About this Mod
Better Auto-Jump
A Minecraft Fabric mod that replaces and vastly improves the vanilla auto-jump system. Client-side only.
Features
- Improved Auto-Jump -- Predicts collisions in the direction of movement and automatically jumps over blocks up to a configurable height. Accounts for the Jump Boost potion effect and respects an angle threshold so you only jump over blocks in your general path.
- Edge Jumping (Parkour Helper) -- Detects when you're approaching the edge of a block while moving forward and triggers a jump just before the edge. (Disabled by default, enable in mod's settings)
Configuration
Edit <game_dir>/config/better-auto-jump.json manually, or use the Mod Menu GUI (recommended). The GUI offers:
- Master Toggle -- Enable/disable the entire mod.
- Obstacle Jump / Edge Jump -- Individual feature toggles.
- Preset Selector -- Switch between built-in and saved custom presets.
- Variance / Cooldown -- Random tick delay (0–5) and minimum ticks (1–10+) between edge jumps.
- Advanced Settings -- Fine-tune all detection parameters and save custom presets.
