# Isometric Tiles — the diamond map view
|
|
|
|
Isometric Tiles draws tile maps at an angle, as a grid of 2:1 diamonds, so buildings and trees stand up out of the ground. It is one of two map views for the shared Tile Rendering engine; the other is Top-down Tiles. The same maps, events and saves work in both.
|
|
|
|
|
|
|
|
## What is different from the top-down view
|
|
|
|
- **Diamond cells.** Each map cell is drawn as a diamond twice as wide as it is tall. The logical grid is still square: a cell has the same four neighbours as before.
|
|
- **Standing objects.** Buildings and other multi-cell objects that a tileset marks for it are drawn as upright pictures or as several flat faces, instead of flat tiles.
|
|
- **Characters** pick the sprite row that matches their direction on the diamond grid.
|
|
- **Clicking** on the map selects the diamond under the pointer; the RPG map editor uses the same rule.
|
|
|
|
|
|
|
|
What does not change: walking rules, collisions, events, battles, saves, lighting and time of day are owned by the RPG mod and Tile Rendering and behave the same in both views.
|
|
|
|
## Limitations
|
|
|
|
- **Keys follow the grid, not the screen.** Up and down (W/S, arrows) move along one diagonal of the screen, left and right along the other, because they move the hero one cell on the square grid.
|
|
- **The edges of a map show.** Near a corner of the map you see the empty background beyond the diamond's edge, as in the picture above.
|
|
- **Tilesets must be prepared.** Objects look upright only when the tileset describes them as groups; ordinary tiles are laid flat on the diamonds.
|
|
|
|
## Turn it on
|
|
|
|
In the game's scheme (**Mods & Collections → Collections → the game → Edit scheme**), include this mod and set **Map projection** to **Isometric**. The value of the `tile.renderer` setting is `isometric`:
|
|
|
|
```json
|
|
"settings": { "tile.renderer": "isometric" }
|
|
```
|
|
|
|
To try it once without changing the game, start it with `--tile-renderer=isometric` on the command line. RPG Plus already includes both renderers, so only the setting needs to change.
|
|
|
|
## If something goes wrong
|
|
|
|
1. **The map is empty.** The game's **Map projection** asks for a renderer that is not included; include this mod or choose another projection.
|
|
2. **The hero walks diagonally.** That is how the keys work in this view (see Limitations).
