Beginner Topic 14 of 49 Graphics, Vision & Media

Game Loop

Repeating cycle of input, update and render.

How it works

The loop processes input, updates the world and renders each frame; fixed time-step updates give stable physics while rendering interpolates; vsync caps frame rate.

Where it is used

Game engines.

Common pitfall

Variable time steps cause non-deterministic physics.
