Minecraft spiders have always been able to scale walls, but what if mod developers could give that same ability to any entity? Advanced Wall Climber API Mod (AWCAPI) is a utility library that makes exactly that possible — providing a complete framework for 3D surface movement, smooth rotation transitions, and intelligent pathfinding across walls and ceilings. If you're a mod developer looking to create creatures that crawl across every surface in your world, this API handles the heavy lifting so you don't have to.
Key Features
- 3D Surface Movement — Entities can move freely on walls, ceilings, and other vertical surfaces, creating spider-like climbing mechanics for custom mobs.
- Smooth Rotation Handling — When an entity transitions between floor, wall, and ceiling, its rotation adjusts naturally to avoid sudden or jarring movement snaps.
- Advanced 3D Pathfinding — A custom pathfinding system built specifically for multi-surface navigation, allowing entities to find reliable paths across different surfaces.
- Rendering Utilities — Includes helper tools that keep entity models properly aligned while climbing, which is especially useful for mods that render custom mob models.
