eli5: the differences in game engines like Unreal Engine, etc?

256 views

There’s unreal engine, fox engine, enfusion engine, Frost Bite just to name a few off the top of my head. What makes them different? Why can’t there be a single unifying engine?

I understand the part about licensing and costs, but beyond that is there really any difference and if so, what is it?

When writing a computer program you have to do a lot of repetitive tasks – like turning on a specific pixel, or reading when the mouse moves or a key is pressed. Instead of writing this out every time, programmers create a shortcut, so they can just tell the program to run the “check for input” routine. Put a lot of those routines together, and you get a library of routines.

These “Engines” are simply programmer’s shortcut libraries. Instead of having to write out all the code to put a character in a spot on the screen and fill in the background, they can use unreal’s engine to put a character somewhere without having to deal with overlaps, collisions, etc – because all of those things are already in the routine.
