ios7 - SKSpriteNode 在不应该弹跳的时候弹跳

Question

我正在使用新的 API Sprite Kit 开发 2D 游戏。问题在于，虽然将 Sprite 节点的恢复设置为 0，但它会反弹一点。我怎样才能完全禁用弹跳？

Answer 1

您需要为将要相遇的两个对象设置恢复原状。

    self.world = [SKNode node];
    [self addChild:self.world];

    self.backgroundColor = [SKColor colorWithRed:0.15 green:0.15 blue:0.3 alpha:1.0];

    self.physicsBody = [SKPhysicsBody bodyWithEdgeFromPoint:CGPointZero toPoint:CGPointMake(500, 0)];
    self.physicsBody.restitution = 0.0;

    self.ball = [SKSpriteNode spriteNodeWithColor:[SKColor redColor] size:CGSizeMake(40, 40)];
    self.ball.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:CGSizeMake(40, 40)];
    self.ball.physicsBody.density = 100;
    self.ball.physicsBody.restitution = 0.0;
    self.ball.position = CGPointMake(200, 300);
    [self.world addChild:self.ball];
