Random directions, with no repeat.. (Bad Description)
- by Neurofluxation
Hey there, So I'm knocking together a random pattern generation thing.
My code so far:
int permutes = 100;
int y = 31;
int x = 63;
while (permutes > 0) {
int rndTurn = random(1, 4);
if (rndTurn == 1) { y = y - 1; } //go up
if (rndTurn == 2) { y = y + 1; } //go down
if (rndTurn == 3) { x = x - 1; } //go right
if (rndTurn == 4) { x = x + 1; } //go left
setP(x, y, 1);
delay(250);
}
My question is, how would I go about getting the code to not go back on itself?
e.g. The code says "Go Left" but the next loop through it says "Go Right", how can I stop this?
NOTE: setP turns a specific pixel on.
Cheers peoples!
