈퍼 멍청한 놈이야 Stickman의 바운스

Question

을하고 여기 저기 몇 가지 튜토리얼을 얻으려고 .. 내가 높은 건물의 이동이 같은 Stickman의 그림을하기 위해 노력하고있어

지상 노드

노드가 원

의 physicsbody 공은 그러나 구형의 물리학 몸을하려고 할 때 ...이 반송되지 않을 때 잘 작동을 쳤을 때와 반송 .. 난이 코드 snipt을 시도했습니다

중력 세계의

SKSpriteNode * victim = [SKSpriteNode spriteNodeWithImageNamed:@"victim_base"]; 
    victim.position = CGPointMake(5, 500); 
    victim.zPosition = 2; 
    victim.name = @"victim"; 
    victim.xScale=0.7; 
    victim.yScale=0.7; 
    [self addChild:victim]; 

    CGFloat offsetX = victim.frame.size.width * victim.anchorPoint.x; 
    CGFloat offsetY = victim.frame.size.height * victim.anchorPoint.y; 

    CGMutablePathRef path = CGPathCreateMutable(); 

    CGPathMoveToPoint(path, NULL, 13 - offsetX, 59 - offsetY); 
    CGPathAddLineToPoint(path, NULL, 43 - offsetX, 58 - offsetY); 
    CGPathAddLineToPoint(path, NULL, 38 - offsetX, 3 - offsetY); 
    CGPathAddLineToPoint(path, NULL, 7 - offsetX, 3 - offsetY); 

    CGPathCloseSubpath(path); 
    victim.physicsBody = [SKPhysicsBody bodyWithPolygonFromPath:path]; 
    victim.physicsBody.friction = 0.0f; 
    // 4 
    victim.physicsBody.restitution = 1.0f; 
    // 5 
    victim.physicsBody.linearDamping = 0.0f; 
    // 6 
    victim.physicsBody.allowsRotation = NO; 

    [victim.physicsBody applyImpulse:CGVectorMake(10.0f, -10.0f)]; 

그리고 설치가

self.physicsWorld.gravity = CGVectorMake(0.0f, 0.0f); 
// 1 Create an physics body that borders the screen 
SKPhysicsBody* borderBody = [SKPhysicsBody bodyWithEdgeLoopFromRect:self.frame]; 
// 2 Set physicsBody of scene to borderBody 
self.physicsBody = borderBody; 
// 3 Set the friction of that physicsBody to 0 
self.physicsBody.friction = 0.0f; 

하지만 그는 점프 그냥 정말 잘못된 here.any 무엇인지 알아낼 수 없습니다 결코

을 수신 거부와 함께 지상에 여전히 남아있다 도움을 주시면 감사하겠습니다.
