On Screen Typing [LUA]

[ilovekittens]

This is my first modding related post in many years, but I'm very excited to show you guys this on-screen-typing system (or whatever you wanna call it)

It's not as good as being able to just type with your keyboard, but it's probably the best way to go about this completely in LUA script modding without creating any scripthooks or anything fancy like that.

Code: [Select]

--[[
--control scheme--
dpad up/down: scroll through letters
left/right weapon wheel: change case
dpad left: backspace
dpad right: next character
grapple: insert an underscore (_)
sprint: confirm text
]]

function main()
Wait(1000)
while true do
if IsButtonBeingPressed(3, 0) and not gTyping then
typing_typedStuff = F_OnScreenTyping("text: ") -- no args are necessary here, but you can optionally put a string of text here to display before the typing string
TextPrintString("typing finished", 2, 1)
elseif IsButtonBeingPressed(1, 0) and not gTyping and typing_typedStuff ~= nil then
TextPrintString("You typed: "..typing_typedStuff, 4, 1)
end
Wait(0)
end
end

end
end

I commented just about everything I felt needed explaining. This example script isn't really intended to be run alone, but my intention of this post for you to be able to use the functions in it in your own script mods if you know what you're doing.
When you call the F_OnScreenTyping function, you should set a variable to be equal to it like I did in the script.

Code: [Select]

typedStuff = F_OnScreenTyping()After this line, typedStuff will hold a string of whatever you typed.

You can add more characters to the "typing_chars" table, as many as you want. I didn't include any characters other than numbers and letters because I originally scripted this system to type out file names to save bike races and spawned objects to in my trainer.

If you have any questions, leave a reply.
