Is it possible to make behaviors frame dependent?

If you could disable delta time on behaviours, and you design your game around 60fps, then 2 problems would occur:

If the framerate goes below 60fps, then you will see the behaviours work in slow-motion.

If the framerate goes above 60fps (e.g. Someone uses a monitor or phone that supports 120hz), then you will see the behaviours speed up really fast.

There isn't much you can do to fix this, except by using delta time.

No, but you could recreate the behavior with events, and not use delta time. Usually you don't need the entire functionality of the built in behaviors.

For example, a simple bullet could just be move forward x pixels every tick.
