One of the thing I\u2019ve had to do commonly over the years in making games is to be able to generate a random string. Now lot of times I do this on the server side of code to be able to generate a none, one time use code. But there are times where I have had to do it on the client side maybe to generate a password would be a common use of this, or it could be having to guess what the random letters are in a mastermind type of game. It’s a very simple thing to do.
\nAll we need to do is to define a set of letters or symbols characters for the program to pick from. We decide on a word length and then loop through that many times pick a random index from the length of the set and then concat a string with that.<\/p>\n

Here’s the outline of the code.<\/p>\n

\n
1. make a random string of letters
   \nvar letters = “ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789*#%&!”;<\/li>\n
2. we set up a variable called word set to blank
   \nvar word = “”;<\/li>\n
3. Pick a random place in the string
   \nvar index = Math.floor(Math.random() * letters.length);<\/li>\n
4. Concat the character at the place in the letters string to a string called word
   \nword += letters.charAt(index);<\/li>\n
5. Do that for the number of times that we want the word length to be
   \nvar wordLen = 10;
   \nfor (var i = 0; i < wordLen; i++) {}<\/li>\n
6. Return that value
   \nReturn word<\/li>\n<\/ol>\n

   Here is the full code<\/p>\n

   var StateMain = {\r\n    preload: function() {\r\n        game.load.image(\"button\", \"images\/btnGenerate.png\");\r\n    },\r\n    create: function() {\r\n        console.log(\"Ready!\");\r\n        var btnGet = game.add.sprite(game.world.centerX, game.world.centerY, \"button\");\r\n        this.text1 = game.add.text(game.world.centerX, game.height \/ 3, \"\");\r\n        this.text1.fill = \"#ffffff\";\r\n        btnGet.anchor.set(0.5, 0.5);\r\n        this.text1.anchor.set(0.5, 0.5);\r\n        btnGet.inputEnabled = true;\r\n        btnGet.events.onInputDown.add(this.getWord, this);\r\n    },\r\n    getWord: function() {\r\n        var word = this.makeRandomString();\r\n        this.text1.text = word;\r\n    },\r\n    makeRandomString: function() {\r\n        var letters = \"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789*#%&!\";\r\n        var word = \"\";\r\n       \r\n        var wordLen = 10;\r\n        for (var i = 0; i < wordLen; i++) {\r\n            var index = Math.floor(Math.random() * letters.length);\r\n            word += letters.charAt(index);\r\n        }\r\n        return word;\r\n    },\r\n    update: function() {}\r\n}<\/pre>\n
    <\/p>\n
   And Here is the result<\/p>\n
