Try adding return false or return true (whichever would fit) to the end of your function, so there’s no way for input to get through without being handled.

@Josephyc

return isblocked;

This should be after the last }, outside of the if block.

[Josephyc]

what do you mean by that

[whileTRUEpass]

Look at my post, that will probably solve you problem in the way it was intended. Or so I hope.

[Josephyc]

I got the ancer

it turns out that all i had to do was put a

@Josephyc

return isblocked;

out side the if block becuase according to the stack overflow thing
" When the compiler looks at your code, it’s sees a third path (the else you didn’t code for) that could occur but doesn’t return a value. Hence not all code paths return a value.

For my suggested fix, I put a return after your loop ends. The other obvious spot - adding an else that had a return value to the if-else-if - would break the for loop."

C# compiler error: "not all code paths return a value"

that means that I had to put it out side the big if block like this:

public bool method(bool whaterver){
int  nub1 1;
int nub2 1;
if(nub1 == 1){
   bool whaterver = true;
}
return whatever = true;

[whileTRUEpass]

Which is what I suggested and what should have been marked as solution btw.
