It seems amecs is messing with ctrl and shift keys - while you are pressing them you can't interact with world

[GameBurrow]

We recently updated our modpack (https://gitlab.com/thesociety/transportcraft-lite/-/releases/2.0.2) to MC 1.20.1 (from 1.19.2) and it seems when amecs is installed we can't use mouse clicks to interact with world while holding ctrl or shift key down.

Removing AMECS fixes this issue

Some things I also tried

• I tried reset keys to make sure nothing strange carried over from 1.19
• I tried to delete options options.amecsapi.txt
• I tried to downgrade the mod (to older 1.20.1 version)

No idea what to try here anymore as this mod is really useful.

I have found the conflicting mod in my list. Useless Reptiles
It doesn't happen if I extract the embedded library and install them manually, just if the main mod is installed.
But the mod doesn't have the github issues open.

Our modpack didn't have that mod in the list so that's not the case for us.

Yeah, I compared mine to your installed all we had in common. then add a couple more at a time.

Sounds more like amecs issue. At worst you can bind fly down key manually. And I don't have issues open on GitHub because I wanted to concentrate all of feedback at Discord. Guess it backfired

But if you still wonder what could happen: that's the code responsible for reading inputs

As you can see: all I do is read inputs. If fly down key is unbound, game will use sprint key for it instead (since sprinting when flying doesn't do practically anything anyway) (edited)

Unbinding fly down from shift+c fixes this issue.

@Pop000100, did you find the conflicting mod by removing them and testing if it works, or there's a better way to find key conflicts? I have quite a lot of mods to check through (more than 100) and even bisecting would take a while to find the conflict, so I wonder if there's something better than that. Or is there any alternative to AMECS?

Same issue. I need to press ALT + Shift instead of Shift.

--edit--
I removed the shift+* keybindings from jei and it works fine now.
