Jump Delay Fix

⚡ 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 ON or OFF at any time.
• Active Profile: View or cycle between SMART, COMPETITIVE, and STABLE.
• 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.
