The new version cannot display text

I just downloaded the new version， but the new version cannot display text（All examples）

Works fine for me, just tested on both Linux and Windows.

The error looks like missing freetype DLL (it looks like you’re on Windows).

How do you compile? If you use “Compile and Run” from CGE editor, or CGE command-line build tool, then we will copy the DLL files into the project automatically. (We do this regardless of which compiler, FPC or Delphi, is used.)

But if you compile and run from Lazarus IDE / Delphi IDE, you have to copy DLLs into the project (alongside EXE) yourself, we have no “hook” to do it reliably then automatically. See Compiling from source | Manual | Castle Game Engine for links to Windows DLLs.

The simplest advise is to just compile at least once from CGE editor to get DLLs. Let CGE automatically put proper DLLs into the project.
What does the log show? (You can see log e.g. in CGE editor; if running outside of editor, see Logging | Manual | Castle Game Engine ).

Use CGE editor compile and run， exist freetype.dll file

Hm, looks like we detected your GPU as “not being able to use modern shader pipeline”.

But I also just tested – even if I force CGE to use “ancient fixed-function pipeline” for me, it can still render letters in platformed OK. So, I am still perplexed what is the issue

Indeed the log confirms we load TTF font OK, so FreeType DLL is used OK:

Font: Creating image 512x512 to store glyphs of font “castle-data:/font/kenvector_future_thin.ttf” (95 glyphs, max glyph size (including 2 pixel padding) is 34x39)

So I suspect we have a rendering bug specific to your GPU, but don’t know yet why.

Please add LogGLInformationVerbose := true to the code/gameinitialize.pas source file in “platformer” project. Add attach the log here (it will be much longer).
Does other font rendering work OK for you? Please run examples/component_gallery. Do you see letters OK there? Do you see letters OK in “Label” page of that demo (it uses some fonts from TTF, some embedded in CGE)? Proper screenshots from this example are on User Interface | Manual | Castle Game Engine .

error message

Both of my computers are like this，The default system language for Win10 is not English，Is it related to this?

soastao · April 4, 2023, 7:26am

michalis · April 4, 2023, 1:13pm

The Windows system language should not be related. Especially since you show that also examples/component_gallery renders incorrectly all the labels. But in examples/component_gallery we use default font for the left sidebar (we have this default font embedded in Pascal, we don’t use FreeType for it).

The warnings about SoundFromName are also not related. We should update the platformer example to not use deprecated SoundFromName, but this is unrelated to rendering problems.

Can you submit the full log output, on both systems where it fails, after you set LogGLInformationVerbose := true in the code/gameinitialize.pas? (from any example really - platform, component_gallery, should not matter)

soastao · April 4, 2023, 1:42pm

add LogGLInformationVerbose := true

Thank you!

I see here 2 things I’d like to fix:

For this GPU, we detect “Necessary to use deprecated fixed-function pipeline: True” because we detect BuggyPureShaderPipeline for it.

But maybe we should try harder and not define BuggyPureShaderPipeline in this case, treat it more like a modern GPU – which it should be, as it has OpenGL 4.6.
Regardless of it, treating it like “Necessary to use deprecated fixed-function pipeline” should not cause rendering bugs.

Good news – I found an older laptop, with a GPU exhibiting similar problem (though it’s not AMD, it’s Intel). I should be able to use it to make letters rendering reliable, regardless of “Necessary to use deprecated fixed-function pipeline” .

I’ll let here know when it’s fixed.

michalis · April 11, 2023, 1:19am

AD 2 Fixed.

I pushed 2 fixes to GPUs we detect as “using fixed-function rendering” to GitHub - castle-engine/castle-engine: Cross-platform (desktop, mobile, console) 3D and 2D game engine supporting many asset formats (glTF, X3D, Spine...) and using modern Object Pascal . As usual, the fix is

available on CGE “master” branch on GitHub immediately
and after a few hours it will be available inside downloads on Download | Castle Game Engine too.

So font rendering will work fine for you.

AD 1 is still a TODO – ideally, I’d like to activate “modern rendering” for this GPU.

michalis · April 17, 2023, 2:01am

AD 1 also fixed!

There have been a few fixes for ATI GPUs lately. In particular the BuggyPureShaderPipeline property is now completely removed (it is never buggy now ), rendering on older ATI cards is now both more reliable and consistent with what happens on more modern GPUs (ATI or not ATI).

So - font rendering should be OK for you, and also you should see Necessary to use deprecated fixed-function pipeline equal to False in the log now.
