⚡ Jump Delay Fix
Jump Delay Fix is a lightweight, purely client-side Minecraft mod designed to eliminate vanilla jump delay for smoother, instant, and hyper-responsive movement. Built for casual survival, technical parkour, and competitive PvP!
In vanilla Minecraft, the client enforces an artificial post-landing delay counter before allowing another jump. Jump Delay Fix eliminates this delay, giving you instantaneous control over your movement while intelligently protecting against server lag-backs.
✨ Features
- 🚀 Instant Jump Response: Removes the hardcoded jump cooldown upon landing for immediate, fluid jumping.
- ⚡ Multi-Loader Support: Official builds available for both Fabric and NeoForge.
- 🧠 Smart Auto-Tuning: Dynamically analyzes server round-trip latency and rollback history to adapt jump timings on the fly.
- 💾 Per-Server Profile Memory: Automatically remembers and applies your preferred jump profile for each multiplayer server.
- ⚙️ In-Game Settings GUI: Seamlessly integrated into ModMenu (Fabric) and Mod Options (NeoForge), featuring an in-game hotkey and a one-click Reset to Defaults button.
- 📊 Visual Actionbar Feedback: Displays subtle, color-coded status updates directly above your hotbar when toggling states or switching profiles.
- 🛡️ 100% Client-Side: No server-side mod installation required—works on vanilla, Paper, Purpur, and modded servers alike.
🎮 Jump Profiles
Jump Delay Fix includes three distinct tuning profiles to fit any playstyle or connection quality:
| Profile | Timing Offset | Description | Recommended For |
|---|---|---|---|
SMART (Default) |
0 ticks |
Dynamically balances immediate responsiveness with rollback mitigation based on real-time server latency. | Everyday survival, parkour, and general multiplayer servers |
COMPETITIVE |
-1 tick |
Maximizes responsiveness with aggressive jump dispatch and tight latency validation. | PvP servers, speedruns, and low-ping environments |
STABLE |
+1 tick |
Introduces a conservative timing buffer with higher penalty recovery tolerance to prevent anti-cheat pushbacks. | High-ping connections, cross-continental play, or strict anti-cheat servers |
💡 Enable Auto-Profile Switching in the settings GUI to allow the mod to dynamically transition between profiles based on connection quality!
⌨️ Controls & Hotkeys
All keybinds are fully customizable in Minecraft's Options → Controls → Key Binds under the Jump Delay Fix category:
| Action | Default Key | Description |
|---|---|---|
| Toggle Mod On/Off | J |
Instantly enables or disables mod functionality with an on-screen notification. |
| Cycle Jump Profile | H |
Cycles sequentially through SMART → STABLE → COMPETITIVE. |
| Open Config GUI | O |
Opens the Jump Delay Fix settings screen directly without leaving your world. |
🧩 In-Game Settings Screen
Access the settings screen via hotkey (O), through ModMenu (Fabric), or via the Mod List (NeoForge):
- Mod State: Toggle the mod
ONorOFFat any time. - Active Profile: View or cycle between
SMART,COMPETITIVE, andSTABLE. - Auto-Switch: Enable or disable real-time latency/rollback auto-tuning.
- Reset to Defaults: Instantly restores factory baseline settings.
🛡️ Anti-Cheat & Multiplayer Safety
- Jump Delay Fix is strictly a client-side input responsiveness utility.
- It never alters vertical velocity values (
motion.y), modifies jump height, accelerates movement speed, or sends illegal packets. - The mod simply processes the client's jump input immediately upon confirmed ground collision, rather than waiting for vanilla's artificial post-landing cooldown.
- Jump Delay Fix respects your game state: jump attempts are safely inhibited during respawn transitions, player death, and sleeping.
