Yeah the real ants is what I was looking for obvs!

Thanks guys :)
I think I just really needed to understand that it’s not
.set_line_dash(sequence [,phase])
but more like:
.set_line_dash([10,15,10,15] ,phase)

Which is what was confusing me..
Duh

Hi
How would I go about making a marching ants/continuously shifting dashed line effect between 2 fixed points using ui.animate anyone?

I’m actually using the reload method and it seems fine - I guess it’s just really inefficient is that what your saying @JonB ?
Thanks for help so far everyone.

Hiya
I’m trying to fill a tableView with rows one after the other with a slight delay between each cell appearing.

This is how I’m trying to do it - but they all still appear in one go:

def tableview_cell_for_row(tableview, section, row):
    cell =ui.TableViewCell("subtitle")
    data = tableview.data_source.items[row]
    cell.bg_color = (0,1,0,0.1)
    cell.text_label.font= ('system',(17*Hmult))
    cell.text_label.text_color = (0,1,0,0.0)
    cell.text_label.text = str(data)
    selected_cell = ui.View()
    selected_cell.bg_color = (0,1,0,0.2)
    selected_cell.text_color = (0,1,0,1.0)
    cell.selected_background_view = selected_cell
    def anim():
        if len(tableview.data_source.items) != row:
            print(row)
            cell.text_label.text_color = (0,1,0,0.5)
            ui.delay(anim,0.2)
    ui.delay(anim,0.2)
    return cell

Thankyou for that got it working at last :). I need to set each cells bg rather than the table - got it.

Hi what is the secret to getting a table view from ui designer to overlay onto a background such that only the text is visible and the cells have no background?
I have tried setting bg_color of data source and/or table view to none but it’s not happening.ie each cell is always white.
I can remove white separator lines using tableView.separator_color=(1,0,0,0).
Why won’t the same work for .bg_color and/or .background_color (and what is the difference between those two anyhow?)
Thanks in advance for any help :)
What am I missing here?

@mikael awesome I will check this out looks like exactly what I’m after thankyou :)

That’s great thanks for explaining !
Im a little confused about a couple of things:

Why do I need to redeclare the bgLines view?

bgv=bgLines(flex='wh')
bgv.alpha=.2
bgv.tint_color='red'
bgv.update_interval=.1

In my case I have made a pyui file that contains the bgLines custom view but pushed to the back.
So is it necessary to subView the buttons/bgLines ? or. Or is there an arrangement of subviews in the UI editor that would get all this working?
I have it working your way but if I am able to reduce any further editing of views etc outside of the UI designer that would be ideal.

If not no probs - just trying to understand the inheritance of the views via the designer.

Ie isn’t the blank canvas of the designer effectively the root ? So if I add a custom view push it to the back and then add a button etc isn’t this the same as :

root.add_subview(bgv)
root.add_subview(topview)

Thanks again for your help!

Ok my original post was a bit of a wacky scene/ui mutation - say I have this code below and want it to play in the bg of a UI that I have constructed using UI designer:

class bgLines(ui.View):
    def __init__(self):
        self.w = ui.get_screen_size()[0]
        self.h = ui.get_screen_size()[1]    
        self.lines=[]
        for v in range(0,random.randint(10,int(self.h/4))):
            self.lines.append(ui.Path.rect
            ((self.w/2),random.uniform(0,int(self.h)),self.w,random.uniform(1,10)))
            ui.set_color('green')
            self.lines[v].stroke()

How do I layer the UI elements to correctly reveal the bg undearneath?
I have set their alphas to 0.5 but I’m not seeing the bgLines view underneath.
Do I need to subview the elements that are on top to the bgLines view?

Any help appreciated

Thankyou! Exactly what I wanted - delay() was what I needed
