What is Delta?

Hi guys,

This may sound ignorant or childish, but I would like to know what it is exactly meant by “Delta”.

For example, in “Event tick”, we have “Delta second”, in “AddActorLocal/WorldOffset” we have “Delta Location”, in all the “Interp” options we have “Delta time”.

What is truly meant by Delta? Does it mean different things in different context?


It means difference, if I remember correctly. In Event Tick, Delta time is the difference in time since the last tick.

So if the delta is 0.5 seconds the last tick event occurred half a second ago :slight_smile:
