Problems with bindKey + setVehicleEngineState.

[LucasMorais]

Hello. I am new at MTA/LUA scripting and I am trying to do a system that when I press one key, the engines turns on, and when I press another key, the engine turns off. But, when I type /bindit, enter the car and press the key, there is an error at the server console. It is like this: "Bad argument @ setVehicleEngineState". This is the system, it's server-side.

function engineOn(player, key, keyState, theVehicle) 
if(keyState == "down") then 
setVehicleEngineState(theVehicle, true) 
end 
end 
  
function engineOff(player, key, keyState, theVehicle) 
if(keyState == "down") then 
setVehicleEngineState(theVehicle, false) 
end 
end 
  
function bindTheKeys(player, commandName) 
bindKey(player, "j", "down", engineOn) 
bindKey(player, "k", "down", engineOff) 
end 
addCommandHandler("bindit", bindTheKeys) 

Thanks.

function engineOn(player, key, keyState) 
    if(keyState == "down") then 
    if not isPedInVehicle(player) then return end 
        local theVehicle = getPedOccupiedVehicle(player) 
        setVehicleEngineState(theVehicle, true) 
    end 
end 
  
function engineOff(player, key, keyState, theVehicle) 
    if(keyState == "down") then 
    if not isPedInVehicle(player) then return end 
        local theVehicle = getPedOccupiedVehicle(player)     
        setVehicleEngineState(theVehicle, false) 
    end 
end 
  
function bindTheKeys(player, commandName) 
    bindKey(player, "j", "down", engineOn) 
    bindKey(player, "k", "down", engineOff) 
end 
addCommandHandler("bindit", bindTheKeys) 

[LucasMorais]

Hey, thanks! It worked, but.. is there anyway to bind the keys without typing "/bindit"?

[Castillo]

Yup, there is, here:

addEventHandler("onResourceStart",resourceRoot, 
function () 
    for index, player in pairs(getElementsByType("player")) do 
        bindKey(player, "j", "down", engineOn) 
        bindKey(player, "k", "down", engineOff)      
    end 
end) 
  
addEventHandler("onPlayerJoin",root, 
function () 
    bindKey(source, "j", "down", engineOn) 
    bindKey(source, "k", "down", engineOff) 
end) 
  
function engineOn(player, key, keyState) 
    if(keyState == "down") then 
    if not isPedInVehicle(player) then return end 
        local theVehicle = getPedOccupiedVehicle(player) 
        setVehicleEngineState(theVehicle, true) 
    end 
end 
  
function engineOff(player, key, keyState, theVehicle) 
    if(keyState == "down") then 
    if not isPedInVehicle(player) then return end 
        local theVehicle = getPedOccupiedVehicle(player)    
        setVehicleEngineState(theVehicle, false) 
    end 
end

Thanks again. Can I ask you a question? (I am already, *laughs*) Can you teach me LUA?

[Castillo]

You welcome.

And... I haven't got much time even for myself, also I suck at explaining, sorry dude .

[LucasMorais]

That's okay. But I hope that you answer all my questions

Just kidding.

[Castillo]

Hehehe, I'll always help here when I can, I like to help ppl around, to learn and then they'll help others in future (I hope ) .

By the way, i want to make some work with GUI now. I want to start with something like... a phone system. If i want to do an iPhone, do I need a clean image, without the icons or it can be with the icons? (I'll see the topic tomorrow, gotta sleep)

[Castillo]

Well... I would say that you need it without the Icons, and they has to be apart, else they'll be just part of the iPhone main image.

P.S: I suggest you to use guieditor for GUI/DX Drawing scripts .

[LucasMorais]

Okay, but... how do I use the guieditor and how I use it to do the GUI part of the iPhone?

[Castillo]

Meh, maybe you should real his description?

[LucasMorais]

Well, I have it in my pc, but I rode the description and I didn't find the way to make it work.

[Castillo]

I don't want to be rude... but, it explains how to use it.

Usage:

- to start editing type /guied or press shift + g, do it again to stop

- to edit a GUI element right click on it

- the parent of the element you are creating will be the element you right clicked on

For example: right clicking a window and selecting "Create Button" will create a button within the window

[LucasMorais]

No, not like that. I put it in "server\resources\guieditor", but I don't know what command I need to type to "activate" it.

[Castillo]

guieditor is a resource just like any other, type /start guieditor and done.

WARNING: DON'T PUT THE RESOURCE AS A .ZIP, MUST BE A FOLDER ONLY.
