How to Make a Platformer Game in MakeCode Arcade - Part 3

Introduction

• Focused on improving game aesthetics and adding complexity through multiple levels.

Adding Background

• Added a background image with mountains and clouds to enhance visual appeal.

Creating Levels

• Started with a single level; added functionality for multiple levels.
• Setting Sprite Start Position:
  • Used the tile map to designate a starting point (pink block).
  • Placed the hero sprite (Hopson Paw) on a random pink block.
  • Deleted the pink block after placing the sprite.
• Functions for Level Setup:
  • Encapsulated level setup code in a function called startLevel.
  • Used currentLevel variable to keep track of which level the player is on.
• Changing Levels:
  • Increased level counter on game over, called startLevel to set up the next level.

Designing Second Level

• Created a second level using existing tiles and increased width.
• Added coins and enemy flowers that spawn bees for added challenge.
• Implemented a portal for level completion and lava hazards.

Transitioning Between Levels

• Ensured that previous level’s enemies, flowers, and coins are removed when switching levels.
• Utilized loops to clean up sprites of specific kinds before starting a new level.

Creating Third Level with Wall Jumping

• Designed a tall vertical level for wall jumping mechanics.
• Wall Jumping Logic:
  • Set conditions for the hero to cling to walls when falling.
  • Adjusted Y-velocity to allow jumping and reapplying gravity.
  • Added visual for the hero when clinging to walls.

Fixing Visual Jitter

• Implemented conditions to prevent jitter when flipping images of the hero sprite.
• Adjusted image flipping criteria to include wall collisions.

Introducing Fireballs

• Added fireballs as a new hazard in the game.
• Created a visual for fireballs and programmed them to bob up and down.
• Implemented collision logic:
  • Player loses lives when overlapping with fireballs.

Game Testing

• Tested the game to ensure mechanics functioned correctly, including dodging bees and fireballs.

Hardware Integration

• Showed how to download the game to a handheld device (e.g., Meowbit) for portable play.
• Steps included connecting the device via USB and transferring the game file.

Conclusion

• Summary of enhancements made in this part: multiple levels, wall jumping, and fireballs.
• Encouragement to check links for more hardware options.
