how do you pick a random costume
Well... Strange question, but I suppose you would get a random number and if it is (x) then assign costume (x)
etc., etc., etc.
int costume = Greenfoot.getRandomNumber(the number of costumes you have);
if(costume==1)
{
setCostume(a costume);
}
if(costume==2)
{
setCostume(a costume)
}
Two remarks:
First, random numbers start with 0 (not 1). So for your first costume you have to compare to 0.
Second, you could save the sequence of if statements by using an array, and using the random number as an index into that array. For example:
String [] costumes = { "image1.png", "image2.png", "image3.png" );
...
int index = Greenfoot.getRandomNumber(costumes.length);
setImage(costumes[index]);
