Detecting ball movement

[CloutBl0x (cloutblox)]

How could I easily detect if a ball is moving or stationary with a couple lines of a code?

Check if physics assembly is sleeping

There isn’t really anything exposed to developers to monitor the sleep state of physically-simulated assemblies (via Lua, that is. You can turn on settings in Studio to visualize these elements, but you can’t really interact with them). You’d instead likely need to implement logic that is similar to what the engine already uses to determine conditions that would satisfy a sleep state and anchor the part when that happens, such as an assembly’s velocity exhibiting a zero-to-very-low magnitude fo…

As mentioned in the reply above, there isn’t really a method you can use to check if a object is moving.
Heres how I’d go about checking if a object is moving.

local Ball = path.to.Ball;
local isMoving = false;

local lastPosition = Ball.Position;
while true do
    task.wait();
    if Ball.Position ~= lastPosition then 
        isMoving = true; 
    else 
        isMoving = false;
    end

    lastPosition = Ball.Position;
end

You could also use Part.Velocity. Idk if it’s depreceated if it is use AssemblyLinearVelocity.

Part:GetPropertyChangedSignal("Velocity"):Connect(function()
   if Part.Velocity ~= Vector3.new(0, 0, 0) then
      -- moving
   else
      -- not moving
   end
end
