SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill allows an agent to safely descend one block forward, handling slopes, edges, and shallow drops without falling or colliding.

Core Features & Use Cases

  • Controlled Descent: Safely moves the agent down by one block.
  • Collision Avoidance: Checks for and avoids collisions during movement.
  • Support Validation: Ensures the landing surface is safe and walkable.
  • Use Case: An agent needs to navigate a multi-level structure. It can use nav-descend to move from a higher platform to a lower one, ensuring it lands safely.

Quick Start

Use the nav-descend skill to attempt a controlled descent forward.

Frequently Asked Questions about nav-descend

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I make a game agent safely descend one block in a Minecraft-like environment?

To safely descend one block in a Minecraft-like environment, the agent executes a controlled forward descent into an adjacent lower cell. This validates descent bounds and prevents collisions to ensure safe landing on walkable surfaces.

What is controlled descent for agent pathfinding?

Controlled descent in agent pathfinding is the process of moving down shallow drops up to 1.2 blocks while handling slopes and edges. It ensures the agent lands safely without falling or colliding during navigation.

Can I use this navigation skill to drop an agent down slopes and edges?

Yes, you can use this navigation skill to drop an agent down slopes and edges. It specifically handles shallow drops up to 1.2 blocks, checking for collision avoidance and validating support for safe landings.

What is the best way to handle multi-level agent navigation without falling?

The best way to handle multi-level agent navigation without falling is using a controlled descent mechanism. It validates landing surfaces and checks bounds to move agents from higher platforms to lower ones safely.

Why does my agent collide when moving down a single block?

An agent may collide when moving down a single block if descent bounds are not properly validated. This skill prevents collisions by checking for safe, walkable surfaces before executing the forward movement.

Does nav-descend support drops deeper than 1.2 blocks?

No, nav-descend only supports shallow drops up to 1.2 blocks. It is designed for single-block controlled descents, handling slopes and edges while ensuring the landing surface is safe and walkable.
