if you are using X and Y but want a radial deadzone this is what I figured out this morning (after I searched for the answer and found this post). The issue I ran into with doing the ABS > 0.5 of both sticks is that when using X and Y both it creates deadzones at the four corners while at full magnitude as well as deadzone at the center. The vector thing worked great and it’s a radial deadzone.
For direction (like facing or move angle) Make Vector from X and Y (Z=0), get vector length, if it’s > 0.5 process the input if not, do nothing (that works for angle)
For speed do the same thing, but if it is < 0.5 instead of doing nothing, set the value to 0 (you can also remap the vector length from 0-1 to 0.5 to 1 so you can have full speed control outside the deadzone).
