Dungeon Crawler

another lesson in react

the goal was to build a crawler game , and you got to design it however you would like no hits were given so i gotta say i like the challenge , Thought it was gonna be much harder , but got cough up in it and suddenly it was a working game with a bunch of levels and a challenging Boss at the end .

Play a bit and have fun =D at http://crawl.dalahest.se/

i think i have the code up on Codepen if your curious about how it was done. (link at the top of the page)

CSS Center

2017-02-07 19:39:59 CSS, HTML

1: Using Flexbox

<div class="center">
    <h1>I'm Centered!</h1>

Center everything within the div.

.center {
   display: flex; 		/* activate flexbox   */
   align-items: center; 	/* align vertically   */
   justify-content: center; 	/* align horizontally */

2: Using Table (Compatible Mode)

<div class="center">
    <div class="cell">
        <div class="content">
            <h1>I'm Centered!</h1>

Unlike flexbox, you will need three containers:

.center {
    display: table; 		/* .center acts like a table */

.cell {
    display: table-cell; 	/* make .cell act like a cell*/
    vertical-align: middle; 	/* align the cell middle */

.content {
    margin-left: auto; 		/* Center content */
    margin-right: auto; 	/* Center content */
    text-align: center; 	/* Center items */

CSS Flexbox Grid

2017-02-07 19:38:45 CSS, HTML, FLEXBOX

AweSome minimal css-flexbox-grid.

:root {
    --grid: {
        display: flex;
            flex-wrap: wrap;
    --cell: {
        box-sizing: border-box;
            flex-shrink: 0;


.Grid            { @apply --grid;  }
.Grid.\-top      { align-items: flex-start;  }
.Grid.\-middle   { align-items: center;  }
.Grid.\-bottom   { align-items: flex-end;  }

More php-oriented debugger with preg_* functions


Visualize ur RegEx

Looks crazy when https://regexper.com https://jex.im/regulex/

# Simple an ugly examples, 
# look for url that starts with ftp:// , http:// or https://
# 2 matches one on full url and second for name. 


# Notes ......

dont catch group (?:Blah)

[A-z] characterset 

{5} number of occurences {3,5} min-max

* 0 or More
+ 1 or More
? 0 or 1

^ NOT 

(?=Blah) positive lookahead spring tills du hittar Blah
(?!Blah) negative lookahead spring bara om ordet inte slutar på Blah

(?<=Blah) positive lookbehind matcha only if begins with
(?<!Blah) negative lookbehind matcha only if begins with

#ugly ex. again of lookbehind (php now)

$input = 'http://www.dalahest.se/';
preg_replace("/(?<=www\.)(.+)(?=\.)/i", "APA", $input);

Will result in -> 'http://www.APA.se/'


strstr         = match
stristr        = match case insensitive

preg_match     = regex match
preg_match_all = regex match with g-flag

explode        = split string to array 
preg_split     = split string to array with regEx

preg_grep      = filter through array and only return on regEx match


Oh well and just if you would like to check if a mail is valid .. here's the regEx for it .
