Hello guys
I want some changing in the following lua,
I want to make Shop in my map and add the shop in specific place, when player press Button "E" at the tile (Example: 23|1 ) Instead saying !shop like in this lua code so Shop will be opened.

You can use the cs2d lua hook

usebutton hook to trigger a specific event such as showing a menu when the player presses the E key on a button of the map. Here is an example of code:

1
2
3
4
5
6
7
8
9
10

function MenuShopOnUse(id, x, y)
   local PosX = 0 -- The position in X coordination
   local PosY = 0 -- The position in Y coordination

   if (x == PosX and y == PosY) then
      -- Code here
   end
end

addhook('usebutton', 'MenuShopOnUse')

You've to fill

PosX

and

PosY

variables with the actual position of the button on the map. Keep in mind however that you need to set trigger_use entity on that position in order to make it work (as explained by the documentation).
