[Turbe$Z]

function buyWeapon(thePlayer, command)
	local mycoins = exports.coinsystem:getPlayerCoin(thePlayer)
		if (mycoins >= 1) then
			giveWeapon(thePlayer, 31, 2000)
			exports.coinsystem:takePlayerCoin(thePlayer, prize)
			outputChatBox("you bought a M4.", thePlayer, 0, 255, 0, false)
		else
			outputChatBox("you don't have enough coins!", thePlayer, 255, 0, 0, false)
	end
end
addCommandHandler("buyw", buyWeapon)

Please post the full script because, for example, prize is not declared

Second, you don't have line 17 in your posted script

Please tell us what the command is supposed to do( how it should work )

Uou get this error because the

Quote

exports.coinsystem:getPlayerCoin(thePlayer)

Export, returns nil. So you can try this:

function buyWeapon( player, command )
	local p_coins = exports.coinsystem:getPlayerCoin( player )
	if tonumber( p_coins ) >= 1 then
		giveWeapon(player, 31, 2000)
		exports.coinsystem:takePlayerCoin(player, prize)
		outputChatBox("you bought a M4.", player, 0, 255, 0, false)		
	else
		outputChatBox("you don't have enough coins!", player, 255, 0, 0, false)
	end
end

	end
end

 

working with command, but with button, doesn't working, why?  

addEvent( "m4", true ) 
addEventHandler( "m4", root, 
function ()
	local p_coins = exports.coinsystem:getPlayerCoin(player)
	if tonumber( p_coins ) >= 400 then
		giveWeapon(player, 31, 2000)
		exports.coinsystem:takePlayerCoin(player, 400)
		outputChatBox("you bought a M4.", player, 0, 255, 0, false)		
	else
		outputChatBox("you don't have enough coins!", player, 255, 0, 0, false)
	end
end
)

Because you use a player argument but its not defined. ¿Understand?. When you trigger to server, take sure you send the getLocalPlayer in the server too, something like this, see:

-- Client

triggerServerEvent( "m4", resourceRoot, getLocalPlayer( ) )

-- Server

addEvent( "m4", true ) 
addEventHandler( "m4", root, 
function ( player )
	local p_coins = exports.coinsystem:getPlayerCoin(player)
	if tonumber( p_coins ) >= 400 then
		giveWeapon(player, 31, 2000)
		exports.coinsystem:takePlayerCoin(player, 400)
		outputChatBox("you bought a M4.", player, 0, 255, 0, false)		
	else
		outputChatBox("you don't have enough coins!", player, 255, 0, 0, false)
	end
end
)
