Map editor help
Choose a layer and tile, then paint on the map. Fill replaces connected matching tiles on that layer. Pick copies a tile and returns to Brush; Erase sets it to zero. Use Pan or hold Space over the canvas to move the view. Phones start in Pan mode; use the stacked tiles button beside the hand to choose tiles and layers. Choosing a palette tile closes the sheet and returns to painting. Touch screens support pinch zoom; tap the zoom percentage to return to native size.
Grid, Objects and Preview sit at the top of the map. On phones their icons are a grid, stacked tiles and an eye; highlighted controls are on. Tile information is available with the layer controls and shows coordinates and tile values. These display choices are remembered in this browser. Preview hides the tools and grid so you can pan without painting; press Preview again or Escape to resume editing.
Map files contain no dimensions. Enter the original width and height when importing; the file size must match exactly. Estimated library dimensions are marked. Dimensions can rearrange the existing cells into rows without changing their bytes. Undo and redo also restore dimension changes.
Tile previews show the first animation frame; the editor does not infer collision. Files stay on your device. Export regularly to keep a copy.
Keyboard: B brush, E pick, F fill, X erase, H pan, G grid, O objects, P preview, Ctrl/Cmd Z undo, Ctrl/Cmd Shift Z or Y redo and Ctrl/Cmd S export. On the focused canvas, arrows choose a cell and Enter applies the tool. Right-click or Alt-click also 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.
