Beam powered unit Script

This is the CRPL script for a tower that runs a function(:whileBeaming) when beams fire at it and :whenBeamed when beams have fired at it for long enough

:whenBeamed
#this function happens when the FramesPerBeam frames are complete
#default is create an(indestructible) anti-creeper spore which goes to random coords, but you can change this
->numBeams1

CurrentCoords RandCoords 100 -10 CreateSpore

:whileBeaming
#this function happens whenever beams fire at the tower
#default is create some AC proportional to the amount of beams firing at the tower
->numBeams2

CurrentCoords -1 <-numBeams2 mul SetCreeperNoLower

Changelog:

Spoiler

V1.3: Added $overloads and $overloadAmt to set a possible overload to destroy the core. Use :destroyed to make it do something
V1.2: Added :whileBeaming and made core indestructible(i.e. infinite beams wouldn't destroy it)

[close]

The variable $ExtraBeamsHelp can be set to 0 or 1- if it is 0 lots of beams are like a single beam, if it is 1, extra beams help.
The variable $FramesPerAction dictates how long the tower needs to charge up before it runs :whenBeamed
The variable $overloads can be set to 0 or 1- if it is 0 it can take infinitely many beams, if it is 1 it can overload and be destroyed.
The variable $overloadAmt can be set to the amount of beams required to overload the system.

This is my first finished script, so please leave some feedback.

I update the script in this post regularly, so don't be surprised if it changes.  :)

The script is heavily commented, but if you don't follow somewhere, feel free to ask. :)

There's the script and a screenshot of the effects attached.
For the screenshot, I should clarify that I have set my AC colour to yellow.

Yay! someone else who uses yellow AC!

I like the function of the script. I think I will indeed steal it (with credit) for something else later.

;D I have already made a map with three of those scripts and uploaded it to CS.
I do have a few ideas for improvements.

One interesting edge case is that you can blow up the towers with the script attached.  So you might want to call SetUnitAttribute(Self CONST_DESTROYONDAMAGE false) or something along those lines.  Right now if you get too many Beams in range (like 70 of them) they can damage the tower more than a total of 1, which will cause the tower to destruct before it can run the script and heal itself.

Of you could leave it and some something spectacular in a :Destroyed callback :)

I fixed it by doing exactly that(Self CONST_DESTROYONDAMAGE 0 SetUnitAttribute), but that would be an interesting mechanic.  :)
I think I'm going to code a $overloads now...

EDIT: Done! It was actually 70.00007 beams, but I think that's a rounding error. See the screenshot attached for lots of beams firing.
