Known Issues
  • It is possible to trade red hearts on the frame they're gained
  • Having many Ludovico tears with custom graphics is performance intensive due to the need to refresh them often

Small bug.
If you are fast enough you can use guppy's paw before the game converts the red heart into a black heart giving you three soul hearts instead of the black heart.

Just tried her out for the first time, have a bunch of other mods installed, but nothing completely game changing.

Her tears are completely white for me, but change color accordingly with other items.
Don't know if this is intended or not, but range and shot speed ups don't seem to have any effect.
Dying and respawning e.g. with dead cat causes her to lose her hair.
Her tears leave splashes everywhere, making it hard to see incoming bullets.

Also just a suggestion: It would be nice if she started with maybe one more heart, since she suffers from the same fate as Blue Baby. This is coming from somebody with 270 hours on record; sometimes it's a pain in the ass to stay alive long enough to get powerful.

Her tears are completely white, I haven't updated the screenshots and gifs though.

Range has no effect because there is no obvious formula for how range properly affects tear distance since range is a combination of Tear Height, Tear Falling Speed, and Tear Falling Acceleration.

Shot Speed increases how quickly her orbitals rotate around her.

I'm still trying to figure out the best way to do the tear spawn and expire effects without those splashes happening, but there's no apparent way to stop those animations from spawning, so it's either those annoying splashes or no tear spawn/expire synergies (Cricket's Body, Lead Pencil, Glaucoma, etc) for now.

Dying and respawning with dead cat doesn't remove her hair when she has no other items, so I can't do much about that. There's no way to simply check if she's missing a specific null costume, so there's seemingly no way to handle that at the moment since a normal costume crashes.

Thanks for the quick answer! I guess I just didn't notice the shot speed increase. As for the spawn/expire synergies, I thought those trigger with piercing upon collision anyway? Do the tears have to expire/spawn for that to trigger?
goki_dev  [developer] Jan 17, 2017 @ 3:06pm 
Lead Pencil for example occurs on every 15th shot. Most of the time you'll shoot 4 times as you enter a room (4 orbitals) meaning Lead Pencil will proc very infrequently.

Cricket's Body splashes when the tear expires which is hitting the ground in most cases.

Some other stuff is on fire, not on collision. Parasite's on collision though.

It wouldn't matter if those splashes weren't so annoying...I could technically remove all traces of those entities when playing as Mei...It's worth trying at least.

I would rather have no splash particles and see incoming projectiles than have splashes everywhere and not see ♥♥♥♥. I'd say it's worth a try ;)

I've found a nice balance of lowering the opacity of the splashes by a significant amount. That update will be out shortly.

It seems like every tear fired causes all the current tears orbiting her to splash at once, also causing an ever so slight frame drop for that moment. Is that supposed to happen?

It looks like when a player has tech 5, you reference a variable that doesn't exist (tech5Chance), which causes your tears to bug out a lot. I created the variable and everything worked fine. Just thought I'd point that out.

The Head of Krampus shoots out lasers, but the lasers do no damage to enemies. Probably along the same lines as the invincibility bug noted in OP.

E: Death tarot card also fails to do any damage

Great mod, btw! Really fun character!

The Tech.5 fix went live a patch ago, and yeah I'll have to figure out another way to make laser not deal damage when she is not firing because it's affecting too many things.

Every tear she has can only synergise with the proper tear spawn and expire effects if new tears spawn and expire (which her orbitals don't do) and that's currently done by spawning and killing a tear for each of her orbitals every MaxFireDelay frames while firing.

For now I suppose I will remove the tear expire synergies until there is a better solution.

Not sure what the implications might be, but perhaps establish the tear expiration at a fixed location? (ie. directly behind Mei, or at the apex of the ark) If it's a consistent fixed location, it would reduce the visual effect to just one image.
goki_dev  [developer] Jan 18, 2017 @ 6:52am 
The location the tear expires is where the outcome will be determined, so if it expires on top of Mei, the tears from Cricket's Body for example will spawn on Mei.

The best outcome is simply removing the splashes as they are spawned, but there's no way to get only those splashes since they don't reference the parent and enemy tear splashes are also counted as friendly. They DO maintain their spawners color so I could make them invisible, but that would make the tears that come out of Cricket's Body invisible as well, leaving only random shadows floating about like this https://files.catbox.moe/4h6im6.gif

Just played her on the newest patch, ans she's much more enjoyable! Lowering the opacity was definitely the right choice. Don't know if this is intended or not, but if you don't fire your tears they look like fires now, it wasn't like this before. Also I can confirm that Ipecac and Moms Knife work as Mei, though might be a little too OP...
goki_dev  [developer] Jan 18, 2017 @ 7:15am 
I'm trying to figure out a good way to incorporate the fires without entirely replacing the appearance of your tears. I think the fires fit her concept thematically, but only seeing the fires would not make it obvious what your tears actually are (knives, scythes, syringes, teeth, etc) which can be problematic.

Though I suppose Lost Contact and Mom's Knife already override a bunch of stuff.
