앱인벤터 폭탄게임 만들기

Summary

The video demonstrates how to build a simple bomb-roulette game in MIT App Inventor. Players press numbered buttons, and one button is secretly assigned as the bomb. Pressing it triggers an explosion image and sound, creating a party-game penalty mechanic.

Main Ideas and Build Process

• Find the game assets

  • Choose images for the unexploded bomb and its explosion.
  • Find a bomb sound effect and a button-click sound.
  • The presenter suggests using Pixabay to find and download sound effects, then uploading the selected files to App Inventor’s Media section.

• Design a screen that works on different phones

  • Screen dimensions vary, so many buttons may not fit in one row.
  • The presenter experiments with scrolling layouts and uses a vertical arrangement to let the screen scroll.
  • Buttons can be grouped in horizontal arrangements, with the bomb image displayed above or beside them.
  • The example uses ten numbered buttons, though a smaller game is also possible.
  • Add a title and Start and Reset buttons. Adjust the layout, button size, alignment, font, and colors to suit the screen.

• Use a variable to track the bomb

  • Create a global variable for the bomb’s position and initially set it to 0.
  • When Start is pressed, assign the variable a random integer corresponding to one of the numbered buttons. For the ten-button version, choose a number from 1 to 10.
  • When Reset is pressed, set the variable back to 0 and restore the original, unexploded bomb image.

• Program each numbered button

  • Give each button a number that matches its position.
  • When a button is pressed, play a click sound.
  • Compare the button’s number with the stored bomb number.
  • If the numbers match, change the bomb image to the explosion image and play the explosion sound.
  • Duplicate the button logic for the other buttons, updating the button and number in each copied block.

Key Lesson

The project illustrates how App Inventor combines visual layout, media assets, variables, random numbers, conditions, and event-based button actions to make a simple interactive game. The presenter encourages viewers to follow along, adjust the layout for their devices, and customize the button colors.
