How would one remove a letter from the string in a table
Example

tHistory = {}
tHistory[1] = ""
h = 1

if key == 14 then tHistory[h] = "" ..tHistory[h].. " " end

i cant see exactly where in your code you would want this but basically just do

tHistory[h] = string.sub(tHistory[h], 1, -2)

Nvm..
For future solutions: string.sub works

tHistory[h] = string.sub(tHistory[h], 1, string.len(tHistory[h]) - 1 )

Want to see my code?

quit()
elseif tHistory[h] == "move" then
-- Move code here
print("Move")
tHistory[h] = ""
else
x = x + 1
tLines[x] = "Invalid Command: ".. tHistory[h]
tHistory[h] = ""
end

Its virtual console.
EDIT: Caps and other grammar things not working yet.

why all of the code? you should just pick it up as normal and then say


if key~="backspace" and key~="enter" then -- and keep doing that to leave out irregular keys
tHistory[h]=""..tHistory[h]..key
end

that way it adds caps and lowercase fine and just leaves out the keys that aren't chars

I tried that earlier (above) it works, but this looks so much cooler. Having thousands of lines of if statements.. lmao.
IDK, It'll show my hard work (IN NPP).
EDIT: It's weird, I have to block key lshift and rshift.
EDIT: Caps don't work.

yeah, you have to block any key that cc recognises as an event that does not enter in a character, there is of course a very simple way to do it, just return the length of 'key' and only add it to tHistory if it is 1 character long…

because anything that is not a typable character has a key description and that is always at least 3 chars long

then you add arrow key, enter and backspace/delete functionality and you have a functioning input receiver

the problem is while you have no doubt put a lot of work into writing all of those if statements the PC now has to put that much effort into reading it every time you press a key, this drastically slows things down
