* Optimizations with private, params, and isEqualType
* Fixed tab being used instead of space
* Fixed tabs inserted by notepad++
* More usage of new private syntax and params
- changed a few checks for an array being empty to `_arr isEqualTo []`
rather than `count _arr == 0`
- added more uses of `private` on the same line as the variable is
declared
- added more uses of params to assign variables passed as parameters
- removed unnecessary parentheses
- removed several unnecessary variable declarations with private array
syntax
* clean up and formatting
Reduce the time between automated refreshing of the unit tree. Also makes an initial call to the tree populating code upon first opening to remove the initial delay.
- Account for decrement in node index when culling the tree of sides/groups/units
- Fix non-zero-based index `to` value when navigating the units in the tree
Minor oversight introduced in pabst's fix for #2989, the icon handler is a mission event handler that isn't self terminating so the index needs to be preserved until after it is removed via `removeMissionEventHandler`. It is safe to let the `onUnload` event take care of that (and preferable so that icons disappear while temporarily closed).
This allows me to explicitly close the right display and hopefully fix the interface staying open upon mission end.
@Commy2's theory is that perhaps the main display `46` is killed upon mission end, meaning that `findDisplay` can't find the spectator display to close it because the game thinks it doesn't exist.
Should fix#2989
There is a race condition between these 4 PFEH and the "onUnload" event
in handleInterface.
If the PFEHs run first they will use nil variables and throw a script
error.
This sets them to nil immediately when exiting spectator
Turns out custom radio channels are kind of a pain to work with. However this should work fine assuming the radioChannelAdd commands will work on client machines.
