Hey there,
i’m doing a qix game.
The moment i set the marching squares at 1x1 px i got an error message.
I need 1x1 px cause i want the rectangle to be perfectly drawn.
I wonder if it’s a bug or not.
here ss.
I tried the marching square qix example project with the online version without making any changes. It worked for a little while then I got this error.
what i’m trying to do is increase precision to 1 px to get precise geometries…since it is a qix game. I guess that is the problem…but i could be wrong
I didn’t make any changes to the example. It still crashes. This is the full error that I get.

well…it looks like it’s gonna need a fix
The example uses MarchingSquare 0.5.0 when the lastest version is 0.5.7. I’ll update the example.
I wouldn’t recommend a cell size of 1x1 as it would completely defeat the purpose of the marching square algorithm. Indeed, tiles of 1 pixel make no sense.

I opened the example and updated the marching square extension and played it for awhile without any crashes. It seems good.
Ok, mind a question…
is It possible to draw a precise rectangle (sry, i dont mean tò draw rectangle, i mean to get a precise rectangle contour of field by additive formula) with marchin squares?
Cos everytime the rectangle get rounded on corners cos i guess it is how marching squares works.
But still i wonder if it is possible
Bump.
It was my 0.50 ver of marching squares acting strangely.
With 0.57 it’s working fine (not perfectly).
Thx Davy
