How triggers fit into a chain

Triggers detect input, state , collisions, timing, and other conditions. They begin a chain but do not perform gameplay actions by themselves.

  1. Choose the event or condition to detect.
  2. Configure filters, thresholds, or stored values.
  3. Connect the trigger to a Gate , then to one or more Actions.

Always

UI

Always active while enabled.

Menu Add Logic Brick → Triggers

Options

Property Details
enabled Enabled
Default: true
Using this brick

Typical uses

  • Start a logic chain when always active while enabled.
  • Gate an action through a Gate so multiple conditions can be combined.
  • Use it as the event or condition at the beginning of a reusable chain.

Example chain

Always Gate Choose an action
Tip Connect the trigger to a Gate even when only one condition is needed; this keeps the chain easy to expand later.
Common mistake A trigger only detects a condition. It does not perform an action until it is connected through a Gate to an Action.
