Ogre graphical console

[PixL]

One thing that ogre lacks is a functioning console. A console should be one of the essentials of any game. So today I've desided to put together a simple console class that supports just the basics like scrolling, command prompt and command callbacks. It is allso animated like quake console Here is a screenshot:



Here is the code:

using namespace std;

class OgreConsole:public Singleton<OgreConsole>,FrameListener,LogListener,KeyListener{
public:
	OgreConsole();
	~OgreConsole();

	void	init(Ogre::Root *root);

	void	setVisible(bool visible);

	void	print(const String &text);

	virtual bool frameStarted(const Ogre::FrameEvent &evt);
	virtual bool frameEnded(const Ogre::FrameEvent &evt);

	void keyClicked(KeyEvent* e);
	void keyPressed(KeyEvent* e) {}
	void keyReleased(KeyEvent* e) {}

	void addCommand(const String &command, void (*)(vector<String>&));
	void removeCommand(const String &command);

	//log
	virtual void write( const String& name,
					const String& message, 
					LogMessageLevel lml = LML_NORMAL, 
					bool maskDebug = false ){print(name+": "+message);}

Hope this was useful to someone

btw, how do I put it on wiki? I'm totaly clueless on how to use the wiki I can't find any link for uploading/creating a new page.

[Praetor]

Cool. This is definitely useful. I suggest you run over to the wiki and create an article for this so it doesn't get lost in the forums.

[Wretched_Wyx]

I agree with Praetor, get that on the Wiki! Very useful, and very cool.

btw, how do I put it on wiki? I'm totally clueless on how to use the wiki. I can't find any link for uploading/creating a new page.

Help/FAQ Page

The way I always start a new page, is by searching for the title of the page. So long as that exact page doesn't exist, at the top of the search page you would see "No page with this exact title exists, trying full text search". The "exact title exists" would be a red link. If you click on this, it will create a page with the title you searched for.

Another method would be to edit an existing page, making a link to your yet-to-exist page. For example, this console code would fit nicely in the Code Snippets section, under System (?). So if you went to that page, and scrolled to system, there would be an [edit] link. Click that link to edit that particular section. Then you can simply copy an existing link, replacing the name "[[YourPageName|" and description "YourDescription]]". Save the edit, click on your newly added link, and edit your page!

I hope that helped, if not then let us know and we'll go from there.

Login to the wiki using your forum credentials, go to an unused page you want to fill out (eg. http://www.ogre3d.org/wiki/index.php/Console ) and it will say "There is currently no text in this page". So just hit the Edit tab and add some.

The wiki doesn't have an "add a page" link. You just go to where you want content, and add it.

[Edit] Wretched_Wyx beat me.

[haffax]

Definitly useful and definitly wiki-material.
But actually "Ogre isn't lacking" a console, Ogre just doesn't have one, because it is outside its scope. This is very application specific.

To create a new wiki-page, simply enter the page name in the search box. It will tell you that the search failed and give you a link("this exact title"), where you can create the page. Be sure to link your page somewhere, for instance in the code snippet section.
Also, you might want to add the page to the Code Snippet category.
To do this, add

Code: Select all

[[Category:Code Snippet]]

to the bottom of the page.

[Wretched_Wyx]

Wretched_Wyx beat me...

Tehe... I thought for sure by the time I hit submit, somebody else would have beaten me to the punch. Off topic, but I miss Firefly...

OK thanks. Got it up on wiki now

'This is a great snippet, thx.

But I got a problem with the LogManager:

LogManager::getSingleton().addListener(this);

gives this error:

console.cpp(50) : error C2039: 'addListener' : is not a member of 'Ogre::LogManager'

I know in 1.4 something has changed with the Log system, but I couldnt really figure out how to make this work in 1.4
(LogListener are no longer added to the LogManager. Instead, addListener and removeListener have been added to Ogre::Log. So, you will need to get the log you wish to add a listener to, messages will no longer be broadcast for all created logs to listeners. Also, the interface is slightly different then previously, please check Ogre::LogListener (in OgreLog.h) class for details - eh?)

Any ideas? Thx

[KungFooMasta]

This would be pretty useful!

Do you mind if I use your code as a reference to build a console widget for QuickGUI?

KungFooMasta

[SpaceDude]

Any ideas? Thx

How bout something like this:

Code: Select all

Ogre::LogManager::getSingleton().getDefaultLog().addListener(this)

Or you could create your own log and listen to it like this:

Code: Select all

Ogre::LogManager::getSingleton().getLog("Console").addListener(this)

That's strange, LogManager seems to be missing a function to get a list of all the logs... But in theory you could loop through all the logs and add yourself as a listen to each of them. The list of logs is found here:

Ogre::LogManager::mLogs

ogreconsole is not compatible with ogre 1.4 ?

when i compile it i have a error : 'OgreEventListeners.h' : No such file or directory

Eihort removed all intput/event related stuff. You will need to port those pieces to whatever input system you use; the demos use OIS.

[nickgravelyn]

This is real cool. I have a couple bugs/suggestions:

The first bug I've found is that when I pump OIS events into the system, it writes blank space for shift, control, the arrows, etc.

The second is that occassionally the background disappears from the console.

As far as suggestions, I'd suggest remaking the files using OIS for ease of integration for people. I'd also suggest allowing native use of the up/down arrow keys to scroll through previous commands. That'd be real cool.

