1.x plugin development

[Jeff]

In GBPVR all keys used to go to the plug-ins OnKeyDown() handler. In PVRX2 Menu does not make it. I've tried it in both my new weather plug-in and in the old video archive plug-in. I hope your "out of town" is for fun not work.

Yeah, fun not work. A bit of a mid-winter christmas get together with the family - thought that PC and broadband connection I organised for my mother in law is proving useful for killing a bit of downtime. (need my internet fix every so often)

Does the config app look for config forms of the new style plugins? The new version of International Cinema has a GetConfigFormInstance() method but the settings button on the config app stays disabled.

I used to be able to use sharp develop to convert examples from c# to vb and it worked flawlessly. I have seen that PVRx2 is far more critical of errors

to get the hello world example working I have had to change a few things, it didnt like the sub handlePopupCallback(ByVal popup As Object, ByVal command As String) without me addind Implements IUiPopupCallback.handlePopupCallback at the end.


Also warnings of double to string now stop the plugin from working here is an example from hello world.

this is the conversion:

item.AddProperty("@name", "some name " + i)
item.AddProperty("@filename", "item.png")
item.AddProperty("@someContextInfo", "item:" + i)

The first line has a warning of "implicit conversion from string to double"
The third line has a warning of "implicit conversion from string to double"

By changing the lines to the following:

item.AddProperty("@name", "some name " + CStr(i))
item.AddProperty("@filename", "item.png")
item.AddProperty("@someContextInfo", "item: " + CStr(i))

This removes the warnings and the plugin now works in VB, prior to this it would enter, then flash up the left hand buttons and then drop back to the main menu. the error report in the log file looks like this:

========================

Is PVRx2 set to fail on more errors than GBPVR?

I am also getting a confused with what should handle the key presses when I select an item from the left-hand list; is it OnKeyDown, handleCommand or something else?

These are my initial findings from a VB perspective, I do appreciate that I am far in the minority by developing in VB and not c# but cant be bothered changing to c# as I am not likely to use it for anything other than GBPVR.

Cheers

Yes, it looks in subdirectories. If you bump this thread in a couple of days, I'll take a look when I'm back home.

I dont think this is PVRX2 failing, but rather your C# to VB.Net conversion getting it wrong. The stack trace shows some conversion error occurring in your implementation of the PopulateListWidget() method. Unfortunately I'm no expert in VB.Net, so cant tell you the exact format for what these lines should look like.

at GameZone.GameZone.GameZoneTask.PopulateListWidget() in H:\GB-PVR\GBPVR1.x\GameZone v3.0\plugins\GameZone\Source\GameZone.vb:line 42

So what exactlly is one line 42?

If you want to attach your VB converted sample, I'll see if I can find the cause for you.

[McBainUK]

Don't worry it was my fault - was doing the age old trick of trying to use the pluginhelper in the config form.

Line 42 was the first string to double line. so thats fine now I worked that out by converting the integer to a string (CStr), still not sure how to get the information from a selected list item. I used to pass all my key presses onto gbpvrUiElements_OnKeyDown, I think once I have that I can start the conversion process. imcidentally the first thing that doesnt work when you try GameZone in PVRx2 is that selecting a game in the list drops you out back to the main menu, I was wondering if the keymappings file needs moving as well as the plugin dll?

Its recommended to have a keymappings file for anything but the basic keystrokes (up/down/left/right/ok etc), but lack of that shouldnt be the cause here. If you reproduce the problem and attach the logs I'll take a look.

Is there something different about PVRX2's invocation of the needsRendering() method? My plugin produces the following (repeated about a zillion times) in the PVRX2.exe.log:

Code:

2007-07-16 12:44:20.218    ERROR    [1]    Unexpected error: System.NullReferenceException: Object reference not set to an instance of an object.
   at UbuStreamPlugin.UbuStreamPluginTask.needsRendering()
   at GBPVRX2.MenuTask.x0be92cb4e3ac1817.needsRendering()
   at GBPVRX2.MenuTask.xd2a3a83a17aec615.needsRendering()
   at GBPVRX2.x0061b801bdf12d35.xdb012c437aec4a40(Boolean xd23bf32f3b17e3be)
   at GBPVRX2.xb979ad394703258e.xfb409e85bd292293(String[] xf18a926310372520)

I don't have very much going on in the offending method:

Code:

public bool needsRendering()
        {
            if (menuButtons.Result != null) return true;
            // Add UbuStreamPluginTask.needsRendering implementation, if needed
            if (renderRequested == true)
            {
                renderRequested = false;
                return true;
            }
            return false;
        }

menuButtons is initialized in the Activate() method. renderRequested is a class variable that's initialized to false. What could go wrong?

I'm experiencing "hardware hell" at the moment so don't have a 1.0.08 environment set up. But two people have reported getting the same message in their logs (followed by the white screen of death with the dreaded red X). I'm a bit tired (from repeatedly hitting my NIC card with a hammer and shouting at it) so I may be missing something obvious here, but I'd sure appreciate any ideas.
