cocos2d-x 畫一個有邊框的矩形

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); //畫填充矩形

	glColor4ub(0, 0, 255, 255);
	glVertexPointer(2, GL_FLOAT, 0, vertices);
	glDrawArrays(GL_LINE_LOOP, 0, 4); //畫矩形邊框
	// restore default state
	glEnableClientState(GL_COLOR_ARRAY);
	glEnableClientState(GL_TEXTURE_COORD_ARRAY);
	glEnable(GL_TEXTURE_2D);
}

　　重寫draw函數如上就ok了
