Bug saving/loading global integer variables

[JMC002 Neil]

Apologies if this has already been reported - I looked but couldn't find any reference to it.

I spent a while looking for what I though was an elusive bug in my code. I finally realised that there is a weird little bug that occurs when global integer variables are saved then loaded (in saved games). If the value of the variable is -1 when a game is saved, it is 1 (not minus) when that game is later loaded! Other negative values are saved and restored correctly, as far as I can see. Only global integer variables with the value -1 are affected!

I'm using version 4.51 of Adventure Maker (full version) on Windows XP.

I wonder if someone else could try saving / loading a global integer variable with a value of -1, to see if it happens to them?

Yes, I have just tested it and you are perfectly right. This is definitely a bug.

Thanks for reporting it. It will be fixed asap.

I didn't know that...

Does it do the same with variants?

I haven't tried it with Variant variables. I'd guess it'd be the same but I'll try it and see....

....actually, the "-1" is saved and loaded correctly in a Variant variable (I just tried it). Possibly because it is stored as a string rather than a numerical value.

Then you could save it in a variant before exiting the game and load the value from it using th ConvertToNumber Function...

True. I avoided the issue by simply not using the value -1! Still a bug though, and worth reporting.

The bug should be fixed in AM 4.5.2.

Thanks.

Thanks.

Cool! (again)

Indeed; just tried saving a Global Integer Variable at -1 and it was still -1 when the game was reloaded.

Actually... I'll be blunt. A variant variable isn't strictly a string.

In this example the variant variable is of SUBTYPE Long, which is a type of integer.

It's a common misconception people have, I'd just thought I'd mention it here...

Fair enough. Clearly, it was either handled or saved differently to "Integer" variables, because one was saved / restored correctly, and the other was not.

It's fixed now, anyway.
