That may provide more info as to how to code what you want. change act in line 20 to started if you dont want to put it in the constructor You need a method to stop the music that you can call before you change the world. It might help if you show the code to one of your turn methods (maybe, the 'turnLeft' or 'turnRight' one). The playLoop method shouldnt be called every act cycle. So, it might be wise to have it the last statement in the method, or create and call a new method, so it is the last statement in the method. I find execution of the current method continues even after the statement given is executed. Try re-saving the sound file withouth them and try again. Greenfoot.stop() Actually, I just now was in consideration of this statement that I provided here. Try re-saving the sound file withouth them and try again. You only want one instance of the music, so you only want one Sounds object created.

Each is a separate instance and is not playing when created and therefore starts playing. This movement is all AI movement, without using any user input. There are probably information tags in the mp3 file that Greenfoot/Java does not like. I have eating.wav in my sounds directory, and it should play whenever my crab eats the worm. The problem was that each time you create a new Sounds object (every act cycle) you, in turn, create a new instance of the GreenfootSound object called music.

If not try left and if not that way, try right. its looping thru I have not added the controls yet. Use of started () and stopped () method in World to avoid music that plays forever. I could be totally wrong, but what I am getting from what you have previously stated is that you want your actor to move upward, if at all possible. Teaches: Use of GreenfootSound API to create and optimize music and sound effects. I think you will need to explain better how you want this actor to move, in general. Only one point will be looked at, not 'in both directions (+ and -)'.

If both offsets are negative numbers, then the point looked at will be to the upper-left of the actor, etc. If both offsets are positive numbers, then the point looked at will be to the lower-right of the center of your actor. That is, if your actor is at an x of 'actorX' and a y of 'actorY' and you look at offset 'offsetX' and 'offsetY', then the location which will be tested for the objects of the given class will be at an x of 'actorX+offsetX' and y of 'actorY+offsetY'. When using 'getOneObjectAtOffset', the first two int parameters are the offsets horizontally and vertically from the location at which the actor is at where objects of a class are looked for. I do not know if I explained wellMaybe this is the misunderstanding. in both directions (+ and -) i want to detect an object only in the negative X (the left of my actor) Pamsho wrote.i have understood that getOneObjectAtOffset detect an object on X and Y but.
