update loop

Forecasters say a coastal nor'easter could stall or loop off the New Jersey shore, prolonging winds and coastal rain. However, the threat of significant flooding has decreased as the storm's expected impact has weakened. Residents along the Jersey Shore are watching updated forecasts closely to see how long the slow-moving system will linger and whether conditions could still deteriorate before it finally moves away.

The fourth instalment in a physics programming series is out, this time focusing on the physics update loop — the core step in game engines where forces, collisions and movement are advanced at a fixed rate. It continues a series that has been walking developers through the basics of simulating physics in their own code.
