A very simple example would be to fade out an SKSpriteNode. In Swift: let node = SKSpriteNode(imageNamed: "image") let action = SKAction.fadeOutWithDuration(1.0) node.runAction(action)

Sometimes it is necessary to do an action on repeat or in a sequence. This example will make the node fade in and out a total of 3 times. In Swift: let node = SKSpriteNode(imageNamed: "image") let actionFadeOut = SKAction.fadeOutWithDuration(1.0) let actionFadeIn = SKAction.fadeInWithD...

One helpful case is to have the action run a block of code. In Swift: let node = SKSpriteNode(imageNamed: "image") let actionBlock = SKAction.runBlock({ //Do what you want here if let gameScene = node.scene as? GameScene { gameScene.score += 5 } }) node.runActi...

One of most common use cases of Gitflow Initialize repo and define branches $ git flow init # if you use default setup, you'll define six types of branches: # # main branches (lives forever) # # 1. master: for production releases # 2. develop: for "next ...

Let us assume we have the following Series: >>> import pandas as pd >>> s = pd.Series([1, 4, 6, 3, 8, 7, 4, 5]) >>> s 0 1 1 4 2 6 3 3 4 8 5 7 6 4 7 5 dtype: int64 Followings are a few simple things which come handy when you are workin...

Pandas provides an effective way to apply a function to every element of a Series and get a new Series. Let us assume we have the following Series: >>> import pandas as pd >>> s = pd.Series([3, 7, 5, 8, 9, 1, 0, 4]) >>> s 0 3 1 7 2 5 3 8 4 9 5 1 ...

Sometimes it maybe useful to have multiple distinct indexes of a field with different Analyzers. You can use the multi-fields capability to do so. PUT my_index { "mappings": { "user": { "properties": { "name": { "type...

Tomcat's Host Manager application by default is located at http://localhost:8080/host-manager, but is not accessible until a user is given permission in the conf/tomcat-users.xml file. The file needs to have: A manager-gui role A user with this role For example: <tomcat-users> ......

Once you have access to the host-manager, the GUI will let you add a virtual host. Note: In Tomcat 7 and 8, adding a virtual host via the GUI does not write the vhost to config files. You will need to manually edit the server.xml file to have the vhost available after a restart. See http://tomc...

2.04 Bash treats some paths as special and can do some network communication by writing to /dev/{udp|tcp}/host/port. Bash cannot setup a listening server, but can initiate a connection, and for TCP can read the results at least. For example, to send a simple web request one could do: exec 3</...

A child theme is identified by WordPress when there is a directory (for example child-theme) inside /wp-content/themes/ with the following files: style.css This file must start with a comment template like this: /* Theme Name: Example Child Author: Me Author URI: https://example.com/ ...

The most common usage of a child theme is to override template parts. For example, a sidebar, if we have a theme with the following file at /themes/template/sidebar.php <?php /** * The sidebar containing the main widget area. * * @link https://developer.wordpress.org/themes/basics/templa...
