Can't get vs.TrueTypeToPoly(text) to work

[Nomi]

Hi all,

 

Coding question for those who write their own nodes. Every time I try to run a node with the (a,b) = vs.TrueTypeToPoly(text) the program crashes - has anyone run into this/has any suggestions? I've attached a simple sample node that creates text and then uses the above command to turn it into poly lines. It doesn't crash if I don't try to assign the output to the tuple (a,b), but also doesn't convert the text.

 

Thanks,

 

Naomi

TrueTypeToPoly take a handle pointing to the text name a block of text as a parameter.

 

This seems to run:

 

(a,b) = vs.TrueTypeToPoly(vs.FSActLayer())

 

This creates a group containing the polygonized text. You probably need a vs.Redraw or RedrawAll to get the display right.

 

Be careful about passing a nil handle. When I did it crashed VW to the finder.

Aha, didn't know there were different ways to grab the handle for the created text. The node would run once but crash on the second time for some reason with

(a,b) = vs.TrueTypeToPoly(vs.FSActLayer()). Did some playing, this combination seems to be the winner:

 

text = vs.CreateText('hello')   

(a,b) = vs.TrueTypeToPoly(vs.LNewObj() )

self.Params.out.value = b

 

Thanks!

Great!

 

There are lots of different ways to get handles to objects and if you are going to do much scripting, handles are one of the most important aspects of PythonScript (VectorScript) to wrap your head around.

 

Ask again if you need more help.
