I am writing a story but I am trying to indent the dialog because right now it looks like a chunk of text.

My text is

> 
> Then a figure under the box moved behind Professor to which John yelled “Professor! Watch out!” But due to his old age, he didn't hear him...
> 
> 
> 

Would I indent it like

> 
> Then a figure under the box moved behind Professor to which John yelled  
> 
>  “Professor! Watch out!”  
> 
>  But due to his old age, he didn't hear him...
> 
> 
> 

I tried researching but don't exactly get how to implement it into my story, also how else can I indent my story to make it look less like a big blob of text without having to introduce a new paragraph
