# 
public void check(){
        if(getOneIntersectingObject(Scanner.class) != null && !checked){
            checked = true;
            System.out.println(Scanner.lastNum);
            if((input-Scanner.lastNum) < input&&Scanner.lastNum == Scanner.lastNum++){
                getWorld().addObject(new GameOver(), 405, 310);
                Greenfoot.stop();
            }
            Scanner.lastNum++;
        }
    }
This code is supposed to check for a scanner when it is in the correct order but it either just passes through or stops at the second block is there an easier way

I don't understand what your source code should do, but I can tell that the expression 
Scanner.lastNum == Scanner.lastNum++
is wrong. (and the expression 
(input-Scanner.lastNum) < input
can be simplified to 
Scanner.lastNum > 0
, which implies that it probably is not what you want it to be, too.) To understand your question, the following infos would be helpful: 1. What is variable "input"? 2. What is the meaning of variable "Scanner.lastNum"? 3. What does "is in the correct order" mean for a scanner? (And what is a scanner?) 4. Presumably, seeing the source code of the complete class is necessary to solve the problem. 5. Very likely the variable "Scanner.lastNum" should instead be a private attribute of this class (except if it is used in other places, too, in which case the source code of Scanner would be needed, too, to solve the problem).