Good work.

[rluck]

Any chance someone could post this w/ OIS? I'm having a hell of a time compiling it and getting all forms of errors with such a simple change.

edit: nvm, done. Heres the code for anyone that comes here looking for the same thing.

Used this code and modified it to add buffered commands. Very usefull for a game (thanks to its author)

but I had some problems :
Shouldn't the lines

Code: Select all

else
   {
      char legalchars[]="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890+!\"#%&/()=?[]\\*-_.:,; ";
      for(int c=0;c<sizeof(legalchars);c++){
         if(legalchars[c]==arg.text){
            prompt+=arg.text;
            break;
         }
      }
   } 

be

Code: Select all

else
   {
      char legalchars[]="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890+!\"#%&/()=?[]\\*-_.:,; ";
      for(int c=0;c<sizeof(legalchars)-1;c++){
         if(legalchars[c]==arg.text){
            prompt+=arg.text;
            break;
         }
      }
   } 

to prevent '\0' to match with arg.text ???

[_tommo_]

Wow really useful... i was looking for a thing like this from much time

Straight inserted in our engine thanks so much!

[birmacher]

Hy,

How would I able to build up the function I want to register to the console?
It's ok that I should use the addCommand func:), but how should the function look like.

I have this:

Code: Select all

namespace game {
class Class1 {
public:
(...)
void exit ( );
};
};

after that when I say that OgreConsole::getSingleton().addCommand("quit",&game::Class1::exit);
i get this error:
'engine::OgreConsole::addCommand' : cannot convert parameter 2 from 'void (__thiscall game::Class1::* )(void)' to 'void (__cdecl *)(std::vector<_Ty> &)'

[SpaceDude]

Try this:

Code: Select all

namespace game {
class Class1 {
public:
(...)
void exit (vector<String>& Params);
};
};

[birmacher]

Thx, it works correctly if the function is not included in a class.
So addCommand ( "quit", &exit_cmd )

but inside a class it gave the next error after
So addCommand ( "quit", &game::Game::exit_cmd )
cannot convert parameter 2 from 'void (__thiscall game::Class1::* )(std::vector<_Ty> &)' to 'void (__cdecl *)(std::vector<_Ty> &)

[SpaceDude]

Function pointers is actually one of the most difficult concepts to grasp in C++ programming, they aren't used very frequently. But if you are interested you can read about them here:

http://www.newty.de/fpt/index.html

The problem with your code is that when you just specify "game::Class1::exit_cmd" as the function to call, it doesn't know which instance of the class "Class1" to use. In this case your "Class1" class is probably a singleton but the compiler doesn't know that. The easiest way to solve it is by making your function static like so:

Code: Select all

namespace game {
class Class1 {
public:
(...)
static void exit (vector<String>& Params);
};
};

But then you won't be able to access non-static variables and functions from within exit (essentially making it act as if it was a global function in the namespace game::Class1).

[oeginc]

Surprisingly I was able to get this code into my project and get it somewhat working....

The problem I am having now is... How do I feed the input to the onKeyPressed method?

Right now I have in my FrameListener something like this...

Code: Select all

mKeyboard->capture();
// Exit if we press Esc
if (mKeyboard->isKeyDown(OIS::KC_ESCAPE))
{
	return false;
}

[Jabberwocky]

You'll want to implement an OIS::KeyListener class in your code, so you can catch the key events, then have some code like this:

Code: Select all

bool MyInputClass::keyPressed( const OIS::KeyEvent& i_event )
{
   OgreConsole::getSingleton().keyPressed( i_event );
}

(I'm just kinda winging that code, but it'll look something like that).

If you need help with the OIS specifics, you can post on the OIS forums

[DEvil HUnter]

bug:
unhandeled exeption thrown if you press return and input string is empty or only spaces...

this solve it:
change this (in onKeyPress(...)):

Code: Select all

...
//try to execute the command
for(map<String,void(*)(vector<String>&)>::iterator i=commands.begin();i!=commands.end();i++){
...

to this:

Code: Select all

...
//try to execute the command
if(params.size())
   for(map<String,void(*)(vector<String>&)>::iterator i=commands.begin();i!=commands.end();i++){
...

things making the code better:

            prompt+=arg.text;
            break;
         }
      }
   } 

be

Code: Select all

else
   {
      char legalchars[]="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890+!"#%&/()=?[]\\*-_.:,; ";
      for(int c=0;c<sizeof(legalchars)-1;c++){
         if(legalchars[c]==arg.text){
            prompt+=arg.text;
            break;
         }
      }
   } 

to prevent '\0' to match with arg.text ???

yes is better! '\0' should never be in the entered string...


this code change make the insert of blank lines possible (pressing return)
in print(...):

Code: Select all

...
if(line.length())
      lines.push_back(line);
...

changed to:

Code: Select all

...
lines.push_back(line);
...

Hey i just hoped someone could tell me the correct code to pass input into the console and what function to put it in. I cant seem to find this anywhere i think this should be included in the wiki just as an example

i was trying something like this but i think this is passing in a blank key every time
OIS::KeyEvent e(mKeyboard, OIS::KC_UNASSIGNED,0);
OgreConsole::getSingleton().onKeyPressed(e);

i was calling the code in
virtual bool processUnbufferedKeyInput(const FrameEvent& evt)
in exampleframelistener.h

thankyou for any help
