Ghostly icons?
-
In a <Scene> script that places a series of emojis on the Node, it seems that even after I have removed the images, their ghost still remained.
I have solved the issue by the use of z-position.
But I can’t figure out why something that is removed and not visible, can be found on the node?
Any ideas?Also any one know how I can access the iPads emojis?

@adrius42 iPads emojis are characters, not images
-
So more, properly any ideas on changing a character to an image?

i could not reproduce your "ghosts", though you had some logic errors related to restarting touch -- for instance, you needed to set touched_emojis to None in check_collisions otherwise you kept moving it, and you needed to reset touch in touch_ended. that might make you think there is a ghost stealing touches.

@JonB you are just amazing Thankyou!

@adrius42 Up to you for list, names, size and position, this is only an example:
class Object (SpriteNode): def __init__(self, img, col=0, row=0): if img == 'emj:Alien': with ui.ImageContext(64,64) as ctx: ui.draw_string('🤠',font=('Menlo',64)) img2 = Texture(ctx.get_image()) else: img2 = img SpriteNode.__init__(self, img2, position=((col-0.5*col)*190+60, (row-0.5*row)*152+200))
