Help please: Rebuild Points are Negative

[davf]

My rebuild points for a self-generated campaign are negative (see attached screenshot) preventing me from repairing units and upgrading. This has persisted through two battles and a number of shut downs and restarts. Please help!

(I did a forum search for this and could not find any other mention of it. Sorry if it exists elsewhere already)

Sorry, I don't see a screenshot. Attaching your save files and system information would also help.

[davf]

Sorry about that. I thought I had attached. Here it is.


System is SPMBT version 26th Feb 2011 running on 64 bit Windows 7 Ultimate with Service Pack 1.

I think the save file is just over 6 meg. Is that too large to upload?

Thanks for the help!

Aha... amazing what you can do with zip. Here is the saved game (I hope)

I'm not sure what to do, you'll have to wait for Don and Andy. Thanks for informing them of the bug.

Someone else had this problem with an over-expensive core (he bought loads of artillery, hordes of the stuff, AFAIR).

That causes the integer values to overrun, and so you get negative numbers due to the 2's complement arithmetic digital computers use.

I'll be fixing the code (if it can be) so that cores cannot have > the maximum a defender can have (26000 points) - probably a bit less - as they get more expensive as they gain experience. Or restricting such expensive cores to assault missions, or something.

Meanwhile, simply sell some stuff from your core until the numbers turn positive once more (they should). Use some of that to repair any damaged units you may have left.

Then make sure your core never goes above 20-25K points or so. Otherwise in your defend missions the AI will never be able to match you.

Hmm - I just tried deleting from the sample save game. Apparently the delete option goes when you are in negative points. I'll need to debug that.

This will be a useful save file for debugging huge cores. Especially one with ~20 troops of M109s...

But it looks like that campaign is toast (unless delete core formation works with your version - it may be snafud at my end with the new arty support code).

Hmm - I put the points up to the maximum, and bought a huge amount of challengers for a 64K core. Then bought 10K more at the end of the next battle and so on. Points values all were being handled well - was up to 90K core value soon enough. Points did not roll over to a negative value.

However - a mass deletion of core troops soon made the numbers go funny.. So something is wrong in there - probably old code that has not been updated to a 32 bit value for the points total, likely a 16 bit integer internal to the delete routine - will be investigating that later tomorrow.

So - did you happen to do a mass deletion at some point?

OK - found the culprit that was stuffing a signed 32 bit value into an unsigned 16 bit value and so blowing the delete code up.

Unfortunately, the relevant value is squirrelled away in the save game data as a 16 bit - so its a bit more involved than just changing the variable's type in a function.

I'll need to deal with legacy scenarios and saved games with the obsolete variable (and add new 32 bit ones to the save game files)... data massage tango, here we go!

OK - points problem sorted.

The 64K maximum limit stays though.

It is part of the preferences data and that gets exchanged in a PBEM, and its a bit involved to change that.

In any case - I kludged a 64K defender mission for P1. P2 as FRG in 2013, was allowed the correct huge points total for its assault force - but it could only spend 90K or so in its AI purchase, probably due to the 500 unit limit and/or the 200 formation limit. The AI buys a balanced force, and has no way to cherry pick say a shed-load of 999 point MLRS as a human might to soak up excess points.

Adding to the 1000 unit limit is not going to happen as it nukes all existing saved games, campaigns, scenarios etc, etc..

So the points restrictions stay.

Amazing! I'm sorry for being quiet over the last couple of days... I've been called away for work and am only getting back to a computer now.

In answer to your very old question, there wasn't an initial deletion but I may have gone in to check to see if there was any room for expansion.

The Core button has gone missing on mine also. I have a feeling it may have been present on the previous turn when I first found the issue. I played one more turn thinking maybe that might address the issue for some likely illogical issue.

I know I'm kind of pushing the envelope in terms of 'realism' in the first place, but after playing for so long (since the original Steel Panthers), I mostly just toy around seeing what kind of crazy things I can do. For whatever it's worth, I've played Steel Panthers since the very first incarnation and it's the one game that has outlasted all others on my system... I can't speak highly enough for just how awesome this game is. Thanks for helping keep it that way and keeping it alive!

I can't say enough just how impressed I am with the support and help in this forum, Mobhack (and others). Thanks so much!
