Then, in your Layout’s event sheet, include only the event sheets you really need.
Naming convention: always start your sheets with a lowercase e (e.g., eControls, eSounds, eInventory) so they are easy to spot.
2. Open for extension, closed for modification
Do not duplicate code! Avoid copy-pasting blocks of events.
Instead, prepare your events to be reusable.
Use generic functions: TakeDamage(target, value), SaveProgress(), playSound(), etc.
Take advantage of families: adding an enemy to Family_Enemies automatically gives it the same variables and rules.
3. Use families and groups smartly
For example, all of your enemies belong to Family_Enemies.
The player handles collisions with this family without worrying about the exact type (Zombie, Alien, Robot...). It’s the variables assigned to the family that manage the differences:
Damage, health points, speed, etc.
Event groups also allow you to enable/disable certain behaviors (stunned, boosted, menu open, etc.).
4. Organize and name your files properly
Recommended structure:
├── Object type/
│ ├── Debug/ (All debug tools, always good to have some text displayed on screen)
│ ├── Sprites/
│ │ ├── Background/
│ │ └── Enemies/
│ │ └── Land/
│ │ └── Player/
│ │ └── Props/
│ │ └── UI/
│ ├── System/ (keyboard, mouse, etc. go here)
│ └── Dictionaries & Array/
├── Sounds/
├── EventSheets/
│ ├── ePlayer
│ ├── eEnemies
│ ├── eUI
│ ├── eFunctions
│ └── eMain
Naming convention for sprites:
Always keep a common root (family) then specify:
[i]PlayerSprite, PlayerCollision, PlayerWeapon[/i]
[i]EnemyZombieSprite, EnemyAlienSprite[/i]
[i]UIHealthBar, UIScoreText[/i]
Result: more consistency and super-fast navigation with search and filters.
5. Optimize your sprites
If you have many similar sprites (like trees), prefer creating multiple animations inside a single sprite instead of multiplying separate sprites.
Conclusion
Even though Construct 3 cannot apply SOLID in the strict sense, you can still adopt its philosophy:
Clear organization (event sheets, folders, naming conventions)
Reusable code (families, generic functions)
Optimized and scalable project (sprites, groups, folder structure)
The result: your Construct projects become more professional, modular, and maintainable.
And remember: there’s never just one way to do things. :)
