Newbie question btw: why in TFTD dyed area have same movement penalty as mudded after generic explosions? Does this makes water denser?
Not denser as such, but I always rationalised it as having to move a bit more carefully because you cannot see where you're going. Well,
you can see where your dudes are going, but they can't.
As for aziza's post, while it may be perceived as somewhat confrontational, I'm sure he didn't mean to step on any toes. And he does have a point (and as the thread starter I am, of course, completely unbiased). Old timers especially might like the nostalgia of playing XCOM as it originally was, warts and all. Most other improvements by OpenXCOM can be turned on/off in the mods menu, so it does feel a bit odd that this particular change should be forced. And Steam/DosBox are really not an option on modern systems, as the scroll speed makes it practically unplayable - in DosBox you can slow it down, but it will never be as it was on a good old 486.
Also, the ufopaedia entry is simply not correct:
"Dye Grenades are to all intents and purposes, useless. Arguably not a bug, but it should not have survived basic playtesting. Weak weapons (eg Dart Gun) are one thing, but Dye Grenades are pointless because they never generate enough of a screen to block visibility. The best they would do is reduce alien visual range from 20 to 17. There would be a strong case to fix the strength of the Dye 'explosion' upward from 10 to 60 (like the Smoke Grenade) or at least 30-40."As one can see from aziza's screenshots, they provide plenty cover - you just got to give them a little time, which is only realistic. It's not a bug, it's not an oversight. The fact that there is a spread dynamic tells us this was an intended feature.
Oh, and by the way, damage=60 means it reaches maximum spread immediately. At any lower setting I take it the dye will take 1-4 turns to spread to this level. Is there a way to modify this? Maximum range, turns to reach said range... As far as I'm aware, the dye grenade is the only item that has this dynamic at all. Fires certainly don't seem to spread the same way.
