Vision Sensor Color Types

I want to loop through an array of my vision sensor colors, but auto doesn’t work. What type are they?

#2

Can you post what code you have now? The objects on the array are vision::object I think. I recommend extracting the desired value(centerX centerY etc) from the vision array and sticking it into a different array. I am currently attempting to make something similar right now for vision tracking the goal.

#3

Thank you. I don’t have my code right now, but I can post an idea. Do you use triple quotes for code?

Got it.

auto colors[2] = {BLUEY, REDY};
for (color : colors) {
    Vision.takeSnapshot(color);
    Brain.Screen.print(Vision.largestObject.originX);
    Brain.Screen.print(Vision.largestObject.originY);
}

Actually, it’s vision::signature.

vex::vision::signature colors[2] = {BLUEY, REDY};
  for (auto item : colors) {
    Vision.takeSnapshot(item);
    int x = Vision.largestObject.centerX;
    int y = Vision.largestObject.centerY;
    Controller1.Screen.print("x-value:");
    Controller1.Screen.print(x);
    Controller1.Screen.print(" y-value: ");
    Controller1.Screen.print(y);
  }
