如何在cocos 2d中移动背景 [英] How to move background in cocos 2d
问题描述
您好，我想开发像涂鸦跳的游戏。但我有一些问题与以下功能 -
Hi i want to develop game like 'Doodle jump'.But i have some problem with the following features-
1.如何移动背景场景/图像。
1.How to move background scene/image.
2.如何检测对象之间的碰撞。它需要一个物理引擎像box2d或i应该只使用手动碰撞。
2.How to detect collision between object.Is it needed a physics engine like box2d or i should just use manual collision.
3.应该是背景图片的大小。
3.what should be the size of the background image.
4.其实我不知道背景是如何移动的。我需要一个解释
4.In fact i have no idea how does background move .So i need a explanation from someone.

背景移动
A） TMX Tilemap然后做出非常高的Tiled-Map。
B）您可以创建一个纹理，然后循环纹理坐标，而不是真正移动它。
Background Movement A) You could create a TMX Tilemap and then make a very high Tiled-Map. B) You could create one texture and then cycle the texture coords instead of really moving it.
手动检测。最好通过边界点或矩形检测。
有关详情，请访问我的博客条目，以便与cocos2d进行碰撞检测： http：// www .anima-entertainment.de /？p = 262
Detect it manually. Best is detect it via "Point in Boundingbox" or "Rect in Rect". For more detail visit my blog entry for collision detection with cocos2d : http://www.anima-entertainment.de/?p=262

请记住，的2在内存中。如果你想创建一个背景图像在视网膜高分辨率（960x640像素）在内存中将是一个1024x1024的纹理。如果可能使用较小的背景图像并拉伸它们。 （如512x512）。
Size of an Image Keep in Mind that textures are always at power of 2 in the memory. If you want to create one Background-Image at retina highresolution (960x640 Pixel) in the memory will be a texture of 1024x1024. If possible use smaller Background-Images and stretch them. (like 512x512). But I really would recommend for big scrolling images the TMX Support.
CCTMXTiledMap * tmxNode = [CCTMXTiledMap tiledMapWithGMXFile：@Level.tmx ];
//假设您想在1秒内将其移动50像素：
[tmxNode runAction：[CCMoveBy actionWithDuration：1.0 position：ccp（0，-50）];
要创建拼贴图： http：// www。 mapeditor.org/
