I'm having trouble putting calls into a multi-dimensional array. Does anyone know a solution to turn a string to a call, or something else that could resolve this problem?

Just be careful with eval. It's a very consuming method and you should avoid by all means to place it on a method updated every frame.

I'm not sure what the question is.

Why do you want to evaluate a string as a method call?

Code:

def test
   p 'hello'
end

def another
   p 'another hello'
end

arr = [method(:another), method(:test)]
arr[0].call
arr[1].call

arr.each {|m| m.call}

I guess I'll post it here. I have it designed out completely, but I ran into a problem. I plan on sharing it anyway, so it won't hurt anything.

It is not finished yet. I'm trying to get the scripts for variables working. I originally made it only to patch YEA - System Options which I had working, but I wanted to take it to the next level and allow all switches/variables to be used to call scripts. The options menu was going to do it for you automatically, but other things would require you to do an event script call. I can do all of that easy though.

# You need to add each switch/variable you want and what it will call in the

# when they meet the requirements, where variables will always call and embed
# that value into the script call. For example, if you have a argument in your
# script call it will place the variable in the argument. This does not have
# support for multiple arguments, so you can't have a script call that has more
# than one.

end

module OptionsHelper
OptsIndex = {
3 => :set_windowskin
}
module_function
def set_windowskin(idx)
$game_system.windowskin = ('Window' + idx.to_s)
end
def callfunc(idx, *args)
send(OptsIndex[idx], *args)
end

$imported = {} unless $imported

if $imported["YEA-SystemOptions"]
class Window_SystemOptions < Window_Command

alias change_custom_variables_al change_custom_variables
def change_custom_variables(direction)
change_custom_variables_al(direction)
variable_script(SCRIPT_CALLS::WINDOW_VARIABLE)
end

def variable_script(cmd_id, *args)
OptionsHelper.callfunc(cmd_id, *args)
end
end
end

You can do something like this.

And we need Ruby BBCode....

eval is evil and almost never necessary. Unless you are creating an interactive interpreter prefer function objects.

This is the fixed version.

Does anyone know of a way to check variables/switches changing? If not do I need to make my own function to do this?

Look at Game_Switches and Game_Variables classes and how they are setting the values.

It is already telling the map to refresh, so you just need to add to it.
