vtrix: Yes that's a plugin-bug. I've seen that bug now too.. I'll work on it asop..

Construct version?

Chrome version?

I cannot confirm this. The 'Preview' works fine in r85,r86

and Chrome (20.0.1096.1 dev-m), also in Firefox (11.0)

+) Do you have a firewall (that blocks this port or blocks a local webserver)?

+) Perhaps changing the preview port helps - perhaps other software use that port?

+) Have you used a custom plugin? If this throws an exception it can happen that nothings works..

What logs are in the Chrome-console? [(CRTL)+(SHFT)+ (I) in Chrome]

vtrix: It's difficult to find the bug without knowing your project in details.

I don't know if or how your used library "FileSaver.js" influences the c2 runtime (painting-threads). As far as I've found out during developing this plugin, it's texture has to be "painted" on the construct-canvas (as a blank-image should be possible - the users doesn't see it but it is not "invisible" [in real] ;) ) because some browsers doesn't update the canvas-graphics without a runtime (plugin) redraw. You haven't uploaded the fallback script - so on android-webkit it wont work (but desktop-browsers should have no problem).

Which Construct release have you used? I haven't testet the plugin with the newest beta r86 - it shouldn't have problems with it but I cannot proof it for now.

What do you try to save? Text-objects and objects that are not drawn on the canvas cannot get saved.. sprites on different layers should work-perhaps better with the canvas2d renderer - I suppose but I haven't tried..

What do you want to do with that file? Only reading its content or modify it?

If you want to read its content then the easiest way is using a custom plugin like load Json or csv.. in the plugin thread are examples how to do that.. <img src="smileys/smiley1.gif" border="0" align="middle" />

Two possible ways

-) ajax - read it with php

-) custom plugins: file reader, csv, Json, call js

Depends on where is the file, on the server or at the user..

Ajax tutorial to make you familar with the ajax plugin

--> How Do I - Frequently asked questions - "Ajax" - linked examples..

In the linked post is a screenshot of the javascript lines.. but sending score and.. is very easy with the built in ajaxplugin or if you want pass it per post with a custom ajaxpost plugin.. <img src="smileys/smiley2.gif" border="0" align="middle" />

You have many possibilities for that:

With the Id property

or easier directly with ajax or ajaxpost plugin..

There are some examples linked in the howto faqs<img src="smileys/smiley2.gif" border="0" align="middle"> and a tutorial for the ajaxplugin..

It should be possible when modifying the runtime.js:

Copy all codelines that live in the method acts.LoadJSON to the instance-constructor after the variable-initalisation: "instanceProto.onCreate"

I'll look to this plugin asap - and then make a new release. If you're faster than me and want to share it - post it and I'll link it in the first post.

Why I have done the loading with an action? My idea was, that it should be possible to reload the JSON-file whenever wanted. It should possible to modify it per ajax and the reload the new JSON-data with then plugin. <img src="smileys/smiley2.gif" border="0" align="middle" />

Does it work when you move the sprite with two actions to another place and then back? Should force two redraws - I suppose.

History - c2i:

[Update3] c2i - v 1.3:

1) The php-file 'createImg.php' gets now created from C2 when exporting the project.

2) Demo - changed: The demo-project is forced via the project-properties to use the canvas2d renderer. --> should work now properly on whatever.

[= current workaround to avoid the WebGL-bug - see posts on side 2]

3) Refactored plugin-sourcecode - no improvements to recognize during edittime but the plugin has now fewer codelines and works as the last release.

Demo - canvas/sprite/screenshot + Plugin(v 1.3)+capx

____________

[Update2] c2i - v 1.2:

Screenshots are possible now

Demo - canvas/sprite/screenshot + Plugin(v 1.2)+capx(WebGL renderer - if possible)

Known bug: WebKit+WebGL:

If WebKit-Browsers(Chrome) are forced with the setting in the project-properties to use the WebGL-renderer they create only blank images. Firefox has no problem with WebGL enabled.

Workaround for now: Use the "canvas2d" renderer. This should work on whatever..

[/Update2]

____________

[Update] c2i - v 1.1:

Now the saving of Base64-Strings to images is possible. Together with Pode's behavior "Extract Sprite to base64 string" it's possible to save sprites to images.
