* Add multiplayer extension * Fix animation system to work when host is outside ISLE world - Move TickHostSessions outside m_inIsleWorld gate so the host can coordinate animations from any world - Load animation catalog early in HandleCreate so the host can coordinate before entering the ISLE world - Use network-reported positions for remote player location detection instead of requiring spawned ROIs - Always erase sessions at launch — the host's job ends when the animation starts; clients play and complete independently - Replace BroadcastAnimComplete with locally-driven completion callbacks: host generates eventId at launch, clients cache completion JSON at start time, fire it when ScenePlayer finishes - Make StopAnimation only do local cleanup (stop playback, cancel own interest, reset coordinator) without destroying the session host, so other players' sessions survive world transitions - Broadcast state=0 in ResetAnimationState for full teardown paths (shutdown, reconnect, host migration) so clients aren't left with stale session state * Fix use-after-free crash in ScenePlayer when remote player disconnects mid-animation When a remote player's ROI is destroyed (disconnect, timeout, or respawn), notify all active ScenePlayer instances to null out dangling references before the ROI is freed. The animation engine already handles null ROI map entries gracefully, so playback continues for remaining participants. * Fix crash when performer's child ROIs are left dangling in ScenePlayer NotifyROIDestroyed now walks the parent chain to also invalidate child ROIs of the destroyed performer (head, limbs, etc.) that were placed into the roiMap by BuildROIMap. The ancestor walk happens once; all other fields are cleaned with simple pointer equality. * Allow spectator to play click animation during scene playback * Make PTATCAM track spectator ROI instead of camera in ScenePlayer * Only regenerate emscripten version files when git state changes Replace add_custom_target(ALL) with add_custom_command(OUTPUT) so the version script only runs when .git/HEAD or the current branch ref file changes, instead of on every build. * Fix ROI name collision causing dangling pointers in NPC locomotion roiMaps When ScenePlayer created cloned NPC ROIs for cooperative animations, it renamed them to match the original character name and added them to the ViewManager. This created a name collision: two ROIs with the same name. The original game's AppendROIToScene searches by name and stops at the first match, so if a locomotion BuildROIMap ran while the clone existed, it could capture pointers to the clone's child ROIs. When the clone was later destroyed (CleanupProps), those roiMap entries became dangling pointers, crashing in AnimateWithTransform at roi.h:151 (SetVisibility). Fix: use the alias mechanism (already supported by AnimUtils::BuildROIMap) instead of renaming clones. Also unify all ROI name generation behind a shared counter to prevent character manager key collisions. |

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.

Building
This project uses the CMake build system, which allows for a high degree of versatility regarding compilers and development environments. Please refer to the GitHub action for guidance.
