Question about input.IsKeyDown

[Johnelectron]

Hey, I am fairly new to lua and have a problem with the input.IsKeyDown() function.

No matter how I use it
Ex:

hook.Add( "Think", "keypress_test", function()
    if input.IsKeyDown( KEY_SPACE ) then
        print("You pressed space")
    end
end )

I always get the same error:

[ERROR] lua/test.lua:2: attempt to index global 'input' (a nil value)
1. v - lua/test.lua:2
2. unknown - lua/includes/modules/hook.lua:84

I understand what this means, it simply states that "input" is not defined, which doesn't make any sense... I just haven't seemed to figure this out, or see anyone with the same problem. Thanks if you can help!

Again, I know this is simple stuff, I literally started programming in lua today :p

From seeing lua/test.lua I can assume you have this open in a server side file.
That code works client side.

Create yourself an easy workspace. Create a base gamemode, create init.lua, cl_init.lua and shared.lua.
Look it up online how to do this correctly, then put that code in cl_init.lua your client side file.

I've tried running it client side before, but apparently with me being too stupid to think to restart the server it didn't work.
I restarted the game, ran the code client side and it worked great.

Thanks for the help.
