Trailblazer
Trailblazer is a Fabric minecraft mod that changes blocks as they are walked on by players and mobs.
By default, the mod enables two trailblazing effects:
Dirt Trails. As players and zombies walk on grass blocks, the grass will change to dirt and then to paths...unless you're going barefoot or wearing boots enchanted with Feather Falling.
Firewalker Boots. If you're wearing Netherite Boots enchanted with Fire Protection and Frost Walker, Lava blocks will change to cobblestone as you walk on them.
Features
- Does NOT add any new blocks to your world.
- Does NOT have to be installed on the client
- Fully customizable. Change the default effects or create your own.
- Mobs and players can leave trails
- Trails can be enabled or disabled depending on boots/enchants being worn
- Change any block to any other block
- Can work with boots and enchants from any other mod.
