Irredit plugins.

[3DModelerMan]

Hi, I'm working on a plugin for Irredit so that I can add my custom scene node to it. I'm kinda confused on one part though. When I program the plugin. Do I include the same scene node implementation I use in the game? Or do I make some sort of custom one only for in Irredit?

[sudi]

well that depends in irredit u actually only need a placeholder node that writes the correct name to the irr file. in your programm u can spawn a totally different scenenode with just the same name.

So I can't save a custom scene node so that I can edit properties in Irredit? I thought that I needed to make some sort of node in the Irredit plugin and also a node factory, that deals with the same type of node. Then have the same two things in my program, a node and a node factory. Am I missing something there?

Of course u can do that. and yes you will need a node factory in irredit and also in your programm when u wanna use loadScene(..).
But they don't have to be the same classes. thats what i wanted to say.

[3DModelerMan]

Oh okay. How are the node factories associated with one another? The types returned by getType()?

Well ... I am using the same code for my plugins that I use for the game(s). There are just some #ifdefs to disable certain things, this way I can also use the same scenenodefactories. If you want more details you could look at the factory in my IrrOde wrapper.

[3DModelerMan]

Oh, okay. Can you do custom scene node animators?

yes

I tried compiling my plugin but it didn't work in Irredit. It said "Can't find entry point" or something like that. I'm compiling my plugin with Irrlicht 1.7.1 though. Do I need to compile with 1.5? Or does anyone here have a redistribution license and would be willing to recompile for Irrlicht 1.7.1? I've basically copy and pasted the entry point function in the ExamplePlugin.cpp file, I only changed typenames to match my scene nodes and factories. I didn't see any function declaration in ExamplePlugin.h for the entry point function, it's only supposed to be in the .cpp file right?

[Brainsaw]

Which compiler are you using? You have to compile IrrEdit plugins with VC++, otherwise they won't work (sad but true).

You have to compile with the irrlicht version that is included with irrEdit. check out the plugin examples. maybe just usem them as a base and add your own code. And like Brainsaw said, you have to use VisualC++

[3DModelerMan]

Yeah I'm using VC2008 and I'm gonna upgrade to 2010.

It works, the plugin loads in Irredit. The only problem is that I have the serializeAttributes and deserializeAttributes functions both implemented, in both the plugin node and the regular node, but nothing shows up under "node specific" in Irredit.

[3DModelerMan]

This is my code

Code: Select all

void CLevelEndCheckpoint::serializeAttributes(io::IAttributes* out, io::SAttributeReadWriteOptions* options)
{ 
 ISceneNode::serializeAttributes(out, options);
 out->setAttribute("Radius", m_radius);
 out->setAttribute("Box", m_boundingBox);
 out->setAttribute("Next_checkpoint_ID", m_nextID);
 out->setAttribute("Load_level_filename", *m_levelFilename);
 out->setAttribute("Script_filename", *m_scriptFilename);
}
void CLevelEndCheckpoint::deserializeAttributes(io::IAttributes* in, io::SAttributeReadWriteOptions* options)
{
 ISceneNode::deserializeAttributes(in, options);
 m_radius = in->getAttributeAsFloat("Radius");
 m_boundingBox = in->getAttributeAsBox3d("Box");
 m_nextID = in->getAttributeAsInt("Next_checkpoint_ID");
 *m_levelFilename = *in->getAttributeAsEnumeration("Load_level_filename");//Watch these for errors.
 *m_scriptFilename = *in->getAttributeAsEnumeration("Script_filename");
}

curious... what custom scene node are you creating? i see clevecheckpoint, and reading through it it makes me believe this is an entry point to a new level? j/w ..
