What does any of that have to do with the “mouse”? I don’t even see a node relating to the mouse there. That being said, make sure you have mouse input enabled on your controller. See the screen shot below for some places where you can play around with mouse input. Also if you want “mouse input” to simulate “touch” that is something you can tick in the project settings there is an option under the Input tab to “use mouse for touch”. Hope this helps.
