Lesson 4.6: Add Keyboard Shortcuts for Game Operations

Part of a good game is being able to take multiple forms of input. To this point, we have focused on touch and mouse input.

Lesson 4.5: Craft Items with Recipes

With the popularity of games like Minecraft, building and crafting items from base components has become very common in games. It has found its way into many of the latest roleplaying games as well.

Lesson 4.4: Create the First Consumable Item

Most game players are familiar with consumable items - these are single use items that are used to provide the player an effect... like a potion of healing that lets us rejuvenate some of our hit points.

So we are going to add methods with additional logic to handle these behaviors. … Continue reading Lesson 4.1: Adding Hit Point, Gold, and Level Management

Lesson 3.11: Adding Quests to Locations

Quests are a core concept of any roleplaying game. Various people send our player off on quests to kill some monsters, return with items for potions, retrieve the secret stone, and so much more. These provide some of the motivations for our heroes to adventure. Then when the player completes the quests, they may get … Continue reading Lesson 3.11: Adding Quests to Locations
