Trigger Logic

This activity is included in an 8-part, 1 hour series to learn Game Maker. Short, focused topics with guided practice will give you practical experience building useful logic for creating games.

Begin Game Maker 5

Trigger Logic with Messages

🟡 MEDIUM

In this activity, you will learn how to set up behaviors and components to create simple logic systems with objects as you explore the basics of communications in Game Maker using messages to create cause and effect.

Start

Launch Game Maker

• Open or create an Experience and move to an area with empty space.

• Let's turn the grid off and focus on logic.

Some behaviors and components are only available as [MP], which means they are multiplayer synchronized. For this activity, choose [MP] only when a [SP] option isn't available.

Designing gameplay with [SP] and [MP] logic will be explored later.

Using Messages

Trigger & Filter

Trigger Many Objects

Messages with Arguments

Follow Up

This activity introduced new tools and concepts to understand objects more and how to make them communicate in custom ways.

In the next activity, you will learn to integrate quests with some of the logic from this activity so you can begin designing a flow for players with clear guidance to play through your Experience.

Ready for More Practice?

This activity leaves room for you to test out your own ideas when the player exits the Trigger Volume and the message Day is sent. Test out custom weather profiles and light colours, too!

Remember that the special message LightColor sets transition timing and colour.
