Trigger Component

Example Usage

The trigger as it appears in the Scene View when gizmos are enabled. Triggers are not visible in play mode; they are only visible while editing in the mod editor.

Damage area

By having a trigger's On Stay event damage the activator of the trigger, you can create an area for players to avoid by constantly removing health while they are in the trigger. You could have the trigger kill the player who entered it and attach the trigger to a moving object for the player to avoid (think an obstacle course with swinging blades).

King of the hill

A king of the hill style game could be created by placing a trigger that rewards players for remaining inside it using actions with the On Stay event.

One use per player

Using the One Use Per Player attribute, you can make a trigger that can reward players with points, but stops players from repeatedly entering and exiting the trigger to gain many points.

Disable after triggered

Disable After Triggered can allow a trigger to only be usable by a single player. This can be used in minigames where to goal is to reach something first to win. You can make entering a trigger finish the game and reward the player as the winner by having the minigame win condition set to "Obtain Points" and the trigger's On Enter Action rewarding the number of points to win the game.
