cocos2d-x 画一个有边框的矩形

void GameLayer1::draw(void)

{

    CCLayer::draw();

 

    glEnable(GL_LINE_SMOOTH);

    glLineWidth(1);

    CCPoint vertices[] = { ccp(100, 100), ccp(200, 100), ccp(200, 200), ccp(100, 200) };

 

    glDisable(GL_TEXTURE_2D);

    glDisableClientState(GL_TEXTURE_COORD_ARRAY);

    glDisableClientState(GL_COLOR_ARRAY);

 

    glColor4ub(255, 0, 0, 255);

    glVertexPointer(2, GL_FLOAT, 0, vertices);

    glDrawArrays(GL_TRIANGLE_FAN, 0, 4); //画填充矩形

 

    glColor4ub(0, 0, 255, 255);

    glVertexPointer(2, GL_FLOAT, 0, vertices);

    glDrawArrays(GL_LINE_LOOP, 0, 4); //画矩形边框

    // restore default state

    glEnableClientState(GL_COLOR_ARRAY);

    glEnableClientState(GL_TEXTURE_COORD_ARRAY);

    glEnable(GL_TEXTURE_2D);

}

　　重写draw函数如上就ok了
