Lua Edu Tools beta version

[selden]

I just now downloaded and installed the most recent version of Lua Edu Tools.

On my system, numeric-pad-8 (pitch down; screen scrolls up) is not functioning, although 7 and 9 (roll) work, 4 and 6 (yaw) work, and 2 (pitch up) works, too.

Typing Ctrl-F does not and should not change the numeric pad keys, only the arrow keys. The arrow keys do correctly change state, and the up and down arrows properly pitch up and down.

[edit]
With the Edu Tools not loaded (luahook commented out), numeric-pad-8 works fine.

With the Edu Tools running, Shift-I makes no difference in the numeric pad: 8 continues to be disabled.

Strange.

System configuration:
2GB, 1.86GHz Core2Duo 6300; Win XP Pro SP2
128MB, Quadro 550; ForceWare v91.85
Celestia v1.5.0pre3 and from cvs.

Selden,

I get exactly the same behaviour with the numpad 8 key on my system.
I think more about a bug in the C++ Lua Hook code than in the Lua code itself.
I'm going to investigate this. Strange indeed...

Thanks.

[Vincent]

I think more about a bug in the C++ Lua Hook code than in the Lua code itself.

Actually, I was wrong. The bug concerned the key mapping Lua code.
I'm quite happy to have located it ! It should be fixed now.

Selden,
Could you please confirm that the bug is also gone on your system ?

Frank,
Could you please let me know if this fixed also the left/right arrows
and the 4/6 numpad keys bug ?

Only the 'lua_edu_tools.lua' was changed.

Thanks.

Vincent,

Unfortunately, when I downloaded the zip file just now from the link in your .sig, I got the old version: lua_edu_tools.lua is dated June 10.

I'll try again in a while.

[selden]

The updated version does fix the numeric keypad bug for me!

[fsgregs]

Vincent:

Yes, that fix seems to have fixed things.

Thanks

Does anyone know if the GL_POINTS command in available in the lua code for celestia?

Great !
Selden, Frank, Thanks !

Does anyone know if the GL_POINTS command in available in the lua code for celestia?

Jedi,

GL_POINTS is not part of the Celestia Lua OpenGL library yet.
Here are the commands that are the currently available (celx.cpp, line 5492):

RegisterMethod(l, "Frustum", gl_Frustum);
RegisterMethod(l, "Ortho", gl_Ortho);
RegisterMethod(l, "Color", gl_Color);
RegisterMethod(l, "TexCoord", gl_TexCoord);
RegisterMethod(l, "TexParameter", gl_TexParameter);
RegisterMethod(l, "Vertex", gl_Vertex);
RegisterMethod(l, "Translate", gl_Translate);
RegisterMethod(l, "BlendFunc", gl_BlendFunc);
RegisterMethod(l, "Begin", gl_Begin);
RegisterMethod(l, "End", gl_End);
RegisterMethod(l, "Enable", gl_Enable);
RegisterMethod(l, "Disable", gl_Disable);
RegisterMethod(l, "MatrixMode", gl_MatrixMode);
RegisterMethod(l, "PopMatrix", gl_PopMatrix);
RegisterMethod(l, "LoadIdentity", gl_LoadIdentity);
RegisterMethod(l, "PushMatrix", gl_PushMatrix);

RegisterValue(l, "QUADS", GL_QUADS);
RegisterValue(l, "LIGHTING", GL_LIGHTING);
RegisterValue(l, "LINE_LOOP", GL_LINE_LOOP);
RegisterValue(l, "POLYGON", GL_POLYGON);
RegisterValue(l, "PROJECTION", GL_PROJECTION);
RegisterValue(l, "MODELVIEW", GL_MODELVIEW);
RegisterValue(l, "BLEND", GL_BLEND);
RegisterValue(l, "TEXTURE_2D", GL_TEXTURE_2D);
RegisterValue(l, "TEXTURE_MAG_FILTER", GL_TEXTURE_MAG_FILTER);
RegisterValue(l, "TEXTURE_MIN_FILTER", GL_TEXTURE_MIN_FILTER);
RegisterValue(l, "LINEAR", GL_LINEAR);
RegisterValue(l, "NEAREST", GL_NEAREST);
RegisterValue(l, "SRC_ALPHA", GL_SRC_ALPHA);
RegisterValue(l, "ONE_MINUS_SRC_ALPHA", GL_ONE_MINUS_SRC_ALPHA);
lua_settable(l, LUA_GLOBALSINDEX);

