TextPlus: How to label an Object using its Object name

Anonymous — Thu, 13 Apr 2017 05:39:20 GMT

Is it possible to label an Object with its Object Name using TextPlus?

I have watched the TextPlus Set Value as Text tutorial but this only enables values from a reference Object, not its Name

I have ~200 objects to label in my scene, it would be much quicker if there is a method to support this, rather than having to type out the individual object names 200 times

thanks

Hello @Anonymous and welcome to the community,

Since this thread didn't get a reply and I'm not really great at scripting I am going to move this thread to the programming forum in the hopes that you get a reply there. Thank you.

Best Regards,

Hi, here's a short script that applies a textplus label to every non-textplus object in a scene. You can use it as a starting point for what you're trying to do.

-- label everything in the scene w/ a textplus

fn label_it obj = (

	str = obj.name

	t = TextPlus size:10
	t.SetFont "Arial" 0
	t.ResetStyle()
	t.ResetString()
	t.AppendString str
	t.pos = obj.pos
	bb = nodeLocalBoundingBox obj
	t.pos.z = bb[2].z
)

allObjects = $*
for obj in allObjects do (
	
	print obj.name
	-- don't label textplus objects, that would be silly
	if (classOf obj != TextPlus) do (
		label_it obj
	)
)

Nice one Drew, I tested it and it's great! Does that help @Anonymous?

If you feel that this solves the issue for you @Anonymous, please mark Drew's post as the solution. Thanks!

nice @drew_avis, if you don't mind, I think this is useful (just 1 bold line added)

-- label everything in the scene w/ a textplus

fn label_it obj = (

	str = obj.name

	t = TextPlus size:10
	t.SetFont "Arial" 0
	t.ResetStyle()
	t.ResetString()
	t.AppendString str
	t.pos = obj.pos
	bb = nodeLocalBoundingBox obj
	t.pos.z = bb[2].z
	t.parent = obj   -- link label to object
)

allObjects = $*
for obj in allObjects do (
	
	print obj.name
	-- don't label textplus objects, that would be silly
	if (classOf obj != TextPlus) do (
		label_it obj
	)
)

just so if you move the objects around, the labels go with them...

@Anonymous, good addition - you could also put the labels on their own layer to easily show/hide. Lots of potential for fun with this one.

Happy to do whatever I can @Anonymous. Thanks for the kind words. Good idea here @Anonymous and thank you very much @drew_avis for your awesome code.

I made a small addition as well, adding a tiny bit of extrude to the lettering so when zoomed out the faces don't overlap. (Default setting of textplus.)

-- label everything in the scene w/ a textplus

fn label_it obj = (

	str = obj.name

	t = TextPlus size:10
	t.SetFont "Arial" 0
	t.ResetStyle()
	t.ResetString()
	t.AppendString str
	t.pos = obj.pos
	bb = nodeLocalBoundingBox obj
	t.pos.z = bb[2].z
	t.parent = obj   -- link label to object
        t.extrudeamount = 0.025
)

allObjects = $*
for obj in allObjects do (
	
	print obj.name
	-- don't label textplus objects, that would be silly
	if (classOf obj != TextPlus) do (
		label_it obj
	)
)

Best Regards,
