Always

Category: Listener Tier: Basic

Purpose

The Always listener continuously outputs a positive pulse every tick, providing a constant activation signal for testing and basic logic flows.

Visual Reference

As added to your scene

Runtime Behavior

Inputs None

Outputs

• Pulse (Boolean): Always true (positive pulse every tick)

Properties

• use_pulse_mode (Boolean, true): When true, the listener pulses on a skip cadence (see frequency). When false, it fires continuously every physics tick (classic “always on” mode).

• frequency (Integer, 0): Number of ticks to skip between pulses while use_pulse_mode=true. 0 = fire every tick, 30 = fire once every half-second at 60 fps, etc.

• invert (Boolean, false): Output the logical inverse. With continuous mode the listener becomes always-false; with pulse mode, the skipped ticks are reported as true and the scheduled pulse tick flips to false. Useful for “silence canary” demos and watchdog-style guards.

Execution Behavior

Tick Behavior

• With use_pulse_mode=false, every physics tick outputs a positive pulse (continuous mode).

• With use_pulse_mode=true, the listener outputs a positive pulse, then skips frequency ticks before the next pulse. frequency=0 behaves like continuous mode.

• When invert=true, the listener outputs the logical inverse of the above behaviors (false during the would-be pulse window, true otherwise).

• Scene-start one-shot logic is handled by Delay with delay=0 and repeat=false; Always does not have a one-shot mode.

State Changes

• Initial state: ACTIVE

• Persistent state: ACTIVE

• No state transitions

Edge Detection

• Positive pulse: Generated every tick (ACTIVE -> ACTIVE)

• Negative pulse: Never generated
