You could do something like this:

// generate a random float between 0.0 and 1.0 and compare its value to the percentage you would like doSomething() to be triggered if ( Std.rand2f(0.0, 1.0) < 0.20 ) { // the code in here has a 20% chance of executing doSomething(); }

This is likely what's going on behind the scenes in the coin method in SC.

Or, as a function for re-use; fun int coin(float x) { if (Std.rand2f(0,1)< x) return 1; else return 0; } //usage; <<>>; There is also the "maybe" keyword which is not as versatile but easier; it returns 1 or 0, with a 50/50 chance. Yours, Kas.
