Script - Flashy Deaths (new)
From FreeSpace Wiki
Function
New version of the flashy deaths effect by Wanderer. You may wish to check out the script's thread on HLP.
Please note that this script requires two additional files in .cfg format whose specs can be found below.

Please note that the following list isn't complete yet.
Name: defines the ship for which this entry is made for
Width: & Height: & Length: define the dimensions inside which the detonations occur
Detonation Radius: defines the radius (base radius) of the detonation effects
Detonation Effects: list of ID values of the effects (defined in the other cfg file), may have multiple ones
Detonation Multiplier: multiplier which controls the amount of explosions triggered. 0.2 is 80% decrease, 1.2 is 20% increase
Flash Radius: defines the radius of the flash when ship actually goes away
Flash Effect: ID values of the flash effect, as listed in line order entry in additional cfg

Notes
As stated above the shiplist isn't complete yet, meaning that the destruction of any ships other than the ones specified in the current expl_flashes.cfg will not trigger any effect.
