🧱 Falling Blocks FPS Fix

Clean up falling sand and gravel before they can destroy your performance!

Falling Blocks FPS Fix is a lightweight performance and utility mod that removes nearby falling sand and gravel entities while still preserving their item drops.

This is especially useful in modpacks, large builds, collapsing terrain, world-generation areas, or situations where hundreds of falling blocks can cause heavy FPS drops, server lag, or temporary freezes.

🎛️ Falling Block Cleaner GUI

Press:

H

to open the Falling Block Cleaner screen.

Inside the GUI, you can configure the following options independently:

• 🪨 Falling Gravel: Allowed / Disabled
• 🏖️ Falling Sand: Allowed / Disabled

This allows you to disable only the falling block types that are causing problems.

---

🪨 Falling Gravel

When Falling Gravel is set to Disabled:

• Nearby falling gravel entities are detected
• The moving falling block entity is removed
• A gravel item is dropped in its place

This means the gravel is not completely deleted. You can still collect the resource normally.

---

🏖️ Falling Sand

When Falling Sand is set to Disabled, the mod removes:

• Sand falling entities
• Red sand falling entities

Just like gravel, the removed falling block still drops its corresponding item.

---

🎁 Item Drops Are Preserved

The mod does not simply delete your sand or gravel.

Before a matching falling block entity is removed, the mod creates an item drop for that block.

For example:

• Falling gravel becomes a gravel item
• Falling sand becomes a sand item
• Falling red sand becomes a red sand item

You keep the resources while avoiding large numbers of animated falling entities.

---

📍 Cleanup Radius

The mod searches for matching falling blocks within a radius of:

96 blocks

around players who have disabled sand, gravel, or both.

Only the selected falling block types are removed.

For example:

• Gravel disabled + sand allowed = only gravel is cleaned
• Sand disabled + gravel allowed = only sand and red sand are cleaned
• Both disabled = all supported falling blocks are cleaned
• Both allowed = nothing is removed

---

👤 Per-Player Settings

Each player controls their own cleanup settings.

When you disable falling sand or gravel:

• The setting only applies around your player
• Other players do not automatically receive the same setting
• The server stores your selection using your player UUID

This makes the mod useful on multiplayer servers where different players may want different behavior.

---

🔄 Setting Resets

The settings are temporary server-session settings.

• When a player disconnects, their saved selection is removed
• When the server restarts, all settings return to Allowed

Players can simply press H again after reconnecting if they want to disable falling blocks.

⚙️ How It Works

The mod uses a simple client-server system:

1. Press H to open the GUI.
2. Select whether falling sand or gravel should be allowed or disabled.
3. The client sends your selection to the server.
4. The server stores the selection using your UUID.
5. During server ticks, the mod checks players with cleanup enabled.
6. Matching falling block entities within 96 blocks are detected.
7. The corresponding item is dropped.
8. The falling entity is removed.

All important entity removal is handled by the server.

⚠️ Important Behavior

Falling Blocks FPS Fix does not prevent sand or gravel from starting to fall.

Instead, it removes the falling entity after it appears and enters your cleanup radius.

This is intentional.

Because the falling block already exists, the mod can replace it with the correct item drop before removing the moving entity.

The result is:

• ✅ You keep the dropped block
• ✅ Large amounts of falling entities are cleaned up
• ✅ Fewer animated entities remain active
• ✅ Sand and gravel are less likely to destroy your FPS
• ❌ The falling block will not automatically turn back into a placed block
