Welcome to Lesson 13 of the 2D Platformer Game Development series! 🎮 In this lesson, we’ll add a Health Potion feature to your game, which will allow players to restore their health when they’re in need. 🍷✨ We’ll also introduce the concept of saving inventory using PlayerPrefs so the player can collect potions as loot and use them when required. 🛠️

Health potions are a common gameplay mechanic in many games, allowing players to heal during their journey. By adding this feature, you’ll give players more control over their survival and create opportunities for exciting moments when they need that health boost.

Here’s what we’ll cover in this lesson:

🍷 Creating the Health Potion Item
We’ll start by creating the health potion item that will be used to restore health. You’ll learn how to design the potion sprite and implement it as an interactable item in the game world. The potion can be picked up by the player when they collide with it, just like any other collectible item.

🛒 Using PlayerPrefs to Save Potion Inventory
We’ll show you how to use PlayerPrefs to save the number of health potions the player has collected. This is a simple and effective way to store data such as inventory items, even between game sessions. The number of potions will persist, so when the player returns to the game, they can use their saved potions. You’ll learn how to increment the potion count each time the player picks up a potion.

🧰 Displaying the Potion Count in the Toolbar
We’ll create a small toolbar UI to display the number of health potions the player has collected. This will make it easy for the player to see how many potions they currently have available to use. The toolbar will be shown at the top or bottom of the screen and will update automatically whenever the player picks up a potion.

⚡ Using the Health Potion to Restore Health
Now, we’ll link the health potion to the player’s health system. We’ll teach you how to make the health potion usable. When the player clicks on the potion in their toolbar, it will restore a set amount of health. We’ll show you how to decrease the number of potions in the inventory when a potion is used and how to prevent using potions if none are available.

🧪 Making Health Potions as Loot
To make the game more dynamic, we’ll implement a system where health potions are dropped as loot by enemies or objects in the game world. This means that as the player progresses, they’ll be able to collect potions dropped by enemies or chests, making it a rewarding mechanic for the player.

🎮 Potion Pickup Mechanism
We’ll implement a simple pickup mechanic where the player can collide with a health potion and automatically add it to their inventory. You’ll learn how to manage the inventory system and update the UI when a potion is added.

🔄 UI Updates When Potions Are Used
We’ll ensure that the UI updates correctly when a health potion is used, and the number of potions in the toolbar will decrease. We’ll also show you how to add visual effects or animations to make the potion usage more satisfying, such as a healing animation or a sound effect when the player uses the potion.

💡 Tips for Game Balance
We’ll briefly discuss how to balance the number of health potions that are available to the player. It’s important to make sure that potions are not too easy to find but still give players a sense of relief when they use them. Balancing this mechanic properly will add tension and reward to the player’s survival.

By the end of this lesson, your game will have a health potion mechanic that players can use to restore health. 🍶 The player will be able to collect potions as loot, use them in times of need, and see their potion count displayed in a handy toolbar. This will enhance the gameplay and give players a meaningful way to manage their health during their adventure.
