Game Development

@AI_Messiah There isn't any simple/supported way to do that. The intended workflow from Blender is to bake your textures to images, and export as something other than .blend for import into other applications. If you want to use Blender procedural textures in your own renderer, you'll either need to use a ton of Blender code in your app, or study their behavior and try to reimplement them from scratch.

I thought that this image only failed on your system. Does it have any other properties beside the size that makes it different from your other images ? Would it be possible for you to create a minimal compilable example using it ?

In Qt 5, QML is implemented using OpenGL. Can't get more "compatible" than that ;-) Check out QQuickItem documentation for more info. In Qt 6 it is different, because implementation is independent of the 3D API (it uses OpenGL, DirectX, Metal etc. depending on platform). For offscreen rendering, run your app with offscreen platform plugin: yourApp.exe -platform=offscreen

Another thing is how would I use physics like gravity, center of mass and collision detection and other stuff

Hi, As the class documentation states, the QPaintedTextureImage must be attached to a texture. The paint method provides you the QPainter instance you have to use.

You do not need special Qt OpenGL tutorials. Just use a few simple Qt OpenGL examples from Qt Examples https://doc.qt.io/qt-5/examples-widgets-opengl.html and use general OpenGL tutorials like: https://learnopengl.com http://opengl-tutorial.org http://ogldev.org https://open.gl https://thebookofshaders.com My simple examples in Qt OpenGL: Triangle: https://rextester.com/ZTRI45421 Texture: https://rextester.com/BJW63108 3D cube: https://rextester.com/IPI73465 Snake 2D: https://rextester.com/MMC15477 (I translated this example to Qt OpenGL 3.3 from the Python OpenGL 1.1 tutorial: https://noobtuts.com/python/snake-game)

What's the point of c here?

@AI_Messiah said in Can someone help me with this OpenGL code: I get these errors when I try to run it. These are link errors, you don't even get to the point of running anything. Firstly do switch to QOpenGLWidget instead of the deprecated class you use.

I built Qt to static release and compressed EXE using UPX. My EXE has only 7 MBytes. But I use pure OpenGL without Qt3D. [image: 11f5b800-9f03-4290-b879-d8ff5d9f1765.png] Cube_OpenGLES20_Qt5Cpp.zip [image: e9d00bd8-a9e0-4354-8cba-32b4be6583cc.png]

Hi, Before searching too far, you should add all the error checks that are missing to ensure that what you load and and build passes correctly (shaders, etc.)

Thanks thats what I needed

You can use your own ratio (for example 1:50) but Box2D has these limits: Box2D has been tuned to work well with moving shapes between 0.1 and 10 meters. So this means objects between soup cans and buses in size should work well. Static shapes may be up to 50 meters long without trouble. I got it from documentation. 1:30 means that your objects must be from 3 pixels to 300 pixels. If you use 1:50 - your objects must be from 5 pixels to 500 pixels.

You're most likely looking for QAbstractOpenGLFunctions.

You can use OpenGL in Qt. Qt supports all what you need, for example, you do not need GLM for matrices, you need to use QMatrix4x4. This method allow to set a camera position: https://doc.qt.io/qt-5/qmatrix4x4.html#lookAt I will send you my short examples for beginning in OpenGL: Triangle: https://rextester.com/ZTRI45421 Texture: https://rextester.com/BJW63108 Picking Triangle by Mouse: https://rextester.com/BBX4107 Cube in 3D: https://rextester.com/IPI73465 You can find a lot of very good tutorials about OpenGL and use them in Qt, for example: https://learnopengl.com http://opengl-tutorial.org http://ogldev.org https://open.gl https://thebookofshaders.com

Thank You!
