select and launch
select and launch
This is a small script that makes tap to select, and tap again to launch.
As seen in the video with the first click the item is selected, and when clicking again the item is launched.
If you click the background, the selected item, if any, is deselected.
And, if you click an item while another one is selected, the ‘selector’ indicator moves smoothly (more or less).
A nine patch is highly recommended!! This is the sample one used in the video https://www.dropbox.com/s/xmat6pf1vy6mt5c/selectable.9.png?dl=0
Note: the original script was very simple, so I added a wizard to help in the installation process…and to make the script a bit more complex 😛
So you only need to run the script in the container (remember to check the lightning menu checkbox in the script editor) and follow the instructions.
The same to uninstall it.
