very basic controlp5 problem

hi all
after along struggle ive managed to cobble this code together merged from various sketches

it runs but I would like to improve it

im sure its very messy so some advice cleaning it up would be a help.

I ve had to comment out the all the code relating to the COG ARROW as the time slider is some how locked

to the rotation of the arrow

the slider allows me to pause the play of track and see current speed and lat,long time etc

but I have not worked out if or how to reverse the play any pointers with this would also be a great help

heres the code and sample gps text file
import controlP5.*;

ControlP5 controlP5;

int time;

boolean playPause = true; // true = play, false = pause

boolean revPause = true; // true = rev, false = pause

void play() { playPause = !playPause; } // toggle

hi guys

any chance of some help with this code its almost working but not quite right

the coordinates plot to screen, the slider has some functionality but doesn't scroll through the plot forwards backwards

our pause.The plotting only changes the colour of ellipse when pause is pushed and that is accidental

any pointers are appreciated

hi all
im trying to plot latitude ,longitude and display the the completed track but can only display the current position as the file is read . I believe i need to create an array list to store the positions before they can be permanently displayed

can somone offer some help with this.

many thanks

this is the code im running with a sample of the gps code at the bottom.

BufferedReader reader;

String line;

//-----------------------

float latitude =0.0;

String northSouth;

float longitude = 0.0;

String eastWest;

float heading = 0.0;

float speed =0.0;

int hrs,mins,secs;

int thisDay, thisMonth,thisYear;

//-----------------------------------

float x;

float y;

PImage raster;

void setup() {

size(1700, 700);

//-----------------

PFont myFont =createFont(PFont.list()[2],24);

textFont(myFont);

//-------------

ellipseMode(CENTER);

smooth();

frameRate(10);

// Open the file from the createWriter() example

reader = createReader("gprmc.txt");

}

background (0);

text("Lat " +" "+northSouth , 50,90);

text("heading "+ heading + "degrees",50,110);

// text(hrs+":"+mins+":"+secs +"GMT ",50,130);

//text("Lat " +" "+northSouth , 50,130);

// text("heading "+ heading + "degrees",50,150);

text("Speed M/Sec "+ speed ,50,170);

// drawArrow(heading);



try {

line = reader.readLine();

} catch (IOException e) {

e.printStackTrace();
