雪碧套件 - 创建拱路径SKSpriteNode给予滑动手势 [英] Sprite Kit - Create arch path for SKSpriteNode given a swipe gesture

问题描述

我想提出一个简单的游戏，用户刷卡向上的对象（SKSpriteNode）发送它上下在拱形的议案（使用SKAction我假设）。下面是一个视觉什么我希望能完成（请原谅我的基本技能Pixelmator）的：

I am making a simple game where the user swipes upward on an object (SKSpriteNode) sending it up and down in an arching motion (using a SKAction I assume). Here's an visual of what I'm hoping to accomplish (please forgive my basic Pixelmator skills):

我创建了向上发送对象的SKAction并计算基于速度，等刷卡的最后一点但是，我无法弄清楚如何使足弓运动出现一次到达终点，也没有回落到在屏幕的底部。我希望我可以添加重力对象和雪碧套件将处理对象的移动，但是，这并不似乎是从我的初步调查结果的情况下。

I have created an SKAction which sends the object upwards and calculate the final point of the swipe based on velocity, etc. But, I cannot figure out how to make the arch motion occur once the final point is reached nor fall back to the bottom of the screen. I am hoping that I can add gravity to the object and Sprite Kit will handle the movement of the object, but that doesn't appear to be the case from my initial findings.

我已经张贴我目前的code位置：

I've posted my current code here:

该应用程序是基于关闭此教程：

The app is based off this tutorial:

在code是写在Xamarin / C＃，但几乎是相同的Objective-C的等效。如果你需要/想我将它转换成Objective-C的我现在最肯定可以。

The code is written in Xamarin/C# but is almost identical to the Objective-C equivalent. If you need/want me to convert it to Objective-C I most certainly can.

感谢您的所有先进的帮助，如果我能提供任何进一步的信息，请让我知道。

Thank you all in advanced for your help and if I can provide any further information please let me know.

推荐答案

结束了使用物理为基础的方法。我通过iOS的雪碧套件编程指南帮了不少忙了（去图）。

Ended up using the physics based approach. I went through the iOS Sprite Kit programming guide which helped quite a bit (go figure).

每@ LearnCocos2D和@doctorBroctor我想出了似乎是工作不够好解决方案。我更新了我的github上的项目，如果有人绊倒在这个职位，并寻找一些code。

Per @LearnCocos2D and @doctorBroctor I came up with the solution that seems to be working well enough. I updated my github project if anyone stumbles upon this post and is looking for some code.

谢谢大家！

PS - 我不知道如何来纪念这个，因为我用了两个反应/答案件。所以我创造了这个答案与解释和上投两种反应。如果有一个更好，更公平的方式，以纪念这个问题，我洗耳恭听。

PS - I wasn't sure how to mark this since I used pieces of two responses/answers. So I created this answer with explanation and up-voted both responses. If there's a better and more fair way to mark this question I'm all ears.
