Hey,
short question:
Greenfoot.getRandomNumber(50) -> random number between 0 and 50.
but how can I 'create' a random number between 20 and 30?
so the minimum hast to be 20 and the maximum 30.
thank you =))

getRandomNumber
create this method in your code:
and call it like this:
1 2 3 4 5 | public int getRandomNumber(int start,int end){ int normal = Greenfoot.getRandomNumber(end-start+1); return normal+start;} |
1 | getRandomNumber(20,30); |
@MatheMagican good way to solve that. I always just write Greenfoot.getRandomNumber(number)+ohterNumber but this way is better.
But Moritz, you should be carefull with this:
Greenfoot.getRandomNumber(50) is a random number from 0 to 49. It'll never be 50. This could be very dificult to find if your programm doesn't work bekause of that.
@ Gevater_Tod .. yes I know that -- with 'between' I meant a random number from 0 to 49 =)) thank you anyway =)
Moritz, something I didn't mention is that my method could return 20 and it could return 30.
