Would it be possible to create a Descent-style flash missile that whites out the player's screen when it hits?

[BlasterNT]

sure.  just write a script to flash the screen (in the same manner as deathflashes, presumably) every time a certain weapon type hits the player

[Legate Damar]

I don't know scripting

[yuezhi]

can't you just make a new explosion animation?

[General Battuta]

Scripting is the way to do this, just adapt the flash script that went into either BP2 or the 3.6.12 MediaVPs (I can't recall where it actually ended up).

[Droid803]

you can do it in FRED.

just make it a tag missile and fade the screen when the player is tagged.
unless you want it for multi

no, let's not start the scripting vs. fredding thing again.

Uh, none of that is necessary. Existing script works for this as-is.

You just need to copy existing config file for weapon flashes from data\config and then add new entry for your custom missile. Again copy another entry from another weapon, like Helios. You can remove the red effect while keeping the whiteout effect. All that's left is to tune the entry to your liking.
