Disabling & Enabling Scripts

[Fenwick]

Hi, I was wondering if someone can help me on this problem I'm having....

I have a script, that displays the Enemy's HP/SP.

I am turning the script On and Off like so:

1 - Player uses an Item in battle
2 - Item triggers a "Common Event"
3 - "Common Event" turns On Switch ie: Enemy_Stats_Enabled = 51

Problem:

When I use the item during battle, the script is off (which is right), it turns on the switch (using the item in battle) to enable the script, but I get an error message on line #109 the error line is:

@enemy_hpsp_window.visible = @battler_visible

Error Message: Script 'Enemy HP/SP' line 109: NoMethodError occurred.
undefined method 'visible=' for nil:NilClass

Is there any way I can fix this? Or is there some other way of Enabling / Disabling this script while during battle so I don't get errored out?


Any help is greatful

Thanks again.

And Yes, I would like to turn on and off the Script (Script 1 Enemy HP/SP) via a Switch.

Sorry about posting the scripts this way, not sure how to make the Script Content Hidden in a button.

 

[Opt7ons]

Well, do you have a copy of the script we can see?

 

[Abbey]

Do you want it to be controlled by a switch?
If you do, just put them in a new script in this format:

If $game_switches[[i]Switch Number[/i]] == 0
[i]Script 1[/i]
else
[i]Script 2[/i]
end

Put it just above Main, like almost every other script. I obviously haven't tested, but I don't see why it wouldn't work...Okay, so I do, but I don't have the scripts, so I can't test it.

EDIT: Ignore me, I wasn't thinking
