* Fix split-screen join failing when connecting to a remote host via UI
When a non-host client connected to a remote server through the in-game
UI (as opposed to the -ip/-port command line flags), the global variables
g_Win64MultiplayerIP and g_Win64MultiplayerPort were never updated from
their defaults ("127.0.0.1" and the default port). JoinSplitScreen()
relies on these globals to open a second TCP connection for the local
split-screen pad, so it would always attempt to connect to localhost,
failing immediately on any remote session.
Fix: update g_Win64MultiplayerIP and g_Win64MultiplayerPort inside
JoinGame() once the primary connection is established. This ensures
subsequent JoinSplitScreen() calls always reach the correct host
regardless of how the session was joined.
Additionally, guard PushFreeSmallId() against recycling smallIds in the
range [0, XUSER_MAX_COUNT), which are permanently reserved for the
host's local controller slots. Previously, if a host-side local pad
disconnected its smallId could re-enter the free pool and be handed
to an incoming remote client, causing that client's IQNetPlayer slot
to collide with a local pad slot on the non-host machine.
* Fix tutorial popup positioning in split-screen viewports
Replace the manual switch-case that computed viewport origin with the shared GetViewportRect/Fit16x9 helpers (from UISplitScreenHelpers.h). This ensures the tutorial popup is positioned and scaled consistently with the rest of the split-screen UI, fitting a 16:9 box inside each viewport and applying safezone offsets correctly.
Also adds missing default:break to safezone switch statements to silence compiler warnings.
Made-with: Cursor
* Prevent split-screen join when game window is not focused
Add g_KBMInput.IsWindowFocused() guard to the tryJoin condition so that gamepad input from background windows does not accidentally trigger a split-screen player join. This avoids phantom joins when the user is interacting with another application.
* Open debug overlay in fullscreen UI group during split-screen
Pass eUIGroup_Fullscreen to NavigateToScene when opening the debug overlay, so it spans the entire window instead of being confined to a single split-screen viewport. This makes the debug info readable regardless of the current split-screen layout.
* Fix non-host split-screen connections missing world updates
Previously, secondary (non-host) split-screen connections used isPrimaryConnection()
to gate nearly all world update packets, meaning the second local player would never
receive tile updates, entity movement, sounds, particles, explosions, etc.
The fix introduces per-connection tracking of which entities and chunks each
ClientConnection has loaded, and uses that information to decide whether a secondary
connection needs to process a given packet or if the primary connection already
handled it.
New members in ClientConnection:
- m_trackedEntityIds: set of entity IDs this connection has received AddEntity/AddMob/AddPlayer etc. for
- m_visibleChunks: set of chunk coordinates (packed into int64) this connection has marked visible
- Both sets are cleared on close(), respawn (dimension change), and destructor
New helpers:
- findPrimaryConnection(): walks the MultiPlayerLevel connection list to find the connection on the primary pad
- shouldProcessForEntity(id): secondary connection skips the packet only if the primary is already tracking that entity
- shouldProcessForPosition(x, z): secondary connection skips the packet only if the primary already has that chunk visible
- anyOtherConnectionHasChunk(x, z): used when a chunk becomes invisible to avoid hiding it from the level if another connection still needs it
- isTrackingEntity(id): public accessor used by shouldProcessForEntity on the primary connection
Packet handler changes:
- handleMoveEntity, handleMoveEntitySmall, handleSetEntityMotion, handleTakeItemEntity:
replaced isPrimaryConnection() with shouldProcessForEntity() so secondary
connections still process movement for entities they know about
- handleExplosion, handleLevelEvent:
replaced isPrimaryConnection() with shouldProcessForPosition() so block
destruction and level events fire for the correct connection based on chunks
- handleChunkTilesUpdate, handleBlockRegionUpdate, handleTileUpdate, handleSignUpdate,
handleTileEntityData, handleTileEvent, handleTileDestruction, handleComplexItemData,
handleSoundEvent, handleParticleEvent:
removed the isPrimaryConnection() guard entirely -- these are world-state updates
that all connections must process regardless of which pad is primary
- handleChunkVisibilityArea / handleChunkVisibility:
now populate m_visibleChunks; on visibility=false, setChunkVisible(false) is
only called on the level if no other connection still has that chunk loaded
- handleAddEntity, handleAddExperienceOrb, handleAddPainting, handleAddPlayer,
handleAddMob: now insert into m_trackedEntityIds on arrival
- handleRemoveEntity: now erases from m_trackedEntityIds on removal
- handleLevelEvent: removed a duplicate levelEvent() call that was always firing
regardless of the isPrimaryConnection() check above it (latent bug)
MultiPlayerLevel: added friend class ClientConnection to allow access to the
connections list without exposing it publicly.
