Customizable Wheel of items

First Bogdan Tautu wrote the script to put shortcuts in a circle, then he improved it to make a rotating one (availables in the wiki)…I decided to go a bit far modifying it. This is a customizable wheel of items. It can be improved more, but I think this is enough.

This script will use all the items in the container, that’s why I recommend to use a panel.

Challenge to scripters: can you imagine how I made to rotate the items relative to the wheel (so they always look to the center) without looking at the script?

Settings:

– X position: -1 left ; 0 center ; 1 right

– Y position: -1 bottom ; 0 center ; 1 top

– Rotation: the rotation the items will have relative to itself (recommended 0 or 180)

– Sensitivity: the velocity of rotating (the more, the faster)

Instructions:

– copy paste the script.

set it in the ‘position changed’ of the panel (or desktop).

– IMPORTANT: pin the items, and detach them from the grid.

– In the panel settings, check the ‘no scroll limit’ under scroll options.

– Wheeeeeeeel

Of course you can ask in the comments any problem you could have.

    t.setPosition(x, y);
