Cara membuat game MIT App Inventor

Summary

In this tutorial video, the creator guides viewers through the process of creating a simple sporty game for mobile devices. The steps include setting up a new project, adding animations like a bouncing ball, and adjusting key elements such as the speed and behavior of the ball. The tutorial also covers programming functions for the ball's movement and bounce when it hits the screen edges. By the end, viewers will know how to test and run the game on an emulator or a mobile device, making it a beginner-friendly introduction to mobile game development.

Takeaways

• 😀 Start by creating a new project and giving it a name in your development environment.
• 😀 Ensure that the options 'Visible' and 'Status Bar' are checked so the title bar is hidden on Android.
• 😀 Add a canvas element to your project to serve as the background for the game.
• 😀 Customize the canvas color to your preference (e.g., light grey) to set the look of the game environment.
• 😀 Select and configure a 'Bold' element from the terminal animation library, and change its color to red.
• 😀 Set the diameter of the red element (e.g., a ball) to 20 pixels to adjust its size for visibility.
• 😀 Define a function that controls the speed of the bouncing element, setting it to a speed of 21 for smooth movement.
• 😀 Implement the bounce mechanism to make the element bounce off the screen edges when it touches them.
• 😀 Add a green color pattern to represent the bouncing object (like a ball) and set it as hidden initially.
• 😀 Copy-paste the logic to control the visibility and speed of the jumping element, displaying it when necessary.
• 😀 Test the game using an emulator to ensure that the gameplay and functionality work as expected.

Q & A

What is the main objective of the tutorial in the video?

The main objective is to teach viewers how to create a simple sporty game on Android, focusing on using drawing and animation tools.

What is the first step in creating the game project?

The first step is to create a new project, name it, and ensure that it is visible and has no status bar to remove the title when installed on Android.

Why is it important to disable the status bar in the game?

Disabling the status bar ensures that no title appears at the top of the game screen when the game is installed on an Android device.

What tool is used to design the visual elements of the game?

The video uses 'Drawing and Animation' to design the visual elements, with a canvas being added to the project to design the game interface.

What is the significance of setting the canvas size?

Setting the canvas size is crucial for defining the space where game elements like objects and animations will be displayed.

How is the color scheme customized for the game elements?

The color scheme is customized using color selection tools, where the background color is set to grey and certain elements like the ball are assigned specific colors such as red.

What is the role of the 'speed' variable in the game?

The 'speed' variable controls the jumping speed of the ball in the game, making it an important factor for adjusting the game's difficulty.

How is the ball's bounce functionality implemented?

The ball's bounce functionality is programmed to detect collisions with the screen edges, making the ball bounce back when it hits the boundaries of the screen.

What happens if the program is executed without proper speed or bounce settings?

Without proper speed or bounce settings, the ball's movement will not behave as expected, potentially making the game less interactive or unplayable.

What does the tutorial show after completing the programming part?

After completing the programming, the tutorial demonstrates how to test the game on an emulator to check if the game functions as expected before final installation.
