Unity Engine

EDIT: Submitted bug-report IN-14456

Unity 2019.4.20f1, Android, Input System 1.4.2

I upgraded the Input System package from 1.3.0 to 1.4.2 and now get the following exceptions every time I stop play mode. According to the stacktrace, it’s all coming from the Input System itself and not from user scripts.

How can I fix it?

I’m getting the same errors except the last one on my project. Started happening when I upgraded to 2020.3.38 from 2020.3.37, and only when I exit play mode. My input system is on 1.4.2.
I think this might be a bug.

Downgrading to 1.3.0 of the input system seems to be the work around for the time being

5

Yes, same issue here. Downgrading resolves the issues as well. If any more data is required to solve the issue, please let me know and I will provide what I have in addition to Peter77’s report.

How do you downgrade a package?

7

In the package manager, click the foldout arrow next to “Input System” and click on “See other versions” 1.3.0 should me in the extended list of versions.

That button is absent in 2021.3.8f1. Apparently they did this to “ensure stability” or some crap. What is happening to Unity? I haven’t had this many problems in ten years.

Damn, that’s strange, I’m on 2020.3. Guess I won’t be updating to 2021 any time soon if that’s true

10

Completely nonsensical thought process for this change (imo) ESPECIALLY with this Input System 1.4.1/1.4.2 regression fiasco. I hope they revert this decision.

Ah ha! I edited manifest.json and changed “com.unity.inputsystem”: “1.4.2” to “com.unity.inputsystem”: “1.3.0”.

It works flawlessly now.

my character moves alone with imput system 1.4.2 if you use the keyboard it seems that when I release the WASD or arrow keys don’t execute the cancel phase

15

Check the latest update thread for the Input System a lot of other people are saying the same thing

16

Thanks
