[rmxp] pk8's self variable script and parallel process

[Karltheking4]

pk8's self variable script (below) is a really awesome script, but I can't figure out what this odd problem is.
It won't work in parallel process map events, if you try to script it, it gives you an error on line 127. about not understand '[]''s

Any ideas???

PLease help!!!

pks self variable script: ShowHide

║ ■ Author's Notes ║
║ Lowell/Adalwulf mentioned creating a "Personal Variables" system which filled║
║ my head in with ideas about variables and switches. One of these ideas being ║
║ self variables. ║
╟──────────────────────────────────────────────────────────────────────────────╢ ​​
║ ■ Introduction & Description ║
║ This script is pretty similar to that of the built in feature: Self Switches.║
║ For those not familiar with Self Switches, Self Switches pretty much pertain ║
║ to a specific event. Example: Treasure Chests. ║
║ ║
║ Self Variables allows users to set certain variables pertaining to a specific║
║ event. Examples include: An event's feelings towards you. ║
╟──────────────────────────────────────────────────────────────────────────────╢ ​​
║ ■ Features ║
║ ─ Set self variables of an event via call script. (How to use is below) ║
║ ─ Get self variables of an event via call script. (How to use is below) ║
╟──────────────────────────────────────────────────────────────────────────────╢ ​
║ ■ How to Use ║
║ ║
║ ● Setting up a self variable: ║
║ To set a self variable for an event, you'll need to call this script on a ║
║ map event: ║
║ self_variable(id, value, oper) ║
║ id: Self Variable Identification. Example: 'feeling' ║
║ value: Give it a value. ║
║ oper: 0: Set, 1: Add, 2: Sub, 3: Mul, 4: Div, 5: Mod ║
║ ║
║ ● Getting a self variable: ║
║ To get a self variable for an event, you can call this script. ║
║ self_variable(id) ║
║ id: Self Variable Identification. ║
║ ║
║ ● Using self variables in evented if conditions. ║
║ You're probably wondering how, right? Alright. To do this, go to the ║
║ conditional branch event command, click on the fourth tab, select Script ║
║ and type either of these in the input form: ║
║ self_variable(id) == value <- Equal to. ║
║ self_variable(id) >= value <- Greater than or Equal to. ║
║ self_variable(id) <= value <- Less than or Equal to. ║
║ self_variable(id) > value <- Greater than. ║
║ self_variable(id) < value <- Less than. ║
║ self_variable(id) != value <- Not Equal to. ║

║ ■ Thanks ║
║ Lowell: He mentioned creating a personal variables system for his project ║
║ (I think), which made me catch "the scripting bug". ║
║ Decibel: Wanted some way to get self variables into messages but I couldn't ║
║ do it. Someone, help! ║
║ Kain Nobel: He helped me with making this an RMXP script. ║

Make sure you are starting a new game rather than loading a previously saved game from when you didn't have the script yet.

Also, in future put your code in spoiler tags. Otherwise it can get broken.

[Karltheking4]

Creating an entirely new project with just that script, 1 parallel process map event with

self_variable(1, 1, 0)
print self_variable(1)

gives you the same error!!!

The odd thing is though, it works fine if it's an autorun event, but unfortunetly, that's not needed!!!

also, woops! sorry!

Are you sure that you are using the right key here? Self Switches used the map ID, the event ID and the switch's letter so I would assume that self variables should work the same way.

[Karltheking4]

║ To set a self variable for an event, you'll need to call this script on a ║
║ map event: ║
║ self_variable(id, value, oper)

?!?!?!?!?!?!?!

Nevermind, I just took a look at the code, it's doing that stuff automatically.

So... any ideas
