A Static Arcade Physics Body.

A Static Body never moves, and isn't automatically synchronized with its parent Game Object. That means if you make any change to the parent's origin, position, or scale after creating or adding the body, you'll need to update the Static Body manually.

A Static Body can collide with other Bodies, but is never moved by collisions.

Its dynamic counterpart is Phaser.Physics.Arcade.Body.

Constructor:

new StaticBody(world, gameObject)

Parameters:

name type description
world Phaser.Physics.Arcade.World

The Arcade Physics simulation this Static Body belongs to.

gameObject Phaser.GameObjects.GameObject

The Game Object this Static Body belongs to.
