creatix Posted March 10, 2014 Share Posted March 10, 2014 Hello! Im new here so I hope I posted in right section. I need help with a task I've been given, Make a php-based web application where you can play "Russian roulette" The web interface will use Ajax and call a php backend that contains the game logic. Make a simple interface where you can choose between 1-6 in a list / radio buttons and when you click on a button called "spin" so called php backend via Ajax, this shuffles out a number between 1-6 and compare with the selected century. Get a hit so the word "BOOM" appear in the web interface, otherwise the sentence "You made it" appear.

php_bad_boy Posted December 13, 2014 Share Posted December 13, 2014 Hey creatix, I would write a PHP code which uses a $_GET['variable'] to access the chamber number, and then compare this with a random number. Then finally echo the message 'BOOM' or 'You made it...'. Here's an example: $user_chamber = intval($_GET['my_chamber']); $bullet_pos = rand(1,6); if ($bullet_pos == $user_chamber) { echo "BOOM! (bullet was in chamber " . $bullet_pos . ")"; } else { echo "You made it bro :-) (bullet was in chamber " . $bullet_pos . ")"; } Then you've got to write the AJAX. It's a simple program so I would just go with an HTML file with an embedded JavaScript. Here's what I came up with. If you need more help have a look at this cool tutorial: http://www.w3schools.com/php/php_ajax_php.asp Notice the javascript function included in the head, it is called by the trigger button. The form contains a select element and a button element. I've chose the button element rather than a submit element because we don't want to reload the whole page, just update it using AJAX. <html> <head> <title>Russian roulette</title> <script> function pullTrigger(chamber) { if (window.XMLHttpRequest) { xmlhttp = new XMLHttpRequest(); } else { xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange = function() { if (xmlhttp.readyState == 4 && xmlhttp.status == 200) { document.getElementById("result").innerHTML = xmlhttp.responseText; } } xmlhttp.open("GET", "roulette.php?my_chamber=" + chamber, true); xmlhttp.send(); } </script> </head> <body> <div id="result">Let's play a little game...</div> <form> <select id="pistol"> <option value="1">First chamber</option> <option value="2">Second chamber</option> <option value="3">Third chamber</option> <option value="4">Forth chamber</option> <option value="5">Fifth chamber</option> <option value="6">Sixth chamber</option> </select> <input type="button" value="Pull the trigger" onclick="pullTrigger(document.getElementById('pistol').value)"> </form> </body> </html> Link to comment https://forums.phpfreaks.com/topic/286861-russian-roulette-game-phpajax/#findComment-1499529 Share on other sites More sharing options...
hansford Posted December 14, 2014 Share Posted December 14, 2014 Appears you already wrote the code. All you have to do now is implement it. <?php if (isset($_GET['my_chamber'])) { $user_chamber = intval($_GET['my_chamber']); $bullet_pos = rand(1,6); if ($bullet_pos == $user_chamber) { echo "BOOM! (bullet was in chamber " . $bullet_pos . ")"; } else { echo "You made it bro :-) (bullet was in chamber " . $bullet_pos . ")"; } } else { 'DANG! out of bullets. Time to reload'; } Link to comment https://forums.phpfreaks.com/topic/286861-russian-roulette-game-phpajax/#findComment-1499563 Share on other sites More sharing options...
