If you got 'GreenfootSound( filename)' from the API, then you were looking at the constructor signature and you used it properly at the end of line 3. (World, Actor, GreenfootImage, Greenfoot and MouseInfo) / Write a description of class Digdug here. The argument 'filename' is not used in the method anywhere - so there is no need to have the argument at all. On my 3rd level i want it to play certain sounds and music at certain points when conditions are met in the world. Method names should give some indication as to what the method does the first word in the name should be a verb. Your expression to the right of the equal sign on line 3 looks good. Just by using the method play, it will play just one time there is no need to stop or pause it. Im working on a game program for school and there are multiple levels. Making a GreenfootSound object will allow the methods in its class to control the sound object. 'variableName' can be any name that follows the rules given at the bottom of this page. when i shoot a space invader and when i get shot it has a slight delay so you can actually see the damagedimage and also i think it gives it gives a retro vibe, one problem is that when my ufo goes atop of the screen it has a 12 second sound clip playing but the delay doesnt pause it so if i hit a. I believe the Greenfoot method playSound causes the sound to be looped automatically and there is no control over that sound once it is started. Triggering a sound on an event, in this case a.

MainMenu loads a song If my 'Play Button' actor is clicked I want the song to stop, my new world to load, and the current music to stop. VariableType variableName = expression_or_value Then you can start and stop the sound like this: sound.start() //start playing the sound sound. stop method will stop the sound but how can I call that method from my actor. Neither line 3 nor line 4 could possibly compile without an exception being thrown.Ī variable is assigned a value like as in the following (in pseudo-code): It is a version of the project that includes all the functionality we have discussed so far: worms, lobsters, keyboard control, and sound (Figure 3.4).That could not possibly compile. The limit is -20 This method returns a random number that can be any value from zero up to but not including the given limit (so from zero to limit-1)ģ Comparison Operators An example: if (5 > 1) Plays Sound Effectģ6 Playing the Game The little-crab-4 version of this scenario shows the solution to this. Check the 'controls' menu the shortcuts are listed there. Got confused because of the category (: (And to correct myself its Greenfoot.stop() not Greenfoot.pause()) davmac. Greenfoot.getRandomNumber(limit) This will give us a random number between 0 and 20. how to play and pause through keyboard shortcuts. Topics: random behavior, keyboard control, sound concepts: dot notation, random numbers, defining methods, comments We’ll use a Greenfoot Utility A Greenfoot utility is a method supplied by the Greenfoot environment, so the method starts with “Greenfoot.” in its name (“Dot-notation”).
