addTextSceneNode - great feature, how do you delete it?

So, I find this great feature addTextSceneNode.

The text from addTextSceneNode is persistant which means that the text stays on the screen (and in the engine) even after the endScene is called (unlike the 2D text). Now I want to DELETE the node (ITextSceneNode) but there is no way to do it..

Anyone know how?

BTW, addToDeletionQueue does not work.

I don't know what you mean by 2D Text, but a GUIStaticText also stays on screen until it is removed manually.

As the name says, A TextSceenNode is a SceneNode, you remove every SceneNode by simply calling ISceneNode::remove().

Hope, that helps.

Hmmm, well:

Code: Select all


scene::ITextSceneNode *MyTextNode=NULL;

MyTextNode = smgr->addTextSceneNode(font,str.c_str(),SColor(0, 255, 128, 128),0,LabelX,1);

MyTextNode->remove();

The MyTextNode->remove(); doesn't work. Matter of fact, it won't compile. I have even tried to type cast it with ISceneNode and that doesn't work either.

The compiler (MS VS 6.0) gives the following error:
error C2227: left of '->remove' must point to class/struct/union

Any other suggestions?

Make sure your node is still in scope when you call the remove() function!

If you make it invisible then there is no overhead because it isn't drawn and you can reuse it.

MyTextNode->setVisible(false);

Then just put true in there if you want it to be drawn again.

calling remove() or anything else on the node wont work because the ITextSceneNode class doesnt have an implementation outside Irrlicht.

the only declaration of the ITextSceneNode in the Irrlicht headers is
class ITextSceneNode;

Yea I need to know the answer to this as well. Have you figured it out?

I notice in ITextSceneNode.h there is a setText command but I can not call it... it gives me a build error saying: user of undefined type 'irr:scene:ITextSceneNode'

Is the header never included anywhere? If not then where can I put it?

Nm I'll just make my own class to encompass Font->draw()
