I'm sorry to hear the sk module is going away. I've been having fun with it. Hope it's only temporary.

I do this by supplying a custom action for the ui element which overloads call(self, bnt): self.action(btn) to perform the action. Then I simply add whatever I need to this object and access it with the ui.action member.

I often use the copy module.
import copy

newobj = copy.copy(oldobj)

Misha, try setting new.alpha = 1

misha,
regarding your issue.
new = particle_tpl.copy() #does not correctly copy the physics body.
new.physics_body = particle_tpl.physics_body.copy() #should fix your problem.

node.copy() does not copy the physics body correctly. The node copy points to a physics body but I think it's the same as the original. I have to manually make a copy.

I really think sk.Scene.update() should take a delta time parameter instead of assuming 16ms.

Still a bug: In one of my editor scripts I still get a row_height of -1 from a TableView. Now it actually seems to never be set. I'm manually setting it during init at the moment. I checked the value in did_load() and layout(). Btw my editor script presents a view. I get a -1 if run directly as well. I have reported this in previous versions of 1.6. The height worked in 1.5 but other issues prevented this script from working before.

Bug: I was adjusting the order of editor actions, moving the default ones to the bottom of the list. Suddenly only the last script in my list was available . I removed and readded mine (about 6) but still only the last one is available for selection. They still show up in the editor action list in settings though.

ui.TableView.row_height is still always -1.
