1.Cocos2d-x绘图API使用说明
class
Shape:
public
Node {
public
:
//重写
draw方法 用DrawPrimitives
virtual
void
draw(){
};
bool init(){
return true ;
}
CREATE_FUNC(Shape);
};
bool init(){
return true ;
}
CREATE_FUNC(Shape);
};
2.Cocos2d-x绘制矩形
void
Rect::draw(){
DrawPrimitives::setDrawColor4B( 255 , 0 ,216)">255 );
DrawPrimitives::drawRect(Point( 0 ),Point( 100 ,216)">100 ));
DrawPrimitives::setDrawColor4B( 255 , 0 ,216)">255 );
DrawPrimitives::drawRect(Point( 0 ),Point( 100 ,216)">100 ));
}
3.Cocos2d-x绘制填充矩形
void
SRect::draw(){
DrawPrimitives::drawSolidRect(Point( 100 ),Color4F( 1 ,216)">1 ));
DrawPrimitives::drawSolidRect(Point( 100 ),Color4F( 1 ,216)">1 ));
}
4.Cocos2d-x绘制圆形
圆心，半径，角度，分隔的线段，是否绘制一个连到中心的线
void
Circle::draw(){
DrawPrimitives::drawCircle(Point( 50 ,M_PI* 2 , true );
DrawPrimitives::drawCircle(Point( 50 ,M_PI* 2 , true );
}
5.Cocos2d-x绘制填充圆形
void
SCircle::draw(){
DrawPrimitives::setDrawColor4B( 255 );
DrawPrimitives::drawSolidCircle(Point( 50 );
DrawPrimitives::setDrawColor4B( 255 );
DrawPrimitives::drawSolidCircle(Point( 50 );
}
6.Cocos2d-x绘制多边形
顶点 顶点得数目 是否关闭几何图形
#ifndef __L01DrawingAPI__Poly__
#define __L01DrawingAPI__Poly__
#include <iostream>
#include <cocos2d.h>
using namespace cocos2d;
namespace jikexueyuan {
class Poly: public Node{
private :
Point ps[ 3 ];
public :
bool init();
void draw();
CREATE_FUNC(Poly);
};
}
#endif /* defined(__L01DrawingAPI__Poly__) */
"Poly.h"
namespace
jikexueyuan {
bool Poly::init(){
ps[ 0 ] = Point( 0 );
ps[ 1 ] = Point( 2 ] = Point( 100 );
true ;
}
void Poly::draw(){
DrawPrimitives::drawPoly(ps,216)"> 3 ,162)"> true );
}
}
7.Cocos2d-x绘制填充多边形
顶点、 顶点得数目、填充的颜色
#ifndef __L01DrawingAPI__SPoly__
#define __L01DrawingAPI__SPoly__
namespace jikexueyuan {
class SPoly: private :
Point points[ 5 ];
bool init();
void draw();
CREATE_FUNC(SPoly);
};
}
#define __L01DrawingAPI__SPoly__
namespace jikexueyuan {
class SPoly: private :
Point points[ 5 ];
bool init();
void draw();
CREATE_FUNC(SPoly);
};
}
/* defined(__L01DrawingAPI__SPoly__) */
"SPoly.h" bool SPoly::init(){
points[ 0 );
points[ 100 );
points[ 3 ] = Point( 50 );
points[ 4 ] = Point( true ;
}
void SPoly::draw(){
DrawPrimitives::drawSolidPoly(points,216)"> 5 ,216)">1 ));
}
}
8.Cocos2d-x绘制线条
起始点、目标点
void
Line::draw(){
DrawPrimitives::drawLine(Point( 100 ));
DrawPrimitives::drawLine(Point( 100 ));
}
9.Cocos2d-x绘制点
void
Points::draw(){
for ( int y = 0 ; y< 50 ; y++) {
int x= 0 ; x< 50 ; x++) {
DrawPrimitives::setDrawColor4B(rand()% 256 ,rand()% 255 );
DrawPrimitives::drawPoint(Point(x,y));
}
}
for ( int y = 0 ; y< 50 ; y++) {
int x= 0 ; x< 50 ; x++) {
DrawPrimitives::setDrawColor4B(rand()% 256 ,rand()% 255 );
DrawPrimitives::drawPoint(Point(x,y));
}
}
}
