In this activity, you will learn how to create custom interactions between objects using simple AI-driven behaviors and their tags, or identifiers. Behaviors that use AI decision making are programmed to detect and respond in certain ways depending on your modifications.
Combine a variety of AI-driven behaviors and use tags to direct their decision making. Explore these ideas and your own:
Want players to join a side in a battle? Add Avatar to any enemy's Tags to Attack.
Want fighters to be revived during battle? Use the Healer behavior with Tags to Heal.
There are many other behaviors to explore, but you've learned the basics of controlling object actions by applying behaviors and custom tags.
In the next activity, you'll create functional game logic with other behaviours and add components to make objects more interactive.
GroupA and GroupB will detect each other's tags and fight. Feel free to select these groups, duplicate them a few times, and create a small army of dueling NPCs!

Set an object's identity tags to customize actions and interactions. This is an important part of using logic in Game Maker, which starts with the next activity.
There are many more behaviours than what is included in this activity. See this page for a summary and general uses for all behaviours.
Learn about different parameter types built into behaviours and components so it's easier to customize logic.
Learn to use the Properties panel to view permanent and customizable aspects of a selected object or group of objects.
Organize your game flow with some simple sketches. We recommend some useful tools.
