Craps Javascript Code
Craps code in Java. Below is the syntax highlighted version of Craps.java from §2.1 Static Methods. Craps is one of the only games in the casino where the player is in charge of the action with their own hand. You can literally grab the dice, give it a blow for good luck and roll it on down. In a single roll of the dice, there are a number of combinations in which a player can wager. I'm trying to make my code smaller and less verbose. The pass in the if statement are there because I need to check specifics on the dice roll. The code is running a game of craps where on the first roll if I get a 7 or 11 I win, or if I get a 2,3,12 I lose. Any other number I keep rolling till I either get what I rolled the first time or I.
Loops can execute a block of code as long as a specified condition is true.
Here's the 'plan' i'm doing with the craps program. I'm writing a big program that will simulate a casino, the 1st game I chose to make was craps, then blackjack and finaly a slot machine. The beggining of the big program will be 'Welcome to the casino, please type one of the following to play the game: Craps, Blackjack, or Slots.'
The While Loop
The while loop loops through a block of code as long as a specified condition is true.
Syntax
// code block to be executed
}
Example
In the following example, the code in the loop will run, over and over again, as long as a variable (i) is less than 10:
Example
text += 'The number is ' + i;
i++;
}
If you forget to increase the variable used in the condition, the loop will never end. This will crash your browser.
The Do/While Loop
The do/while loop is a variant of the while loop. This loop will execute the code block once, before checking if the condition is true, then it will repeat the loop as long as the condition is true.
Syntax
// code block to be executed
}
while (condition);
Example
The example below uses a do/while loop. The loop will always be executed at least once, even if the condition is false, because the code block is executed before the condition is tested:
Example
text += 'The number is ' + i;
i++;
}
while (i < 10);
Do not forget to increase the variable used in the condition, otherwise the loop will never end!
Comparing For and While
If you have read the previous chapter, about the for loop, you will discover that a while loop is much the same as a for loop, with statement 1 and statement 3 omitted.
The loop in this example uses a for loop to collect the car names from the cars array:
Craps Javascript
Example
var i = 0;
var text = ';
for (;cars[i];) {
text += cars[i] + '<br>';
i++;
}
The loop in this example uses a while loop to collect the car names from the cars array:
Example
var i = 0;
var text = ';
while (cars[i]) {
text += cars[i] + '<br>';
i++;
}
