使用方法：设计大小为320x480的时候； 例如一个Sprite在右下方，距离屏幕右方40像素，距离屏幕下方为30像素。则需要如下设置：sprite->SetScale( CCGetScaleX() ); // 应用放缩，仅仅X方向即可。sprite->setPosition( CCGetScreenPoint(-40.0f, 30.0f, CC_ALIGNMENT_RB) );那么在屏幕大小为480x800的时候，看到的效果是：sprite被放大了1.5倍数sprite在右下方，距离屏幕右方60像素，距离屏幕下方为50像素。以上一点小代码，希望对大家能有所帮助，如有建议欢迎指出。附源代码如下：#ifndef CCLayout_h__#define CCLayout_h__#include "cocos2d.h"USING_NS_CC;// design size.// you can change it yourself.#define CC_DESIGN_W (480.0f)#define CC_DESIGN_H (320.0f)inline float CCGetScaleX(){ CCSize winSize =CCDirector::sharedDirector()->getWinSize(); return winSize.width / CC_DESIGN_W;}inline float CCGetScaleY(){ CCSize winSize =CCDirector::sharedDirector()->getWinSize(); return winSize.height / CC_DESIGN_H;}inline float CCGetCenterX(){ CCSize winSize =CCDirector::sharedDirector()->getWinSize(); return winSize.width / 2.0f;}inline float CCGetCenterY(){ CCSize winSize =CCDirector::sharedDirector()->getWinSize(); return winSize.height / 2.0f;}inline CCPoint CCGetCenterXY(){ CCSize winSize =CCDirector::sharedDirector()->getWinSize(); return ccp(winSize.width / 2.0f, winSize.height / 2.0f);}enum CCAlignment{ CC_ALIGNMENT_LB = 0, // left bottom CC_ALIGNMENT_CB = 1, // center bottom CC_ALIGNMENT_RB = 2, // right bottom CC_ALIGNMENT_LC = 3, // left center CC_ALIGNMENT_CC = 4, // center center CC_ALIGNMENT_RC = 5, // right center CC_ALIGNMENT_LT = 6, // left top CC_ALIGNMENT_CT = 7, // center top CC_ALIGNMENT_RT = 8, // right top};inline CCPoint CCGetScreenPoint(float x, float y, CCAlignment alignment){ CCSize winSize =CCDirector::sharedDirector()->getWinSize(); const float scaleX = winSize.width / CC_DESIGN_W; const float scaleY = winSize.height / CC_DESIGN_H; CCPoint result; if (alignment % 3 == 0) { result.x = x * scaleX; } else if (alignment % 3 == 2) { result.x = winSize.width + x * scaleX; } else { result.x = winSize.width / 2.0f + x * scaleY; } if (alignment / 3 == 0) { result.y = y * scaleY; } else if (alignment / 3 == 2) { result.y = winSize.height + y * scaleY; } else { result.y = winSize.height / 2.0f + y * scaleY; } return result;}inline CCPoint CCGetScreenPoint(const CCPoint& point, CCAlignment alignment){ return CCGetScreenPoint(point.x, point.y, alignment);}#endif // CCLayout_h__ 本文转载于Cocos2d-x中文论坛http://cn.cocos2d-x.org/bbs/forum.php?mod=viewthread&tid=144&extra=page%3D1?
