Slot Machine

Slot Machine

AMX Mod X plugin for Counter-Strike.

The plugin allows you to place slot machines on the map and play them. The player places a bet and waits for a winning combination of symbols to appear. A victory is counted when a whole row or diagonal is filled with the same symbols. There is an API for adding your own prizes and a tool for customizing the slot machine model.


  • slot_machine — menu for placing slot machines on the map.


The plugin configuration is stored in the directory addons/amxmodx/configs/slot_machine. The file _pattern.json contains a 3 by 8 matrix with symbol markings for the reels of the slot machine. The symbol is defined by a number from 0 to 7. The symbol index is the same as the prize index. At the moment, it is not possible to change the dimension of the matrix. Example configuration file content:

	[0, 1, 2, 0, 3, 2, 4, 5],
	[1, 0, 2, 4, 0, 2, 3, 5],
	[2, 0, 3, 4, 2, 0, 5, 1]

Adding your own prizes and bets

The next21_slot_machine.sma source code file contains only the basic functionality of the plugin without issuing rewards. Prizes and bets must be implemented in a separate plugin using a dedicated API for this purpose:

 * Called when a client wins a slot machine
 * @param 	iPlayer			- Client index
 * @param	iPrize			- Prize index
forward client_slot_machine_win(const iPlayer, const iPrize)

 * Called before the slot machine is activated by the client
 * @param 	iPlayer			- Client index
 * @return					- Use PLUGIN_HANDLED if you want to disable slot machine activation
forward client_slot_machine_spin(const iPlayer)

The file addons/amxmodx/scripting/next21_slot_machine_money.sma contains an example of the implementation of the money system for a slot machine:

#include <slotmachine>

#define BET 100

new const GAME_PRIZES[] =

public client_slot_machine_win(const iPlayer, const iPrize)
    new iAddMoney = GAME_PRIZES[iPrize]
    rg_add_account(iPlayer, iAddMoney)

public client_slot_machine_spin(const iPlayer)
    if (get_member(iPlayer, m_iAccount) < BET)

    rg_add_account(iPlayer, -BET)

Customization of the slot machine model

The script allows you to relatively quickly generate the texture and UV-layout of the reels according to the specified parameters. For this you need:

  1. Place addons/amxmodx/configs/slot_machine/_pattern.json file in cfg directory.
  2. In the file cfg/text.json specify the names of bets and prizes, colors of text and shadows.
  3. Place images of reel symbols into the symbols directory. File names must match the symbol numbers (from 0 to 7).
  4. Run the script using the Python 3 interpreter. The Pillow module must be installed in the system.
  5. Compile with studiomdl or any other compiler the slot machine model in the dist directory.

The quality of the generated textures may not be high enough. To solve this problem, it is proposed to re-save the resulting images with the png extension in any other raster editor (like GIMP).
