== Radiation suit penetration ==

FYI: The [[Doom source code|code]] for 20% damage reads "P_Random()<5" but the actual chance of this being true is 6/256 rather than 5/256. This is because the [[pseudorandom number generator|random number table]] has two 0's, no 1's, two 2's, one 3, and one 4 for a total of six values less than 5.

Is this comment about the suit penetration not occurring in vanilla doom actually correct?  Examining the source to prboom 2.2.6 reveals that it still has the behavior from the original Doom source code. The call to P_Random means that any 1.9 demo featuring a player walking through slime while wearing a radiation suit should go out of sync.  Prboom is renowned for its demo backwards compatibility.

In my little test level, ZDoom behaved as expected from the source code (very occasional 20% damage), but using doom.exe and doom95.exe I never got any damage while wearing the suit. (Maybe the latter have the P_Random call but don't do the damage correctly? Just speculating...) [[User:Radius|radius]] 04:48, 10 Mar 2005 (GMT)

I don't want to change the article yet if everybody's getting different results, but here's what happened when I tested this again yesterday:

PrBoom 2.2.6 <tt>-complevel 1</tt>: leaky suits.

Doom95: no leaky suits.  (At least, no damage through 8 times the duration of a suit.  Assuming I wasted 2 seconds per suit hopping in and out of the lava, the odds are 60,000 to 1 in favor of non-leaking suits.)

Vanilla (E3M6): real suits leak, but <i>not</i> suits obtained with <tt>IDBEHOLD</tt>. (Note to self: don't use cheat codes when testing levels, even in vanilla.&nbsp; :>&nbsp;&nbsp;&nbsp; So the compatibility of PrBoom is intact. [[User:Ryan W|Ryan W]] 04:25, 25 Jun 2005 (UTC)

I have now experienced leaks in both vanilla and doom95 (on E3M6, and it <i>was</i> a "cheat" suit!).  Not sure why I couldn't see them before -- goes to show you can't prove a negative. [[User:Radius|radius]] 12:22, 26 Jun 2005 (UTC)

:Well, I tried this again, and I swear I can't get the "cheat" suit to leak in vanilla.&nbsp; But, as you say, that doesn't prove much.&nbsp; :>&nbsp;&nbsp; If it leaks for you, the article (and [[Cheat code]]) should stay the way it is.&nbsp; [[User:Ryan W|Ryan W]] 07:16, 26 Sep 2005 (UTC)
