Draw Line?

#1 What you ask for:

glColor3f(0,0,0.5f);
glBegin(GL_LINES);
glVertex3f(x1,y1,z1);
glVertex3f(x2,y2,z2);
glEnd();

Probably easier:

Point3F p1;
Point3F p2;
glBegin(GL_LINES);
glVertex3fv(p1);
glVertex3fv(p2);
glEnd();

Looks best:

Vector<Point3F> mArray; // array of points the AI would be traveling.
CameraSpline spline;

for(U32 i = 0; i < mArray.size(); i++)
{
	CameraSpline::Knot::Type type = CameraSpline::Knot::POSITION_ONLY;
	CameraSpline::Knot::Path path;
	path = CameraSpline::Knot::SPLINE;
	spline.push_back(new CameraSpline::Knot(mArray[i], QuatF(0,0,0,1), 1.0f, type, path));
}

F32 t = 0.0f;
S32 size = spline.size();
if (size <= 1)
  return;
glBegin(GL_LINE_STRIP);

while (t < size - 1)
{
	CameraSpline::Knot k;
	spline.value(t, &k);
	t = spline.advanceDist(t, 2.0f);
	VectorF t1(k.mPosition);
	glVertex3f(t1.x, t1.y, t1.z + 1.0f); // display the path a little above the desired spot.
}

glEnd();

Splines are easy to make in torque, and there are excellent examples already in place. The above code was taking from worldEditor.cc and simplified a bit.

hope i helped.

#2 Sorry, I probably should have mentioned that to actually render it, you will need a class that does rendering (eg. SceneObject). Or you can make a whatever you want and have it render only when the editor is open. Have a call from the renderScene function in world editor to your object(s). There are many other ways to get something to render, but maybe i should point you to fxrenderobject. Have fun

#3 Thx for the help,
I'll take a look at fxrenderobject. A big thing I was wondering was whether or not OpenGL acknoledged Torque world space. Also, what files would I have to include, and where should I put my new file?
