OpenGL Controls [Open Source]

Blake · **Posted:** Mon Feb 23, 2009 1:26 am

Hey guys, I just finished up working on some OpenGL Control Classes to use with rb and am opening them up to the public. I really want these to be customizable for use in any game so feel free to download, use, alter and offer up suggestions to improve them

The OpenGL Code is cross-platform so Mac & Windows programmers are welcome. One note for Mac users, there has been a couple cases of the thread running too quickly and locking up the app, if this happens just change the thread to a timer and remove the do & loop.

Wow... Today is my lucky day! I'm returning to RB to do some cross-platform applications that rely on OGL for the rendering context. I'll sure give your library a go. Thank you!

You're welcome

That is my main goal, to give everyone access to the tools needed to create quality games in rb.

Thanks !

I tried to compile it with RB 2008 5.1 (Mac) , didnt changed any code
but always get an compiler error

Control Builder.rb : OpenGLSlider1 on Console impements the Event "ValueChanged"
but his superclass Canvas has that event already implemented.

Hmm...Is there a value changed event for the canvas now? I'm using 5.5.5 so I am sure some things have changed.

If there is just comment out the even in the OpenGLControl class and it should work.

No, the error message is misleading.

When opening the project in some recent versions, the controls lose their super - it reverts to Canvas.

We can all have lots of fun resetting them to OpenGLControl

Thanks for help with that RB bug .
Q: How many times must i change canvas to OpenGLControl ?
All canvas in the projekt to OpenGLControl ?

Oh I didn't realize that they lost their super. Luckly I named them what they are so setting the super should be easy without guessing what sub-class it is

Just had a quick play with this - I really like it

Please excuse my lack of knowledge, I've been away from RB for about 5 years... But how is this installed? I've placed the whole Control Builder folder into the plugins directory but I don't think that's correct. Thx for bearing with me. :oops:

Its not a plugin, its straight RB code. Just launch the source (.rb) and set the supers of the canvases (if they are incorrect) and you are good to go.

Thanks Blake... Looks like I need to spend a bit more time in the User manual... :wink:

No problem, try the new download (first post) if you are having any more issues getting it working.

I've downloaded it, opened the project, and tried it in the debugger.
Each time it crashed when opening.

So I created a new Window, set its super property to OpenGLDisplay.
Then I added a control
And when debugging this new window it doesn't work either.

I am using RB 2008r4.2 on Windows Vista 32 bits

Sounds like it may be in the creation of opengl, can you step through the open event and see where its crashing?
