Creating Line By Resizing? Active Object

[drnebula]

Quite a while ago, someone posted an example of how one could create a line between two moving active object. They did it by resizing or doing something to an active object that served as the line. Now I can't find that example post. Does anyone have a copy or know how this was done? Any help appreciated.

Likely what they did was make an active with a height of the thickness of your line, and a width of 1px. Then the events

Always:
Set Angle to 0
Set X Scale to sqr((X("Object 2")-X("Object 1")) pow 2+(Y("Object 2")-Y("Object 1")) pow 2)
Set Angle to atan2(Y("Object 1")-Y("Object 2"), X("Object 2")-X("Object 1"))

For some reason, I cannot get the code to work. I am drawing the "line" from a set point to a pendulum that is swinging back and forth. I don't get anything to show up. Any suggestions on what I could be doing wrong?
Thanks for the idea.

I am posting a sample problem in the download section. I think I've duplicated the code exactly. The scale is set to the size of the resultant of the two sides of the triangle formed by the two obects. The angle of the line is set by taking the inverse tangent of the opposite side over the adjacent side. Look under the Line group of events and tell me what I am doing wrong. I could use this idea for all kinds of things.
Thanks for the help.
