hi @bs.17
-a- is that the spec of a homework assignment?
-b- please format your code
use the
</> menu button
and paste your code inside.
also i not understand your program flow
- global variables
- void setup(){}
- void draw(){}
for me it looks like you print from setup a declared but empty array??

thanks for getting back ive been struggling @kll . yes for my ap computer science principles class
–ok so you roll two dice and store them in a array(i named it diceRolls) its length shouldnt be longer then 36, void roll() is supposed to randomize dice 1 and dice 2 then put them in the array (length 36), then we were given a number mine was 12, program is supposed to go over that whole array and increase the variable sumNumber by 1 everytime 12 appears on that list

sorry, coding does not work that way.
you have 3 functions
void roll(){}
void sumCounter(){}
void winLoss(){}
and i can not see where they are called.
and that means you did not test them ( or not even write them? )
what is called by processing is the
void setup() {}
and that should run
( if you would not have that bad documentation line )
and prints a empty array.
basic of a dice is a random number ( 1 …6 )
so you study
https://processing.org/reference/random_.html
and make it a function for a single dice roll
with a print on the result
and call that from the setup(){}
function.

sorry again beginner so Im still trying to figure out everything. what do you mean by I didn’t call them? could you please be more specific and point out @kll
float dice1 = random(1,6);
float dice2 = random(1,6);
this 2 variables ( from the variable declaration )
would give you 2 fix float numbers from 1 … 5
that you not want.
int dice1,dice2;
void setup() {
dice1 = rollDice();
dice2 = rollDice();
println(dice1,dice2);
}
int rollDice() {
return (int)random(1,7);
}
start from this.

okay so now it prints the random values of dice 1 and dice 2, but my main question was how am I supposed to store them in the list? i tried doing diceRolls = dice1 + dice2 and shouldnt that store them? thing is though its not @kll
this is due tmrw night and kinda freaking out
did you read about the array? @glv linked you?
now you store the dice1 and dice2 values to array.
you have the roll function where you add the two numbers,
but store to array not work this way,
nevertheless you would not even find out until you
call the roll() after the println of our little randomtestprogram
I read about it but doesnt help much, it assigns variables to each place in the array. i cant determine my variables because they r random. i tried playing around with what the article said yet still no progress its still only doing println(dice1,dice2); and thats it every other thing is empty, this is my first time with arrays so the struggle is real ive been on this since 5est @kll
but that is what you need to do,
make int array ( not float - - unless you have a dice what show 3.54 )
and store the sum of 2 dice rolls into each ?cell?
show me the actual code where you combine a array (? for loop over index?)
with my above
rollDice()
function.
float sum = 12;
int i=1;
int sumNumber = 0;
int[] diceRolls = new int[36];
int tValue = (1/36);
int dice1,dice2;
int eValue;
void setup(){
dice1 = rollDice();
dice2 = rollDice();
println(dice1,dice2);
printArray(diceRolls);
print(sumNumber);
}
int rollDice() {
return (int)random(1,6);
}
void roll()
{
for (int diceRolls=0;diceRolls<=36;diceRolls++) {
diceRolls = dice1 + dice2;
}
}
void sumCounter()
{
for (int diceRolls=0;diceRolls<=36;diceRolls++) {
if (diceRolls == 12)
{
sumNumber = sumNumber + 1;
}
eValue = sumNumber/36;
}
}
//@kll
-a- you not copy my 5 line code?
you not read random(1,6) means 6 is EXCLUDED
-b- you not call the roll function?
so you not even see that it not works???
int dice1, dice2;
int[] diceRolls = new int[36];
void setup() {
roll();
}
int rollDice() {
return (int)random(1, 7);
}
void roll() {
for (int i =0; i < 36; i++) {
dice1 = rollDice();
dice2 = rollDice();
int sum = dice1 + dice2;
diceRolls[i] = sum;
println(i, dice1, dice2,"sum ", sum);
}
}
