Self‑Closing Gate for Your FOB

This guide shows you how to create a self‑closing vehicle gate for your Forward Operating Base (FOB) in games like Squad. By combining partial gate destruction with strategic Hesco placement, you can force the game’s physics engine to automatically snap the gate shut whenever someone passes through—preventing teammates from accidentally leaving your base exposed.

You can see this exact mechanic demonstrated in the YouTube tutorial by @olFTvyWt4BA, but the full written breakdown is below.

How the Technique Works

Vehicle gates normally stay open until manually closed. However, when half of the gate is destroyed and the empty space is filled with solid structures, the remaining gate leaf detects a collision whenever it swings open. This causes the physics engine to override the “open” state and pull the gate shut automatically.

Step‑by‑Step Build Instructions

1. Place and Modify the Gate

Build a standard log or wooden wall gate at your FOB entrance.

Once it’s fully constructed, destroy exactly one half of the gate.

You should be left with a single swinging gate leaf still attached to the hinge.

2. Identify the Hinge Side

Look closely at which side the remaining gate leaf is attached to.

This hinge position determines where your Hesco blocks must go—your entire layout depends on this orientation.

3. Fill the Gap With a Tall Hesco Block Pair

On the opposite side of the hinge, place two tall Hesco blocks to fill the empty space where the destroyed half used to be.

These blocks must sit inside the original footprint of the gate so the physics engine recognizes them as an obstruction.

4. Build the Funnel Walls (Inside and Outside)

To stabilize the auto‑close behavior, you’ll create a mirrored funnel layout on both sides of the gate.

Inside the FOB

Starting from the edge of your newly placed Hesco block, build a small interior wall pattern:

3 blocks down

3 blocks across

1 block up

Outside the FOB

Mirror the exact same footprint on the exterior side:

3 blocks up

3 blocks across

1 block down

This symmetrical funnel ensures consistent collision detection from both directions.

Why This Works

With the destroyed gate half replaced by Hesco blocks and the funnel walls guiding movement, any player or vehicle passing through will push the remaining gate leaf into the Hesco collision zone.

The physics engine interprets this as an obstruction and automatically snaps the gate shut—creating a reliable, self‑closing entry point.
