This is a personal pack designed to add some features from the game Hytale. I decided to share it in case anyone else was looking for something like this.
If you want to replicate a few things from Hytale, like jump height, step up/auto climb and block reach, use these commands when you start a world:
/attribute @p minecraft:jump_strength base set 0.55
/attribute @p minecraft:block_interaction_range base set 5.0
/attribute @p minecraft:step_height base set 1.0
If there is any mod you think should be added or something tweaked, please leave a comment.
