A little help ? (1 Viewer)

Hi!
This look like fun, so I tried to do something simple. Adding the dll, and the property that is it use is : #ImagePlugin.Image

Place the plugin i process plugin folder. Changing picture every 20s. Needs a folder C:\ProgramData\Team MediaPortal\MediaPortal\ImagePlugin

Pasting source soon.[DOUBLEPOST=1420896086][/DOUBLEPOST]Ther is nothing random at all here, but that should be easy to fix. Place your images in the above mentioned folder ImagePlugin

If i create a project and add your source code i get
Error 1 The type or namespace name 'Config' does not exist in the namespace 'MediaPortal.Configuration' (are you missing an assembly reference?)

Error 1 The type or namespace name 'Config' does not exist in the namespace 'MediaPortal.Configuration' (are you missing a

You need to reference Utils.dll (located in Mediaportal install location)

 

[wizard123]

Ahh i see thankyou

 

[Ministerk]

And if you read the you might notice that I shamelessly stole parts of LoadFolder() method from GuiMultiImages, hence some out off place comments... I also did
this beauty:

if (_fileList.Count() > 0)
    _directoryLoaded = true;

// Can (should??) be simplified to:
//_directoryLoaded = _fileList.Count() > 0;

Hence it tries to load images until there is any in the ImagePlugin folder. Remove this statement if you only would to try once. And set _directoryLoaded = true; instead.

 

[wizard123]

Thanks, it's far more complicated than i was expecting lol. I have your code working as plugin now i just want to make the images random and to fade between it baffles me with all the public voids and methods etc lol.

 

[Ministerk]

With the fading stuff I would add another property and alter the property to set

Eg:
Odd _currentImage:
GUIPropertyManager.SetProperty("#ImagePlugin.Image.1", _fileList[_currentImage]);
GUIPropertyManager.SetProperty("#ImagePlugin.Image.2", " "); //Note the space!
Even _currentImage:
GUIPropertyManager.SetProperty("#ImagePlugin.Image.1", " ");
GUIPropertyManager.SetProperty("#ImagePlugin.Image.2", _fileList[_currentImage]));

And add visibility condition:
for the one showing #ImagePlugin.Image.1:
<visible>!string.equals(#ImagePlugin.Image.1,)</visible>
and #ImagePlugin.Image.2:
<visible>!string.equals(#ImagePlugin.Image.2,)</visible>

 

[Ministerk]

I tried it myself, changed to this:

GUIPropertyManager.SetProperty("#ImagePlugin.Image.1", (_currentImage % 2 != 0) ? " " : _fileList[_currentImage]);
GUIPropertyManager.SetProperty("#ImagePlugin.Image.2", (_currentImage % 2 == 0) ? " " : _fileList[_currentImage]);

and used this in skin:

    <control>
      <description>Imageplugin</description>
      <type>image</type>
      <id>0</id>
      <posX>123</posX>
      <posY>360</posY>
      <width>200</width>
      <height>200</height>
      <texture>#ImagePlugin.Image.1</texture>
      <animation effect="fade" time="300">visible</animation>
      <animation effect="fade" time="300" delay="300">hidden</animation>
      <visible>!string.equals(#ImagePlugin.Image.1,)</visible>
    </control>
    <control>
      <description>Imageplugin</description>
      <type>image</type>
      <id>0</id>
      <posX>123</posX>
      <posY>360</posY>
      <width>200</width>
      <height>200</height>
      <texture>#ImagePlugin.Image.2</texture>
      <animation effect="fade" time="300">visible</animation>
      <animation effect="fade" time="300" delay="300">hidden</animation>
      <visible>!string.equals(#ImagePlugin.Image.2,)</visible>
    </control>

Worked alright.

 

[wizard123]

Just tried it, works great thank you
Out of interest what does the c# section do ? i would really love to learn c# but struggling to take it in.

 

[Ministerk]

It's an inline if-then-else statement:
Eg:
string hello = booleanStatement ? "Hello booleanStatement is true!" : "Hello booleanStatement is false!";

% is the modulo operator. If you take modulo 2 of an integer, odd numbers evaluates to the value 1 and even numbers the value 0

 

[Ministerk]

Hi again. Did get some time to check this random/shuffle stuff also:

You could do like this:

// This is already in the TimerProc method:
if (_currentImage >= _fileList.Count())
     _currentImage = 0;

//Add this shuffles the list if _currentImage is 0
if (_currentImage == 0)
    _fileList = _fileList.OrderBy(x => Guid.NewGuid()).ToList<string>();

This will shuffle the images every time _currentImage is zero => shuffles the images every time all in the collection has been shown.
