Get Input

[ViRuZGamiing]

Is there a way to get the input of keys? I could make a table with all keys and bind them to a input function.

But say for example if I press 'b' then b outputs in chat.

[NewbProgramming]

ROOT_ELEMENT = getRootElement(); 
  
OnKey = function(button, pressed) 
    -- source = client root 
    if pressed == true then 
        if button == "b" then 
            outputChatBox("You've pressed 'b'!"); 
        end 
    end 
  
    if pressed == false then 
        if button == "b" then 
            outputChatBox("You've released 'b'!"); 
        end 
    end 
    return; 
end 
  
addEventHandler("onClientKey",  ROOT_ELEMENT,   OnKey   );

- OR -

OnBKey = function(key, state) 
    if state == "down" then 
        outputChatBox("You've pressed 'b'!"); 
    end 
     
    if state == "up" then 
        outputChatBox("You've released 'b'!"); 
    end 
    return; 
end 
  
bindKey("b", "both", OnBKey);

local input = "" 
  
function getChatInput (button) 
    input = input..button 
end 
  
function drawChatInput() 
    dxDrawText(input, 430, 651, 935, 674, tocolor(255, 255, 255, 255), 0.60, "bankgothic", "left", "center", true, false, false, false, false) 
end 
  
addEventHandler("onClientRender", root, drawChatInput) 

I tried this it almost works, the only problem is it outputs every key twice.

[NewbProgramming]

What's calling getChatInput?

[ViRuZGamiing]

I've edited it here;

local input = "" 
local chatVisible = false 
  
function getChatInput (button) 
    input = input..button 
end 
  
function drawChat() 
    dxDrawRectangle(342, 648, 597, 29, tocolor(255, 255, 255, 255), false) 
    dxDrawRectangle(343, 649, 595, 27, tocolor(0, 0, 0, 255), false) 
    dxDrawLine(421, 652, 421, 672, tocolor(255, 255, 255, 255), 1, false) 
    dxDrawText("CHAT:", 343, 651, 421, 674, tocolor(255, 255, 255, 255), 0.60, "bankgothic", "center", "center", false, false, false, false, false) 
    dxDrawText(input, 430, 651, 935, 674, tocolor(255, 255, 255, 255), 0.60, "bankgothic", "left", "center", true, false, false, false, false) 
end 
  
function setChatVisible(state) 
    if (state) then 
        addEventHandler("onClientRender", root, drawChat) 
        addEventHandler("onClientKey", root, getChatInput) 
        toggleAllControls(false) 
        chatVisible = true 
        bindKey("escape") 
    else 
        removeEventHandler("onClientRender", root, drawChat) 
        removeEventHandler("onClientKey", root, getChatInput) 
        toggleAllControls(true) 
        chatVisible = false 
    end 
end 
  
function getChatVisible() 
    if (chatVisible) then 
        return true 
    else  
        return false 
    end 
end 
  
addEvent("setChatVisible", true) 
addEventHandler("setChatVisible", getRootElement(), function() 
    if (getChatVisible()) then 
        setChatVisible(false) 
    else 
        setChatVisible(true) 
    end 
end) 

the event setChatVisible is triggered by a bindKey added serverside onPlayerJoin:

function bindChat (thePlayer) 
    triggerClientEvent(thePlayer, "setChatVisible", thePlayer) 
end 
  
addEventHandler("onPlayerJoin", getRootElement(), function() 
    showChat(source, false) 
    bindKey(source, "t", "down", bindChat) 
end) 

[NewbProgramming]

onClientKey gets called twice per key press. The variable 'pressed' is set to true for key down and false for key up.

So...

function getChatInput (button, pressed) 
    if pressed == true then  
        input = input..button 
    end 
end

Oh so what I did was on press and release output it

BTW you don't need to check for booleans to be true

[NewbProgramming]

BTW you don't need to check for booleans to be true

I do it for neatness.

I also don't need to add semi-colons to end statements but I do it anyways.

[ViRuZGamiing]

This helped me all the way to the end thx I've almost made an entire basic chat system in +/- 1 hour.

Not that this is a problem but I keep getting 'Command of cvar unknown: chatbox' in my console.

I used showChat(false) to hide to default one.

[NewbProgramming]

Alright man.

I do not know what that means exactly. ("Command of cvar onbekend: chatbox")

Maybe an MTA team member or someone more experienced with MTA scripting can elaborate.

