Map editor help
Choose a layer and tile, then paint. Fill replaces connected matching tiles; Pick copies a tile and returns to Brush. Erase sets only the chosen layer to zero. Tile IDs and middle-word bits are preserved.
Use Pan or hold Space to move the view. Phones start in Pan; the tiles button opens the shared tile and layer sheet. Pinch zoom, fit and native-size zoom work like the Dark Ages editor. Grid, Objects and Preview affect only the view. Undo and redo apply to strokes and fills.
Import a local MAP4 file or NexusTK JSON map; drag and drop also works. Files stay in your browser. MAP4 import/export supports the verified 17 × 15 client background format. Other sizes, up to 256 × 256, use NexusTK JSON. JSON also retains existing map metadata. Export offers a map file or a PNG of the current view.
The library includes historical community-preserved maps and three NexusTK 7.52 client backgrounds. Historical maps are not verified as current official world maps. Pristine maps use a reduced overview when fitted; editing or zooming in uses the tile artwork. Static ground and scenery retain native pixels and placement; lighting, palette cycling and native occlusion are not simulated.
Keyboard: B brush, E pick, F fill, X erase, H pan, G grid, O objects, P preview, Ctrl/Cmd Z undo, Ctrl/Cmd Y redo, Ctrl/Cmd S export. On the focused canvas use arrow keys to choose a cell and Enter to apply the selected tool. Right-click or Alt-click picks a tile.
Selections & clipboard
Choose Select (M) and drag across tiles to mark a rectangle. Brush, Fill and Erase stay inside the selection. Open Selection options (…) to choose the active layer or all layers, or select the whole map.
Copy keeps tile values in this editor tab. Cut copies and clears them; Clear removes them. Paste shows a blue placement outline; click to place its top-left corner. Tiles outside the map are clipped. A single-layer copy pastes into the active layer; an all-layer copy restores every layer, including zeros. Each cut, clear or paste is one undoable action.
Ctrl/Cmd A selects all; C copies; X cuts; V pastes. Delete or Backspace clears the selection. Escape cancels paste or clears the selection. Use arrows and Enter on the canvas for keyboard placement. The clipboard lasts until this tab is closed or reloaded.
