Melon Editor Blockly – Door object and Level transition

The last chapter of Melon Editor’s Blockly series. This chapter will show you how to create new level and make transition object to move to that new level.

Welcome to Chapter 5 of our Melon Editor tutorial series! In this guide, we’ll show you how to create smooth level transitions in your game using object triggers and variables. Whether you’re making a platformer, puzzle game, or RPG, this method ensures seamless progression between levels.

Step 1: Setting Up the Level Transition System

1. Create a Door or Trigger Object
   • Design an object (e.g., a door, portal, or checkpoint) that players interact with to change levels.
   • Assign a collision type (e.g., “Level Trigger”) to detect player contact.
2. Add a Background (Optional)
   • Use a static or animated background to enhance the transition effect.

Step 2: Configuring the Transition Logic

1. Add a Variable for Level Tracking
   • Create a global variable (e.g., CurrentLevel) to track the player’s progress.
   • Example: CurrentLevel = 1 (for Level 1).
2. Set Up a Collision Event
   • When the player touches the door/trigger:
     • Deactivate the current level (to unload assets).
     • Load the next level using the TargetLevel variable.
   plaintextCopyDownloadOn Collision (Player & Door) → Set TargetLevel = CurrentLevel + 1 Load Level(TargetLevel)

Step 3: Smooth Transition Effects

1. Add a Fade-In/Fade-Out Animation
   • Use a black screen overlay or custom animation for polish.
   • Adjust transition speed for better gameplay flow.
2. Reset Player Controls (If Needed)
   • Disable player movement during loading.
   • Reactivate controls once the new level loads.

Step 4: Testing & Debugging

✅ Test the transition multiple times to ensure:

• No assets remain loaded from the previous level.
• The player spawns correctly in the new level.
• No bugs in collision detection.

🚨 Common Issues & Fixes:

• Level Doesn’t Load? → Check variable names and scene references.
• Player Stuck? → Verify spawn points in the new level.

Conclusion

By following these steps, you can create professional-level transitions in Melon Editor without complex coding. This system works for 2D platformers, adventure games, and more!

🔹 Pro Tip: Add sound effects (e.g., a “whoosh” for portals) for extra immersion.
