The Game Rules system empowers builders to:
Build logic more efficiently for greater game performance
Design new gameplays and compelling mechanics: Tower Defense, Horror / Backrooms, Resource Management, Cooking Simulator, Survival, and more!
Enhance the functionality of object logic (behaviours and components)
Guide players better and add game polish
🆕 Using Multiple Gridboards and #connectors
The Game Rules system is a visual scripting tool in the Gameplay menu.
It allows you to use and manipulate values such as numbers, text, time, and true/false values.
Create custom mechanics, or use predefined game mechanics called Presets:
Collect Points | Time Trial | Point Race | Combo | Hunger | Poison | Shop
Rules are a sequence of steps carried out from top to bottom that can be reused in your game.
They offer new possibilities, mechanics, and shortcuts to solve complex problems.
Click a rule type to expand the list of options. Click on a rule in the list to add it to a gridboard.
Variables are the backbone of the Game Rules system. Almost every rule can or must work in combination with a variable.
They can be used to store information to build more complex logical systems and provide important information to players.
Variables are automatically created when you use a Preset in Game Rules (more information below) or if you paste a ruleset into a gridboard. You can also create any type of variable you want and change the variable used in a rule.
A variable can be renamed and its value can be changed, but it can not be modified to a different type or be applied differently.
Create the type of variable needed and how it will be applied, replace the old variable in a rule, and delete the old variable.
Rulesets are a way to visually organise a group of rules used for the same game mechanic.
Rules may be grouped into a Ruleset, but they still act independently when triggered:
The order in which rules are placed in a ruleset does not change the flow of logic.
A rule's message Out may trigger another rule in the same ruleset or in a different one.
Some rules may not send a message Out.
a rule may trigger another rule in a different gridboard.
Example
The Collect Points ruleset (a Preset) is a gameplay mechanic that includes a chain of two rules (shown in red below) and other rules that act independently of the others.
Presets are pre-built rulesets you add to a gridboard with a single click. This is a fast way to set up commonly used game mechanics and customise as needed.
When adding a Preset, all necessary variables and messages are automatically generated.
Presets are accessed with a button in the Island Menu on the left. Click on a Preset in the list to add it to a selected gridboard.
Customise messages sent/received, variables used, rule names, and more as needed.
Integrate the Preset to communicate with your object logic (behaviours and components) to activate the Preset's mechanics in your Experience.
Copy and paste Rulesets with CTRL

. Messages and variables are included!
Paste generated text into external sources like a notepad to share.
Paste into other Experiences to reuse your Ruleset!
A multiplayer Experience must be published to the map or shared to the gallery to view Ranking data during play or on the website.
NO DATE FILTER FOR GLOBAL RANKINGS... YET! Take a snapshot of global rankings at the end of your events for accurate data.
Numeric variables (Number, Decimal Number, Time) can be used to create player rankings.
Up to three variables can be used to sort player ranking data.
Sorting can be done in ascending or descending order per variable.

Trigger A rule is triggered by a message In. If a message with arguments is received, the argument value may be used in a rule's action.
Variable(s) A rule may use zero, one, or multiple stored values defined by name and type.
Action(s) An action to carry out (e.g., change a variable, compare values, display on the HUD, etc).
Message to Stop the Rule Some rules allow another message In to stop its actions.
Output An optional message Out may trigger another rule, object logic, or quest. A message with arguments may be sent for more complex logic or fewer rules.
Right click a Rule and use 🔼🔽 arrows to view details about each logic box.

Number - Integers (e.g., 255)
