No more money-making?

[Rene25]

Hi there,

I'm a big fan of TTD, play is since the beginning ('96?). But one thing is bothering me very much. And that is, when you make an awful lot of money, it counts to 4.294.9xx.xxx (so somewhere around 4.2 billion dollars). You see your trains, ships, airplanes and cars making money, you see the deliverd cargo at a stable rate (66.000 a quarter), but, you cannot make more then those 4.2 billion dollars in total. This was a problem with the first release, TTD for DOS, but also with TTD and the Patch, running it on XP.
Can someone give me a solution for this annoying problem? It's possible for me to send you my save-game, then you can see it for yourself.

Thanks anyway!

$4.294.967.296?

Sorry mate, thats because the value that holds the current amount of cash is a 32bit value (Maybe 64bit to take into account negative money, my guess is that its a 32bit register or two 16bit registers squished together holding the value, but thats just my guess ), which ends up being 2^32, or 4294967296.

hmm, well, i thought something like that. Thanks anyway!
So, this is not a solvable problem? Not even for someone makes programs like the TTD Patch? Maybe something for the future...

I never had that much cash...

I always played for seeing my trains

Well, you can try "Cht: Money 0"

EDIT: Or fund some new buildings

The money is stored in a 32-bit variable - remember, TTD uses pounds internally, so the range is -£2,147,483,648 to £2,147,483,648 or so, doubled for dollars, etc.

Oke..... well, that figures that, why you set the currency to "Yen", it's possible to have 429 billion...
I hope some smart guy can solve this problem, because I'm done playing when i can't make any more money....

Thanks for the explanation though!

some smart guy would make it a 64 bit game, but thats like impossible.

[orudge]

OpenTTD uses 64-bit variables for the money now (and indeed you can compile the entire program as 64-bit if you have a 64-bit processor), but it's likely one of the Really Impossible™ things for TTD/TTDPatch.

[DeletedUser21]

something is impossible only until someone does it.

This isn't really all that difficult, since the money variable is only accessed through a few functions. Still it's more work than it's worth...
