Step 3: Generate a Random Speed

If X Speed value is ever equal to 0, then it will be replaced with a random value. This means we can either assign a speed when we create the Enemy, or we can leave it undefined and have a value generated at random.

• X Speed of = 0

• : Set X Speed to 0.75+(Random(6)/10.0)

Random() is an MMF2 expression which generates random numbers. Random(x) will generate a random number between 0 and x-1. For example: Random(6) will generate a random number between 0 and 5.

However, we want a number much smaller than that, so we divide by 10 and the random value is now between 0 and 0.5. Then by adding 0.75, the final result is somewhere between 0.75 and 1.25.
