public ScoreCounter getScoreCounter() { return scoreCounter; } (This is from the world sub-class)

I have shown my current code above, the points system adding is working, when the player touches a point, the point gets removed and a point is added to the score, but the taking away function is not working. If you are wondering why I want to take away points, it is because you will always get maximum points otherwise, as there is nothing to destroy you. Adding the loss of points over times means that time and speed becomes a factor, so not only do you have to complete it with getting all the points, but also complete it quickly.

Don't you need to call the 'losingPoints' method from the act method for it to do anything?

How would I call it in my code and where would I put it.

The same way you call 'getPoints' and 'movement' from the act method!

how do I make it so that instead of losing a point every act, only lose a point every 60 acts (1second)

Add an int field to the class to count act cycles (by having it increment each act cycle); when it becomes 60, zero it and have plane lose health.

#
how would I code something to count act cycles, how do I add an int field, and to which class. Also to detect if it is 60 do I do (a guess) 
if(countActCycles = 60)
{
    score--;
    countActCycles = 0;
}

That is pretty close, kid. Line 1 should use '==' instead of '=' (you want to compare the values, not assign one to the other); and line 23 should call 'loseHealth', not decrement 'score' (which was not mentioned previously). You will also need to check for zero health after calling 'loseHealth' (it could become zero here also).

I do not have a health Bar, only score counter, that I want to go down every seccond

how do I make a countActCycles variable to count the cycles?
