subj.

HI, Gio and all.

as a matter of fact, the title says it all. I do the editor of block diagrams.

And already completed it, except that I don't like the way connecting my blocks.

I've tried several libraries. but the desired result is not obtained (it should be noted that I didn't even do A-* mechanism of the library, Wade).

Step by step what I do - split the screen into cells, translate the coordinates of objects in the grid coordinates, then build an array and look for the path in it, then draw lines and points. I do not like the results - either the steps or the algorithm chooses the path - down-right, although visually it would be more correct - right-down. Ie, to me it is necessary that the devices were connected as fewer kinks and lines and it does not give complications in distances between the blocks.

Something similar you have in the flow-chart editor, but I have a completely different specificity of blocks - the number of inputs is limited, each has its own property, and I do not implement through ctx primitives, but through sprites,

 I would love to make a strict rule for a connecting object-1 point and two lines, but alas, the user wants to move the blocks and the block with the line should not intersect.

as a connector between the blocks I use

let joint = {
lines:[],//array of sceneobjects
dots:[],//array of sceneobjects
begin:{},//grid coordinates of begin
begin_sprite:{],//link to sprite of begin 
end:{},//grid coordinates of end
end_sprite:{}//link to sprite of end
}

I duplicate the coordinates because when a line is drawn it has no reference to another block so the connector can be bound either just to a point or to a specific sprite.

in General, Gio (or someone else) do you know a algorithm that would be good to connect blocks at any distance with the least number of angles and the least expensive pathfinding algorithm?
