Game Development

Hej A.K.G. I'm only found in the documentation that is possible with extensions. My idea to solve your problem is: Integrate a physic engine like Bullet (http://bulletphysics.org/wordpress/) and you find out all collision detection and physics. Qt 3D as 3D drawing engine, and Bullet (or other software) for physic & collision representation. Regards, Jakob

Hi, That's a question better asked on the interest mailing list. You'll find there Qt3D's developers/maintainers. This forum is more user oriented.

Take a look at the Graphics View examples. Several of your questions are already answered there.

Hi, AFAIK, no. You’d likely have to go through calculating the size of the needed rectangle using QFontMetrics. If your text is so long and you need to know what wasn’t shown, why not use a QTextEdit ? It could be read-only.

I'm having the same problem with the simple gamepad example. What fixed the problem for you? Thanks

@Caipiblack I don't see a signal deviceRemoved() in QtGamePad. The nearest one is connectedChanged(bool) but that looks indeed like a possible signal in this situation. Have you already tried to patch the code yourself? Due to the lack of a gamepad, I cannot test this myself. Regards Edit: Ah, there is a deviceRemoved() signal in QEvdevGamepadBackend which is used within the backend only for housekeeping. What stays, the signal you need outside is connectChanged(bool).

@Nonlinearsound After reading through the release statements and changes it seems that the AC3D format has been supported right from the start of the AssImp project so it seems that any version will do fine.

@raven-worx Works! Thanks!

Probably is just something that is messed up with with your multiplcation or division on the aspect ratio. I'm just too lazy right now to think about it properly, so I just goint to copy paste one example of my that I know it works, so can try to adapt your code. if (width() <= height()) projection.ortho(-(Range),Range,-Range*h/w,Range*h/w,-(Range*2),Range*2); else projection.ortho(-(Range*w/h),Range*w/h,-Range,Range,-(Range*2),Range*2);

Qt 5.11 adds a general purpose raycasting feature http://doc-snapshots.qt.io/qt5-5.11/qt3drender-qraycaster.html It's not particularly well documented yet. Details like that are still in the process of being cleaned up as Qt3D matures.

Figured it out. Make pop up request for write permission if it doesn't have it in Qt 5.10: # .pro file android { QT += androidextras } #include <QtAndroidExtras/QtAndroid> ... QtAndroid::requestPermissionsSync( QStringList() << "android.permission.WRITE_EXTERNAL_STORAGE" );

Ok, thanks for the tip.

Thanks for the feedback !

I'm not sure why your example didn't work, because your graph looks exactly like mine. Anyway, in case someone is interested in a working example (like I desperately was), here's one on GitHub.

Hi, You should add which version of Qt you are using as well as the Android version and hardware.
