Center pointy_rectangle to the window and field_of_movement input

[Godnoken]

Hi,

I have two issues;

The first one is that I am struggling to center a 15 by 11 sized pointy_rectangle.

The only way I manage to do so at the moment is by doing something like shapes::pointy_rectangle([-7, 7, -5, 5]).
It does center it, however, the x, y coordinates I receive are not desirable in that solution. I don't want any negative x, y, but 0-14 and 0-10 instead.

Is there an easy way to solve this? I assume it would involve not using hex_to_world_pos.

Edit;

I 'solved' the first problem by continuing to use [-7, 7, -5, 5]

with

hex.x = (hex.x - 7).abs();
hex.y = (hex.y - 5).abs();

and inverting x, y on the layout so I can present 0,0 in the top left corner of the rectangle and 14, 10 in the bottom right.

Of course, this is purely to visualize the tile's x, y with text, and I continue to use the [-7, 7, -5, 5] coordinates for the position.

Not ideal but it works for my purposes.

The other issue is that the visual placement is for some reason not the same as the coords that handle_input picks up (taken from "field_of_movement" example). It's off by 1 tile, as if there's another outer layer of hexagons. Maybe that's by design from the example and I just don't see where?

Thank you so much for this amazing crate! Let me know if I need to clarify anything.

You could change the world origin in the HexLayout to offset everything, but if you are using the shapes module you might need to rewrite the rectangle function to do what you intend and offset all hexagons to avoid negative values, this combined with the origin change would make a centered rectangle

[Godnoken]

Yup. Try the example given in field_of_movement and change the origin and you'll get this result.

I think know what the problem is, the PlaneMeshBuilder that creates the hex mesh takes in account the layout origin, and shifts everything

[ManevilleF]

Fixes it, I gotta rethink that API, because it makes sens to take in accout the origin when generating meshes, unless, like for bevy we want the mesh vertices to be centered around 0, 0

[Godnoken]

Brilliant, thank you very much! :)

[ManevilleF]

Could you check #139 @Godnoken ? The new center_aligned method should fix that problem

[Godnoken]

Thank you! I will look into it.
