MAUI: Surf's Up!
by Inventor-66＠comcast.net 31 Mar '08

31 Mar '08

spencer, A thousand thank-you's oh mighty code warrior, as Klinger of M*A*S*H would say... I'm happy to hear that MAUI is on the way soon! I've written two applications in MAUI, Guitar Lab and Synth Lab, and probably 2/3 of my audience can't run the software right now. It will be a big relief when they can, plus the flurry of activity as our PC/Linux friends add MAUI to their programs should be fun. So thanks and good luck with your coding! Inventor

MAUI for PC/Linux
by Inventor-66＠comcast.net 31 Mar '08

31 Mar '08

It seems that there is a strong demand for the MAUI port to PC and Linux versions of the miniAudicle. In fact there's so much demand for a ChucK GUI that three or four people have created their own ChucK GUIs and posted about them to the forum. Being gifted with MAUI powers as a Mac user, it is unfortunate that I cannot share my MAUI programs with many fellow ChucKists. I wonder if we could get some news about the MAUI porting progress? Perhaps someone on the dev team can fill us in? Inventor

Hello list, I've upgraded my os x from tiger to leopard (reason: the latest apple combo update screwed my 10.4 system..:( ) and now, when running chuck, I get the following error: chuck[11494:10b] Error loading /Library/Audio/Plug-Ins/HAL/ DVCPROHDAudio.plugin/Contents/MacOS/DVCPROHDAudio: dlopen(/Library/ Audio/Plug-Ins/HAL/DVCPROHDAudio.plugin/Contents/MacOS/DVCPROHDAudio, 262): Symbol not found: __keymgr_get_per_thread_data Referenced from: /Library/Audio/Plug-Ins/HAL/DVCPROHDAudio.plugin/ Contents/MacOS/DVCPROHDAudio Expected in: /usr/lib/libSystem.B.dylib 2008-03-29 23:19:31.110 chuck[11494:10b] Cannot find function pointer NewPlugIn for factory C5A4CE5B-0BB8-11D8-9D75-0003939615B6 in CFBundle/ CFPlugIn 0xc115c0 </Library/Audio/Plug-Ins/HAL/DVCPROHDAudio.plugin> (bundle, not loaded) [test.ck]: syntax error yet, chuck seems to perform alright. Has anyone had the same? any solutions or ideas on what this error means and how is this affecting chuck? BTW, I'm running chuck-1.2.1.1. thanks, eduard

Hi I'm wondering what's the status of a new release of chuck/miniAudicle? Mostly I'm hoping for maui/widgets to work under linux, will this happen? -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk

midi out
by Atte André Jensen 29 Mar '08

29 Mar '08

Hi For the first time I need to use midi out. I couldn't find any examples, but thought it might be similar to midi in, so I did: MidiOut midi_out; MidiMsg midi_msg; midi_out.open(1); 0 => midi_msg.data1; 0 => midi_msg.data2; 0 => midi_msg.data3; midi_out.send(midi_msg); But that gives me the following error: [chuck](via RtMidi): RtMidiOut::sendMessage: event parsing error! Could anyone point me in the direction of a working midi out example? -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk

Re: [chuck-users] Moving MAUI Buttons and What's Up with MAUI Porting?
by Inventor-66＠comcast.net 26 Mar '08

26 Mar '08

Greetings fellow ChucKists, Inspired by Kassen's comments, I expanded that example that I posted of moving a button with the mouse. Now it is a complete little one-person Pong game. I posted it to the WiKi under Example Programs, and also to the forum. It's actually more like Breakout because the paddle is on the bottom of the window, not the side. Each time you hit the ball you score a point when it reaches the top and each time you miss the ball ChucK scores a point when the ball travels off the bottom of the screen. Naturally, I added some sound effects to make it complete. There is some ghosting if you move the mouse too quickly but otherwise it works like a charm. What is next, ChucK Quake? Les (Inventor)

Moving MAUI Buttons and What's Up with MAUI Porting?
by Inventor-66＠comcast.net 25 Mar '08

25 Mar '08

Hi ChucK friends, I made a ChucK file with MAUI that demonstrates moving a button on the view panel with the mouse. The source code follows: // experiment with mouse moving a button in MAUI // copyright 2008 Les Hall // This software is protected by the GNU General Public License // set up the view panel 400 => int x_max; 400 => int y_max; 1280 => int screen_width; 960 => int screen_height; MAUI_View mouse_view; mouse_view.size (x_max, y_max); mouse_view.position (screen_width/2 - x_max/2, screen_height/2 - y_max/2); mouse_view.name ("Click and drag the square button!"); mouse_view.display (); // create the button 200 => int x_pos; 200 => int y_pos; 60 => int button_size; MAUI_Button mouse_button; mouse_button.toggleType (); mouse_button.size (button_size, button_size); mouse_button.position (x_pos - button_size/2, y_pos - button_size/2); mouse_button.name (""); mouse_view.addElement (mouse_button); // create a dummy button MAUI_Button mouse_button2; mouse_button2.toggleType (); mouse_button2.size (x_max, button_size); mouse_button2.position (0, 0); mouse_button2.name ("Experiment with moving buttons"); mouse_view.addElement (mouse_button2); 0 => int device; Hid hid; HidMsg hidmsg; if (!hid.openMouse (device)) me.exit(); 0 =>int move_mouse; // infinite time loop while (true) { // wait on event hid => now; // loop over messages while (hid.recv (hidmsg)) { if (hidmsg.isButtonDown()) { 1 => move_mouse; } if (hidmsg.isButtonUp ()) { 0 => move_mouse; } if( hidmsg.isMouseMotion() ) { if (move_mouse) { // add the mouse movement to x and y positions hidmsg.deltaX +=> x_pos; hidmsg.deltaY +=> y_pos; // check lower limit on x if (x_pos < 0) { 0 => x_pos; } // check upper limit on x if (x_pos > x_max - button_size) { x_max - button_size => x_pos; } // check lower limit on y if (y_pos < button_size) { button_size => y_pos; } // check upper limit on y if (y_pos > y_max - button_size) { y_max - button_size => y_pos; } // move the button mouse_button.position (x_pos, y_pos); mouse_view.addElement (mouse_button); // delay to let system catch up 0.1::ms => now; } } } } I hope that's not too much source code to put in a post. Is this something intended, or a happy coincidence? Just thought I'd share. Pong anyone? Oh, and by the way, what's up with porting MAUI? I've been writing great fun stuff in MAUI including Guitar Lab and Synth Lab, and I'd like to share these programs with my friends who can't run MAUI. Thanks, Les
