Rigid body

Meaning in game development, with examples

nounAdvanced term

In game development, rigid body means: An object in the physics engine that keeps its shape and is moved by forces such as gravity and collisions, for example a falling crate or a thrown grenade.

In Turkish: katı cisim, rigidbody

How it is used

Unity's component for it is called Rigidbody, written as one word. Developers add a rigid body to an object, set its mass and drag, and decide whether it is kinematic (moved by code) or simulated. Soft bodies, such as cloth, bend and change shape.

Example sentences

  1. Add a rigid body to the barrel so it rolls when the player kicks it.

  2. Too many active rigid bodies in one room made the physics step very slow.

Common collocations

  • add a rigid body
  • rigid body physics
  • kinematic rigid body
  • set the mass
  • physics engineThe system that simulates real-world physics in a game, such as gravity, collisions, friction and forces, so objects fall, bounce and push each other believably.
  • collision detectionThe part of a game that checks whether two objects touch or overlap, for example a bullet hitting an enemy or the player landing on a platform.
  • ragdollA physics setup in which a character's body becomes a set of connected parts that fall and react to forces realistically, usually when the character dies or is knocked down.
  • componentA piece of functionality attached to a game object, such as a collider, a light, an audio source or a script; an object's behavior comes from the components it has.
