앱인벤터 - 복불복 폭탄게임 앱 만들기

Summary

The video demonstrates how to build a “luck of the draw” bomb game in MIT App Inventor. Each press of the bomb button adds a random amount to a running total. As the total reaches successive milestones, the bomb image changes. At the final stage, the app plays an explosion sound and vibrates. A retry button resets the game.

Design and assets

Create a screen with:

• A title label
• A large button displaying the bomb image
• A label showing the running total
• A retry button

Adjust the button’s size and remove its default text so the bomb image is clear. Import the bomb images (b1 through b5, PNG files) and a WAV sound effect.

The subtitles give inconsistent milestone values, but describe changing the bomb image at stages around 12, 22, 32, and 42.

Programming steps

1. Create a total variable

   • Make a variable to store the accumulated value.
   • Initialize it to 0.

2. Program the bomb button

   • When the button is clicked, generate a random integer from 1 to 5.
   • Add that number to the stored total.
   • Update the total label to show the new value.
   • Check the total against the game’s milestone values and change the bomb image as appropriate.

3. Add the final effects

   • At the final milestone, play the explosion sound.
   • Add a vibration effect to increase the sense of suspense. The instructor suggests adjusting the vibration setting if it does not work as expected.

4. Program the retry button

   • Reset the total to 0.
   • Restore the starting bomb image.
   • Clear or reset the displayed total.

5. Test and save

   • Connect a phone using AI Companion and test the game.
   • Check that the total increases, images change at the intended stages, and the sound and vibration work.
   • Save the project and, if needed, export it to the computer for sharing.

Other topics mentioned

The instructor briefly discusses recording and editing the computer screen with Bandicam and Bandicut. Near the end, the video also turns to binary numbers and suggests trying an online number game; this is separate from the bomb-game project.
