We all love her but something's wrong with her.

Here is a small list of effects and items which won't work with Mei, even if Loli already told us or if it`s logic.
(I will update the list, after playing more with her):

Acid Tears,
erohW of Babylon (if a HP-up was taken),
Ipecac,
Marked,
Analog Stick,
Pencil (does only work, when entering a Room),
Evil Eye (does only work, when entering a Room),
Piercing shots (Yes, I know),
Spectral tears (Yes, I know),
Mom's Eye
Continuum (does work, but glitchy)
The Ludovico Technique
Maw of the Void
Every kind of fused bomb(!)
The worm trinkets

Loli's Commend (cutted)

Anti Gravity
Cursed Eye
Dead Dove
Dead Eye
Epic Fetus
Epiphora
Isaac's Heart
Loki's Horns
Bouncy Tears
Homing Tears
Tammy's Head
Tiny Planet
Tough Love
The Wiz
Incubus
Epiphora
Dead Eye
Pupula Duplex
Tractor Beam
Evil Eye
Dead Tooth
Eye of Greed
Glaucoma
Eye of Belial
Ghost Pepper
Large Zit



Rag Mega's Orbitals aren't affected by her shots.
The copy of you (enemy in the womb) will always shoot.
"The Soul"Champion-enemys can't push away her tears.
Her tears can still break stuff when she's not throwing them (Stuff ≠ Enemys)

This list will be quite helpful, thanks!

Anything for the Programmer.

Another for the list, Maw of the Void doesn't seem to work with Mei, the black ring never charges. I adore the mod though, great work.

Dead tooth also doesn't work

Noticed

The easiest way to make ipecac work would be to put in a tear height down that activates upon picking up ipecac. This essentially makes your tears eplode a soon as they touch something.
This however would turn ipecac into a very risky item choice.

Another possibility would be to replicate the original arc ipecac shots had. Take the maximum distance the shot is going to travel away from mei, increase the tear height up until halfway there than reduce it to 0 on the way to said max distance, might be hard to program though.

And yes both of thos require a new tear to be spawned after the old one exploded. The new one should spawn the next time the currently empty spot passes by behind mei, otherwise it would instakill everything.

I went through and checked every relevant item. The confirmed synergies list is based on the most recent development version.

All tear variant and stat modifiers should work out of the box.

Working

I love this character, I hope the items that do absolutely nothing will be fixed soon to do Something (even if small changes that are barely noticible, better than nothing at all right?)

I don't understand what you mean with this sentence.

I was an idiot, disregard.

I think ipecac should still increas damage, reduce tears and make them poisoned and on top of all, when a tear reachs its max range it GENERATES an explosion (the tear does not explode itself)
