Isometric Perspective

This module changes the map, tiles and token artwork/sprite for use with maps and tokens drawn using an isometric perspective.

Features

Here are some of the features the module offers.

• Dual Canvas Perspectives: You can use top-down isometric or native isometric maps. In native isometric mode, you can adjust the scale of the map.
• Token Sprite Adjustments: You can fine-tune the position of the token sprite, as well as its scale. Increasing the size of the token automatically increases the size of the sprite.
• Tile Sprite Adjustments: You can also fine-tune the sprite position and scale, making easy to copy and paste multiple tiles. There's also a easy Flip Tile option.
• Token Height Visual Cues: If a token has any elevation, its sprite adjusts to reflect the height, with a round shadow and line sprites being created for clarity.

Compatibility

The basic functionality of this module is just apply a transformation on the canvas (rotate and skew) achieving an isometric perspective while undoing that transformation on the background, tokens, and tiles. This approach ensures compatibility with most Foundry core features and modules that don’t directly interact with these systems. Native functions like templates, drawing, and lighting should work as intended.

These are the modules I've tested and their status:

• Working
  Drag Upload
  Elevation Ruler
  FXMaster
  Levels
  Sequencer
  Tactical Grid
  Tile Sort
  Token Ease
  Token Movement 8bit Style
  Wall Height

• Partially Working
  DFred Droppables (tokens are dropped far from the point where the mouse is pointing. Just zoom out to find where they are)
  Drag Ruler (sometimes the values ​​do not appear, but this is a problem with the drag ruler and not this module)
  Token Magic FX (some area effects, like sphere effects, are deformed)
  Rideable (if both mount and rider tokens have the same size, isn't possible to select the mount token)

• Not working
  Image Hover (render the art, but it moves with the pan of the canvas. You can only see it if you use hotkeys, and will not show the entire art)

Known Bugs

• Scene Grid Configuration: The canvas background configuration in Scene Settings > Grid > Ruler Tool ( ) does not work.

  • Workaround: The art scale function has been recreated in the Isometric tab, and you can set the offset in the Grid tab. For align the grid, you really should use the module Grid Scaler for that.

• TokenHud and TileHud Position: The position of the TileHud (menu on right-clicking a tile) is aligned with the left vertex, but sometimes will be far away from the token/tile.

  • Workaround: In most cases, running the macro canvas.draw() is enough to fix.

To-Do List

• [ ] Add new perspectives.
• [ ] Code to handle tiles and walls.
• [ ] Code to handle occlusion of tiles and tokens.
• [ ] Different art for isometric and top-down views.
• [-] Check compatibility with other modules.
• [x] Bugfix: Change tokens properties (vision) change token position.
• [x] Using core foundry controls for token scale and anchor. (Added in the code as an alternative, need to see yet if is worth it using).
