random integers....

I need to generate a random integer between 25 and 60 for a game I'm writing. I used a while loop to check randomly generated numbers untill I came up with one, but it seems like there must be an easier way to do this. Anyone have any if there is?

Try doing % 36 on your random number and adding 25 to it.

Try:

"Math.random()" will return random number between 0.0 and 1.0, exclusive. Multiplying by 36 will give you a number between 0.0 and 36.0. The cast turns that into an "int" between 0 and 35. Adding 25 to that will give you a value between 25 and 60, inclusive.
