 [Unsupported] PK8's Self Variables XP
#1
PK8's Self Variables XP
Version: 1

Introduction
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.
  • Get self variables of an event via call script.

Screenshots
How can I screenshot this?

Demo
No demo.

Script
Code:

? ? 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.                          ?
????????????????????????????????????????????????????????????????????????????????
? ? This aliases the following...                                              ?
? command_new_game           - Scene_Title                                     ?
? write_save_data            - Scene_Save < Scene_File                         ?
? read_save_data             - Scene_Load < Scene_File                         ?

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.

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.

Terms and Conditions
Possibly an RMVXP exclusive.

not out of the woods yet. I made an event to set a self variable and then check if its 5 in another page.
Whatever I named it it says "uninitialized constant" for that name.
