IsometricMap

The IsometricMap is a special tile map that provides isometric rendering support to Excalibur

The tileWidth and tileHeight should be the height and width in pixels of the parallelogram of the base of the tile art asset. The tileWidth and tileHeight is not necessarily the same as your graphic pixel width and height.

Please refer to the docs https://excaliburjs.com for more details calculating what your tile width and height should be given your art assets.
