hi,
sorry I was focused on calling a command and not a script.
Even if it's pretty simple, it's not as simple as i expected to run a python script, sorry about that.
Be careful that you need to create the script and relaunch c4d to be able to find it by its name.
The idea is to retrieve the ID of the script and use callCommand to execute it. (as you can do with any commandData IDs)
you can retrieve the ScriptList with GetScriptHead witch return a GeListHead
So you can retrieve the first with GetFirst and compare the name.
If you find one, you can simply return it's IDs using GetDynamicScriptID and return it.
You now just have to use CallCommand with this ID. (be aware that this CallCommand will create an undo step in the undo stack)
So your script will be executed when a new document is loaded.
#include "maxon/apibase.h"
#include "maxon/errorbase.h"
#include "maxon/errortypes.h"
#include "maxon/file_utilities.h"
#include "maxon/application.h"
#include "c4d_general.h"
#include "c4d_commanddata.h"

#include "c4d_baselist.h"
static Int32 GetScriptID(const maxon::String& scriptName)
{
iferr_scope;
// check all script
// Retrieves the script head
BaseList2D* scriptHead = static_cast<BaseList2D*>(GetScriptHead(0)->GetFirst());
// for all script
for (BaseList2D* script = scriptHead; script != nullptr; script = script->GetNext())
{
// retrieves the name of the script
maxon::String name = script->GetName();
// if the name match the argument, return the id of the script
if (name.IsEqual(scriptName))
return GetDynamicScriptID(script);
}
// return NOTOK if no script founded.
return NOTOK;
}
class pc12835_scenehook : public SceneHookData
{
public:
static NodeData* Alloc() { return NewObjClear(pc12835_scenehook); }
Bool Message(GeListNode* node, Int32 type, void* data) override
{
if (type == MSG_DOCUMENTINFO)
{
DocumentInfoData* const msg = static_cast<DocumentInfoData*>(data);
if (msg == nullptr)
return false;
// switch message sub-type
switch (msg->type)
{
case MSG_DOCUMENTINFO_TYPE_LOAD:
{
// define my script name
maxon::String scriptName = "myscript"_s;
// search the ID of the scrip
const Int32 scriptID = GetScriptID(scriptName);
// if the script have been founded, execute it.
if (scriptID != NOTOK)
CallCommand(scriptID);
break;
}
case MSG_DOCUMENTINFO_TYPE_UNDO:
case MSG_DOCUMENTINFO_TYPE_REDO:
{
ApplicationOutput("undo or redo done"_s);
break;
}
}
return true;
}
return SceneHookData::Message(node, type, data);
};
};
Of course you need to register your sceneHookData with RegisterSceneHookPlugin
Cheers,
Manuel
