Javascript error when running in Ubuntu 20.04

[Stéphane Charette]

I upgraded my desktop to Ubuntu 20.04.  Which upgraded 0ad.  But now it wont run.  Instead, it logs this error many times per second:

ERROR: JavaScript error: Errors executing script event "Tick"
ERROR: JavaScript error: __internal(0) Tick line 0
ReferenceError: onTick is not defined
  __eventhandler0 (Tick)@__internal(0) Tick:0:1
ERROR: JavaScript error: Errors executing script event "Tick"
ERROR: JavaScript error: __internal(0) Tick line 0
ReferenceError: onTick is not defined
  __eventhandler0 (Tick)@__internal(0) Tick:0:1
 

I cannot seem to find any references to this error, so could use some help.  This is the version I have installed:

> dpkg -l | grep 0ad
ii  0ad                                           0.0.24~r23742-0ubuntu1~20.04~wfg0          amd64        Real-time strategy game of ancient warfare
ii  0ad-data                                      0.0.24~r23742-0ubuntu1~20.04~wfg0          all          Real-time strategy game of ancient warfare (data files)
ii  0ad-data-common                               0.0.24~r23742-0ubuntu1~20.04~wfg0          all          Real-time strategy game of ancient warfare (common data files)

Hey @Stéphane Charette

Welcome to the forums ! Did you have any mods enabled? This is the dev version you installed, so it's very likely they will be not compatible

[Stéphane Charette]

How do I tell if I have mods?  I ran this command to install it:

sudo apt-get install 0ad

 

[Stéphane Charette]

Oh, you mean in the old version before I upgraded?  Yes, I think I did.  Is there a way to disable them?

Sure see https://trac.wildfiregames.com/wiki/GameDataPaths

should be in ~/.config/0ad there should be a file called named user.cfg

[Stéphane Charette]

Thanks, @Stan`, that helped me solve it.  In case anyone else runs into this:

• Most of the errors were cause by a folder called ~/.local/share/0ad/mods/techtree.
• I found if I completely deleted the folder called ~/.local/share/0ad/mods then it was rebuilt when the game would start up again, and this time with zero javascript errors.

Glad you got it to work! Hope you'll enjoy this new version!
