Question is about how to create a make the box that the mouse points to be visible or to make the user notice the size and where to put it, the purpose of this is to create a system for creating objects of different sizes and which will occupy a specific space in the field, an example may be the Dragon City's creation system, which when you want to create a store or something that is hovering over the space it occupies when you move the mouse around the place.
my current code performs that function, but it does not make the table visible:
float floatMousePosX = Camera.main.ScreenToWorldPoint(Input.mousePosition).x;
int gridMousePosX = 10 * Mathf.RoundToInt(floatMousePosX/10);
I hope your support, thank you.
