Variable issues

This is kinda a repeat topic, since it goes over something I already have a topic on. However, this is an issue entirely of it’s own. I’m attempting to make a combat system using a methos suggested be StephenHart in my other topic.

I posted this error in there, but I figured I might get a quicker response making a newer topic instead of waiting for someone to stumble on that one.

This is the error.

It’s because choice script hates negative values. You can work around this limitation to use negative values, but I suggest you don’t as it will cause more issues along the way.

What I usually do to represent negative values is shift the 0 to another location. For example, 50 for neutral (zero). 0-49 negatives and 51-100 positives.


Thanks! With 50 as the neutral value, I can make it work.

Yeah, you can do *create neg_value "-5" (or *create neg_value 0-5) if I remember correctly, and it’ll “work”. But it’s semantically horrifying, so the above solution is probably better, where it works.


Honestly, I didn’t realize I was setting it to a negative value. I was attempting to set it to subtract 5 from the standard agility variable of 15. So instead of changing agility from 15 to 10, I was changing it from 15 to -5.

Apologies. I should have tested the code before I posted it :anguished:

As others have said, initialisation has to be a non-negative number, just that some numbers have to be more positive than others.

Another trick I have found is to use startup.txt to simply declare the variables with value 0. I then have an init function to set the values, in which *set foo - 5 will work.

It does involve double-handling which is a downside although even that can be useful in obscure circumstances where you want to compare the effects of two sets of values via two different init functions.
