It works as intented most of the time, and because of that, it absolutely destroys with technology.
Good mod

does this work with repentance? before I shatter my game.

I have found a potentially fatal issue. Bombs fired by Dr. Fetus are not recognized as tears, and can be fired infinitely quickly. Combine this with 20/20, Glitter Bombs, and Sad Bombs, and you have a broken game.

Item sprite is a bit iffy, but the concept is amazing and balance is very good. It adds a whole new dynamic to the game, and the earlier in the run you get it, the better it is. I really enjoy this item and screwing around with the synergies it has. Thanks for making it!

yeah crazy nufodib, like you can do better, all you do is ask everyone to do a gay fairy trinket. And its worse than this.

Great idea for a item, but the item sprite looks a tad iffy.

I feel bad for the person who finds this with spectral tears, has billiards, and accidentally shoots 1 over a rock... with ground based enemies.

They softlocked themselves if they don't have bombs.

i cant believe have 4 stars this item seens good but if you can shot if the tear not over is your death specially on places that you need stay on longer range xD looks like woster cursed eye

if someone gets it
RIP RUN XD that item is so bad

If someone gets eyeball tears...
RIP RUN

The sprite looks more like a centipede.

I really like it! Actually unique and adds a bit of a challenge while also be able to help

Personally I'd like it if it also gave a nice shot speed bonus. As it stands this item is more of a hassle than something useful :/

Looks like a great item! I'd love to see it added in a future booster pack!

If it was 3 maximum shoots instead of 1 on screen, it would be based on Megaman?

Ok, that's enough. I'll give it a shot in the (hopefully not far) future.

you return some value or false, that's about it
example code
function mod:onInput(entity, hook, action)
if entity then
local player = entity:ToPlayer()
if player and player:HasCollectible(CollectibleType.COLLECTIBLE_) then
if action >= ButtonAction.ACTION_SHOOTLEFT and action <= ButtonAction.ACTION_SHOOTDOWN then
if hook == InputHook.GET_ACTION_VALUE then
return 0
else
return false
end
end
end
end
end

I tried that with MC_INPUT_ACTION, but I couldn't figure how to prevent the firing. Is there an special return value or something?

What a unique mod idea, good work man!

ModCallbacks.MC_INPUT_ACTION lets you completely ignore fire actions and lets you override them with your own; this is how I implemented my own charge attacks that override mom's knife and brimstone

If you care to explain the details...

¿How could I exactly prevent the standard firing? I'd need a callback for that, and AFAIK there is none. That's the problem I said in my last post. Maybe there is some non-trivial method I don't know about...

Also, if I overcome that and implement my own firing behavior for every tear the game creates, chances are that lots of things stop working properly.

¿Suggestions or examples?

you can prevent the fire action from happening and override it with your own behavior through firetear and such

Yes, I contradicted myself with cursed eye. The method I use to prevent the tears (resetting tear delay) doesn't work with charged items right now, since the firing they do uses different code than standard tear firing.

That can change if the devs add more types of callbacks to the Lua API, but currently cursed eye doesn't behave as expected and I don't know how I could do it (maybe it's possible, but I don't have the time).

Thanks for the heads up. I'll change the description to reflect the actual behavior.

(i.e. Brim and Millipede gives you a tear delay reduction of some type.

This is what happens when you chocolate milk brimstome IIRC.

... Isn't cursed eye a charged item?

If it's easy, I'd add a bonus if you manage to break the synergy.

Thanks for the comments

I put you on my daily mod video. Keep up the good work.

reminds me of old C64 shmups

You should give the item double outlines since that is one of the atstyle rules in isaac.
Besides that it is a very intresting mechanic and a good idea.
