How can I create an ui select button onclicked move actor from TilemapA to TilemapB?

I made an actor named Port

Widget for the UI
Space for the overlap to see the UI

I want the character to enter the overlap and display the UI, then select different buttons by clicking the mouse to transfer the character to the specified Tilemap。

I tried it myself for over ten hours, but the first problem was that the mouse couldn’t interact with the button at all. The second issue is that the mouse cannot click.

I hope some great god can guide me. Please .

Are you sure you enabled mouse input? Mouse cursor you see may be from editor.
Watch some tutorial about umg and mouse input (it is just few nodes to enable mouse).

Or:

  • make HUD blueprint
  • in that bp print message that you clicked mouse

Then you know if mouse for game is enabled.

Or:

  • get inside button blueprint
  • add hoover over event and click event
  • print on booth when they happen

Because button will not work (will not receive events) if something else is covering it. Only most top widget gets clicked and mouse over events.

Thank you for your reply.
Very Helpful.
