Lining up isometric 2d grid with tile map

[Snedden27]

Hello , please excuse me if this is too elementary but been stuck on this for while.

This is similar to this question here:

Help Matching the Hexagon Grid Graph to the 2018.2 2D Hexagon Grid

I’m not a math person so for others who stumble on this, I’ll explain how I reached the conclusion for the values The default unity grid is 1:1 ratio hexagons. [image] To fix this I need to either scale up the vertical axis, or scale down the horizontal. I followed This site for the ratio which has the ratio listed as sqrt(3):2 so I got a unity grid size of (sqrt(3), 2, 1) or (1.732051, 2, 1) which I then reduced to (sqrt(3)/2, 1, 1) or (0.8660254, 1, 1) Which makes them regular.

For me I am trying to make top down isometric game and the grid shape is rectangle .

I am having a hard time mapping the time map to A star grid,

This are my settings for the tile renderer and what it looks like:

This are my settings for AStar grid:

I tried to rotate and play around with the values of node side,depth, rotation, IsoAngle etc to get the Astar grid close to possible to tile renderer grid, but its not exact as you see here:

Maybe there is some math here I need to do, or something more fundamental I am missing , please help, thanks

it was on these theme Unity 2108.3 Isometric Tilemaps (SOLVED)

but i think this issue on tilemap side/ if you do trick - null scale 0.57 and grid rotate under it to 45 it will be perfect lines over astar grid(but iso sprites will look wrong and trick not useful)

so its smth strange in tilemap isometric mode calculations

i need this too/ so i did some experiments/ for me works this setup tilemap anchor point to 1 1

and grid scale 1.4+

no mathematiks just putting numbers and watching how it looks in editor/ you can change them

and sorting for tiles so they dont overlap/ maybe chunk mode instead of individual will be good too

upd. i understood 0.707 node scale as in that topic Unity 2108.3 Isometric Tilemaps (SOLVED) 0.707* 2 =1.414 tile scale as here. so you choose yourself what to scale

thanks for your response. but seem like I dind’ t have to scale the grid to 1.4142, just making the setting of the A8 grid grap to these , worked for me,

Shape: Isometric
Node size: 0.707
Isometric angle: Dimetric(60)
Rotation: 225

although I don’t think we should have to this trial and error thing.

do what you want man/ it was just thoughts out loud mostly for myself

Hi

This is a very good point. I have implemented an alignment function now, and it will be available in the next beta version.
