To create a script that changes the global price of diesel to reflect the Polish reality of approximately EUR 6.30 per liter, you can follow these steps:
1. Open the game's script editor and create a new script file for the diesel price modification.
2. In the script file, you can set the base price range for diesel between PLN 6 and PLN 8 per liter. You can use a random function to give some variability to the price within this range.
3. To make purchasing diesel at a fuel tank more expensive than at a gas station, you can add a multiplier to the price when bought at a fuel tank.
4. Since you want the price to be close to EUR 6.30 per liter, you can convert this value to PLN and adjust the price range and multiplier accordingly to achieve the desired result.
5. Make sure to add the necessary code for multiplayer support, such as syncing the diesel price between players in a multiplayer session.
6. Finally, remember to include a disclaimer in the script file stating that reuploading the mod to other sites is prohibited.
By following these steps, you should be able to create a script that changes the global price of diesel in the game to match the Polish reality and ensure a realistic gameplay experience.
