Hi, id like to make my bee object move towards my flower object roughly (going off course a little bit on the way) i have basic code to move the bee which is this:

    public Bee()
    {
    }
   
    public void flyAround()
    {
        //go forward
        move(1);
        //turn randomly
       if(Greenfoot.getRandomNumber(100) < 5)
        {
            turn(Greenfoot.getRandomNumber(20) - 15);
        }
        //if hit side, turn
       if(getX() <= 5 || getX() >= getWorld().getWidth() - 5)
        {
           turn(1); 
        }
        //if hit side, turn
       if(getY() <= 5 || getY() >= getWorld().getHeight() - 5)
        {
            turn(1);
        }
    }
}

I guess you could add another random turn with a greater chance and maybe a bit more turn to zero in on a flower. You would need to know which way to turn depending on where the flower is with respect to the bee.

You may want to look at my Zombie Shooter Demo scenario. The zombies, when in range, slowly turn toward the player. The mechanism might give you ideas on how to accomplish what you want, at least as far as knowing which way the bees should turn.

Hi, im reading through it to see how it works and im confused what the 'getQR' part is? This is in the chaser part on the line:

move(rate/8, getQR());

getQR is a method in the QActor class. I could (maybe should) have named it getQRotation). It returns a precision rotation value where getQR()/QVAL (automatically rounded down to an integer) gives the same value as the Actor class method getRotation would. The getQR method in the QActor class is documented; so, take a look. The move method is also in the QActor class (check it out, also). It takes the distance to move and the (precise) angle to move in and moves the actor with precision.

I have looked at it for a while now and still can't figure out how to make my bee move towards to flower. I'm completetly lost. Any tips on how to make it move towards a flower?

You need to show what you have tried so we have something to work off of.

Try something. You have already seen codes in the demo -- in the act method of the Chaser class. The only thing you might want to change is the amounts of change in turn and speed as the distance decreases between the two actors.
