This works for detecting movement. Off an Event Tick you will need 2 Do Once nodes, a delay node (this sets how fast it “checks” the movement) 2 floats (FrozenX and FrozenY), a sequence, 1 boolean (Moving?) 2 branches, 2 equal equal nodes, 1 Get Actor Location node. 1 Print String (Optional).
This detects movement for X and Y, but probably can be easily tweaked to add Zed. I won’t mark this as solved yet…I will see if I can figure out how to tweak what I have here and work out something I can use for speed.
