Hi @JohnUKresults

In this situation I would use 2 files 1 file to hold the race details (header) 1 to hold the laps or drivers (details) it makes the programming a bit more complicated but ultimately much more efficient.

Interesting I have found mouse control works quite well, the only issue I have seen like OldMoses is the need to add a short delay after actioning a click even to avoid duplicating the action.
What particular issues have you had?

Hi

When I did my version of a tile map editor in QB64 https://191brian.itch.io/qb64-tile-map-editor which is for image tiles rather than coloured blocks it uses the image file names in the map files rather than having to cross reference codes to files/image names. It outputs the maps as files instead of data statements.

Hi

Need a bit more info on what the application is. Do you want to add a new record or change one of the existing 4 records? If changing an existing record while sharing the file with other users could be messy, really need a db with record locking. I haven't tested it but I assume while one user has the file open on one else can open it.

Re com might help if you could share a snippet of your code. If you print to com it adds LF CR characters.

Hi

It is reading the data into the variable BLOCK% and if it is less than 9 it writes the value into the map array, the 9 in the data indicates the start position of the player which is set in the else part 
ELSE
      You(0) = col%
      You(1) = row%

IF Map(You(0), You(1) - 1) = 0 is testing if the cell the player is trying to move to is an empty (0) i.e not a wall (1) note this if statement changes depending on which direction the player is trying to move.

Hi

Found an Arduino in my shed, put a primitive sketch on it that listens for commands "fast", "med" and "slow" on the serial port then flashes its on board LED accordingly, then wrote a little QB64 program to send commands via serial port.
As proof of concept it works.



Arduino sketch.
String inputString ="";
int fspeed = 500;
char code = "x";

void setup() {
  pinMode(LED_BUILTIN, OUTPUT);
  Serial.begin(9600);

}

void loop() {
  // put your main code here, to run repeatedly:
  //Serial.println(code);
  digitalWrite(LED_BUILTIN, HIGH);
  delay(fspeed);
  digitalWrite(LED_BUILTIN,LOW);
  delay(fspeed);
}

void serialEvent()
{
  while(Serial.available())
  {
    char ch = (char)Serial.read();
    Serial.write(ch);
    inputString += ch;
    if(ch == '\n')
    {
      if(inputString == "fast\r\n"){
        fspeed = 50;
        code = "s";
      }
      if(inputString == "slow\r\n"){
        fspeed = 1000;
        code ="f";
      }
      if(inputString == "med\r\n"){
        fspeed = 500;
        code ="f";
      }
      inputString ="";
     
    }
  }
}
