How to define variable in play scala template

Question

I want to define this Java variable

int x = 0; 
x = x + 1;

How is it in Play Scala Template??

I already tried this for defining:

@import scala.Predef;
val x= 0

but I can't add the variable

If you dont want to use @defining, you could always do something like @var x=0; x=x+1 and later use variable x, which is the second answer in the linked question. — Johny T Koshy

Why don't you want to use @defining? Is it about having too many indentations? If so, I think you shouldn't worry, because you should not need this kind of variables so often. It would be only a few. If you need more, then most probably you need to break apart your template into small pieces. — Feyyaz

They should be on the same line

@import scala.Predef; val x= 0

Also, if it is a variable, you should use var not val.

So what you need is

@import scala.Predef; var x= 0

And for reassigning:

@(x = x + 1)
