Making Apps With Mit App Inventor

App Inventor 让您可以使用 Web 浏览器和连接的手机或模拟器为手机开发应用程序。App Inventor 服务器存储您的工作并帮助您跟踪项目。您可以通过以下方式构建应用程序：App Inventor Designer，您可以在其中为应用程序选择组件。本课程侧重于基于块的编码的使用。课程结构如下：在本课程中，您将了解应用程序，它们可以做什么，以及它们的发展简史。您还将设置模拟器并设置帐户。接下来，将向您介绍设计器和块编辑器，并学习添加文本和图像。然后您将使用这些知识来完成颜色按钮活动。然后您将学习设置屏幕属性、添加画布和使用 when 语句。

这将以创建一个带有弹跳球的应用程序结束。接下来，您将了解布局、如何上传媒体文件以及如何使用过程代码块。您将使用这些知识来创建钢琴应用程序。您将创建的下一个项目将是 Find The Gold 应用程序。在这个项目中，您将了解图像精灵组件、笛卡尔坐标系、If/If-then-else 块、通知器和不同显示器上的分辨率。下一个项目将是 Food Chase Game。这个项目将教你如何使用 If 语句进行碰撞、变量和用于高分的小型数据库。倒数第二个项目将是瓢虫追逐游戏。这个项目将教你在应用发明者中使用许多不同的游戏机制。这些是能量水平，游戏结束，重新开始游戏和声音效果。最后，您将创建 Quizlet 应用程序。该项目将向您介绍列表、遍历问题、切换图像和检查用户数据。

Description

App Inventor lets you develop applications for phones using a web browser and either the connected phone or emulator. The App Inventor servers store your work and help you keep track of your projects. You build apps by working with: The App Inventor Designer, where you select the components for your app. This course focuses on the use of block-based coding.The course is structured in the following way:In this course, you will be introduced to apps, what they can do, and a brief history of their development. You will also set up the emulator and set up an account.Next, you will be introduced to the designer and block editor, and learn to add text and images. Then you will use this knowledge to complete the colour button activity.You will then learn to set screen properties, add a canvas, and utilize when-statements.

This will conclude with the creation of an app with a bouncing ball.Next, you will learn about layout, how to upload media files, and how to use procedure code blocks. You will use this knowledge to create a piano app.The next project you will create will be the Find The Gold app. In this project you will learn about image sprite components, the cartesian coordinate system, If/If-then-else blocks, notifiers, and resolution on different displays.The Next project will be the Food Chase Game. This project will teach you how to use If-statements for collision, variables, and a tiny database for high scores.The second-last project will be the ladybug chase game. This project will teach you to use many different game mechanics in the app inventor. These are energy levels, game-overs, restarting the game, and sound effects.Finally, you will create the Quizlet app. This project will introduce you to lists, iterating through questions, switching images, and checking the user’s data.
