Physgun and Gravity Gun

The physgun (purple)

Sandbox weapon #1. Left-click: grab and move. Scroll: push it farther or closer. Right-click: freeze it in the air.

Hold E while moving the mouse to rotate. Release E to move again.

• In Build, a PvP player cannot grab you or push your props.
• In PvP the physgun is not a shield: your props do not stop bullets like an anti-player fortress — build, do not hide behind a wall of palettes in a fight.
• R (reload) reloads / resets depending on the weapon, not the physgun.

The Gravity Gun (orange)

Left-click: throw. Right-click: pull. Less precise than the physgun, more fun for launching a crate. In Build it hurts nobody.

Freeze and unfreeze

A frozen prop (physgun right-click) stays in the air. An unfrozen one falls. For a house, freeze the walls. For a car that must roll, do not freeze the wheels.

Easy Weld / Weld on the Tool Gun welds two props: they move together.
