Dots and Distance
This is yet another thing that I am apprehensive about talking about.
When I got to thinking about these things, I got confused. When I quit
thinking about it, it made sense again. So then I thought about it some
more and sorted it all out.
This is one of my great mistakes, and I hope you don't make it after
I point it out.
Back to these two graphics. The target graphic and one Displaced to grab
the white dot in the lower-right.

In the first examples, the white dots in the coloured circles were grabbed.
Just so you know, it's a distance of 50px to those white circles. Then,
when we started using diagonal Grabitude with the same percentages, the
other white dots were grabbed. Why is that?
|
Basically
because distance of Grabitude is measured in x and y separately - not
rho (angle) and theta (distance).
Consider this:
Horizontal 39% and Vertical 0% grabs 50px horizontally.
Horizontal 39% and Vertical 39% grabs 50px horizontally and 50px vertically
(which has a theta of 70px).
|
Horizontal and Vertical are separate calculations. That's why the white
dot was grabbed and not the black circle.
I hope I didn't just give you my problems by talking about my problems.
Talk about counter-productive. Fancy that. However, I did feel it worthy
of mention. Best of luck to you.
