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.

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.
 
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!
