# Gate Reference

Generated reference pages for GDLink gate bricks.

| Brick | Purpose | Tier |
|---|---|---|
| [AND](and_gate.md) | The AND gate outputs a positive pulse only when ALL connected input sensors are active simultaneously. | Basic |
| [OR](or_gate.md) | Outputs TRUE when ANY connected input listener is active. | Basic |
| [XOR](xor_gate.md) | Outputs TRUE when EXACTLY ONE connected input listener is active (exclusive or). | Basic |
| [NAND](nand_gate.md) | Outputs TRUE when NOT all connected inputs are active simultaneously. | Basic |
| [NOR](nor_gate.md) | Outputs TRUE when NONE of the connected inputs are active. | Basic |
| [Expression](expression_gate.md) | Evaluates custom boolean expressions with complex logic, allowing arbitrary combinations beyond simple AND/OR/XOR gates. | Basic |
| [State](state_gate.md) | Implements a finite state machine (FSM) gate that only activates outputs when in specific states, with bitmask-based state filtering. | Basic |
| [GDScript](gdscript_gate.md) | Executes custom GDScript code to make complex decisions that can't be easily expressed with logic gates or expressions. | Pro |
| [XR](xr_gate.md) | Pure boolean filter for XR-specific conditions. | Pro |
