SKPhysicsBody与SKSpriteNode

Question

我尝试在两个节点之间建立联系，代码如下：

SKTexture *bgTexttureRiverLeft = [SKTexture textureWithImageNamed:@"River_Left_Main"];
bgTexttureRiverLeft.filteringMode = SKTextureFilteringNearest;
SKSpriteNode *spriteRiverLeft = [SKSpriteNode spriteNodeWithTexture:bgTexttureRiverLeft];
spriteRiverLeft.texture.filteringMode = SKTextureFilteringNearest;
spriteRiverLeft.anchorPoint = CGPointZero;
spriteRiverLeft.position = CGPointZero;
spriteRiverLeft.zPosition = -10;
spriteRiverLeft.name = @"River_Left_Main";


spriteRiverLeft.size = CGSizeMake(spriteRiverLeft01.size.width *0.8, _screenSize.height);

spriteRiverLeft.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:CGSizeMake(spriteRiverLeft.size.width*1.85, spriteRiverLeft.size.height*2)];
spriteRiverLeft.physicsBody.categoryBitMask = river_left_Category;
spriteRiverLeft.physicsBody.collisionBitMask = kajakCategory; 
spriteRiverLeft.physicsBody.contactTestBitMask = kajakCategory ;
spriteRiverLeft.physicsBody.dynamic = YES;
spriteRiverLeft.physicsBody.allowsRotation = YES;

[self addChild:spriteRiverLeft];

因为SKTexture River_Left_Main不是一条直线（扭曲的河流），皮划艇和河边之间的接触在某些地方是完美的，而不是那个完美的另一个地方（太晚或太早）。

我的问题是如何使联系更精确？提前谢谢。

CGMutablePathRef path = CGPathCreateMutable（）;

就是答案。很多工作，但你必须做你必须做的事情！
