Common Event Self Variables VX - PK8 - 09-17-2009

Common Event Self Variables VX
Version: 1

Introduction
This script is a 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.

Common Event Self Variables allows developers to set certain variables pertaining to a certain Common Event.

Features
  • Set Common Event's self variables via call script.
  • Get Common Event's self variables via call script.

Screenshots
No screencap.

Demo
No demo.

? ? Setting up a Common Event's self variable:                                 ?
?   To set a self variable for a common event, you'll need to call this script:?
?     ce_self_variable(ceid, id, value, oper)                                  ?
?       ceid: Common Event's ID                                                ?
?       id:   Common Event's Self Variable ID. Example: 'A', 'B'               ?
?       value:  Give it a value.                                               ?
?       oper:   0: Set, 1: Add, 2: Sub, 3: Mul, 4: Div, 5: Mod                 ?
?   Example: ce_self_variable(1, 'A', 5, 0) sets the first Common Event's      ?
?            variable "A" to 5.                                                ?
?                                                                              ?
? ? Getting a Common Event's self variable:                                    ?
?   To get a self variable of a Common Event, you can call this script.        ?
?     ce_self_variable(ceid, id)                                               ?
?       ceid: Common Event's ID                                                ?
?       id:   Common Event's Self Variable ID. Example: 'A', 'B'               ?
?   Example: ce_self_variable(1, 'A') gets Common Event's variable "A".        ?
?                                                                              ?
? ? Using Common Event's self variable in evented if conditions.               ?
?   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:             ?
?       ce_self_variable(ceid, id) == value   <- Equal to.                     ?
?       ce_self_variable(ceid, id) >= value   <- Greater than or Equal to.     ?
?       ce_self_variable(ceid, id) <= value   <- Less than or Equal to.        ?
?       ce_self_variable(ceid, id) > value    <- Greater than.                 ?
?       ce_self_variable(ceid, id) < value    <- Less than.                    ?
?       ce_self_variable(ceid, id) != value   <- Not Equal to.                 ?

Credits and Thanks
Lowell: He mentioned creating a personal variables system for his project which made me catch "the scripting bug".
Kain Nobel: I'm using Kain Nobel's modifications to the Actor & Party's Self Switches script as a base.

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 giving COMMON EVENTS their own self variables.
