The 1.1.10 update brings in a new function, ScaleVector3(Vector scl) : Vector3 which takes in a vector and then scales it so it fits inside the grid. This is similar to AlignVector3, which was introduced in the last update, to allow performing the aligning and scaling without having to provide an actual Transform.
Another progress update: WorldToGrid and GridToWorld are now implemented.
For those who don't know, those two functions convert a point's coordinates
from world space to grid space, the coordinate system used to locate points
relative to the grid's properties, and back. For rectangular grids it's a
fairly simple idea, the grid can be represented as a standard Cartesian
coordinate system. With hex grids that won't do it, you simply cannot force a
hex grid into a Cartesian coordinate system, you need to find something else.
Fortunately there are several topologically identical possibilities with
easier, more intuitive coordinate systems. For the first release I have decided
to use the herringbone pattern:
The align feature has been giving me quite some headache lately. For small objects it's easy, just fit them inside the nearest hex. It gets more interesting once your object spans over more than one hex. Here is a screenshot from the game "Age of Wonders" for PC (I upscaled the image manually, AoW has a very low resolution)
Surprise update! Version 1.1.9 just got approved and it contains quite a few changes:
The other day I had the following problem: I had a list of Transfoms and I
wanted to remove the entries that met a certain condition. This is what I had
written:
Good news at last, I just finished the finding functions for vertices, both in grid space and in world space. Here is a screenshot where the yellow gizmo indicates the vertex closest to the grey sphere.
