FLASH=[hexvalue,time in secs]
Now before you use it, click on the NODE button. At the bottom left of the screen is a color box and four bars. Click on the bars to find the color AND alpha you want. Look at the text that says color=. That is your 8 digit value. To fade to black use 000000FF.
Ex.
Flash=000000FF=1 (fades to black in 1 second)
Flash=00000000=.2 (fades BACK to normal) --- YOU MUST USE THIS COMMAND at end of script, UNLESS there is a map change. Map changes will reset the screen.

Flash=FF340034=2

Now to get a different look to the flashes you can add a nice Overbright look to it. It’s permanent, so you MUST SET IT BACK TO ZERO AT END OF SCRIPT! It does not work with full black.

FLASHSTYLE=[1 is alpha type, 0 is regular type]

Ex. over time
Flashsytle=1
Flash=FF340034=2
Flash=00000000=2
Flashsytle=0
