About this project
What does Iron Ladders add?
The mod adds new ladder variants made from different materials. More expensive materials provide faster climbing speed
Features:
- Morph ladders: change appearance without changing stats
- Styler Tool: change a ladder’s look by cycling model variants
- Use the Sensor Tool to add an entity detector that outputs redstone, or the Light Tool to light up ladders
Configuration:
- Adjust ladder speed bonuses (global + per ladder)
- Set the default ladder model (e.g., use the vanilla model)
- Hide uncraftable ladders when required non-vanilla materials are missing
- Toggle multi-variant ladder visuals (subtle random texture variations)
Recipes:


Ladder models:
Set a default in the config, or switch models in-game with the Styler Tool

Compatibility with other mods:
- JEI/REI/EMI:
- Read Item descriptions
- Hide unavailable ladders from their panels when required materials are missing (configurable)
- Jade / The One Probe / WTHIT:
- See the current ladder morph/model state
- See whether attachments are hidden by the Casing Tool
- Get contextual hints while using ladder tools
