DrawableEntity Class

Delta Engine Documentation

Drawable components like Entity2D or Entity3D will interpolate between update ticks. NextUpdateStarted marks the beginning of an update tick to copy interpolatable data, it can also be used to check if any data has changed since last time and if something needs updating. View code on GitHub
