API : HotlinkNode Element and database

Anonymous — Fri, 04 Aug 2023 12:49:24 GMT

Hello,

i'm trying since last month to write a plugin which load an external Hotlinked Module and place it on the project.

I'm near the end , i'v loaded the module, assigned it to an element but i don't succeed to place it on the project.

Here is my little fonction :

API_HotlinkNode myAPI_HotlinkNode;
	GSErrCode err;
	IO::Location  location("c:\\test.MOD");
	API_Guid myAPI_HotlinkNodeGuid;
	API_Element element;
	API_ElementMemo memo;

/***************************************************************************************************/
/******************************REMPLISSAGE DE LA STRUCTURE******************************************/
/***************************************************************************************************/
	BNZeroMemory (&myAPI_HotlinkNode, sizeof (API_HotlinkNode));

	//Charge le module en mode unique (define single story mode)
	myAPI_HotlinkNode.storyRangeType = APIHotlink_SingleStory;
	//Precise les que les extensions possibles sont :.pln, .mod, .plp or .2dl file. (define file type)
	myAPI_HotlinkNode.type = APIHotlink_Module;
	//Définie le fichier à charger (define file to load)
	myAPI_HotlinkNode.sourceLocation = &location;
	//definie l'étage comme étant l'étage -2
	myAPI_HotlinkNode.refFloorInd = -2;

	CHANSI2Unicode ("Module 1", GS::CStringLen, myAPI_HotlinkNode.name,API_UniLongNameLen, CC_Default, NULL);      

/***************************************************************************************************/
/******************************FIN REMPLISSAGE DE LA STRUCTURE**************************************/
/***************************************************************************************************/

/********************CREATION DU GUID*************************************/
	err = ACAPI_Database (APIDb_CreateHotlinkNodeID,&myAPI_HotlinkNode,NULL,NULL);
	if (err != NoError) {
			afficheMessage("HotlinkNode parameter is NULL or sourceLocation is NULL or invalid",err);
			return err;
		}
/*************************************************************************/
	myAPI_HotlinkNodeGuid = myAPI_HotlinkNode.guid;


/********************MISE A JOUR DU CACHE*********************************/
	err = ACAPI_Database (APIDb_UpdateHotlinkCacheID,&myAPI_HotlinkNodeGuid,NULL,NULL);
	
	if (err != NoError) {
			switch(err)
			{
			case APIERR_BADPARS:
								afficheMessage("hotlinkNodeGuid parameter is NULL",err);
								break;
			case APIERR_BADID:
								afficheMessage("hotlinkNodeGuid is invalid",err);
								break;
			default:
					afficheMessage("APIDb_UpdateHotlinkCacheID",err);
					break;
				
			}
			return err;
		}
/*************************************************************************/
/******************PLACE LE MODULE LIE DANS LA DATABASE*******************/

err = ACAPI_OpenUndoableSession ("Place le module");
if (err == NoError) 
{
	BNZeroMemory (&element, sizeof (API_Element));		
	element.header.typeID = API_HotlinkID ;
	element.header.index = 1;
	err = ACAPI_Element_GetDefaults (&element, &memo);
	if (err == NoError) 
	{
		element.hotlink.type = APIHotlink_Module;
		element.hotlink.hotlinkNodeGuid = myAPI_HotlinkNodeGuid;
		err = ACAPI_Element_Create(&element, &memo);
		if (err != NoError)
		{
			switch(err)
			{
				case APIERR_BADPARS:
									afficheMessage("The passed parameter is NULL; element",err);
									break;
				case APIERR_BADID:
									afficheMessage("The element type is invalid, or the element type is not supported by the server application",err);
									break;
				case APIERR_BADDATABASE:
									afficheMessage("The current database is not proper for the operation",err);
									break;
				case APIERR_REFUSEDPAR:
									afficheMessage("The element->header.typeID parameter was incorrect. It might happen if you want to create something in a window not capable to display it, for example a wall in a section window. ",err);
									break;

									break;
				default:
						afficheMessage("ACAPI_Element_Create",err);
						break;
			}
			return err;
		}
		err = ACAPI_Database (APIDb_RedrawCurrentDatabaseID,NULL,NULL,NULL);
		if (err != NoError)
			afficheMessage("APIDb_RedrawCurrentDatabaseID",err);
		ACAPI_DisposeElemMemoHdls (&memo);
	}
	else
		afficheMessage("ACAPI_Element_GetDefaults",err);
	
	ACAPI_CloseUndoableSession();
}
else
	afficheMessage("ACAPI_OpenUndoableSession",err);

if someone would know the thing i forgot to do, thank you in advance for your help.

Is an error returned at any point in this function? If so, where, and which error code?

Hello,

not any error is returned, that's why I really don't know what is missing.

Check the easy things first - have you checked the storey (floor) and layer applied? And what does the transformation matrix contain?

I allready checked the floor, but i do not filled the transformation matrix, I thought it was not needed.

Do I have to fill it like this :

element.hotlink.transformation.tmx[3] = 10;
			element.hotlink.transformation.tmx[7] = 4;
			double	co = cos (0.52359877556);
			double	si = sin (0.52359877556);
			element.hotlink.transformation.tmx[0] = element.hotlink.transformation.tmx[5] = co;
			element.hotlink.transformation.tmx[1] = -si;
			element.hotlink.transformation.tmx[4] = si;

about the layer is it this :

element.header.layer = 1;

THANK YOU VERY MUCH .

It works thanks to you, had to fill the layer.

I thank you very much.

Do you know if we have to ask for a validation to graphisoft before to sell a plugin, or to do something else?

Yes, you need a developer ID from Graphisoft to enable the add-on to work with the commercial version of ArchiCAD. Take a look at the information here: http://www.graphisoft.com/support/developer/policy/index.html
