Physics

Xenko simulates real-world physics such as gravity and collisions. This section explains how physics components work, how to add them to your project, and how to use them with scripts.

In this section

• Colliders: Create physics by adding collider components to entities
  • Static colliders: Colliders that don't move
  • Rigidbodies: Moving objects, affected by gravity and collisions
  • Kinematic rigidbodies: Physics objects controlled by scripts
  • Characters: Colliders for characters (such as player characters and NPCs)
  • Collider shapes: Define the shape of collider components
  • Triggers: Use triggers to detect passing objects
  • Constraints: Create appealing and realistic physics
• Raycasting: Trace intersecting objects
• Simulation: How Xenko controls physics

Tutorials

• Create a bouncing ball: Use the static collider and rigidbody components to create a ball bouncing on a floor
• Script a trigger: Create a trigger that doubles the size of a ball when the ball passes through it

Xenko uses the open-source Bullet Physics engine. For detailed information, see the Bullet User Manual.