lua_pushstring(l, "glu");
lua_newtable(l);
RegisterMethod(l, "LookAt", glu_LookAt);
RegisterMethod(l, "Ortho2D", glu_Ortho2D);

I'd like to add the gl_LineWidth command to allow line smoothing for Lua distance markers too. So, I could add GL_POINTS as well it if it appears to be useful. Just let me know...

[Vincent]

Jedi and I have optimized the distance markers. The "distances" check box now cycles through the following steps:
0- No distance marker is displayed.
1- Only square markers centered on screen are displayed in the observer's plane.
2- Only circle markers centered on the current selection are displayed in the ecliptic plane.
3- Both the square and the circle markers are displayed.

I've also finely tuned the size of the markers. The following screenshot shows how well the 1 AU circle marker matches the orbit of the Earth. Note also how both curves are crossing exactly when the Earth is at 1.0000 AU from the Sun:

I've also changed the behaviour of the timerate slider which now works like the new FoV slider.
One advantage of this version is that the "slow", "medium", "fast" buttons are not needed anymore.

Thanks, I was looking in the source code for that. I think that GL_POINTS would be very useful.

[ElChristou]

Vincent, those 3 options are quite cool!

[cwiz]

very cool.

Now I don't have to write my own version. That saves me loads of time and money. hehe.

[DT]

This is already possible by editing the config.lua file.
The last version of the Lua Tools is available here:
http://shatters.net/forum/viewtopic.php?t=10352

Is this the one you've tested ?

I just went through the config file, that's excellent. The version I am testing is the one that is attached to your signature, it looks to be the same link.

As I said before, I would like it to replace the Menu bar, it makes Celestia more immersive.

Excellent work.

[ANDREA]

Vincent, sorry for asking it once again, but do you have any (good) news about sound capability in Lua Edu Tools for Celestia 1.5?
Tks for your patience.
Bye

Vincent:

I too am most anxious for any word about sound. Since you built it into Celestia-ED 141, it has been a GREAT feature. I use it throughout all 12 educational activities. My students love it.

The overlay feature that is part of Celestia-ED 1.4.1 is also a vital part of the program. I know LUA tools incorporate lots of new overlay features, but the spacecraft cockpit overlays in Celestia-ED 1.4.1 are really wonderful. Hopefully, they would not be too difficult to incorporate into 1.5.0 also

Andrea, Frank,

Please see http://celestiaproject.net/forum/viewtopic.php?t=11429

Frank, the spacecraft cockpit overlays can already be displayed via the current Lua interface. I can help you to do that if you want.

Thanks ! I'll post an updated version very soon.

Are you saying that you'd like the Lua Tool bar to replace the standard Menu bar, or that you'd like the Lua Tool bar to be hidden to make Celestia more immersive ?

In the first case, you can switch to full screen mode with [Alt] + [Enter].
As for hidding the Tool bar, I've been thinking about it. So far, this could be done with a simple click. However, it would be nicer to bring the Lua Tool bar up when the mouse reaches the right hand side of the window, and to make it disappear automatically otherwise. That would require another Hook in the code, though.

[ElChristou]

...That would require another Hook in the code, though.

If possible, is there a problem to not add this hook?

Chris,

I think you know the problem as well as I do : the current development of Celestia is at a standstill, and there are priorities on which the dev team has to focus before discussing this kind of adds.

, yep... but actually as there is no dev at all... I was thinking adding a hook should not be so problematic...
