Basic Line, Point and Transform Debug code

[sarbian]

Working with KSP multiple coordinate systems can be a pain and sometime a quick drawing on screen help understanding what is going on. Here is class to draw some debugging lines, point and transforms.

https://github.com/sarbian/DebugStuff/blob/master/DebugDrawer.cs

Licence : public domain. 

Calling it is as simple as a line in an Update()

DebugDrawer.DebugLine(FlightGlobals.ActiveVessel.transform.position, Planetarium.fetch.Home.transform.position, Color.yellow);

DebugDrawer.DebugPoint(Vector3.zero, Color.green);

DebugDrawer.DebugTransforms(FlightGlobals.ActiveVessel.transform);

Updated version in here DebugDrawer.cs

Thank you for this. 

I found some small problem:

I had to add this into the code:

        private IEnumerator EndOfFrameDrawing()
        {
            Debug.Log("DebugDrawer starting");
            while (true)
            {
                if ((lines.Count + points.Count + transforms.Count) == 0 )
                {
                    yield return new WaitForEndOfFrame();
                    continue;
                }

I mean the if 

Quote

                if ((lines.Count + points.Count + transforms.Count) == 0 )
                {
                    yield return new WaitForEndOfFrame();
                    continue;
                }

I got thousands GL Matrix Error as long I don't draw lines and KSP got funky after some time (Kerbin crashed) 

Is there a reason why you did't put the drawing into the unity Draw() call?

  I also extended it to use this function. 

Quote

      /// <summary>
        /// Paints the vector from the start point
        /// </summary>
        /// <param name="start"></param>
        /// <param name="vector"></param>
        /// <param name="col"></param>
        public static void DebugVector(Vector3 start, Vector3 vector, Color col)
        {
            lines.Add(new Line(start, start + vector, col));
        }

Which Draw call ?

I took the original code... Sorry for that. 

Draw() is some internal form Kerbal Konstructs. The Unity one is OnGUI().

I dont like to use OnGui for something it is not meant to do. And you have to check for the current event to avoid drawing multiple time since onGui is called a bunch of time per frame.

And I fixed DebugDrawer.cs again

In KSP 1.7.2 I can't get the DebugDrawer methods to show anything in the map view, although it seems to me the class is meant to have the ability.
Is there any trick for making that work (outside of converting the values to scaledspace scale) ?

If you don't convert to scaled space then what your are drawing will not be at the correct scale.

[Gotmachine]

I am converting to scaledspace. I'm pretty sure of what I'm doing in this aspect as I can draw my intended lines using another method.
They just don't show up when I'm using the DebugDrawer class.
Although that work perfectly fine in flight mode/scene (with non-ScaledSpace coordinates, of course ;))
