Implement:
This version requires ABC system by Cohadar, so copy the
"ABC" trigger into your map. Then you can copy the "Fade System"
trigger into your map. And you're ready!

How to use:
call FadeUnit(unit whichUnit, real transFrom, real transTo, real duration, code callback)
1."whichUnit" is the unit you fade.
2."transFrom" is the transparency where the unit fades from.
3."transTo" is the transparency where the unit fades to.
4."duration" is the duration how long the fading lasts.
5."callback" is the action which is ran after fading is finished.
call GetFadedUnit()
When used in the callback action, it returns the faded unit.
Store this unit to a local variable in the callback, before
using any waits.

History:
Version 1.0
¯¯¯¯¯¯¯¯¯¯¯
-First version.
Version 1.2
¯¯¯¯¯¯¯¯¯¯¯
-Added a part to the code, which prevents fading dead units.
Version 1.3
¯¯¯¯¯¯¯¯¯¯¯
-Added new argument, "removeAfterFade", which allows the user
to remove the fading unit after it has faded.
Version 1.3b
¯¯¯¯¯¯¯¯¯¯¯
-Handle variables are now flushed correctly.
-Made few minor changes to the code.
Version 2.0
¯¯¯¯¯¯¯¯¯¯¯
-Fully rewrote the code.
-System uses vJass, so NewGen is needed.
Version 2.0b
¯¯¯¯¯¯¯¯¯¯¯
-Fixed serious bug in the execution of the system.
-Dead units no longer fade, as they did after version 2.0.
Version 3.0
¯¯¯¯¯¯¯¯¯¯¯
-Fully rewrote the code.
-Changed order of the arguments.
-There is still a bug when same unit is faded repeatedly.
Version 4.0
¯¯¯¯¯¯¯¯¯¯¯
-Fully rewrote the code.
-Replaced "minimumFade" argument with "percentFrom" and "percentTo"
arguments.
-Removed "removeAfterFade" argument.
Version 5.0
¯¯¯¯¯¯¯¯¯¯¯
-There was one, but not public version
Version 6.0
¯¯¯¯¯¯¯¯¯¯¯
-Requires ABC (by Cohadar)
-Added "code callback" argument, which is ran after fade is finished.
-Added GetFadedUnit() function, which can be used in the callback action to get the faded unit.
Version 7.0
¯¯¯¯¯¯¯¯¯¯¯
-Rewrote the code, because it looked not made by me.
-Fixed few rare bugs
Version 7.0b
¯¯¯¯¯¯¯¯¯¯¯
-Renamed some arguments and variablesSystem Trigger
