I am trying to be able to move a dummy left and right via the left and right arrow keys. I know that going left would be Vector3.new(-1, 0, 0) and going right would be Vector3.new(1, 0, 0), but I’ve tried many things that all don’t work.
I saw a similar post about moving a part via the WASD keys, and I tried a similar formula, except with using Humanoid:MoveTo(targetPosition), but in all it still did not move.
The Humanoid:MoveTo(targetPosition) moves to one point in the 3d game space. I believe you are concerned with direction of movement so have you tried dummyHumanoid:Move(direction)?
If dummyHumanoid:Move(direction) is used, according to documentation it will continue until it is given a new value. The simple solution here is to have a key state. If the A key is down, it goes left, and while its up, it overrights the direction to be 0. The similar concept would apply to the D key.
