下载代码包括:
GeometricRecognizer.h
GeometricRecognizer.cpp
GemetricRecognizerTypes.h
GestureTemplate.h
PathWriter.h
SamplesGestures.h
使用示例:
1.你的Layer需要实现以下两个方法
virtual void ccTouchesMoved(CCSet *pTouches, CCEvent *pEvent);
virtual void ccTouchesEnded(CCSet *pTouches, CCEvent *pEvent);
2.初始化GeometricRecognizer来加载你的手势模板
private:
GeometricRecognizer* g_rGemertricRecognizer;
//加载模板
rGemertricRecognizer=new GeometricRecognizer;
rGemertricRecognizer->loadTemplates();
3.记录触摸操作(玩家在手机上所做手势的路径)
//声明一个坐标集合
private:
Path2D p_2dPath;
//Layer的ccTouchesMoved方法中记录坐标
CCSetIterator it = pTouches->begin();
CCTouch* touch = (CCTouch*)(*it);
CCPoint location = touch->locationInView(touch->view()));
Point2D p_Point2DTemp;
Point2DTemp.x=location.x;
Point2DTemp.y=location.y;
//记录
p_2dPath.push_back(Point2DTemp);
4.通过GeometricRecognizer校准
//Layer的ccTouchesEnded方法中, 下面屏蔽玩家单击操作
if (p_2dPath.size() < 1){
return ;
}
RecognitionResult result = GemertricRecognizer->recognize(path2d);
//RecognitionResult 结果
class RecognitionResult
{
public:
string name;
double score;
RecognitionResult(string name, double score)
{
this->name = name;
this->score = score;
}
};
//这个类会保存你的自定义的模板名称(name未找到会回返回Unknown)和相似度(score 0.0-1.0)
