I think you don't really understand what I ask : I (now) know how to draw every line I want, even vertical ones.

I just suggest you update the FIRST example of this thread for future people who would want to do the same thing, and will eventually don't understand why it does not work when X1=X2 because the actual solution is given further in the thread. I know it's only 3 post further but let's be practical and give a actually working guide at the begining.

We'll have to see if JSMorley will make that change... :x

Sorry for misunderstanding your request, I agree it would be helpful for future readers of this thread... :thumbup:

If I'm not wrong eclectic-tech, mistic100 is not talking about jsmorley's initial code, but your initial code, with the supposed issue. Am I right mistic100?
If I am, here it is:

Code: Select all

; This skin draws a center red point and draws lines to random secondary points every 3 seconds
; Corrected to use different formula for LineLength and eliminate drawing error

Sorry you are wrong, I am actually talking about @jsmorley code, which is, I repeat, the first thing people see, when reading this thread.

As you said earlier, @eclectic-tech already includes the fix.

I think I properly fixed the code blocks in the first post of the thread... ;-)
