[Geomerative library] Parkinson text editor

in Contributed Library Questions • 5 months ago

Hello there,

I'm trying to make a simplified "parkinson" text editor. I used two snippets to build it but I have two main issues :

- the return button doesn't work, only makes a space

- there are lines between letters that I'd like to remove, but I can't figure this out.

I use geomerative library. Could you please help me ? Here's my code :

More motion but this time with a random movement
to make the text wiggle. Again key'A' to freeze.

I never used the Geomerative library (despite its interest) and it appears not many people know it. Or perhaps edit your subject to include its name, perhaps it will attract knowledgeable people (perhaps even the author of the library!).

Hi there,

The handling of the "return" is not handled by geomerative, you will have to handle it yourself, by starting a new shape and drawing it a few pixels lower. Text layouting is quite a complex topic and it is a bit out of the main focus of the lib.

To avoid the lines between letters you simply should use the getPointsInPaths() method instead of the simple getPoints(). See the code below:
