Programming Pokémon Showdown Damage Calculator

[gnore]

how is the chance to ?HKO calculated? If I sum the number of damage rolls that 1HKO over 16 I can get the chance to 1HKO, but when I try to account for multiple attempts my chance drifts from the calculator's %. I was dividing the HP by the # of hits & finding the chance that each attempt deals that portion of damage.
Edit: i worked it out, now just optimizing code for finding combinations of rolls that ko
https://github.com/smogon/damage-calc/blob/master/calc/src/desc.ts
when does computeKOChance recur itself?

Smeargle can't learn dark void even though it can learn it in the games. Smeargle can learn dark void, but it just can't use it.

The damage calc only deals with damage that a move causes. All status moves will be treated as dealing 0 damage.

Is there anyway to turn off the automatically calced abilities of zacian and zamazenta? I know I can change their abilities, but that is kind of annoying to have to do that every time i use them since their abilities no longer activate every time they switch in.

It looks like the calc is not correctly giving the Hadron Engine boost to non-grounded pokemon.

Using this battle's turn one as a reference (we have confirmed the stat spreads involved):

0 SpA Zapdos Thunderbolt vs. 0 HP / 4 SpD Ribombee: 157-186 (60.1 - 71.2%) -- guaranteed 2HKO (with Hadron Engine as the ability)
0 SpA Adaptability Zapdos Thunderbolt vs. 0 HP / 4 SpD Ribombee: 210-248 (80.4 - 95%) -- guaranteed 2HKO (the correct boost)
0 SpA Hadron Engine Zapdos Thunderbolt vs. 0 HP / 4 SpD Ribombee in Electric Terrain: 271-319 (103.8 - 122.2%) -- guaranteed OHKO (with Gravity in effect)

The damage roll in the battle was 91%, solidly in the middle of the Adapt and Hadron-but-not-Terrain-boosted damage range.

TL;DR: Hadron Engine should still give the 4/3ers boost to non-Grounded Pokemon in the calc even though they do not get the Terrain boost.

This is what my calc looks like. Any idea why? It does not change with my zoom or anything I have tried.

For some reason, Substitute is shown on the bottom left of the screen, when it should say Explosion. When I click the word Substitute, Explosion is highlighted in the menu that pops up.

Zapdos HP is 353 in the GSC damage calc (rather than 383). There is no HP DV value - posting here so hopefully someone can fix

There is a bug in calc of specs sylveon Hyper Voice vs Assault Vest toxtricity.

This has been noticed, will be fixed ASAP.

Could you please provide more details about the bug, like what gen you are calcing in and what the bug in question is?

You could potentially give them -1 Attack to cancel out the +1 they get from their abilities.

Gen 9. Sylveon has pixilate toxtricity has punk rock

Gen 9. Sylveon has pixilate toxtricity has punk rock

If you're referring to Pixillate Tera Blast doing more damage to Toxtricity than Pixillate Hyper Voice, Toxtricity's ability Punk Rock reduces the damage it takes from sound-based moves, including Hyper Voice.

idk if this is much of a bug but Gen 1 Kangaskhan has two UU sets built in and they're the same

This isn't a bug in how the damage calculator operates; we pull each Pokemon's sets from their Smogon analysis.
https://www.smogon.com/dex/rb/pokemon/kangaskhan/
Kangaskhan has a set that is for the current metagame, and a set for RBY UU while sleep was in the tier still. They just happen to be very similar.

 

[Chrispy Burns]

Can we get a toggle to only show default sets & a toggle to hide items, abilities, and moves that do 0 damage/ do not influence damage (TM's, run away, whirlwind)?
I hardly use the pasted sets and being able to sift through moves helps a ton.

Bug Report: When inputting any level over 100 it reverts to 100. If working as intended then this is a feature request lol.

Triple kick's shows the damage of 3 30 bp hits instead of a 10, 20, 30 bp hit

Float stone does not seem to affect calcs when used with light metal. Have not tested with heavy metal as well, worth looking into

I've had a pull request open for a while that fixes this.
