Is there a method of saving an unsigned int to a file using ConfigFile?

I noticed when I saved a large seed number generated by randi() to a config file using ConfigFile, the number saved was different. I tried a few numbers until I realized it was saving the unsigned integer as a signed integer.


If I check the file, it shows the number as negative since bit 32 is set.


When I read the file back and print the contents I get the same negative value instead of the positive value I started with.

print(config.get_value("Config", "test_value32"))

Output is:


To get around this, I could switch to using File instead of ConfigFile and save the data in a json format. That seemed to work correctly when I did a quick test. Another option I thought of was that I could possibly create a function to convert the signed 32 bit integer into an unsigned integer when reading back.

what version of godot are you using?

I’m using Godot 3.0.6

there’s no uint for gdscript.
but godot supports 64 bit integer.
I’m not sure 3.0.x too.
would you try it with 3.1.beta?

Same behavior with 3.1 beta

var test = 2147483649
print(test)  # this prints correctly 2147483649

so I guess it’s a kind of bug.
you need to report it on github issues.
