I want to create a button based system

I am making a program on the brain and I want to create a button based system which will switch between cameras does anyone know how to do this? I tried using the Widget thing but, I don’t know how it works? I would appreciate a quick response since this project is due December 9th 2017.

Use “Set view target with blend” node. The following link will help you.

Use the level blueprint to get references to the camera actors in the level. Then you can switch between then using the above blueprint node.

You can also add functionality on button click to do the same.
