Casting Invis with low Contamination

[Grujah]

Not sure in which subforum should this go, so putting it here.

Can somebody share a script for the init file that does the following (if it is possible, at all):

When I try to cast Invisibility, and I have low magic contamination, the game should give me an "Are you sure?" prompt.

I usually am careful but just got a (mild) bad mutation cause I accidentally forgot to sleep the contamination off :s and don't want it to happen again.

[Sandman25]

Yes, I am really interested in it too. Unfortunately my patch for this functionality is ignored on mantis.

I think glow from invisibility and haste should appear *after* the effect is over.

I'm confused, what's your reasoning for this? Feel like I missed something.

There's a function in l_you.cc that tells you your contaim level (contaminatedl() if I'm reading the code correctly.) The problem is getting the prompt to work whenever you cast those spells, and I'm going to guess there's no way to do that because crawl code isn't designed to support Lua macros to that degree. You could do some macro magic to get around this, though. (I'd probably set it up so Invisibility and Haste are automatically assigned to Capital Letters, and then you can access them through a lua macro. Then connect the lua macro to a key in game on a per game basis and you're good to go.)

Ignore XuaXua, nobody else understands him either.

Even better would be a prompt whenever an action would take you to yellow contamination. If I haste, fight, rest a little, then want to haste again, I have no idea if another haste is going to put me into yellow contam or not. Even worse with invis, where contamination just builds while you're under the effect. It'd be nice if invis just ended right before it took you to that level of contamination, since the game doesn't give me adequate info to know whether or not it's safe.

[Sandman25]

If you want to be safe, cast Invisibility OR Haste only when you have no contamination. It's impossible to get yellow contamination by a single cast of those spells.

crawl will remember your macros between games if you save them (in game with ~s or prompted on save/death), so if the function is defined as safeinvis in your rcfile you can macro F1 to "===safeinvis" and you're set.

I understand that. But if I really wanted to, I could keep track myself of the turns that have passed since I contaminated myself, to know when it's safe, even though I still have "contam" status. So it'd be nice to either give better granularity of the contam status, or just prompt when I'm about to do something that gives me yellow contam. Otherwise optimal play would be to keep a notepad and write the turn count whenever I cast haste or invisibility, or cblink, so I know if I'm in "deep grey" or "light grey".

[Sandman25]

It will never happen. For similar reason you never know how long Death's Door will last.

Contam fading away doesn't work like that. I'm not sure of the code behind it, but it's random how long it takes to fade away, so the most severe grey contam can fade away quickly or stick around for a while. Same for the way it's gained, so you can't really say 'I had invis on for 30 turns, therefore I have X levels of contamination.' If a script could determine when it would be safe to cast invis/haste at your current power, then that would give away more information than is intended, I think.

[damiac]

Ah, well I didn't know that. So in that case, I guess the game can't tell you, you just have to gamble on getting a bad mutation occasionally, and most of the time, just 5 it away.

Yeah, but what key would you have always macroed to Invis? I don't know any way of having a multiple key macro (i.e, press "z" and then "a" to activate a maco that checks). Thanks for the -s option though, I didn't know about that.

[Leafsnail]

It would still make sense to give you a warning when you try to cast haste/invis at non-zero contamination.

[Sprucery]

With invisibility, it's not just the risk of getting a bad mutation. If you're glowing, you're not invisible.

[Sandman25]

Yes, this is why I created that patch. https://crawl.develz.org/mantis/view.php?id=8203
I don't understand why it is ignored. It does not change anything unless player modifies RC file explicitly and it is completely and carefully tested.

Here you go:

  Code:

spell_slot += Invisibility : V

{
function safeinvis()
  if you.contaminated() == 0  then
    crawl.sendkeys("zV.")
  else
    crawl.mpr("You are contaminated; press zV to cast anyway.")
  end
end
}


A quick test has this working. You might want to use a force_more on the printed message, or change it to fit an existing force_more.

[reaver]

Oh, looks like my macro development has been ninja'd by rchandra.

One last note, you can put a prompt in a lua macro, like this:

  Code:

spell_slot += Invisibility : V

{
function safeinvis()
  if you.contaminated() == 0  then
    crawl.sendkeys("zV.")
  else
    if crawl.yesnoquit("You are contaminated. Cast anyway?", true, false, false, false) then
        crawl.sendkeys("zV.")
    end
  end
end
}


Which will prompt you if you are contaminated, letting you press "y" to cast invisibility.

[Sandman25]

This version works for me.

  Code:

spell_slot += Invisibility : O

{
function safeinvis()
  if you.contaminated() == 0  then
    crawl.sendkeys("zO.")
  else
    if crawl.yesnoquit("You are contaminated. Cast anyway?", true, 'n') == 1 then
        crawl.sendkeys("zO.")
   else
     crawl.mpr("Ok, then")
   end
  end
end
}
