VEX V5 vision code class

Hi

I’m trying to understand the “code” class in VEXcode’s vision class. You can create a code object that takes a list of signatures, then use takeSnapShot with the code object as an argument. My question is, how is this code used by takeSnapShot?

Having runs some experiments, it does NOT cause the program to look for objects of any color listed in the code object. Presumably it is combining the signatures in some way.

Thanks!

The code class is used for detecting two (or more) adjacent signatures (basically colors), for example, red next to green, or blue next to yellow. See this

Vision sensor setup

and here is how to set a color code using two signatures. pretty much the same code used. int main() { // Draw an area representing the vision sensor field of view Brain.Screen.clearScreen( vex::color::black ); Brain.Screen.setPenColor( vex::color::green ); Brain.Screen.drawRectangle( screen_origin_x-1, screen_origin_y-1, screen_width+2, screen_height+2 ); while(1) { // request any objects with color code C1 int numberObjects = Vision1.takeSnapshot( C1…

Interesting… Thanks!
