Priority-based forces
When dealing with priorities, only certain forces are taken into account based on some sort
of priority or condition. For example, you can have a system that disregards all forces that
are smaller than some amount or allow a round-robin style of applying forces, letting each
force have a small fraction of time to apply the steering. Allowing a round robin approach
can fix issues that appear in a weighted sums approach where steering forces cancel each
other out and essentially leave the agent with no ability to move.
Neither the weighted sums nor the priority-based approach is perfect; both methods take a
good amount of work to finely tune the agents to their expected locomotion behaviors.
