Question

So I have a very simple game going here…, right now the AI is nearly perfect and I want it to make mistakes every now and then. The only way the player can win is if I slow the computer down to a mind numbingly easy level.

My logic is having a switch case statement like this:

int number = randomNumber

case 1:
computer moves the complete opposite way its supposed to
case 2:
computer moves the correct way

How can I have it select case 2 68% (random percentage, just an example) of the time, but still allow for some chance to make the computer fail? Is a switch case the right way to go? This way the difficulty and speed can stay high but the player can still win when the computer makes a mistake.

I’m on the iPhone. If there’s a better/different way, I’m open to it.

Answer 1

Generating Random Numbers in Objective-C

int randNumber = 1 + rand() % 100;

if( randNumber < 68 )
{
//68% path
}
else
{
//32% path
}
