Functions

get2dCoordsFromIso

  • get2dCoordsFromIso(x: number, y: number, z: number): [number, number]

  • Converts a 3D grid location to a 2D isometric screen projection.

    Parameters

    • x: number

      The X grid coordinate in 3D space.

    • y: number

      The Y grid coordinate in 3D space.

    • z: number

      The Z grid coordinate in 3D space.

    Returns [number, number]

    • An [X, Y] array of the 2D screen coordinates.

getZIndex

  • getZIndex(x: number, y: number, z: number): number

  • Gets the Z-index of a grid location.

    Note: This is used to draw sprites and graphics to the screen in the correct order (back to front, bottom to top).

    Parameters

    • x: number

      The X grid coordinate in 3D space.

    • y: number

      The Y grid coordinate in 3D space.

    • z: number
