Tutorial 7 uses triangle versus sphere which might be too slow for 50 planes

is there a way of doing sphere-sphere?

and how do you detect colliisons in code?(e.g. bullet vs plane)

thanks

First of all thanks for your wonderful wrapper. I'm thinking of purchasing blitzmax (I already own blitz3d) to take the next step in its development but the lack of a 3d engine is making me hesitate, but all the info I found about your integration with Irrlicht is quite motivating and encouraging since I'm already an Irrlicht user, So I'm downloading blitzmax's demo and will try v1.30 of your wrapper for Irrlicht 1.5. Installation seems painless, however I'd love to see the samples ported to bmx language in action but the only ones available are for irrlicht 1.3.
Is there an updated package with sample files for Irrlicht 1.5?

Kind regards,

Alvaro F. Celis

I finally found a way to resize the GUI instantly inside the canvas !
It's incredible, but it really works !

Here's how to do, gman didn't included the IDriver.OnResize(size) function, that one was needed to resize the 3d view without having to restart...

Open C:\Program Files\blitzmax\mod\irrlicht.mod\core.mod\video\ivideodriver_wrap.h

After :

    IImage* IrrVideo_IVideoDriver_createImageFromStream(IVideoDriver* driver,IReadFile* file)
    {
        if (driver)
            return driver->createImageFromFile(file);
        else
            return 0;
    }

Add the following :

    void IrrVideo_IVideoDriver_OnResize(IVideoDriver* driver, s32 width, s32 height)
    {
        if (driver) {
            dimension2d<s32> size(width, height);
            driver->OnResize(size);
        }
    }

Save And Close.

Open C:\Program Files\blitzmax\mod\irrlicht.mod\core.mod\video\ivideodriver_wrap.bmx

After :

Function IrrVideo_IVideoDriver_createImageFromFile:Int(pIVideoDriver:Int, filename$z) ' returns IImage*

Add the following :

Function IrrVideo_IVideoDriver_OnResize(pIVideoDriver:Int, width:Int, height:Int)

Save And Close

Open C:\Program Files\blitzmax\mod\irrlicht.mod\core.mod\video\ivideodriver.bmx

After :

    Method createImageFromFile:IImage(filename:String)
        Return IImage.createFromHandle(IrrVideo_IVideoDriver_createImageFromFile(handle,filename))
    EndMethod

Add the following :

    Method OnResize(width:Int, height:Int)
        IrrVideo_IVideoDriver_OnResize(handle, width, height) ' returns IImage*
    End Method

Compile the modules.
Here's the full code to test :

' this is an example showing how to display Irrlicht in a panel on a MaxGUI form.  i have modified it a bit
' by adding an eventreceiver to the Irrlicht instance to show how MaxGUI and Irrlicht events can coexist.
' it is important to note that there still is probably some issues to work out, but for now this works.

Now, launch the program and resize... WOOT WOOT ! IT WORKS !

That's it guys, ENJOY !

Where do I get the documentation for this engine? Where can I ask questions by the bucketload?

I just am confused about where to start, and how. Thank you.

Just a quick question: in the irrlicht docs do you know where to find all the 2d commands? I cant seem to find them anywhere.e.g. draw2dimagesegment

Im seeing a post referencing version 0.14 but I cant find the download anywhere.
Im currently running blitzmax 1.28 and the irr 0.13 wrapper version.

Am i upto date with this install?

If not, where can i find the 0.14 distribution and the updated exmaples.

Thanks for any help here. I love irr and want to get started with it right away.

Whats the difference between irrlicht.b3d irrlicht.core gg.irrbmax and gg.irrlicht Im a bit confused here.

Also, where can i find the ib3d_ command examples? I found them somewhere before (basically the irrlicht examples converted) but cant seem to find them again anywhere. I notice you posted that the latest ib3d mod is released but i cant find it :?
