Should I be using Event Ticks and Delta Seconds? And if not what can I use as a substitute?

Just because both answers here cover alternatives to Event Tick but don’t mention delta time specifically; if you use an Event Timer as an alternative to Event Tick to keep it framerate independent, you can use the node GetWorldDeltaSeconds instead of the delta seconds from Event Tick and you’ll get the same result.
