Hello, I need help for my greenfoot project! I want to remove 1 life from my figure if he can see an enemy but instead he instantly kills me. Here is my code: if (canSee(Gegner1.class) ) { leben=leben-1; }

You could have a boolean which indicates if an enemy "sees" the figure right now. Only subtract one life if it changes from 'false' to 'true'. 
private boolean gegnerDa = false;

//...
if (!gegnerDa && canSee(Gegner1.class))
{
    leben--;
    gegnerDa = true;
}
else if (gegnerDa && !canSee(Gegner1.class)) gegnerDa = false;
