Hey, in my Little game the actor Spider changes his Image if canSee the Laser class. Then he should Count the Counter til 0 and then remove. But it says "Unreachable Statement". What is false??

setImage("Blut.png");
          bloodcounter = 100;
          return;
          if(bloodcounter > 0)
          {
              bloodcounter--;
          }
          else
          {
              remove(Spider.class);
              return;
          }
          setImage("Blut.png");
          return;

Thanks a lot

After the first return statement the method will break up. The return will always be executed and so the code that follows the return will never be executed. That causes this compiler error.

I think another problem will be in line 10. remove(Spiderl.class) will probably not work. You should use getWorld().removeObject(this); (after this statement you can use a return)

aaaah now i understand sry and thx. But another Problem: first i had the code to remove the Spider in the laser code. But then i dont want to remove it, but i want to Change the Image. So i made the code for the Spider class (canSee(Laser.class)) and now the Spiders cant be killed?! it seems like they never see the laser class...
