Can Swift miss in RBY?

Crystal_ · 2013-04-25 17:47:28

Simple question, but I haven't been able to find a conclusive answer in the net. My theory was that Swift could miss, that the only difference in its effect was that it doesn't do the acc/evasion check, but that it still does generate the random number and compare it to its accuracy etc, so that the 1/256 miss probability was still there.

I tested it in Pokemon red changing Swift's accuracy byte to 0x01, but to my surprise, Swift hit everytime so now my theory is that Swift skips everthing and always hits. But I'm not 100% certain! Curiosity thing mostly, but anybody knows, for sure, whether Swift can miss or not?

swift hasn't exactly the 100% of chance to hit the enemy, it's a lil bit lower (about 99.something%), infact time ago I missed with swift while playing in the cartridge and I said "impossible!" because, as you said, the chance of failure is very low, but it exist.

So are you sure then? I know about the 1/256 bug that affects every "100%" accuracy move, but I didn't know if it affected Swift as well. So, as far as I have seen then, it seems that when Swift is used, the game compares the random number between 0 and 255 always with an accuracy value of 255, regardless of the move's accuracy and the evade/acc modifiers of the pokemon. But it seems then that the comparison still happens in the hitprobability calculation, causing the move to have a chance to miss.

Yes, I've encountered that even on a cartridge, I knew since that moment it was possible.

Its not 100%,
its 99,6% exactly ._.

yep, Infact I said 99.(something)%, it seems being 0.6.

chances of hitting are 255/256
same with the masterball in gen 1

About Masterball Failure... I made a small movie with MISSINGNO. in main role - http://www.youtube.com/watch?v=komk7GPr … g&index=39 - I show here as 000 <Oryginal KETSUBAN/MISSINGNO. number > It can break Master Ball...

It doesn't have accuracy.

Crystal_ · 2013-04-28 11:24:48

It doesn't have accuracy.

What do you mean by that? Swift does actually have an accuracy value hardcoded, which is 255. Do you mean that Swift's effect causes the move not to use its acc value in the HitProbability calculation? If so, that's my theory too.

he maybe meant master ball

It doesn't use the calculation, probably. Unless the Detect/Protect comes to play, it will eventually miss. Having the accuracy value of 255 can still be modified by accuracy lowering attacks (or it's actually the value that tells the game not to make it miss whatever happens) so I guess Swift can be an exception to the games engine accuracy calculation.

Nice guess but, nope.

Apparently neither Swift or X Accuracy boosted moves are affected by the 1/256 bug. Did you remember it wrong 80C?

Maybe, as someone said before, Swift could lower its accuracy after some attacks that lower precision.
This is probability, 1\255 doesn't mean that it can't happen, there are people that got their good probability and catched reshiram with a pokeball at the first try or people that didn't catch taillow after 5 mega balls one each turn.

Well... I wonder about Missing if is able to restore "You missed Pokemon" from RBY to GSC.

it skips those checks

reshiram and zekrom have mad high catch rates on par w/ first-route mons

Even A.T. was mentioned on glicthcity coz a missing Swift is very unsual!
