So, in the custom story that I'm creating, I name things I need to interact with in the code quite precisely. Usually it takes the form of: ROOMNAME_ITEMNAME_TYPE

So for example, a note might be labled: lab_chemDiscovery_note

I wanted an easy function to extract the middle word, in the above case this would be "chemDiscovery". However, whenever the function is called, the game just locks up. Can anyone see what I might be doing wrong?


I'm thinking I should be able to call this function as:
or even through passing a callback variable to it (the intention).

If i'm interpreting everything correctly, l would never be greater than 2.

Correct, the goal is to stop the while loop after 2 underscores in the string are found, then return the string value.

Infinite loops halt the game. The only time the script increments l is when it finds an underscore and if the previous if statement evaluates to false. With a syntax of ROOMNAME_ITEMNAME_TYPE, it is unlikely that either if statement would evaluate to true.

I kind of figured that's whats happening but I don't understand is why neither would evaluate to true. It would advance the character number regardless if the conditionals evaluated, until it hits an underscore. Then it would increase l by one and every letter after that would be appended to newString until it hits the last underscore. Thats the intention anyways, did I miss something?

I did a test run, and i got the following output with "Text_Text_Text":


It is on an infinite loop, and as you can see letter never equals "_", so the issue is in the incrementing chr variable. Instead of adding 1, just put simply 1 -- that is, for StringSub.

I'm going to go to sleep now.

Man, I was never able to get the debug messages, my game just froze up...Thanks for your help. I completely forgot that the last argument in StringSub was the number of characters to read and not another character position. Ah well, just had one of those derp moments I suppose.
