    I'm fairly new to Unity and I would like to know if there is a way to create an interactive 2D world map in Unity. I need to have a map with clickable regions and that I will be able to zoom onto different regions. Can anyone help?

    It's easiest with sprites. Map background, region sprites + highlighted versions. Move the camera to centre on the region in question as needed, and change orthographic size to zoom.

    One common trick for irregular shaped regions is to have another texture in plain colours that you can read the pixels off to determine the country selected.

    How are you going to detect the region you have selected? with raycast hit?

    Raycast doesn't often make sense for a 2D map. Instead you can translate the screen position to a world position directly.
