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.
