Draw texture on Lines2D

[Knight]

I want the player to draw a free-form line on the screen. I've managed it by using Lines2D. Now I want to put some textures on the line. How should I do that?

Hi and welcome to the forum and apologies that it has taken so long to get a reply, and one that will not be all that helpful sorry to say. Lines2D is part of Canvas2D which I not very familiar with however the documentation states that Lines2D inherits from Shape2D which uses a Brush for its fill and only uses a solid color or a gradient color, so unless a Canvas2D expert says otherwise I would say no textures.

There is an alternative, using a tube to draw the line

Check the PG that goes with the above post.

Hi guys.

I was thinking of one other way. Use a standard BJS plane (.isPickable = false), parented to camera (in a way where plane area == renderCanvas area)... then apply empty BJS dynamicTexture onto plane.  (Like a piece of clear glass... placed precisely atop the renderCanvas. Similar to a ScreenSpaceCanvas2D, but not one.) 

Then use .getContext() to get the context2d of that dynamicTexture, and start making "strokes" on it.    Remember to update your dynamicTexture after each change.

"Pattern" is a type of fill, there.

pattern = context.createPattern(image, repetition)

"image".  Yay!  Could be possible.  Wear your hard hat... things might blow up.    (probably won't)

Some crazy playground-maker was doing something weird... here.  Looks pretty fancy.  I found that PG ... while I was searching-for a simple playground that showed .update()... like this playground... line 32.  Party on, guys.
