Moving an object with hold & drag?

Question

Unity

Good day, help me cope with one task, how to move a 3D object along the x axis by holding and dragging with a finger on the screen or with the mouse?

Sorry for not being able to formulate the question correctly!

Answer 1

Assign a collider to an object and:

void OnMouseDrag() {
    Vector2 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition) ; 
    mousePos.y = 0f; // только по Х
    transform.position = mousePos ; 
}

For the drag, we catch it with the TouchPhase.Moved phase. And also set the coordinate.
