Extendable Ladders Mod is a useful mod that introduces two important ladder types to Minecraft. The biggest highlight of this mod is definitely the fact that these ladders are quite easy to place and remove, even when across open space. This mod is great promising to deliver extra depth to the game.
In the picture below on the left is a rope ladder. When activated, it removes additional role ladders from your inventory to build downwards until it either encounters a non-air block or you run out of ladders. Can only be removed from the top-most block. Right, Extending Ladder, when activated it removes additional extending ladders from your inventory to build upwards until it either encounters a non-air block, a solid block it can rest on, or you run out of ladders. Can only be removed from the top-most or bottom-most block. All used blocks will be returned when broken.
The ladders render correctly from both sides (unlike the vanilla ladder which expects that there’s a solid block behind it). (The “pulley rope” for the extending ladder has altered since the screenshots to be significantly less wavy.)
