I've written this event module to make it easy to add keyboard and mouse button binds and it's come in handy to me for quite a few little scripts.
Once again excuse the poor spacing as copy and paste here seems to remove my tabs.
event.lua
-- Event module written by Averice event = {} event.inputBinds = {} event.mouseBinds = {} function event.CheckInput() local succ, err; for key,tab in pairs(event.inputBinds) do if( App.window:KeyHit(key) ) then for k, v in pairs(tab) do if( not v.Held ) then succ, err = pcall(v.Func, unpack(v.Args)); if not succ then print("Event Error[Key]["..k.."]: "..err); end end end end if( App.window:KeyDown(key) ) then for k, v in pairs(tab) do if( v.Held ) then succ, err = pcall(v.Func, unpack(v.Args)); if not succ then print("Event Error[Key]["..k.."]: "..err); end end end end end for but, tab in pairs(event.mouseBinds) do if( App.window:MouseDown(but) ) then for k, v in pairs(tab) do succ, err = pcall(v.Func, unpack(v.Args)); if not succ then print("Event Error[Mouse]["..k.."]: "..err); end end end end end function event.AddInputBind(key, name, held, func, ...) local newInput = { Func = func, Args = {...}, Held = held or false } event.inputBinds[key] = event.inputBinds[key] or {}; event.inputBinds[key][name] = newInput; end function event.AddMouseBind(but, name, func, ...) local newInput = { Func = func, Args = {...} } event.mouseBinds[but] = event.mouseBinds[but] or {} event.mouseBinds[but][name] = newInput; end function event.RemoveInputBind(key, name) if( event.inputBinds[key] and event.inputBinds[key][name] ) then event.inputBinds[key][name] = nil; end end function event.RemoveMouseBind(but, name) if( event.mouseBinds[but] and event.mouseBinds[but][name] ) then event.mouseBinds[but][name] = nil; end end
It's usage is really straight forward, you import the script, and in your App.loop you'll put
event.CheckInput();
This will check for your binds and run them if needed so you don't have to fill your App.loop with key binds.
To add a keyboard bind "event.AddInputBind(key, name, held, function, args);
local function printStuff(...) print("Hello", ...); end event.AddInputBind(Key.A, "RandomName", false, printStuff, "How", "are", "you") -- varargs once again. --when the A key is pushed it should output, "Hello How are you"; -- if 'held' is true it will keep printing while it's held. --To remove it we use it's name and key. event.RemoveInputBind(Key.A, "RandomName"); -- Mouse bind functions are the same, just use event.AddMouseBind and event.RemoveMouseBind -- mouse bind functions are considered always held. Add a check to your function if you only -- want it done per click.
A quick snippet that I use in my splash screen with my StateManager module to cancel the splash if escape is pushed.
event.AddInputBind(Key.Escape, "__SHARDSPLASH", false, function() StateManager:Pop() end);