* Fix fullscreen progress screen swallowing input before load completes
Two issues in UIScene_FullscreenProgress::handleInput:
1. The touchpad/button press that triggers movie skip or input forwarding
had no guard on m_threadCompleted, so pressing a button during the loading
phase would fire the skip/send logic before the background thread finished.
Added the m_threadCompleted check so that path is only reachable once
the load is actually done.
2. The `handled = true` assignment was missing from that branch, so input
events were not being consumed and could fall through to other handlers.
Added it unconditionally at the end of the block.
* Update player count decrement logic in PlatformNetworkManagerStub
Refactor the condition for decrementing the player count in CPlatformNetworkManagerStub::DoWork. The previous check was replaced with a while loop to ensure that the player count is only decremented when there are more than one player and the last player's custom data value is zero. This change improves the handling of player connections in the network manager.
* Refactor safe zone calculations in UI components for consistency
Updated the safe zone calculations across multiple UI components to ensure symmetry in split viewports. Removed unnecessary assignments and added comments for clarity. Modified the repositionHud function to include an additional parameter for better handling of HUD positioning in split-screen scenarios.
* Gui.cpp: fix F3 debug overlay in splitscreen + minor perf cleanup
The F3 debug screen was badly broken in splitscreen: it used the GUI
coordinate space which gets distorted by the splitscreen scaling, so
text appeared stretched, misaligned or completely off-screen depending
on the viewport layout.
Fixed by setting up a dedicated projection matrix using physical pixel
coordinates (g_rScreenWidth / g_rScreenHeight) each time the overlay is
drawn, completely decoupled from whatever transform the HUD is using.
The viewport dimensions are now computed per screen section so the ortho
projection matches the actual pixel area of each player's quadrant.
Version and branch strings are only shown for player 0 (iPad == 0) to
avoid repeating them across every splitscreen pane.
Also removed a few redundant calculations that were being done twice in
the same frame (atan for xRot, health halves, air supply scaled value).
These are minor and have negligible real-world impact; more substantial
per-frame caching work (safe zone calculations etc.) will follow in a
separate commit.
Added Brown Rabbit model and a basic ai system.
added toast variant, others have to be implemented.
TODO:
add other variants, add their spawn in the biomes, add IDS_RABBIT And change sounds.
ADD color to the spwanegg.
Acacia and Dark Oak Logs, Planks and Stairs.
Fences, Fence Gates and Doors for Spruce/Birch/Jungle/Acacia/Dark Oak.
Iron Trapdoors and Inverted Daylight Sensor.
writeRuleFile() was missing the schematic file count integer before the schematic entries. The reader in readRuleFile() expected this count, causing a stream misalignment that led to an assertion failure (Unrecognised schematic version) when reloading a saved tutorial world.
The fix writes the count on save and adds backward-compatible reading that detects old saves (without count) via a peek heuristic and falls back to count-less parsing.

* LCEMP RCE Fixes WIP
Based on d017bfc30a
* Update to LCEMP's ByteArrayIO version
Fixes compilation since ours was missing some revisions from LCEMP
* Add additional safety checks missed in first pass
* Remove duplicate recipe count check
Players joining a server with a UID already in use are now disconnected
instead of the existing player being force-kicked. The previous behaviour
introduced in #767 allowed two clients with the same UID to coexist,
causing invisible players and undefined behaviour.
Also removes a per-frame debug printf in gdraw_SetViewSizeAndWorldScale
that was left in from earlier resolution-fix work.
* Fix split-screen UI wrong positioning on window resize
In vertical split at window heights below 1080, ComputeTileScale's min-scale clamp (>= 1.0) prevented the SWF from scaling down to fit, cropping the bottom and causing repositionHud to shift HUD elements downward. Chat and Tooltips additionally applied an offset from ComputeSplitContentOffset that only produced correct values at the 1920x1080 design resolution.
Override the scale for vertical split so the SWF fits the full window height when it is shorter than the movie. Remove the broken content offset from Chat and Tooltips -- the tile crop already positions the content correctly.
* Fix gamma post-process in split-screen
The gamma shader sampled the full backbuffer texture (UV 0..1) into each player's viewport, stretching the entire screen into every split region. Extended the shader constant buffer with per-viewport UV offset and scale so each pass samples only its own portion of the backbuffer.
ComputeViewportForPlayer was hardcoded to top/bottom for 2 players, ignoring the vertical split setting. Rewrote it to read each player's m_iScreenSection directly, which already accounts for the split orientation preference.
Secondary players have no Graphics menu and cannot change gamma. CachePlayerGammas now reads the primary player's setting and applies it uniformly to all viewports.
