* Decouple 3rd person camera from player movement Arrow keys now move the player relative to the camera direction instead of using tank controls. The camera stays static unless explicitly controlled via right-click drag, mouse wheel, or touch gestures. Adds a single hook in CalculateNewPosDir that lets the extension take over movement computation. The extension manages its own velocity smoothing, computes camera-relative directions from an absolute yaw, and writes nav controller velocities via friend class access.

Extract GetLocalYaw() and InitAbsoluteYaw() helpers to deduplicate repeated atan2 patterns. Simplify SetupCamera by passing DEFAULT_ORBIT_YAW directly. Move TURN_RATE constant to file scope.

Use SDL_SetWindowRelativeMouseMode to hide the cursor and freeze its position while the right mouse button is held in 3rd person camera mode.

LEGO Island, portable
Development Vlog | Contributing | Matrix | Forums | Patreon
This initiative is a portable version of LEGO Island (Version 1.1, English) based on the decompilation project. Our primary goal is to transform the codebase to achieve platform independence, thereby enhancing compatibility across various systems while preserving the original game's experience as faithfully as possible.
Please note: this project is primarily dedicated to achieving platform independence without altering the core gameplay or rewriting code for improvement's sake. While those are worthwhile objectives, they are not within the scope of this project. isle-portable offers support for light modding using extensions.
Status
| Platform | Status |
|---|---|
| Windows |  |
| Linux | |
| macOS | |
| Web | |
| Nintendo 3DS | |
| Xbox One | |
| iOS | |
| Android | |
| Playstation Vita | |
| Nintendo Switch | |
We are actively working to support more platforms. If you have experience with a particular platform, we encourage you to contribute to isle-portable. You can find a list of ongoing efforts in our Wiki.
Usage
An existing copy of LEGO Island is required to use this project.
As it stands, builds provided in the Releases tab are mainly for developers; as such, they may not work properly for all end-users. Work is currently ongoing to create workable release builds ready for gameplay and general use by end-users. If you are technically inclined, you may find it easiest to compile the project yourself to get it running at this current point in time.
Installation instructions for some ports can be found in our Wiki.
Library substitutions
To achieve our goal of platform independence, we need to replace any Windows-only libraries with platform-independent alternatives. This ensures that our codebase remains versatile and compatible across various systems. The following table serves as an overview of major libraries / subsystems and their chosen replacements. For any significant changes or additions, it's recommended to discuss them with the team on the Matrix chat first to ensure consistency and alignment with our project's objectives.
