Adding/Subtracting a int

**Alkor** · 03-09-2012, 03:36 AM

Okay, dumb question...

Java Code:

PlayerX --;

How could I get this to subtract lets say 5.

Thanks!

Use an assignment statement.

If i assign it then i cant add more to it later on...

use the -= operator, which is equivalent to
PlayerX = PlayerX - x;

so do

Java Code:

PlayerX -= 5;

You can add and subtract many times. That is why they are called variables.

Thanks jcarosella10, thats what i was looking for

**jcarosella10** · 03-09-2012, 04:30 AM

your welcome. That works for all the operations like +=, *=, /=

It is still an assignment statement.

I know. I don't think he knows though

@op, *=, +=, -=, /=, and %= are equivalent to

Java Code:

int x = 1;
x = x + 1;

In this snippet, I should +=, it should be obvious what the other ones look like.
