How to change "linkdistance" while force directed layout is running?

[cenk]

Is there a way to lengthen / shorten edges while the layout is
running?

I tried stopping, updating linkdistance and resuming, no hope...

Thanks.

The link distances and strengths are cached on the link objects, so
you need to call start() when these parameters change rather than
resume().

Trying this but can't seem to get it working:

force.stop();
force.linkDistance = anotherVal;
force.start();

Thanks :)

That's not how you call a function. Take a look at the documentation:

Thank you, I placed a function inside linkDistance and it works :)

Here's the starters code if anyone will be interested:

var linkDistanceVariable = 50;

force = d3.layout.force()
.linkDistance( function() { return linkDistanceVariable; } )
.size([w, h])
.start();

// Stop the layout

force.stop();

// Set the new linkDistance val

linkDistanceVariable = 150; // new

// Start the layout

force.start();
