Question
Javascript/HTML
I'm making a yachtzee style program. Basically there is 6 dice (d0,d1,d2,d3,d4,d5) all held in an array called diceValues. When ever you click roll, the 6 dice randomly generate a number between 1 and 6 by calling the getRandomInt function (which works). However, whenever you roll the dice I have a function called rollDice() which is what puts values into the diceValue array for each dice as well as print off the 6 randomly generated dice. Another thing it does is heldValues which is started off as an array of false (heldValues = (false, false, false, false, false, false). When clicked upon, the certain dice thats clicked on is turned highlighted green and selected as held. What I also need to do is when ever a user clicks on any of the dice during the roll to "hold" the values, then whenever the user clicks roll, the dice that are held, stay the same value and the other dice randomly generate again.
Example:
diceValues = (0, 0, 0, 0 ,0, 0)
heldValues = (false, false, false, false, false, false)
user clicks roll - getrandomint creates 6 numbers
diceValues = (2, 4, 6, 1, 4, 1)
user clicks on d1, and d4 to be held
heldValues should change to = (false, true, false, false, true, false)
and whenever the user clicks roll again the 2 true values should stay the same
diceValues = (3, 4, 2, 5, 4, 6)
here's my sample code EVERYTHING WORKS BESIDES THE rollDice() function
