Question About ZDoom Console

[Summer Deep]

I'm playing the '1000 Lines 2' megawad in ZDoom, UV continuous format. All was fine until the end of MAP06, when the game repeatedly crashed before it could autosave. Thus I could only start MAP07 with an idclev pistol start.

 

A reasonable solution seemed to be to use the ZDoom Console's commands to restore my health and ammo to what it had been at the end of the previous map. This went fine, except that I could find no way of reinstating my rockets. The commands 'give rocket', 'give rockets', 'give rckt' and 'give rckts' all were rejected as invalid. Could anyone please suggest the correct form to use here?

 

A it turned out, this wasn't such a big deal, as plenty of boxes of rockets turned up near the start of the level.

 

Any suggestions also as to why the game may have crashed? MAP06 marks the end of the first episode in this wad, so I'm wondering whether there was some kind of death exit that ZDoom couldn't handle? I'm also wondering whether crashes in this sourceport will become more common with new wads, as ZDoom is no longer being developed.

ZZDoom doesn't crash, it's not a death exit. Those maps were developed for a recent GZDoom version.

About the console i think they are rocketammo and rocketbox.

Wiki says it was developed for Vanilla, not specifically GZDoom.

Interesting but there's some specific support for GZDoom as i get some errors in the console.

Well it contains a zmapinfo lump apparently.

 

EDIT: Some errors about Author and compat_explode2.  Seems ZDoom doesn't have these in its definitions while GZDoom does (no issues at all)

Thanks for that - 'Rocketbox' proved to be a serviceable command, though interestingly 'give rocketbox 10' simply gives the player 10 rockets, not 10 boxes of rockets.

 

The other stuff all sounds very interesting, but I'm afraid it's gone a bit over my head....

[Gibbon]

The correct way would be to put give rocketbox this gives you a box of rockets (5 rockets).  Adding an integer (a number) will give you that amount of rocket ammo.

Savegames are not compatible with 2.8.1 though.

[Summer Deep]

I've just downloaded the 64-bit and 32-bit versions of ZZDoom, and will be trying them out in the near future!

[Summer Deep]

ZDoom also crashed at the end of MAP11 in this wad. Funnily enough that does have a death exit.

[Gibbon]

RZDoom also crashes at the exact same point.

Must be something fixed later. But does it crash only on windows or everywhere?

Everything.

 

Here is a backtrace from macOS on a full debugging session.  WE should probably fix it.  I'll get started.

Like i said it was fixed and luckily it doesn't crash in LE. 2.8.1 was a solid release but there were many bugs like in any other release. I applied hundreds of fixes but unfortunately that added other bugs, a 2.8.2 release would have been possible but i thought it wasn't worth (so i didn't propose it). Besides LE was very messy at first.

Try "- fixed: DIntermissionScreen::Init did not handle non-existent strings in the string table and crashed on a NULL pointer." by Graf, that must be it.

[Gibbon]

Good stuff!  I'll steal it then  ;)

[drfrag]

It's not stealing xD , you could cherry-pick it from the ZDoom repo. Besides there wasn't a conflict with that one.

Yeah, I love how it is really simple.  A nice clean fix that makes sense.