I've made me a custom chat box as well.

It's designed just like World of Warcraft's chat box.

I do not get anything like you're getting.

[tosfera]

You're actually still executing binds in the background, Viruz. You should make a check inside the onClientKey and see if the user is using your input. If it is, simply use cancelEvent and "return" to stop it from happening. The normal chatbox is bound to some keys and if you're using those without taking note of that, it'll start throwing random errors.

[ViRuZGamiing]

So can't I just unbind the chat? there is a MTA Hardcoded command 'chatbox' as far as I know.

But unbindKey("t", "both", "chatbox") didn't do the trick sadly.

[NewbProgramming]

From my knowledge you can't unbind any MTA controls, the player can but not the server nor the client scripts.

You have to toggleControl("chatbox", false).

The following are names of hard-coded MTA commands which do not use bindKey, but can act as bindKey by using them in an addCommandHandler. Other than that, this control list will only work with the functions toggleControl and toggleAllControls. Please note that toggleControl can't disable screenshot.

https://wiki.multitheftauto.com/wiki/Control_names

showChat(false) should have automatically disabled the control though.

[tosfera]

Try to skim down which buttons activates that chatbox bind. Press every button once and see which one triggers the error.

As I said 't' because t opens the chat

Try:

toggleControl("chatbox", false)

[ALw7sH]

Use onClientCharacter instead of onClientKey if you want to do custom edit

[ViRuZGamiing]

Actually onClientKey works better in my case because I use backspace and enter and such as well, newb didn't work

#Alw7sh this is how I did it,

local input = "" 
local chatVisible = false 
local keys = {"0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k",  "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z",  
"num_0", "num_1", "num_2", "num_3", "num_4", "num_5", "num_6", "num_7", "num_8", "num_9", "[", "]", ";", ",", "-", ".", "/", "#", "\\", "=", "space", "enter", "escape", "backspace"} 
  
function getChatInput (button, pressed) 
    if pressed then 
        for _, value in pairs(keys) do 
            if (button == value) then 
                if (button == "enter") then 
                    setChatVisible(false) 
                    outputChatMessage(input) 
                    input = "" 
                elseif (button == "escape") then 
                    setChatVisible(false) 
                    input = "" 
                elseif (button == "backspace") then 
                    input = string.sub(input, 1, #input-1) 
                elseif (button == "space") then 
                    input = input.." " 
                else 
                    input = input..button 
                end 
            end 
        end 
    end 
end

Damn man, it works for me no errors, let me scrap my system and send it to you.

[ViRuZGamiing]

It might be because I did it server sided, let me try it client.

EDIT: Nope still does

[tosfera]

What if you add a cancelEvent() after "if pressed then", might work. I've been creating custom inputs too but never had this problem..

[NewbProgramming]

I didn't see your code on the previous post until just now.

You DO NOT have to create a loop (it's inefficient), you can do this:

function getChatInput (button, pressed) 
    if pressed then 
        if keys[button] ~= nil then 
            if (button == "enter") then 
                setChatVisible(false) 
                outputChatMessage(input) 
                input = "" 
            elseif (button == "escape") then 
                setChatVisible(false) 
                input = "" 
            elseif (button == "backspace") then 
                input = string.sub(input, 1, #input-1) 
            elseif (button == "space") then 
                input = input.." " 
            else 
                input = input..button 
            end 
        end 
    end 
end 

It's 6:00am (06:00), I am going to sleep.

If you still need help when I wake up, I'll help you.

Private message me.

What if you add a cancelEvent() after "if pressed then", might work. I've been creating custom inputs too but never had this problem..

That makes me stuck in my typing situation. My dxDraw is drawn but my input is (as expected) cancelled.

[ViRuZGamiing]

if keys[button] ~= nil then[/lua]

This didn't work

[tosfera]

if keys[button] ~= nil then[/lua]

This didn't work

Really obvious that this didn't work, if you want to call the button as an index, you need to transform the table form a value based to an key=>value pair. You'll have to make it like;

table = { [ "a" ] = true, [ "b" ] = true }; 

Once you've done that, you can call it like; table [ button ]

Now, with that typing cancelled.. you're putting text in the box yourself, right? So what's wrong with the typing being cancelled? Are you still using other inputs somewhere else?
