Fast Block Place Mod 1.8.9 -

While primarily a FPS boost mod, Patcher includes a "Placebo" block place fix that reduces latency in singleplayer and local servers.

package com.yourname.fastplace;
import net.minecraftforge.common.config.Configuration;
import net.minecraftforge.fml.common.event.FMLPreInitializationEvent;
import java.io.File;
public class Config 
public static boolean fastPlaceEnabled = true;
public static boolean fastBreakEnabled = false;
public static void load(FMLPreInitializationEvent event) 
    File configFile = new File(event.getModConfigurationDirectory(), "fastplace.cfg");
    Configuration config = new Configuration(configFile);
    config.load();
fastPlaceEnabled = config.getBoolean("FastPlace", "general", true, "Remove right-click delay");
    fastBreakEnabled = config.getBoolean("FastBreak", "general", false, "Remove left-click delay");
config.save();

Update the tick handler to check Config.fastPlaceEnabled. fast block place mod 1.8.9

FBP circumvents the client-side delay while attempting to avoid server-side detection. The implementation varies, but common methods include:

The mod overwrites the onTick() method in NetHandlerPlayClient or directly patches the rightClickDelayTimer decrement logic. Example pseudocode of the patch:

// Vanilla (simplified)
public void onTick() 
    if (this.rightClickDelayTimer > 0) 
        this.rightClickDelayTimer--;
// Fast Place Modification
public void onTick() 
// Force timer to 0 every tick
this.rightClickDelayTimer = 0;

Minecraft version 1.8.9 is the competitive PvP community's "gold standard." Unlike later versions (1.9+), 1.8.9 lacks attack cooldowns, retains sword blocking, and—crucially for this topic—has a block placement system that is client-authoritative in certain respects. This means that while the server validates placements, the client predicts and renders them instantly. Fast block place mods exploit this architectural nuance.

Before installing:

package com.yourname.fastplace;
import net.minecraft.client.Minecraft;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;
import net.minecraftforge.fml.common.gameevent.TickEvent;
public class FastPlaceTickHandler 
@SubscribeEvent
public void onClientTick(TickEvent.ClientTickEvent event) 
    if (event.phase == TickEvent.Phase.START) 
        Minecraft mc = Minecraft.getMinecraft();
        if (mc.rightClickDelayTimer > 0) 
            // Force delay to zero – instant place
            mc.rightClickDelayTimer = 0;
// Optional: Force leftClickCounter to zero for fast break too
        if (mc.leftClickCounter > 0) 
            mc.leftClickCounter = 0;
