Hi,

I am looking for a way to only detect 1 keyPress, instead of repeating ones, I guess it has to do with logic, but I can't to think that logically, anyone any tips?

here's the very basic code I'm using:

color[] colors={#FF0000,#FF6205,#FFAB01,#FDDF00,#FFFF00,#90F900,#00B511,#00D3FD,#0035FD,
#2B00B3,#6E00CC,#E100E6};
color c=colors[0];
 int index=0;

void setup(){
 size(400,400);
 noStroke();
 background(255);
}

void draw(){
   background(255);
   for(int i=0;i<colors.length;i++){
     fill(colors[i]);
     rect(i*20,0,20,20);
 }
 fill(c);
 rectMode(CENTER);
 rect(width/2,height/2, 100,100);
 danceMat();
}

void danceMat(){

 c=colors[index];
 if(keyPressed){
   if(key==CODED){
     if(keyCode==RIGHT){
       if(index<colors.length-1){
         index = index+1;
       }
     }else if(keyCode==LEFT){
       if(index>0){
         index -= 1;
       }
     }
   }
   print(index+"\n");
 }
}
