While the idea of full control over the limit, even without exceeding the instruction to be behind a symmetric NAT, then game.net.gen_peercode will also have different colors.

Welcome the Cube. The Cube, as you might know, is made of six squares. A square is made of two triangles, and those two triangles share 2 of 3 common vertices. As a triangle is made of three vertices, this means we must pass 36 vertices in order to get the full shape, when using GL_TRIANGLES.

Now while you can use GL_QUADS and push six quads (24 vertices) instead, I will be using triangles because they'll grow increasingly important anyway. A cube isn't really a real-world use case.

Square on a plane.

static float hsz = 0.2; //Half-size

glBegin(GL_TRIANGLES);
	glColor3f(1, 1, 1);
	
	// Square on -Z plane
	glVertex3f(-hsz, -hsz, -hsz);
	glVertex3f(+hsz, -hsz, -hsz);
	glVertex3f(-hsz, +hsz, -hsz);
	
	glVertex3f(-hsz, +hsz, -hsz);
	glVertex3f(+hsz, -hsz, -hsz);
	glVertex3f(+hsz, +hsz, -hsz);
	
	// On -X plane
	glVertex3f(-hsz, -hsz, -hsz);
	glVertex3f(-hsz, -hsz, +hsz);
	glVertex3f(-hsz, +hsz, -hsz);
	
	glVertex3f(-hsz, +hsz, -hsz);
	glVertex3f(-hsz, -hsz, +hsz);
	glVertex3f(-hsz, +hsz, +hsz);
	
	// On -Y plane
	glVertex3f(-hsz, -hsz, -hsz);
	glVertex3f(+hsz, -hsz, -hsz);
	glVertex3f(-hsz, -hsz, +hsz);
	
	glVertex3f(-hsz, -hsz, +hsz);
	glVertex3f(+hsz, -hsz, -hsz);
	glVertex3f(+hsz, -hsz, +hsz);
glEnd();

Would he kill himself, no one on the server state is inevitable.
