Hello RPG Maker forums,

I have a script request on how to check if my switch is true or not.  You would think that I would've easily found this, but not so, I can't seem to make it work.  Here's what I have so far, but it obviously won't work...

Spoiler

if $game_switches[1]
DEFAULT_BATTLE_SYSTEM = :yctb
else
DEFAULT_BATTLE_SYSTEM = :yctb
end

Basically, if Switch 1 is On, I want the default battle system to be set to :yctb and if it's off, I want it set to :dtb.  I'm sure it's really simple, but there's just something I'm missing.  I want it all done via scripting, don't want any event calls or anything.

Thanks for any and all help,
James

That first line should be:

if $game_switches[1] == true

Yet another derp moment.

You can also shorten that to

if $game_switches[1]

or, for false,

if !$game_switches[1]

Sorry I wasn't more specific on the problem. This is the error I get if I do what I posted above:

Spoiler

Script 'Ace Battle Engine' line 245: NoMethodError occurred.
undefined method '[]' for nil:NilClass

This is the page to the original script I used.

And here's the script...

It # allows for easier management of the battle engine without adding too many # features, allowing users to customize what they want as they see fit. While # the Ace Battle Engine isn't an entirely new engine, it gives users control # that RPG Maker VX Ace didn't originally give them. # # Furthermore, this script provides some new features. They are as follows: # # ----------------------------------------------------------------------------- # Animation Fixes # ----------------------------------------------------------------------------- # Though the Yanfly Engine Ace - Ace Core Engine script contains these fixes, # these fixes are included in this script as well to ensure it's working for # the battle script in the event someone chooses not to work with the Ace Core # Engine script. The animation fixes prevent excessive animation overlaying # (and making the screen look really ugly) and prevents animation clashing # between two dual wielding normal attack animations. # # ----------------------------------------------------------------------------- # Enemy Animations # ----------------------------------------------------------------------------- # Enemies now show battle animations when they deliver attacks and skills # against the player's party. Before in RPG Maker VX Ace, it was nothing more # than just sound effects and the screen shaking. Now, animations play where # the status window is and relative to the position of each party member. # # ----------------------------------------------------------------------------- # Left/Right Command Selection # ----------------------------------------------------------------------------- # While choosing actions, the player can press Left or Right to move freely # between (alive) actors to change their skills. Players no longer have to # cancel all the way back to change one person's skill and reselect everything. # On that note, there is now the option that when a battle starts or at the # end of a turn, players will start immediately at command selection rather # than needing to select "Fight" in the Party Command Window. # # ----------------------------------------------------------------------------- # Popups # ----------------------------------------------------------------------------- # Dealing damage, inflicting states, adding buffs, landing critical hits, # striking weaknesses, missing attacks, you name it, there's probably a popup # for it. Popups deliver information to the player in a quick or orderly # fashion without requiring the player to read lines of text. # # ----------------------------------------------------------------------------- # Targeting Window # ----------------------------------------------------------------------------- # When targeting enemies, the window is no longer displayed. Instead, the # targeted enemies are highlighted and their names are shown at the top of the # screen in a help window. Another thing that's changed is when skills that # target multiple targets are selected, there is a confirmation step that the # player must take before continuing. In this confirmation step, all of the # multiple targets are selected and in the help window would display the scope # of the skill (such as "All Foes" or "Random Foes"). RPG Maker VX Ace skipped # this step by default. # # ----------------------------------------------------------------------------- # Toggling On and Off Special Effects and Text # ----------------------------------------------------------------------------- # Not everybody likes having the screen shake or the enemies blink when they # take damage. These effects can now be toggled on and off. Certain text can # also be toggled on and off from appearing. A lot of the displayed text has # been rendered redundant through the use of popups. # # ----------------------------------------------------------------------------- # Visual Battle Status Window # ----------------------------------------------------------------------------- # Rather than just having rows of names with HP and MP bars next to them, the # Battle Status Window now displays actors' faces and their gauges aligned at # the bottom. More status effects can be shown in addition to showing more # members on screen at once. The Battle Status Window is also optimized to # refresh less (thus, removing potential lag from the system). # # ----------------------------------------------------------------------------- # Window Position Changes # ----------------------------------------------------------------------------- # Windows such as the Skill Window and Item Window have been rearranged to # always provide the player a clear view of the battlefield rather than opening # up and covering everything. As such, the window positions are placed at the # bottom of the screen and are repositioned. # #============================================================================== # ▼ Instructions # =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= # To install this script, open up your script editor and copy/paste this script # to an open slot below ▼ Materials/素材 but above ▼ Main.

Sorry, the above code isn't split into lines...

Thanks for any and all help,

EDIT: In the above code, I only showed down to where it says after this line, don't edit.
EDIT2: In the above code, I shortened it so it only shows from the beginning to the line that sets the Default Battle System.
EDIT3: Is there something I have to call, or a class or def I have to initialize or whatever before I get to this line? That might be the problem.

So you want to test the switch in the settings area?
That won't work since it's not inside a method.
You can only set variables/constants out of methods.
You'd have to search for the place where the script asks for the DEFAULT_BATTLE_SYSTEM and decides what to do.
At least that's what I guess before looking at it in detail

[Gadwin]

why dont you just use the default change system code coded by yanfly for example

if $game_switches[1]
$game_system:set_battle_system(:ftb)

else
$game_system:set_battle_system(:dtb)

end

[chessplayerjames]

Sorry, maybe I still wasn't specific enough. I was trying to change the default battle system where it asked for it, but the problem is

if $game_switches[1]

That's the line where the error occurs, and I think it's the

[1]

Don't know what that has to do with it, but that's where the error is thrown.

[chessplayerjames]

Bump. I thought checking for switches should've been really easy? What am I doing wrong? (Look in the above error).

Thanks for any and all help,
James

[Chaos17]

Yeah, in test mode just press F9.
You will see a list of switch and variables.

If you want to use 2 different battle system, I recommend using this script, it will allow you to do it : Multiple Battle Systems
"This script allows you to create multiple battle managers that may have their own unique set of battle logic. Different battle scenes with their own battle windows can be added as well."

$game_switches is only instantiated AFTER you start a game. If you have your initial code somewhere that causes it to be run on launch, $game_switches will not exist.

If you want the player to determine which battle system to use, you will either have to use a global variable that gets set from the main menu, or if you want to use $game_switches, you'll have to check it and set the battle system sometime after the new game is initialized.

The problem is that when you check that item in the array, the array itself doesn't exist in memory yet and that's why Ruby it's telling you that's nil.

You need to do that operation somewhere else, after the code of creating the array (which is in DataManager line 87) has been executed already.
