Kernel Panic 4.4

[gatopeich]

Hi, I am trying to run KP 4.4 with Spring 87 on Linux (spring from Ubuntu PPA).

The game loads but just does not start after the 3,2,1 countdown. It just says something like "AI taking over..." and the units/bases just don't spawn.

Thanks for the bug report.

- A change in the engine resulted in WeaponDefs entries somehow losing their pairs method.
- This broke one of KP gadget (specialattack.lua line 35)
- This failure somehow brought down every following gadget.
- The gadget responsible for spawning start units is thus absent.
- Nobody gets any start unit!

I will probably have to release a version 4.5 of Kernel Panic. Might take me between a week and a month.

Meanwhile, I hope you can downgrade your Spring to version 85.0.

WeaponDefs entries somehow losing their pairs method.

not sure if is that. When you add an echo:

Code: Select all

for id,weaponDef in pairs(WeaponDefs) do
   for name,param in weaponDef:pairs() do
		Spring.Echo (name)
   end
end

it goes like:

Code: Select all

[f=0000000] accuracy
[f=0000000] false
[f=0000000] Error in Initialize(): ERROR_TYPE in WeaponDefs __index

So it loops a bit stuff before failing.
Maybe the WeaponDefs table is somehow corrupted?

FLOZi, your link is inconsistent with your words.

We have had some other threads on Spring forum about how .areaOfEffect, .maxVelocity, .onlyTargetCategories fields have been removed from weapon definitions, and even explanations from developpers on the why.

The dev also decided to make errors caused by trying to use those missing fields less serious, which is what your link is about. It's somehow related to the issue I mentioned above as the error would cascade less.

But we still don't know if the removal of :pairs was intentional or "accidental oversight".

I'm also curious to know why was :pairs added in the first place, why it was removed, ...

[FLOZi]

Removal of fields was intended.

Error on :pairs() is clearly (mind-bogglingly obviously) unintended and has therefore now been rectified (see link).

[zwzsg]

Then I just fail at seeing 'pairs' in your link.

knorke says 'pairs' loops a couple times before the error, which would indicate pairs was not removed, just made wonky.

It fails specifically on those fields which were removed, my interpretation of the commit message is that those fields can now be safely iterated over again.

Does it mean latest KP from git repo will work?

[zwzsg]

Doubtful. I'll try to update this weekend. This fix is small, but I'm afraid there's more.

[gatopeich]

Just built Spring from git sources, version 87.0.1-54-g5df3e5b.
Now KP gets stuck at "Choose Start Position", no matter what the configuration is.

Will try rolling spring back to 85...

[zwzsg]

The bad new is that I haven't released a 4.5 yet.

The good new is that the missing weapon def field crash was made less severe in Spring 88, so Kernel Panic 4.4 works again in Spring 88.

[Neddie]

Anything else that might make it into 4.5?

Waffle: a new unit that can only be defeated by either eating it or attacking it's top with syrup.

Anything else that might make it into 4.5?

The only changes I've gathered so far are:
- Removed the debug code in specialattack.lua that caused issue to Spring 87
- Update the flows speed often, as an attempt to override max speed change getting reset
- Changed carrier animation script to detect cancel differently

But I'm not even sure they're worth making a 4.5, considering the speed change still isn't properly fixed, and that Spring 88 prints errors but don't crash on the for name,param in weaponDef:pairs()

I doubt this'll get read any time soon, but theres a major bug with kernel panic.

It doesn't run! I can get it as far as the menus, with the units battling in the background, but once I try to run the game, it quits to the desktop. no popup message no nothing! I use windows 7 btw.

(try to) play a game of KP, then post the infolog.txt file

[Dotz]

here it is. before you ask, I've tried installing it as a separate game with its own version of spring, but that didn't work either.

[Dotz]

um... is someone gonna reply?

Code: Select all

[f=0000000] Error: LuaUI::RunCallIn: error = 2, DrawScreenEffects, [string "LuaUI/widgets.lua"]:1292: attempt to index local 'w' (a nil value)
[f=0000000] User exited

did you disable lua ui in your spring settings maybe?
