# XR

**Category:** Gate
**Tier:** Pro

## Purpose

Pure boolean filter for XR-specific conditions.

## Visual Reference

```{raw} html
<div class="illustration-container"><div class="illustration-box"><div class="box-header">As added to your scene</div><img src="https://gdlink.solventech.ca/guide/assets/images/bricks/xr_gate.png" alt="XR brick as it appears in the GDLink editor" loading="lazy" style="max-width:100%;height:auto;display:block;margin:0 auto;border-radius:8px;" /></div></div>
```

## Runtime Behavior

**Inputs**
- **Pulse** (Boolean): Upstream pulse from a listener. Blocked or passed based on check result.

**Outputs**
- **Pulse** (Boolean): Passed through when gate condition evaluates true.

**Properties**

**Core (always visible)**
- **check_type** (Enum, default `"Gesture"`): `Gesture`, `Tracking Confidence`
- **tracker_hand** (Enum, default `"Right"`): `Left`, `Right`

**Gesture Mode (`visible_if: {check_type: "Gesture"}`)**
- **required_gesture** (Enum): `Pinch`, `Grip`, `Point`, `Open Hand`, `Fist`
- **strictness** (Float, default `0.8`): Confidence threshold (0.0-1.0) required for the gesture to be recognized.

**Tracking Confidence Mode (`visible_if: {check_type: "Tracking Confidence"}`)**
- **min_confidence** (Enum): `High`, `Medium`, `Low`
- **lost_behavior** (Enum, default `"Block"`): `Block` (fail closed), `Invert` (pass when tracking lost)
- **hysteresis** (Float, default `0.1`): Prevents rapid toggling at confidence boundary.
