Entity falling distance is the distance the entity have fallen without reaching a block. It can be used to calculate different damage from falling, or activating an effect after a big fall. Retrieving the falling distance float distanceFell = entity.getFallingDistance(); Setting the falling ...

You can cancel a fall damage by using the EntityDamageEvent @EventHandler public void onEntityDamage(EntityDamageEvent e) { Entity tookDamage = e.getEntity(); DamageCause cause = e.getCause(); if (cause == DamageCause.FALL){ //Damage was caused by falling, cancel it e.setCancelled(t...

If you find that no matter what you put in your URL only your default page is loading, it might be that your server does not support the PATH_INFO variable needed to serve search-engine friendly URLs. As a first step, open your application/config/config.php file and look for the URI Protocol inform...

This helper is loaded using the following code: In Controller itself(* can repeat again and again*) $this->load->helper('captcha'); In config/autoload.php (Load only once) $autoload['helper'] = array('captcha');

Takes an array of information to generate the CAPTCHA as input and creates the image to your specifications, returning an array of associative data about the image. [array] ( 'image' => IMAGE TAG 'time' => TIMESTAMP (in microtime) 'word' => CAPTCHA WORD ) The "imag...

Once loaded you can generate a captcha like this: $vals = array( 'word' => 'Random word', 'img_path' => './captcha/', 'img_url' => 'http://example.com/captcha/', 'font_path' => './path/to/fonts/texb.ttf', 'img_width' => '150', 'img_height'...

Here is an example of usage with a database. On the page where the CAPTCHA will be shown you'll have something like this: $this->load->helper('captcha'); $vals = array( 'img_path' => './captcha/', 'img_url' => 'http://example.com/captcha/' ); $cap = create_captc...

Before Java 8, there was DateFormat and SimpleDateFormat classes in the package java.text and this legacy code will be continued to be used for sometime. But, Java 8 offers a modern approach to handling Formatting and Parsing. In formatting and parsing first you pass a String object to DateTimeFor...

It's a common request to be able to handle a double-click on a row in a RadGridView. The solution proposed by Telerik (http://demos.telerik.com/silverlight/#GridView/ClickEvents ) is based around code behind: this.grid.AddHandler(GridViewCellBase.CellDoubleClickEvent, new EventHandler<RadRouted...

Packages are collections of R functions, data, and compiled code in a well-defined format. Public (and private) repositories are used to host collections of R packages. The largest collection of R packages is available from CRAN. Some of the most popular R machine learning packages are the following...

from sklearn import svm X = [[1, 2], [3, 4]] #Training Samples y = [1, 2] #Class labels model = svm.SVC() #Making a support vector classifier model model.fit(X, y) #Fitting the data clf.predict([[2, 3]]) #After fitting, new data can be classified by using predict()

These three map functions are equivalent, so use the variation that your team finds most readable. val numberNames = Map(1 -> "One", 2 -> "Two", 3 -> "Three") // 1. No extraction numberNames.map(it => s"${it._1} is written ${it._2}" ) // 2....

Suppose we have an array: +-------+-----+-----+-----+-----+-----+-----+ | Index | 0 | 1 | 2 | 3 | 4 | 5 | +-------+-----+-----+-----+-----+-----+-----+ | Value | -1 | 3 | 4 | 0 | 2 | 1 | +-------+-----+-----+-----+-----+-----+-----+ We want to perform some query on thi...

Let's say, we have an array: Item = {-1, 0, 3, 6}. We want to construct SegmentTree array to find out the minimum value in a given range. Our segment tree will look like: The numbers below the nodes show the indices of each values that we'll store in our SegmentTree array. We can see that, to sto...

The procedure to perform a RMQ is already shown in introduction. The pseudo-code for checking Range Minimum Query will be: Procedure RangeMinimumQuery(SegmentTree, qLow, qHigh, low, high, position): if qLow <= low and qHigh >= high //Total Overlap Return SegmentTree[position] el...

Collection Operators can be used in a KVC key path to perform an operation on a “collection-type” property (i.e. NSArray, NSSet and similar). For example, a common operation to perform is to count the objects in a collection. To achieve this, you use the @count collection operator: self.array = @[@...
