你如何使CCSprite显示为像星球大战介绍那样倾斜？ [英] How do you make a CCSprite appear as slanting like the star wars intro?

问题描述

倾斜x和y坐标不会产生这种效果。任何想法如何实现这种效果？我已经使用cccamera，但没有示例如何正确实现这一点。这个图片btw来自cocos2dx试过c ++代码仍然没有工作

Skewing x and y coordinates doesn't give that kind of effect. Any ideas on how to achieve this kind of effect? I already use cccamera but there are no examples on how to properly implement this. This image btw is from cocos2dx tried the c++ code still didn't work

推荐答案

我觉得我需要分享这一次。所以这是相机的工作原理，当你想要倾斜，45度或pseudo3d视图的背景：

I feel I need to share this once and for all. So this is how camera works when you want a slanting ,45degree or pseudo3d view of your background :

首先设置你的导演3d透视图

First set your director to 3d perspective

[director_ setProjection:kCCDirectorProjection3D];

如果你只想让一些sprite出现这种方式，那么记住
所有节点有照相机（cocos2d v.3似乎没有它，我不知道为什么）
所以你这样做：

If you only want some of the sprites to appear this way then remember this all nodes have camera (cocos2d v.3 doesn't seem to have it anymore I don't know why) so you do this:

[mysprite.camera setEyeX:0 eyeY:-40 eyeZ:10];
[mysprite.camera setUpX:0 upY:0 upZ:1];
