# XOR

**Category:** Gate
**Tier:** Basic

## Purpose

Outputs TRUE when EXACTLY ONE connected input listener is active (exclusive or).

## 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/xor_gate.png" alt="XOR 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>
```

## When To Use

- Mutually exclusive actions (walk XOR run, not both)
- Toggle switches (press A or B to toggle, not both)
- State machines (in exactly one state at a time)
- Single-choice selections (select one option only)
- Conflict detection (error if multiple conditions true)

## Runtime Behavior

**Triggers**: When exactly one connected input is TRUE (not zero, not multiple)

<div class="illustration-container">

            <div class="box-header">Generated UI Mockup — showing expanded properties</div>

                    <div class="real-controls"><div class="real-checkbox"></div><div class="real-btn">-</div><div class="real-btn">x</div></div>
                </div>

            </div>
        </div>
    </div>
```
