A zero rotation is always to the right. Rotation increases as you go clockwise. To "face" upward, an object must be turned three quarters the way around clockwise (3/4 of 360, 360 being a full circle, is 270). So setting an actor's rotation to 270 will have it face, or point, upward.

Volume Up and Down Chp 10 Simple Mp3

By Seb_3, with 2 replies.
Last reply by danpost, over 4 years ago:

Problem 1: two instances of sound. Remove sound from PlayPauseButton class. Problem 2: unchecked argument for setVolume. Ensure value is in range 0 to 100, inclusive to avoid throwing IllegalArgumentException. Controlling the sound through the user is (or should be) a behavior of the object containing that sound. Make button classes basically empty of added code and have world (where sound is) check for clicks on these objects.

I am making a math game where I need to randomize the placement of the answers on a multiple choice. I don't want all the correct answers to be on a single box, and I want to create the problems and answers randomly.

Save true answer object in field. Shuffle answers and display them. Compare picked object with saved object to check for correctness.

If you do horizontal and vertical movement separately

Is there a better way to approach this problem?

Not really. It is the best way to allow movement along the walls of the house. If not done separately, you would need to test each way anyway after a collision to see which axis of movement caused the collision. There is no guess work if you do them separately to begin with.

How to change world using inheritance?

By Risen, with 10 replies.
Last reply by rocket770, over 4 years ago:

I really don't understand why you need a new method to change the world, it makes no difference and if anything, having an extra layer just makes in inconvenient if anything since it is causing problems? As for the sound, create a sound object where you can then pause or stop it before you exit the world. <Code Omitted> Start the sound using sound.play(); then you may pause it or stop it using <Code Omitted> or <Code Omitted>
