LWJGL-调用了当前上下文中不可用的函数

Question

我刚刚开始使用LWJGL和OpenGL，我遇到了一个问题。我正试图弄清楚如何为我正在使用我找到的游戏引擎制作的游戏绘制一条简单的线。

这是指向我使用的引擎的链接：https://github.com/SilverTiger/SilenceEngine

在渲染器类中，我尝试添加这个函数-

 public void drawLine(Point point, Point point2) {

        GL11.glColor3f(0.0f, 1.0f, 0.2f);
        GL11.glBegin(GL11.GL_LINES);
        GL11.glVertex2d(point.x, point.y);
        GL11.glVertex2d(point2.x, point2.y);
        GL11.glEnd();

 }

我得到的错误如下：

我对这个很陌生，不知道如何解决这个问题。

在引擎中创建的窗口具有版本3.2的OpenGL上下文。在版本3.2中，您不能调用旧的基本绘图调用。所有绘制调用都需要使用顶点数组和缓冲区来完成。这里有一个关于如何做到这一点的教程（请记住，这是用C编写的）：绘制第一个三角形。这里是引擎的入门论坛（称为新手问题）。论坛
