Keys

[Rick]

Is there an easy way to get a text value of a key related to the number value of a key or do I need to brute force it manually like:

 

keys["KEY_W"] = KEY_W

keys["KEY_Q"] = KEY_Q

...

 

I'm making a configurable object where the drop down of the setting will list every key in it. I then take the text value they selected and convert it to something that can be used in KeyDown()/KeyHit().

 

I can do this manually, but wasn't sure if there was some looping trick I might be able to do to make the code shorter.

require("scripts/class")

local class=CreateClass(...)

function class:InitDialog(grid)
self.super:InitDialog(grid)
group=grid:AddGroup("Keys")
local letters = "KEY_"..string.char(65)
for i = 66,90 do
	letters = letters..",".."KEY_"..string.char(i)
end
group:AddProperty("KEYS",PROPERTY_CHOICE,letters)
group:Expand(1)		
end

That works for the letters, so I suppose I'll have to manually do all the other keys though? Arrows, Home, Insert, etc

just use all of the equivalent ASCII characters/numbers you wish to use... if there is a break in the numbering then yes you have to take that into account in the for loop... as for the keys that you want like Backspace, Home, etc... just add them all with just one line

 

local class=CreateClass(...)

function class:InitDialog(grid)
       self.super:InitDialog(grid)
       group=grid:AddGroup("Keys")
       local letters = "KEY_UP,KEY_DOWN,KEY_RIGHT,KEY_LEFT,KEY_BACKSPACE"
       for i = 65,90 do
               letters = letters..",".."KEY_"..string.char(i)
       end
       group:AddProperty("KEYS",PROPERTY_CHOICE,letters)
       group:Expand(1)         
end
