Executing Logic n% of Time

[so1odo1o]

I want to implement some sort of "random" feel into my current AI and I need some help on executing logic n% of time. For example, I want my to follow the best path 80% of the time otherwise choose a random node to follow 20% of the time.

Any advice on how to execute logic n% of time possibly using the device time in a clever way?

Code: Select all

if(){ } // enter if statement 80% using time possibly

Well simple.

Code: Select all

srand(DeviceTime);
int percent = rand() % 100 + 1; //this generates a number between 1 and 100, without the +1 its just between 0 and 99

if (percent <= 80)
{
   //choose best pass
}
else
  //take random pass
