First Time calling SetAction does show the Brush tool's AM

ferdinand

Hi,

jeah, that is all very mysterious One possible solution could be to retrieve the BasePlugin via FindPlugin (as this seems to work) and write that node to the active object manager via ActiveObjectManager_SetObject, assuming you are just after setting an active tool without the implications CallCommand comes with.

One thing I forgot to mention is that when performing the SetAction the active tool is indeed the expected one. Except that the AM doesn't show it's attributes.

On the other hand when performing an ActiveObjectManager_SetObject with the BasePlugin obtained via FindPlugin I do indeed get the attributes shown in the AM of the baseplugin. However, at that point the desired baseplugin is NOT the active tool.
And doing both (SetAction and ActiveObjectManager_SetObject) does again set the desired tool, but the AM then shows the Brush tool attributes ... weird indeed.

It seems to be also reproducible with any tool. So, I tried with the ID_MODELING_ROTATE and obtain the same weird result ... but it reduces the amount of code needed to reproduce, as I can skip the whole DescriptionToolData and all its description resource files.

Reduced code below:

#include "c4d.h"

#define TEST_COMMAND1_PLUGIN_ID			1000001
#define TEST_COMMAND2_PLUGIN_ID			1000002

// ====================================
// CommandDatas
// ====================================

// MyCommand1 - does perform a CallCommand to active the DescriptionTool

class MyCommand1 : public CommandData
{
	INSTANCEOF(MyCommand1, CommandData)

public:
	virtual Bool Execute(BaseDocument* doc);
};

Bool MyCommand1::Execute(BaseDocument* doc)
{
	CallCommand(ID_MODELING_ROTATE);
	return true;
}

// MyCommand2 - does perform a SetAction to active the DescriptionTool

class MyCommand2 : public CommandData
{
	INSTANCEOF(MyCommand2, CommandData)

public:
	virtual Bool Execute(BaseDocument* doc);
};

Bool MyCommand2::Execute(BaseDocument* doc)
{
	doc->SetAction(ID_MODELING_ROTATE);
	return true;
}

// ====================================
// Plugin Main 
// ====================================
Bool PluginStart(void)
{
	ApplicationOutput("Test"_s);

	if (!RegisterCommandPlugin(TEST_COMMAND1_PLUGIN_ID, "CallCommand"_s, 0, AutoBitmap("Test.png"_s), "MyCommand1"_s, NewObjClear(MyCommand1)))
		ApplicationOutput("Test - failed registering CommandData");
	if (!RegisterCommandPlugin(TEST_COMMAND2_PLUGIN_ID, "SetAction"_s, 0, AutoBitmap("Test.png"_s), "MyCommand2"_s, NewObjClear(MyCommand2)))
		ApplicationOutput("Test - failed registering CommandData");

	return true;
}
void PluginEnd(void)
{
}
Bool PluginMessage(Int32 id, void * data)
{
	switch (id) {
	case C4DPL_INIT_SYS:
		if (!g_resource.Init())
			return false;
		return true;
	case C4DMSG_PRIORITY:
		return true;
	case C4DPL_BUILDMENU:
		break;
	case C4DPL_ENDACTIVITY:
		return true;
	}
	return false;
}

Hi I can indeed confirm your issue, However, I did remember we also faced this issue during the R22 dev cycle and it is now fixed.
I will get in touch with the development team to know if there is any workaround applicable to your code.

Cheers,
Maxime.

Dev team confirmed this issue is resolved as a side effect of the document mode merging in R22 but they didn't remember exactly why it happened.
I will try to take a look, but since there is an alternative (CallCommand, I know it is not optional because it screws the undo). I will put it as low prio on my side to look at and will be back (don't expect before the end of the week/start of next week).

Cheers,
Maxime.

@m_adam
Sorry to say but CallCommand is not an option, as in my specific case the DescriptionTool I want to activate is a hidden plugin, and CallCommand cannot execute hidden ones.
I understand the fact that CallCommand cannot call hidden plugins, and I don't assume this to be a bug. But if SetAction is an issue to use, and CallCommand doesn't execute as expected ... then what is one supposed to use?

ferdinand

Hm,

I never mentioned this, because I thought it is obvious, but since the thread has somehow come to a pass: Have you ever tried to exploit the fact that selecting two tools in row seems to solve the problem? I.e. first select some dummy tool and then the tool you actually want to select?

@zipit
I did try to activate a tool when initializing the plugin ... didn't make any difference.

But to answer your actual question, I just tried the following:

		doc->SetAction(ID_MODELING_ROTATE);
		doc->SetAction(ID_MODELING_MOVE);
		doc->SetAction(myPluginID);

Sadly, no difference, the brush tool still gets shown into the AM.

Hi,

I am not sure if we are talking about the same thing, ~~I meant (as extra lazy pseudo-code).~~

edit: Jeah, just like that. But you could try to give Cinema some time to catch up and invoke an EventAdd() or doc->ExecutePasses between the tool activations.

Hi @C4DS I tracked it down a bit.
First of all this issue appears only if you are in BodyaPaint Layout mode.

The main problem is that in R21 and previous versions, there is 2 tool logics (For BodyPaint and for Classic one) and more problematic, 2 different attribute manager, while in S22 there is only 1 attribute manager.

The issue in R21 is that if there is no Mode selected, and you are in BP mode, SetAction assume that you want to define the BodyPaint Manager and command, so if you define previously the mode to a Polygon mode it will set is to the one you expect.

doc->SetMode(Mpoints);
doc->SetAction(ID_MODELING_ROTATE);
SyncMessage(EVMSG_TOOLCHANGED, ID_MODELING_ROTATE);

Defining the Mode to a modeling mode and make sure to also send EVMSG_TOOLCHANGED this way the internal state of command manager for BP will also be updated(otherwise you may see the command jump).

Cheers,
Maxime.

@m_adam said in First Time calling SetAction does show the Brush tool's AM:

Nope!
I am simply starting the application in its default state. The default startup layout, with the default move tool selected.

However, I agree that in the default state the Object Model mode is active So, if I indeed perform a mode change to set it to points (probably also edges or polygons will work) I can see the SetAction bringing the expected tool settings in the AM.
So, this might be a solution:

Switch mode to points/edge/polygon
SetAction
Switch to orginal mode

C4DS

This works:

		const Int32 currentMode = doc->GetMode();
// only change mode if current one is different from Mpoints, Medges, Mpolygons or Mpolyedgepoint
		doc->SetMode(Mpoints);
		doc->SetAction(MYTOOL_PLUGINID);
		GeSyncMessage(EVMSG_TOOLCHANGED, MYTOOL_PLUGINID);
		doc->SetMode(currentMode);

Thanks for the hint.

EDIT:
FYI, note that I have only tested this solution on R20, not R21, but I assume it will behave identical.

m_adam

And I did test only on R21 so be sure to check again because I wasn't able to reproduce as you said with default layout in R21.

I am using R21.207 and with default layout see the brush tool in the AM (identical to what happens with R20.059). For safety, I have now tested your solution on R21 and works as expected.
