MTR Traffic Addon

MTR Traffic Addon - Status Summary What works ========== - The mod is set up as a Fabric 1.20.1 addon for Minecraft Transit Railway. - The local MTR jar is included as a Gradle dependency. - The Traffic Dashboard item opens a client UI with a map view. - Traffic connector entries are listed in the dashboard. - Spawn and despawn connectors show their position, enabled state, active vehicle count, and route status. - Spawn connectors can open the Vehicle Pool screen. - The Vehicle Pool screen can display available MTR vehicles and selected vehicles for a spawn connector. - Connector routes can be refreshed from the dashboard. - Active traffic vehicles can be cleared from the dashboard. - Intersection areas can be created from the dashboard by drawing an area on the map. - Existing intersections are listed and can be selected. - Intersections can be enabled or disabled. - Intersection node auto-detection can be toggled. - Detected intersection nodes are shown on the map. - Node labels are shown on the selected intersection map view, using IN and OUT labels with node numbers. - Signal groups are displayed as clickable rows. - A signal group can be selected directly from the group list. - A signal group can be removed with the small x button next to its row. - IN nodes can be assigned to the selected signal group. - Multiple IN nodes can be assigned to the same signal group, so two lanes in the same direction can go green together. - Selected group nodes are highlighted on the map. - The selected node is highlighted on the map. - Group green duration can be adjusted. - Signal groups can be reordered. - The project builds successfully when Gradle is run with Java 23. What needs improvement or repair ================================ - The default Java environment points to Java 17, but the current Fabric Loom version requires Java 21 or newer. JAVA_HOME should be updated, or Gradle should be configured to use a Java 21+ toolchain. - The dashboard still uses many text buttons. It is clearer than before, but it could benefit from a more compact control layout and stronger visual hierarchy. - The group list currently shows only a limited number of rows. If an intersection has many groups, scrolling or pagination should be added. - The x button deletes a group immediately. A confirmation step or undo would reduce accidental data loss. - Node assignment is functional, but the UI should make it even clearer that only IN nodes can be assigned to signal groups. - OUT nodes are displayed and numbered, but their role could be explained better in the UI. - The map node labels can overlap when nodes are close together. Label placement should be improved to avoid clutter. - The intersection editor still depends on manual clicking and buttons. A drag-and-drop or direct node-to-group interaction would be easier for users. - Group names are generated automatically and cannot be renamed from the dashboard yet. - The dashboard does not currently show a live signal preview of which group is green at the current server tick. - The intersection area drawing workflow works, but it could use clearer visual feedback for the first and second corner. - Vehicle pool management works, but search, filtering, and missing vehicle warnings could be made more user-friendly. - The connector list could use sorting and filtering, especially for worlds with many connectors. - More in-game validation messages are needed when a route is missing, a vehicle pool is empty, or a group has no IN nodes. - README documentation is minimal and should be expanded with setup, usage, screenshots, and troubleshooting. - The mod should be tested in a larger world with many connectors, intersections, and active vehicles. - The mod should be tested in multiplayer to confirm server-client synchronization and permissions. - The saved data format should be reviewed before release to avoid breaking worlds later. - Automated tests are not present. Core traffic routing and signal group logic would benefit from unit tests. - A release build should be checked in a clean Minecraft instance with only Fabric API, MTR, and this addon installed. Build note ========== The project currently builds with: JAVA_HOME=C:\Program Files\Java\jdk-23 The default Java 17 runtime is not sufficient for the configured Fabric Loom version.
