Question 1

How do I port my existing SFML game to the Nintendo Switch using is::Engine?

Accepted Answer

Follow the Switch installation guide: install devkitPro, move source files to the cpp folder root, run copy_assets.cmd, and compile with make. The engine translates SFML calls to SDL 2 for Switch compatibility, but note that some SFML features like Render Texture are unsupported.

Question 2

is::Engine vs Godot for 2D game development – which is better?

Accepted Answer

is::Engine is ideal for C++ purists targeting niche platforms like Switch with SFML code, but lacks Godot's visual editor and larger community. Choose is::Engine for low-level control and multi-library support; opt for Godot if you prefer a more integrated, beginner-friendly environment with scripting languages.

Question 3

How to add new C++ source files in is::Engine for Android or CMake builds?

Accepted Answer

You must manually include .cpp files in the app_src.cmake or isengine.cmake files located in the cmake folder, as specified in the README. This step is error-prone and required for each new file to ensure the build system detects them.

Question 4

Does is::Engine support 3D graphics or is it only for 2D?

Accepted Answer

It's primarily a 2D framework, leveraging SFML 2 and SDL 2 for 2D rendering. There's no mention of 3D support; for 3D games, consider engines like Unreal or Ogre3D instead.

Question 5

What's the performance impact of running SFML on SDL 2 in is::Engine?

Accepted Answer

The engine adds a translation layer that may introduce minor overhead, but it enables cross-platform exports. Performance is generally suitable for 2D games, though complex scenes might benefit from native SDL 2 or pure SFML builds for optimization.

Question 6

Can I use is::Engine for commercial game projects?

Accepted Answer

Yes, it's open-source and allows commercial use, but ensure compliance with licenses for SFML, SDL 2, and other dependencies. The README includes examples of published games like 'I Can Transform', demonstrating real-world applicability.
