How do i change the zoom of my layout?

Okay so i have figured out how to make the layout bigger. I have made my layout bigger. The problem is that when i play the layout the whole layout is showed on screen at once, in other words it's zoomed out to max and everything get's tiny and you can't see what you are doing. I want to know how you can make you only see a small part of the layout and it needs to be a specific part so you see the playable character. I have tried adding the behavior Scroll to to the main character but i still doesn't see the part where the main character starts. Can anyone help me whit this? And don't insult me becuase i don't know much.

Try adding "Set Layout Scale" to the event sheet. I did this for my game to zoom everything out a bit since originally everything was too up close. I went from 1.0 to 0.5 to zoom out, perhaps if you did the opposite it should work to zoom in.
