Beta Status Update

@JonB here is the code I'm using now, have restarted Pythonista many times and can't think of any other changes I've made other than removing light.alpha = 1:

# coding: utf-8

import sk
import random

MAXSPD = 700
MAXLIFE = 10
TEXTURE = 'shp:Circle'
MINLIFED = -120
MAXLIFED = 120
SCALE = 2

decayrate = 0.005
collider_f = 0.3

def randvec(maxspd):
    return (random.randint(-maxspd, maxspd), random.randint(-maxspd, maxspd))

particle_tpl = sk.SpriteNode(sk.Texture(TEXTURE))
particle_tpl.name = 'particle'
particle_tpl.color_blend_factor = 1
particle_tpl.age = 0
particle_tpl.lighting_bit_mask = 1
particle_tpl.x_scale = SCALE
particle_tpl.y_scale = SCALE
particle_tpl.alpha = 1
particle_tpl.shadow_cast_bit_mask = 1
physics = sk.PhysicsBody.circle(particle_tpl.size.x/2 * collider_f)
physics.restitution = 1.2
physics.affected_by_gravity = False
physics.allows_rotation = True
physics.mass = 0.3
physics.pinned = False
physics.angular_velocity = 0
physics.category_bit_mask = 1
physics.contact_test_bit_mask = 1
particle_tpl.physics_body = physics

class Game (sk.Scene):
    def __init__(self):
        sk.Scene.__init__(self)
        self.name = 'scene'
        self.img = sk.Texture(TEXTURE)
        self.maxspd = MAXSPD
        self.handles_node_touches = False
        self.maxlife = MAXLIFE * 60  # convert to frames
        self.background_color = (0, 0, 0)
        self.lighting_bit_mask = 1
        
        # init walls
        walls = sk.Node()
        walls.position = (0, 0)
        physics = sk.PhysicsBody.edge_loop_rect(0, 0, 1024, 768)
        physics.dynamic = False
        physics.restitution = 1.1
        walls.physics_body = physics
        self.add_child(walls)
        
        # lighting
        light = sk.LightNode()
        light.position = (10, 758)
        light.shadow_color = (1, 0, 0)
        light.ambient_color = (0, 0, 1)
        light.light_color = (0, 1, 0)
        light.enabled = True
        light.category_bit_mask = 1
        light.falloff = 1
        light.name = 'light'
        self.add_child(light)
    
    def update(self):
        for p in self['particle']:
            p.age += 1
            if p.age >= p.lifespan:
                # if exceeded life, reduce alpha by 1
                p.alpha -= decayrate
                if p.alpha <= 0:
                    p.run_action(sk.Action.call(p.remove_from_parent))
    
    def touch_began(self, node, touch):
        self.selected = None
        new = particle_tpl.__copy__()
        new.physics_body = new.physics_body.__copy__()
        new.lighting_bit_mask = 1
        new.position = touch.location
        new.physics_body.velocity = randvec(MAXSPD)
        new.color = (random.random(), random.random(), random.random())
        new.lifespan = self.maxlife + random.randint(MINLIFED, MAXLIFED)
        new.alpha = 1
        self.add_child(new)
    
    def touch_moved(self, node, touch):
        self.touch_began(node, touch)
    
    def did_begin_contact(self, collison):
        if collison.body_a.node.name == 'particle' and collison.body_b.node.name == 'particle':
            collison.body_a.node.color = (random.random(), random.random(), random.random())
            collison.body_b.node.color = (random.random(), random.random(), random.random())

def main():
    game = Game()
    scene_view = sk.View(game)
    scene_view.shows_fps = True
    scene_view.shows_node_count = True
    scene_view.present()
    return game

if __name__ == '__main__':
    g = main()

However, it still just gives me a black screen. As before, when I touch the screen the node count goes up but I cannot see anything.

I can see the balls appear just fine with your code on ios 8.2 on ipad2. For the platformer game I had a similar problem which was solved by rotating the display. You might try running it, then rotating the device so that it tries to resize.

The code above works for me.

Not sure if this is a bug or an odd feature, but Pythonista strips all whitespace (including trailing newlines) from the end of a file when it is saved. This only becomes apparent when closing the editor tab for that file or restarting the app. If this is intentional, it would be nice if this were optional.

In the beta release ui.View().present(orientations=['landsacpe']) is not forcing the view to display in landscape mode. It is just me or are others seeing the same behavior?

Can somebody among the beta users tell me whether the extensions can be made to handle files (e.g., Mail attachments) in a way that was possible with Open In?

The scenario I used in the days of Open In was this: I have an email attachment of specific type (e.g., .txt), I open it in Pythonista, the Open In handler then performs some automated actions (in my case, uploads it via SCP and then runs several commands on the remote server). Can this be done with the extensions now? Should I wait for the new release or try and find other ways to do this?

JonB

That's exactly what the extensions let you do.

How can I sign up for the test flight beta? I want to try it, looks AMAZING.

userista

Modules that are in site-packages are not importable when in the app extension. Is this expected behavior?

JonB

The extension runs in its own sandbox.. As I recall there was an extensions site packages? You have to separately install packages to both locations.
