3 bug in Chrome/Canary/Firefox

Unity Engine
1

Hello,

I have already made a topic few months ago for a mouse and cursor lock problem in Chrome/Canary/Firefox and only one of them has been fixed by the web browser vendors.

Like the Web Player deadline is started on Firefox, i really want to see these issues fixed for the webGL because for my FPS, these problems are important.

Bug 1 :
In google chrome or canary, press tab to lock the cursor and use your mouse scroll without moving your mouse and after move your mouse a bit, you can see that the camera rotation change.
Everything work when the cursor is not locked. Everything is fine in firefox.

Bug 2 :
In google Canary ,if you use the mouse scroll foward or backward when the cursor is locked, you only get negative value. Work well when the cursor is not locked.
Everything is actually fine in Google Chrome and firefox.
Press TAB to lock the cursor and use your mouse scroll and see the Scroll Val below.

Bug 3 :
In firefox , when you unlock the cursor (Cursor.lockState = CursorLockMode.None; and Cursor.visible = true;), the camera rotate on the left if your cursor was on the left side before the lock (same for the right,up down).
Bug not present in google chrome/canary.
Move your cursor on the left or right and play with your tab button to test.

Tested on :

Google chrome 56.0.2924.87
Google Canary 59.0.3033.0
Firefox 51.0.1

I could repro number 2 (but the reverse, can only get positive values in locked cursor mode.
Filed a bug with us but will probably be a Chrome thing for Google to fix.

Will try to look at the rest later again. Ideally you’d file them as individual bug reports and ping case numbers here.

Can’t repro the other two. Can you make a short video or gif and attach it to your bug report?

I don’t know if the unity staff have a direct contact with the google team and like i don’t have seen any new bug report on the Chromium bug report these days,I have open 2 case myself :

Hello,

Can you move foward with google with the bug 1 : https://bugs.chromium.org/p/chromium/issues/detail?id=701970 because 5 months after, it’s still the same and it’s a big problem for an fps game.

Thank you.

Yet no update from google’s side even after months, could someone from unity technologies bump them up.

13

+1 , it’s not unity fault but it’s really bad for an fps game…

14

@Marco-Trivellato Possible for unity technologies to bump Google for this weird issue ?

15

We will bring this up in our next sync-up with Google.

For the bug 1, i’m not sure that the bug come from chrome at 100%, after an answer from the google team,i have tested a webgl game not build with unity and it do not have the mouse scroll problem ==> Emscripten-Generated Code

(click escape => remove bot when the bot shot you (annoying for test))

@roka are you able to repro on Mac? or, is this Windows-specific?

It appears Firefox sends a mouse move event on cursor unlock for some reason. We are going to workaround it.
