For background.

Here is a running C2 app I am trying with crosswalk. paint2.pixarra.com

This runs properly with Chrome and Firefox on desktops and on Android devices.

Exported for Android (XDK Crosswalk) using C2 158.2.

Packaged with Intel XDK according to instructions.

Installed the apk on the device.

The basic layout is correct. Touch events appear to be triggered wrong. A quick touch is triggered as 2 touch events. However, a slow tap and then release is seen as a single touch event.

The canvas (modified canvas plugin) seems to be working incorrect or perhaps the scripts using it are flaking out.

Tried on 2 different devices with same results.

What is interesting is I went and installed the Android SDK and USB device driver for my device and ran in debug mode from the XDK and it ran properly on the device in that case. That gives me hope that the issue is a minor one.

Also code was minified in all cases (working and not working) so I don't think that is the issue.

Any ideas??

Thanks,

Ken

Hopefully with a working link this time.

Thanks causenad, yes the mirror option was added in the recent update on request from my daughter, was quite easy to add that feature in.

The saving of image files and possibly sharing of images up to social media location has been and remains a difficult part. File saving is not consistent at all on mobile platforms but does seem to be handled well on desktops. I haven't explored yet how to upload images to social media sites but yes that would be a great addition. It seems most of the APIs for that are not geared towards javascript so perhaps I would need s server component to reform the image data and push it to various sites. If anyone has info or experience with doing this it would be great to hear.

Once I'm a bit more happy with the core functionality in the program I will explore other destinations such as facebook.

Thanks about the smoothness! I have been surprised how well Javascript can do if you are careful. This latest version even runs well on a Samsung Galaxy Note II.

Thanks for your feedback Joannak! Indeed, Construct 2 is a very good platform and for those who aren't afraid to tinker in the plugin code area it opens it up more of course.

Thanks,

Another update version 1.3. Performance improvements are the main thing here.

For this kind of program (painting) sacrificing screen redraw rate to keep other events being serviced makes a lot of sense. When painting (drawing) the screen redraw rate is forced down to 10 frames a second rather than the default that it tries to maintain at 60 fps. This allow slower devices (tablets for example) to process more stroke functionality resulting in smoothing strokes. Quite a big difference in quality for non-desktops.

Luckily it wasn't too hard to force a lower fps rate. Just had to override the runtime.redraw flag (force it FALSE) that was getting set by a number of different plugins and then set it TRUE on my own schedule.

One surprise was that the sprite position action was setting the redraw flag to true even for invisible sprites.

I should add a thank you to Ashley if you should happen to read down to here. Fine work on Construct 2. Very robust without a single crash and some things with the layout UI are well thought out and make tweaking and positioning of objects quite efficient as well and the nice drag features in the event sheets.

Thanks!

Ken
