Real-machine testing of the IOS Sprite Kit tutorial and the addition and presentation of scenes

<span id="Label3"></p>iOS Sprite Kit Tutorial Real-machine test and scene add and show iOS implement Real-machine test<p><p>Before you perform a real-machine test, you first need to make sure that your device is connected to your Mac (or mac virtual machine) and that the device is connected to your Mac (or mac virtual machine) at the start of section 1.9.1, and that the device is Registered. Open the created project, and in the Run button column, set the device that the program is running to the name of the real Machine. It is automatically loaded into the "choose device to run by program" item, as shown in 1.102. Click the Run button to see that the application is running on the real machine.</p></p><p class="a"><p class="a"></p></p><p class="a0" style="text-align: center;"><p class="a0" style="text-align: center;"><strong></strong></p></p><p class="a0" style="text-align: center;"><p class="a0" style="text-align: center;"><strong>Figure 1.102 Setting up the device</strong></p></p>The scene of the Sprite kit<p><p>When a player enters a game on a mobile device or on a computer, the content that appears on the screen is called a scene, as shown in 2.1. In the game, the scene is a level, or a game interface. Such a scene makes up a game. This chapter explains how to add, display, set, toggle, and scroll the SCENE.</p></p><p class="a" style="text-align: center;"><p class="a" style="text-align: center;"></p></p><p class="a0" style="text-align: center;"><p class="a0" style="text-align: center;"><strong>Figure 2.1 Field View</strong></p></p>Sprite Kit Add scene<p><p>In a game, one or more scenes may be composed, depending on the design requirements of the game to Decide. So how is the scene added? This is the problem that will be addressed in this Section. The steps to add a new scene are as Follows:</p></p><p><p><strong>(1</strong> <strong></strong> Click Xcode to bring up the Welcome to Xcode Dialog box.

This is what is going to be explained in this Section.</p></p><p class="4"><p class="4"><strong>1. Create a scene</strong></p></p><p><p>Creating a scene is also called instantiating an object. Since each scenario is based on the Skscene class, each scenario has a common method of instantiating the object, which has the following syntax:</p></p><p class="a1"><p class="a1"></p></p> <ul> <ul> <li>Init (size Size:cgsize)</li> </ul> </ul><p><p></p></p><p><p>Where size is the size of the scene Object.</p></p><p class="4"><p class="4"><strong>2. Display the scene</strong></p></p><p><p>When you create a scene, you run the program at this point, and the newly added scene cannot be Displayed. If you want to display a new scene, you need to use Presentscene (_ scene:skscene?). method, which is used to display a scene with the following syntax:</p></p><p class="a1"><p class="a1"></p></p> <ul> <ul> <li>Func presentscene (_ scene:skscene?)</li> </ul> </ul><p><p></p></p><p><p>Where _ scene is used to represent the scene that needs to be displayed.</p></p><p><p>"example 2-1" below will be based on project 2-1 and the new scene added will be displayed on the screen with the following steps:</p></p><p><p>Open the Gameviewcontroller.swift file and delete some of the code in the Gameviewcontroller.swift file. At this point the remaining code is as Follows:</p></p><p class="a1"><p class="a1"></p></p> <ul> <ul> <li>Import UIKit</li> <li>Import SpriteKit</li> <li>Class Gameviewcontroller:uiviewcontroller {</li> <li>Override Func Viewdidload () {</li> <li>Super.viewdidload ()</li> <li>}</li> <li></li> <li>}</li> </ul> </ul><p><p></p></p><p><p>Add the following code to the Viewdidload () method, and this code implements the ability to display the newly added scene on the screen:</p></p><p class="a1"><p class="a1"></p></p> <ul> <li><li>Override Func Viewdidload () {</li></li> <li><li>Super.viewdidload ()</li></li> <li><li>Let Skview = Self.view as Skview</li></li> <li><li>Determines whether the scene property of the Skview is empty</li></li> <li><li>if (skview.scene = = Nil) {</li></li> <li><li>Skview.showsfps=true</li></li> <li><li>Skview.showsnodecount=true</li></li> <li><li>let <strong>scene=newgamescene (size:skView.bounds.size) </strong>//create scene</li></li> <li><li><strong>Skview.presentscene (scene) </strong>//show Scene</li></li> <li><li>}</li></li> <li><li>}</li></li> </ul><p><p></p></p><p><p>When you run the program, you see the effect shown in 2.8.</p></p><p class="a"><p class="a"></p></p><p class="a0" style="text-align: center;"><p class="a0" style="text-align: center;"><strong></strong></p></p><p class="a0" style="text-align: center;"><p class="a0" style="text-align: center;"><strong>Figure 2.8 Running effect</strong></p></p><p class="a2"><p class="a2"><strong>note:</strong> The Skview class is a view that is designed to present the sprite Kit. In this class, you can render and manage a skscene. You can load multiple sprites in each scene and manage their behavior.</p></p><p class="a2"><p class="a2"><strong>This article is selected from:</strong>iOS game frame Sprite Kit Basic Tutorial--swift version of the University PA Internal information, reproduced Please indicate the source, respect the technology respect the IT person!</p></p><p><p>Real-machine testing of the IOS Sprite Kit tutorial and the addition and presentation of scenes</p></p></span>
