title: LWJGL - A function that is not available in the current context was called
body: <p>I just started using LWJGL and OpenGL and I've run into a problem. I'm trying to figure out how to draw a simple line for a game I'm making using a game engine I found. </p>
  
  <p>This is the link to the engine I'm using: <a href="https://github.com/SilverTiger/SilenceEngine" rel="nofollow noreferrer">https://github.com/SilverTiger/SilenceEngine</a></p>
  
  <p>In the renderer class I tried adding this function -</p>
  
  <pre><code> 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();
  
   }
  </code></pre>
  
  <p>The error that I get  is as follows:</p>

  <p>I'm very new to this and not sure how to fix this.</p>
