CHECK SELECTED ITEM

[ÆBKV]

How can I check if the player has selected an item?

addEventHandler("onClientGUIClick",root,
function()
  if source == button1 then
    getWeapon = guiGridListGetItemText(gridlist1,guiGridListGetSelectedItem(gridlist1),2)
    getAmmo = guiGetText(editbox1)
    triggerServerEvent("giveWeapon",localPlayer,getWeapon,getAmmo)
  end
end
)

 

[King12]

local gRow = guiGridListGetSelectedItem ( gridlist1 )
if gRow >= 0 then -- player selected something
  
  else
  
end

guiGridListGetSelectedItem will return -1 for Row if an item wasn't selected.

weapon = {
  {"Brass Knuckles","1"}
  }

getWeapon = -- How can i get the weapon id from the table??

Thank you, can you help me here too?

tonumber( weapon[1][2] )

Please explain me why "tonumber" when it is already a number?

"You can use tonumber as a quick check if a variable contains something convertible to a number."

That helped me a lot guys, thank you.

"1" is a string, tonumber converts it to a numeric value which is used in giveWeapon's argument for example.
