I tried to make a demo with TopDownBP and many BP are not working

I used the template TopDownBP and many BP scipts are not working.

I tried to make a quit function after pressing esc that works on all other templates exept TopDownBP.

On the other projects I am using the Level BP space. In TopDownBP is not working anything that needs user input.

To be workable I made the Escape key to Quit command in TopDownController BP and only there work if you need to add a button pressed or mouse interaction.

Other problem is that I tried to use the “Unreal Engine 4 Tutorial - Manipulate Camera with mousewheel” and is not working again because that must be placed in top-down character BP as it requires mouse wheen interaction.

Can someone help on that ?
