Weighted Random selection with dynamic adjustment with just 8 behaviors.

What is it good for?

Imagine you want waves of enemies, randomly spawned ...

... but you would like to start with more of the easy monsters in the beginning,
then as the level progresses, increase the frequency of tougher enemies.

Or simply define the type and frequency of enemies per level.

After messing about, the simplicity surprised me:

Make a table with enemies, adding the desired ratio each should appear. The order does not matter.

Now pick a random value from the sum of the ratios.

Then loop over the enemy table, subtracting each ratio from your random number until you reach 0 or less. The previous enemy is then the one to spawn.

Things are always 'simple' once you've worked out the answer.

Oh yeah, that was really obvious, I'm surprised you even had to work it out

@Hopscotch Snippets of brilliance like this inspire me with some great ideas that I would never attempt on my own without your tutelage. Once again, thank you.

@Socks Well, yeah, things always get lost in translation somewhere between my brain and mouth, I blame it on a sinus condition.

My pleasure @PhilipCC
