if I wanted to create a method named cannotMove, by using if atWorldEdge and canSee(crab.class). How would I go about this so that cannotMove returns true when one or the other is invoked?

Creating a method
Compare the code below with how you stated what you wanted to do.
1 2 3 4 | public boolean cannotMove(){ return (atWorldEdge() || canSee(crab.class));} |
alright one more question, i need the crab to turn to the left while moving. I've already created methods for turnLeft (which is turn -90), turnRight (which is turn 90), turnBack (and turn180), snd the cannotMove method you helped me with. I now need a changeDirecction method that naturally turns left while moving, if it cannot move, it turns right, if it still cannot move, it turns back, if it still cannot move it turns 17 degrees, how would i combone all these methods i have created to form one big method.
I cannot answer your questions at the moment. Will respond to them this evening, if someone else hasn't helped you by then. Best regards.
Would this work:
1 2 3 4 5 6 7 8 9 10 | private void changeDirection(){ turnLeft(); // now facing left if (!cannotMove) return; turnBack(); // turning from facing left to facing right if (!cannotMove) return; turnRight(); // turning from facing right to facing back if (!cannotMove) return; turn(17);} |
