Displaying text and debugging

[Raff1]

Hi! I am trying to display and update some text on the screen to read out some values for control and debugging. I am currently using
virtual IGUIStaticText = gui::IGUIEnvironment->addStaticText()
to do this. The text displays as it should, but I don't know how, or if its possible to edit the text contents. Since it is a static text class, I guess this is not the favorable way to do this anyways.

So what is the best way to display text I can easily update?

*Edit. Found some sticky information about debugging software i will be looking into.

You can change the text from your app, but it's not meant to be edited by the user of the app (in contrast to editbox)

Okey, thats just what I need. But my question is how I can change the text from the app. I could not recognize any function for that in the API.

setText should be the way, unless I'm confused with other APIs.

I am very new to irrlicht, I have the same problem to show dynamica text, may I ask that what object/class is "setText" belongs to?

setText is for static text.
static text doesnt mean that it can only have one value always, but means that the user can't change it.
you can change it any time from your app.

myText->setText(L"MyText");

myText->setText(L"MyText");

sorry for another stupid question....

I have no idea about where is "myText" comes from ?

so how can I display text by using my own defined variables ?
for example, I would like to display the name of some ISceneNode object on screen.

Code: Select all

ISceneNode* cube = smgr->addCubeSceneNode(50);
cube -> setName("cube");

guienv->addStaticText( smgr->getSceneNodeFromName("cube")->getName() , rect<s32>(10,10,260,22), true,false,0,1,false);

I get big error this way.
Can anybody kindly show me how to fix this?

THX a lot

big error is not what I'd call a descriptive explanation. Please make sure you understand the basic C++ things needed for this situation, and post the full compiler message if you cannot figure it out.

here is the error I got:

Code: Select all

ERROR	31	error C2664: 'irr::gui::IGUIEnvironment::addStaticText' : cannot convert parameter 1 from 'const irr::c8 *' to 'const wchar_t *'	d:\_development\irrlicht\_lab\57_proto_game\src\src\main.cpp	178	57_proto_game

I am also a newbie to c++ ... T_T

I realize that I need to convert c8 to wchar_t , I have already spent couple hours searching the solution, so far the results is too hard for me ... but it's ok, thanks for the remind anyway, I will keep finding it.

sorry for the "big error".

Ah yes, both interface methods use raw pointers, which doesn't help in automatic type conversions. write core::stringw(node->getName()).c_str()

it works! Thanks a lot.
