About this project
What does Fast Block Placement add?
🏗️ FastBlockPlacement: The Ultimate Construction Companion
Are you tired of the painstaking process of placing blocks one by one? Does your massive mega-base project feel like it’s going to take a lifetime to finish? FastBlockPlacement is a high-performance utility mod designed to revolutionize your Minecraft building experience.
By removing the standard delays in block placement, FastBuilder allows you to create massive walls, floors, and structures in a fraction of the time it would take normally. Whether you are a creative mode visionary or a survival mode architect, this mod is the power tool you’ve been waiting for.
⌨️ Keybinds & Controls
The mod is designed to be as unobtrusive as possible. By default, the controls are mapped to the following keys (though you can change these in your standard Minecraft Controls menu):
[V] Key — Toggle Power: Instantly switch the rapid-placement engine On or Off. A handy way to swap between precision detailing and high-speed building.
[O] Key — Settings Menu: Access the configuration overlay to fine-tune your building experience.
🛠️ Customization & Server Safety
FastBlockPlacement is fully configurable to ensure it works exactly how you need it to. Within the settings menu, you can adjust the Placement Delay.
Singleplayer Mode: Feel free to set the delay to 0 or 1 for near-instantaneous block placement. Go as fast as your hardware can handle!
Multiplayer/Server Mode: It is highly recommended to use a 3-4 delay when playing on a server. Most servers have anti-cheat plugins that monitor how fast a player interacts with the world. A delay of 3 or 4 usually mimics fast human clicking and is much safer for online play.
⚠️ Important Disclaimer
While FastBlockPlacement is a productivity tool, please use it responsibly. Many multiplayer servers categorize "FastPlace" mods as an unfair advantage or a "ghost client" feature.
I am not responsible if you get banned or kicked from a server for using this mod. Always check the specific rules of the server you are joining. If "FastPlace" or "Macro" mods are forbidden, do not use this mod on that platform.
