Spritekit - 创建“墙" [英] Spritekit - Create a "wall"

问题描述

我想知道如何使用 spritekit 创建一堵墙.物体上的东西不能移动过去.我知道我可以使用此代码:

I am wondering how it is possible to create a wall with spritekit. Something at an object cannot move past. I know that I can use this code:

self.physicsBody = [SKPhysicsBody bodyWithEdgeLoopF​​romRect:self.frame];

...但是当我使用该代码时，我基本上也得到了一个地板".我希望物体能够穿过屏幕底部但不能离开屏幕.

...but when I use that code I basically get a "floor" as well. I want objects to be able to pass through the bottom of the screen but not be able to leave the side.

在此先感谢您的帮助！

最好的问候，路易斯.

推荐答案

听起来您需要 2 个物理体，一个用于屏幕的每一侧.尝试使用类似的东西.

It sounds like you need 2 physics body, one for each side of the screen. Try having something like.

// Left Wall
SKNode *node = [SKNode node];
node.physicsBody = [SKPhysicsBody bodyWithEdgeLoopFromRect:CGRectMake(0.0f, 0.0f, 1.0f, CGRectGetHeight(self.frame))];
[self addChild:node];

// Right wall
node = [SKNode node];
node.physicsBody = [SKPhysicsBody bodyWithEdgeLoopFromRect:CGRectMake(CGRectGetWidth(self.frame) - 1.0f, 0.0f, 1.0f, CGRectGetHeight(self.view.frame))];
[self addChild:node];
