[RMXP] PERMANENT BUTTON CONFIG?

I was just testing my game from someone else's computer and I had to go into config to set up the V key as the R button. Normally in XP the R button is assigned to W only. But my game has it as both W and V because I feel that V is a more comfortable position for it. I can't assign it to other buttons because those are needed for other functions. When you play my game it tells you that you can slide with V or W. So it'd be terrible if players have to manually press F1 to config what I intended as default. Do any of you know how to make sure that my config for the V key stays with the game no matter who's computer it goes to? Is there something in the script I can alter?

Shit. Well I really want people to have the option of using the V key it's more comfortable than reaching for the W key. Should I just have a message near the start of the game telling people how to customize it that way? Or should said message pop up when the player first learns how to slide?
It just feels wrong. People are going to find it odd that I as the creator am suggesting a button config to them rather than providing it.

Does anyone have any suggestions?

I'm trying it right now but my scripting skills aren't that good.

So what I tried to do was I took that first script labeled Module and inserted that in. Next, I inserted that second script labeled Methods separately. Is that correct so far or were they supposed to be in the same insert?

After that I setup a call script in an event and typed:
find Input.trigger?(Input::R)
replace (Keyboard.trigger(Keys::V)

That got a syntax error.
So clearly I don't know how to do it. If you can give me a little more help, I'll try again. I appreciate the help LockeZ thanks.

If it's too much to teach than I suppose I can just tell the player about customizing controls but I would like to give this script another try.

Edit: Oh by find/replace do you mean using the control F to locate a line and replace the line of code? Which script would I search in then because the new script didn't seem to have that line? Well I guess I could just try to search all my scripts.

Edit: Also is there something in the Module or Method that I need to edit?

The way R button is used in my game is in two Common Events that are on through most of the game. They are fairly long events but basically I'll try to give a sort of summary example of the way they involve the R button:

Conditional Branch: The R button is being pressed
Conditional Branch: The player is facing down
Set Move route Player
Graphic "Lanoa Ducking"
Wait for moves completion
Control Switches 0598Duck is ON

Another Example is:

Conditional Branch: The Down button is being pressed
Conditional Branch: The R button is being pressed
Control Switches 0597Sliding is ON
Play SE 'swing'
Set Move route Player
Graphic "Lanoa Sliding"
Change Speed 5
Move Down
Move Down
Change Speed 4
Wait 1

So do I just need to put something into those Common Events?

So I followed your instructions and this is what's happening so far; I got an error screen saying:

Script 'Custom controls Methods' line 130: NoMethodError occurred.
undefined method `include?' for nil:NilClass

The line in question reads the following:

return @used_i.include?(key)

I'm going offline soon because it's night time in my time zone but I'll try again tomorrow. Thanks for your help so far LockeZ.
I copied and pasted the line that you gave me so that should be fine so maybe line 130 needs to change. What do you think?

There is good news and bad news.

Good news is nothing is crashing, the script now works.

The bad news is that the script doesn't seem like it was made with button holding in mind. It only seems to notice pressing of a button.
Noramly in my game if you hold down either the W or V key Lanoa will duck down and from there you can choose to slide in a direction.
But now holding the W key is like pressing it once because she ducks for a split second then stands up. As for the V key, holding that down has Lanoa flicker back and forth between ducking and standing.
Because in my game, to stop ducking is as simple as letting go of the button but since the script handles things as presses it doesn't work.

So is there a way to make it understand holding the button?

If not I suppose I'll just have to explain customization to the player?

Another option I just tried was to make a different button for standing back up but that's rather awkward. For example say you are playing Megaman or Street Fighter, you duck by holding the down button and get back up by releasing it. It'd be weird if you had to press a separate button to get back up.

Edit: Well regardless, it was still worth a try I apprieciate your help LockeZ. I believe this is the second time you helped me with a script. The last time it worked. This time it might not but either way I thank you for your time.
