Advanced Roulette System (TFS 0.3.6)

 

Hi everyone! This is my first contribution to the Tibia community, and I hope you find it very useful. It's a gacha-style roulette system with dynamic speed mechanics and multi-key functionality.

 

What's it about?

This script adds a roulette (Tested on: Tibia 8.6 -- TFS 0.3.6) where players can use keys to spin the roulette and win rewards. The system includes:

• Multi-key support: using 1 to 4 keys per spin, increasing the chances of winning.
• Dynamic speed: The roulette gradually accelerates during the spin to make it more exciting.
• Configurable rewards: You can define which items can be won and with what probability. You can even add "reroll" value to increase the difficulty!
• Visual effects: Includes simple effects and text animations to make the experience more engaging.
• Activity log: Keeps a record of which players won which items.

Installation

1. Copy the `Roulette.lua` file to the `data/actions/scripts` folder of your TFS server.

       addEvent(shuffle, config.initialSpeed, cid, pos, rewardId, 1, {}, keyName, requiredKeys) -- Start the roulette animation.
       return true
   end

    

2. Add the following lines within the `<actions>` tag in your `data/actions/actions.xml` file:

   <action actionid="XXX;YYYY;ZZZZ;AAAA" event="script" value="Roulette.lua"/>

   Replace `XXXX`, `YYYY`, and `ZZZZ` with the unique IDs of the levers that will activate the roulette (make sure they are not in use!).
   The ID `AAAA` is for the lever that changes the number of keys to use.
    

3. Open the `Roulette.lua` file and adjust the `config.items` table with the items you want players to be able to win. Remember to balance the probabilities.

 

 

Code Explanation
The script is divided into several sections to facilitate understanding:

• LOGGING SYSTEM: Handles logging the rewards obtained by players.
• BASE CONFIGURATION: Defines object IDs and reward levels.
• MAIN CONFIGURATION: Contains the main options of the system, such as the wait time between spins, the speed of the roulette, and the rewards.
• PROBABILITY CACHING: Optimizes the calculation of probabilities so that the system runs smoothly.
• UTILITY FUNCTIONS: Helper functions to calculate speed, choose items randomly, and update the roulette display.
• WINNER SLOTS AND EFFECTS: Displays the "Winner Slot" text and other visual effects in the winning spaces.
• MAIN ROULETTE LOGIC: The main function that controls the roulette animation and the delivery of rewards.
• PERIODIC EFFECTS AND TEXTS: Displays effects and texts periodically.
• SCRIPT INITIALIZATION: Initializes the effect system when the script is loaded.
• MAIN OBJECT USE FUNCTION: The function that is executed when a player interacts with a lever.
  
  I hope this roulette system is a great addition to your server! If you have any questions or suggestions, please feel free to leave a comment. Thank you for your support!
