Arrays + Calls

[Helladen]

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?

turn a string to a call

eval

Thanks.

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?

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 I originally made it only to patch YEA - System Options which I had working, but I wanted to take it to the next level and allow all switches/variables to be used to call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.

# It will automatically call the script for you if you change them in

#
# You need to add each switch/variable you want and what it will call in the
# configuration below. Switches work differently than variables, they only call
# 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.

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.

 

[Helladen]

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.

Thanks.
