(Bug) HAT [Henry's Animation Tool] has client-side loading issues

[Zeldaboy14]

So recently, i decided to test a 2012 garry's mod animation helper, and it seems like experiement can't run it. Console printed this. Serverside code is fine by the looks:

Loading HAT Core...

[Lua] error loading file 'hat/cl_hat.lua': ...ent-source\game\experiment\addons\hat\lua\hat\cl_hat.lua:17: attempt to index a nil value (local 'vgui')

Yo! I'm excited to see someone try this, thanks for that.

Now before I get going, let me be clear: This mod is in no way ready for use. If you dive into it, beware that a lot may be broken.

That said, I can only work with what you give me, which is the error stack, so:

Looking at the error stack trace:

1. gmod_compatibility/sh_init.lua:2138 is this line:
   

   experiment-source/game/experiment/addons/gmod_compatibility/scripts/lua/includes/modules/gmod_compatibility/sh_init.lua

   Line 2138 in 1e8b40d

   includeFolder("lua/autorun")

2. the next line (2052) is just the loading of all files in that folder.
3. The is about vgui being a nil value, meaning it doesn't exist
4. However in hour gmod_compatibility/sh_init.lua file it is defined at the top:
   

   experiment-source/game/experiment/addons/gmod_compatibility/scripts/lua/includes/modules/gmod_compatibility/sh_init.lua

   Line 237 in 1e8b40d

   vgui = Panels

5. Last time I tested the Panels (and thus vgui) library it worked, however it may have broken.
6. I'm interested to see the code, at least the hat\lua\autorun\hat_init.lua and hat\lua\hat\cl_hat.lua files, I suspect the problem is in there

My assumption (which you could confirm):

• The hat addon includes a cl_hat file, but because it's in lua/autorun that is run shared (so on the server too). On the server, Panels (and thus vgui) don't exist
• The fact that it's loaded on the SERVER (while it should load on the CLIENT) is further supported by the beginning of the stack trace: gmod_minimal\gamemode\init.lua:1
• That or: Something with the CLIENT / SERVER variables is broken in Experiment

Something also confusing to me: your error says attempt to index a nil value (local 'vgui'), notice 'local'. If vgui was trying to be accessed and it didn't exist, it should say global 'vgui' normally. Perhaps the vgui variable is incorrectly being set somewhere in the code? That or the hat addon has local vgui = vgui at the top, which should work fine, since vgui on the CLIENT would point to Panels, which should have the expected functions

Hope it helps

So i reverted, as i forgot i had made some changes. The issue intially was that the client code never seems to initiate at all, so i was trying to force-load it thru the autorun code. Server-side code initiates fine (am seeing that in console still), but something is wrong on client-side. I'll give you the extracted addon to see if you can't see why the client code never initiates

Thanks for sharing the addon, that helps.

There were some missing compatibility functions that prevented that addon from fully loading. I've pushed some changes to ensure it at least loads.

However: From my limited testing I can tell the addon doesn't work in Experiment Source. This project really needs a lot of work, before you can expect any addon to work with it and it's not one of my projects that has my attention atm. So if you want to get it to work, you're on your own from here.

Good luck!
