Hi Ats,

The MeshImport component uses TZInputStream and its CreateFromMemory constructor specifically, so no Platform_ReadFile ( nor ReadAssetFile ) is involved.

Hi guys, I'm no Pascal / Delphi expert .. but why not use (regular) pointer arithmetic instead of converting back & forth between a integer and pointer? And the "does not seem to be initialized" warnings are the compiler being dumb ( afaik ): - In case of "ScaledGravity" it's...

Hi guys, Android 15 switched to Vulkan and includes ANGLE for backwards compatibility with OpenGL ES. Although they tout this change by stating "improved compatibility, and in some cases, improved performance", this might not always be the case .. especially during this transition period: ...

Hi Ats, On Linux ZGE only maps the arrow and letter keys to specific regions ( but nothing else ), you can view the source-code for that here . This is also working on Linux, that makes no sense to me It's because the KeyMap on Linux first gets initialized one-to-one .. but then the letter keys get ...

Hi Ats, Did something change? No idea .. but ZGE uses SDL on Linux. You can find the SDL keycodes here . Keep in mind that ZGE masks keycodes to a 9-bit range. So for example F2 / 0x4000003B becomes 59. I'm not sure if this is coming from linux or from ZGE, but the keycode for Linux are correct on h...

Hi Ats,

The 0x80E1 value equals GL_BGRA .. not GL_RGBA But yes, simply use GL_BGR as format in glReadPixels if you don't want / need the alpha channel.

Hi Ats, But now I am wondering how to scroll it... Like a scrolling texture. Is there a known technique for that? Not entirely sure what type of scrolling effect you're trying to achieve .. but perhaps it's either one of the following: <?xml version="1.0" encoding="iso-8859-1" ?>...

Hi Ats, Coming back to your original question(s) .. Currently, when the camera is inside an object, the interior polygons aren’t rendered, or they appear solid if I enable Material DrawBackFace. I’d like to render them semi-transparent. How can I achieve that? You can render the inside of a object u...

Hi Ats, There's a bunch of different ways to tackle this kind of situation. The easiest approach is probably the "Super Mario Sunshine" method .. where you basically render a "shadow" version of your character ( depth-testing disabled ) after rendering your environment, but befor...

Hi Ats, What is the difference between procedure TGLDriverFixed.RenderMesh(Mesh: TMesh); and procedure TGLDriverProgrammable.RenderMesh(Mesh: TMesh); ? One is for the fixed-function pipeline ( legacy OpenGL ), the other is for use with shaders ( modern OpenGL ). The fixed-function pipeline had funct...

Hi Ats, After some digging & PM'ing with Ville .. the "inverted" problem is probably caused by glGetIntegerv not being implemented fully ( GL_DEPTH_TEST and GL_CULL_FACE are missing ) in the ES1.x emulation layer used by modern Android devices. So if you're developing a project that ta...

Hi Ats,

Hmm .. i suspect this might be caused by GLESPixelsFromTexture executing at the wrong time. That function temporarily disables depth testing and face culling when using ES 1.0.

Good to see that the culprit was finally found!

8) The OBJ importer used to be extremely bare-bones .. or maybe you could even say broken. Didn't matter what vertex data your OBJ contained, the imported mesh would always have vertex colors enabled ( even though it didn't actually import any vertex color data ) and texCoords disabled. Normals were...

Oops, My mistake .. should have used round() to prevent the possibility of rounding errors. Try this instead :wink: <?xml version="1.0" encoding="iso-8859-1" ?> <ZApplication Name="App" Caption="ZGameEditor application" FileVersion="2" AndroidPackage...
