Object Game Settings

Trigger Zone

Trigger Zone settings turn an object into an event area or event controller that can start other gameplay changes.

What it controls

What this group controls

Use this page as the detailed reference for the Trigger Zone group inside the Object Game Settings menu.

Event Object

A trigger zone listens for a condition, then activates configured behavior elsewhere in the level.

Activation Sources

A zone can activate on creation, intervals, contact start, contact end, force threshold, direction, control input, damage, motor limits, character death, or another trigger.

Contact Logic

Because sensors can detect contact without blocking movement, they are useful for invisible or pass-through trigger areas.

System Bridge

Trigger zones often connect physical motion to game logic, such as starting a platform when a ball reaches a switch.

How it works

How it behaves during play

These points describe what the system does after the level starts and the editor data becomes live gameplay behavior.

Condition Check

During play, the zone checks whether its configured activation condition has happened.

Target Action

When activated, it can start or stop another behavior, change object state, activate a chip, control a gun, modify smart follow patrol, or continue a trigger chain.

Repeat Rules

Interval and repeated contact triggers can fire more than once, while one-shot setups should be used when the action must happen only once.

Direction And Force

Directional and force-based rules let the same contact area behave differently depending on how an object enters or hits it.

Setup flow

Practical setup checklist

Use this checklist while building or debugging a level that uses Trigger Zone.

Make The Zone Readable

Use visible art, level layout, or predictable placement so the player understands why something happened.

Choose A Clear Source

Pick one primary activation source first, then add extra sources only when the design needs them.

Control Repetition

Decide whether the trigger should fire once, repeatedly, or only after another system re-enables it.

Test Contact Order

Run the level with slow and fast collisions because trigger timing can change when objects hit at different speeds.

Start and stop connected chips

Trigger zones can control a connected chip in addition to motors, objects, paths and patrols.
