Is this possible??? (random numbers)

TDog3337

Is there a way to use increments using the random function??

For example, x = random(0,50) will give me a number between 0 and 50. What if I want it to give me either 0 or 50, but not the numbers in between??

GoToLoop

void setup() {
  frameRate(1);
}

void draw() {
  int x = random(1) < .5? 0 : 50;
  print(x, TAB);
}

I'm pretty new to programing, could you explain what this means?

If random (number between 0 and 1) is smaller than 0.5 then set x to 0 : otherwise set x to 50.

This:

int x = random(1) < .5? 0 : 50;

Can also be written like this:

if (random(1.0) < 0.5)
    x = 0.0;
else
    x = 50.0;

The random(1.0) will produce a number between 0.0 and 1.0 and there is about a 50% chance it will be less than 0.5. If it is less than 0.5 then x is assigned 0.0, otherwise it is assigned 50.0

@asimes, you've forgotten to declare variable x! :-\"

int x = random(1) < .5? 0 : 50;
print(x, TAB);

is equivalent to:

int x;

if (random(1) < .5)  x = 0;
else                 x = 50;

print(x, TAB);
