Example 40 with DamageSource

/**
 * @author blood - May 12th, 2016
 * @author gabizou - June 4th, 2016 - Update for 1.9.4 and Cause Tracker changes
 *
 * @reason SpongeForge requires an overwrite so we do it here instead. This handles all living entity death events
 * (except players). Note should be taken that normally, there are lists for drops captured, however, the drops
 * are retroactively captured by the PhaseTracker and associated through the different phases, depending on
 * how they are handled, so no lists and flags on the entities themselves are needed as they are tracked through
 * the {@link PhaseContext} of the current {@link IPhaseState} at which this method is called. The compatibility
 * for Forge's events to throw are handled specially in SpongeForge.
