hello,
I never seem to understand how the mills() function works, I am working on the variation simple stimulus assignment now and the time only continues counting if I keep pressing space, where should I put my initial time? the square is supposed to change colors every multiple of 5
int r;
int time;
int m;
int startTime;
void setup() {
size(800, 800);
textSize(46);
text("Press SPACE to begin", 180, 200);
textSize(32);
text("Instructions:", 100, 600);
text("When the square becomes blue, press B", 100, 650);
text("When the square becomes red, press R", 100, 700);
}
void draw() {
time = millis() - startTime;
}
void keyPressed() {
if (key == ' ') {
text("time" + (time), 100, 200);
r = int(random(0, 2)); // selects a number between 1 and 2
startTime = millis();
startExperiment();
}
}
void startExperiment() {
m = millis() - time;
background(255, 255, 255);
fill(0);
rectMode(CENTER);
rect(400, 400, 400, 300);
if (m % 5 == 0) {
if (r == 0) {
fill(255, 0, 0);
rectMode(CENTER);
rect(400, 400, 400, 300);
}
if (r == 1) { // 1 makes the rectangle blue
fill(0, 0, 255);
rectMode(CENTER);
rect(400, 400, 400, 300);
}
}
}
