Using variables to easily change String or Int Array values?

hi there.  i'm coding button box sim racing uses 12-way rotary switch determine of various button values , messages output.

so example, if i'm on position 1, might want messages output buttons different if on position 2 or 3 etc...

my thought use array string variables , int variables , use string variables change message stored in array, , int variables change keyboard value depending on switch positions.

the message updates seem not happening , i'm trying figure out why not working.  been 15 years since did coding i'm rusty.  looking help.  thanks!

code: [select]


void setup() {
  //gameval , blkboxval store values of 12 way selectors
 
  //initialize 12 way black box dial messages
  string blkboxvalmsg1 = "";
  string blkboxvalmsg2 = "";
  string blkboxvalmsg3 = "";
  string blkboxvalmsg4 = "";

  //initialize array variables defined above 12 way black box dial
  string blkboxvalmsg[] = { "", blkboxvalmsg1, blkboxvalmsg2, blkboxvalmsg3, blkboxvalmsg4 };
 
  //initialize blackbox twelve way keys may or may not used output keyboard character game
  int blkboxchar1 = 0;
  int blkboxchar2 = 0;
  int blkboxchar3 = 0;
  int blkboxchar4 = 0;

  //initialize array blackbox keys may change values
  const int twelvewayblkboxkeys[] { 0, blkboxchar1, blkboxchar2, blkboxchar3, blkboxchar4 };
}

void loop()
{
  //code left out:  first check see if gameval or blkboxval have changed, if execute below code
 
  if (gameval == 1)  //change messages , set characters nothing
  {
    blkboxvalmsg1 = "adj  brake  bias";     blkboxvalmsg2 = "front  sway  bar";
    blkboxvalmsg3 = " rear  sway  bar";     blkboxvalmsg4 = " adj  seat  pos ";
 
    blkboxchar1 = 0;    blkboxchar2 = 0;    blkboxchar3 = 0;  blkboxchar4 = 0;
  }
 
  else if (gameval == 2)  //change messages , set characters f1-f4
  {
    blkboxvalmsg1 = "  lap   timing  ";     blkboxvalmsg2 = "    standings   ";
    blkboxvalmsg3 = "relative  timing";     blkboxvalmsg4 = " fuel  settings ";
 
    blkboxchar1 = 0xc2;    blkboxchar2 = 0xc3;    blkboxchar3 = 0xc4;  blkboxchar4 = 0xc5;
  }
 
  if (gameval == 1 && blkboxval == 1)
  {
    lcd.print(blkboxvalmsg[blkboxval]); 
  }
 
  else if (gameval == 2 && blkboxval == 1)  //different game, output different message , press key
  {
    lcd.print(blkboxvalmsg[blkboxval]);
    keyboard.press(twelvewayblkboxkeys[blkboxval]);
    delay(150);
    keyboard.release(twelvewayblkboxkeys[blkboxval]);
  }
}


seems have duplicated  local variables in setup - have global ones did not see either same name?

read variable scope

(its better post full sketch, more not issue looking in unsuspected part)
