Have a problem with give weapon script

[IMariukas]

Can somoene explain what's the problem?

local player = getLocalPlayer 
function buyweapon (player,command) 
takePlayerMoney ( player, 2000 ) 
        if true then outputChatBox ( "#00FF00Congratulations You Buyed M4 for 2000!", getRootElement(), 255, 255, 255, true ) 
        giveWeapon ( player, 31, 200 ) 
  end 
        else if false then outputChatBox ( "#00FF00You Don't Have Enough Money!", getRootElement(), 255, 255, 255, true ) 
    end 
addCommandHandler ( "buym4", buyweapon )

That script doesn't make any sense.

[IMariukas]

I wanted to make a simple test script where you write buym4 and if you have enough money it gives you weapon and writes on chat box and if you don't have enough money it only writes that you don't have enough money.

[Castillo]

Well, what you did doesn't make any sense.

You need the following functions:

addCommandHandler 
getPlayerMoney 
takePlayerMoney 
giveWeapon 
outputChatBox 

[IMariukas]

So what to write ??because i don't know what other to write with those "If" functions

[Max+]

addEventHandler('onPlayerCommand', root, 
function (cmd) 
    if (cmd == 'buym4' ) then 
    if(getPlayerMoney(source) >=2000 ) then 
    takePlayerMoney(source, 2000) 
    giveWeapon(source, 31, 200 ) 
     outputChatBox ( "#00FF00Congratulations You Buyed M4 for 2000!", source, 255, 255, 0) 
     else 
      outputChatBox ( "#00FF00You Don't Have Enough Money!", source, 255, 255, 0) 
  end 
  end 
end 
) 

[Castillo]

That's wrong Max, he should use addCommandHandler.

Why it's worng ?

An example:

addCommandHandler("giveM4", Give) 

[iPrestege]

function buyweapon (player) 
            if getPlayerMoney(player) >= 2000 then 
        takePlayerMoney ( player, 2000 ) 
            outputChatBox ( "#00FF00Congratulations You Buyed M4 for 2000!",player, 255, 255, 255, true ) 
        giveWeapon ( player, 31, 200 ) 
      else  
                outputChatBox ( "#00FF00You Don't Have Enough Money!",player, 255, 255, 255, true ) 
            end 
    end 
addCommandHandler ( "buym4", buyweapon )

Thank you Mr.Pres[T]ege Verry Much!

Thank you Mr.Pres[T]ege Verry Much!

Have you learned something from it? Cause this is kinda... first day of programming that people are learning you that this wont work;

 if true then 

What has to be true, what is true? Whats going on? O_O

A true/false is a returned bool value. So if you got a function that returns a boolean you can get 2 things back; True or False. So lets make a little script with it;

local pedInVehicle = isPedInVehicle(source); 
if (pedInVehicle) then -- if its true 
   outputChatBox("In a car!", source); 
else 
   outputChatBox("FALSE!, aint in a car brotha!", source); 
end 

Get it? (aint trying to be a btch or so, just want people to learn from their mistakes cause of my mistakes, I gained alot of knowledge)

Try this:

local player = getLocalPlayer 
function buyweapon (player,command) 
    if (getPlayerMoney(player) > 1999) then  -- 1999 will acculy be 200 
        outputChatBox ( "#00FF00Congratulations You Buyed M4 for 2000!", 255, 255, 255, true ) 
        giveWeapon ( player, 31, 200 ) 
        takePlayerMoney ( player, 2000 ) 
    else 
        outputChatBox ( "#00FF00You Don't Have Enough Money!", 255, 255, 255, true ) 
    end 
end 
addCommandHandler ( "buym4", buyweapon )

    end 
end 
addCommandHandler ( "buym4", buyweapon ) 

The problem solved in the first page but i have a question why you use localPlayer server side?
