Proper key press proggraming

Hey everyone i just wanted to share a simple way of setting multiple functions related to the same hook; using clean and maintanable code.

example problem: i have a gamemode with multiple menus, one when i press C and another one when i press P.

the first thought that comes to mind is using the function:

function GM:PlayerButtonDown(pl, button )

if(button == 13) then

--some code or maybe a function that encapsulates that code

end

return true

end

this code sucks because the more menus i add the bigger the function gets and also it gets harder to organize.

what you could do instead is create a function named after the keypress, in this case, we would create an object named keyPress and then:

keyPress = {}

keyPress[13] = function(pl, button)

print(pl:GetEyeTrace().Entity())

end

function GM:PlayerButtonDown(pl, button )

if(keyPress[button] ~= nil) then

keyPress[button](pl,button)

end

return true

end

now if i want to add the P menu, all i would have to do is create a function and assign it to keyPress[26].

anyway, sorry if my example didnt quite show how useful it is, but trust me, whenever you have a situation with multiple ifs try finding a way to run that code without the if, it will make your code much much better.
