如何渲染2D横向卷轴游戏 [英] How to render a 2d side-scroller game

问题描述

我真的不理解的方式，我假设呈现一个横向卷轴？我怎么知道该怎么渲染的时候，我的性格动？我应该使用的字符是什么样的为定位的？ 我希望我的问题是清楚的。

I do not really understand the way I'm suppose to render a side-scroller? How do I know what to render when my character move? What kind of positionning should I use for the characters? I hope my question is clear

推荐答案

最简单的方法我发现做到这一点是有一个characterX和characterY变量[整数或浮点数，任何你想要的]然后有一个cameraX和cameraY变量。场景中的每个对象被绘制在theObjectX-cameraX，theObjectY-cameraY ...

The easiest way i've found to do it is have a characterX and characterY variable [integer or float, whatever you want] Then have a cameraX and cameraY variable. Every object in the scene is drawn at theObjectX-cameraX, theObjectY-cameraY...

CameraX / CameraY是由一个类似的到中间点式补间让他们最终会达到PlayerX的/ playery [CX =（CX * 99 +过氧化物酶）/ 100] ...是啊

CameraX/CameraY are tweened by a similar-to-midpoint formula so eventually they'll reach playerx/playery[Cx = (Cx*99+Px)/100] ... yeah

这样一来，每一个对象在舞台的空间移动，变换只在渲染[您节省头痛]

By doing this, every object moves in the stage's space, and is transformed only on render [saving you from headaches]
