- C++ β Used for advanced programming and performance-heavy tasks.
If you're new to programming, Blueprints are a great place to start!
Whatβs the difference between an Actor, a Pawn, and a Character?
- Actor: A basic object that can exist in the game world (e.g., lights, doors, cameras).
- Pawn: A type of Actor that can be possessed by a player or AI.
- Character: A Pawn with built-in movement mechanics like walking and jumping.
How do I fix common errors in Unreal Engine?
πΉ Packaging Failed Error β Can be caused by missing files or incorrect project settings. Check the Output Log for details and ensure you have the right SDKs installed.
πΉ Objects Falling Through the Floor β Make sure your object has a Collision Component and the correct collision settings.
πΉ Lighting Needs to Be Rebuilt Warning β Click "Build" in the toolbar to update the lighting. If the error persists, check that you have a Lightmass Importance Volume in your scene.
How do I make my first game?
- Start with a tutorial β Follow Unreal's beginner projects on Epic Games Learning.
- Learn Blueprints β Even if you plan to use C++, understanding Blueprints is useful.
- Build small projects β Start with something simple like a first-person prototype or a platformer.
- Experiment with free assets β The Unreal Marketplace offers free assets every month.
How do I optimize my Unreal game?
- Use Level Streaming β Load only parts of the world when needed.
- Optimize Lumen and Nanite β These are powerful but can be performance-heavy if not set up properly.
- Reduce Draw Calls β Use Hierarchical Instanced Static Meshes (HISM) when possible.
- Profile Performance β Use Unrealβs built-in profiler (
stat unit
,stat fps
,stat gpu
) to monitor performance.
