When no depth buffer is bound D3D depth state should be enabled, so drawing can happen without the need for a depth stencil state to be set.

Hey! I get the following error when I try to build the examples on Mac OS 10.15.2

ios and osx can share audio, timer and other platform implementations of certain features.. needs premake support to configure which folders to add

No support pthread_cancel at android platform.

The file examples/code/debug_primitves/debug_primitives.cpp is empty.

Releasing frame buffer was causing a crash and is currently commented out, check other D3D resource releasing is ok too.

Hi,

I tried the example of 'blend_modes'. it worked well.

however, when I tried the hot reloading, it crashed with the following:

1. open blend_modes.jsn and add technique : debug in view_no_blend, the reload was triggered but with a crash.

Hi, thought I should bring up that the copyright is listed as 2014 - 2019 in all of the files I've opened so far.

Issue is with sampling texture arrays inside a loop with a dynamic index... there is an issue raised in pmfx-shader with more info

I want to fix this because it is useful to have an OpenGL implementation on macOS, but for now Metal is the preferred API to use.

Hello, I wanted to try out the engine, I followed build instructions, everything went fine.

But when I run any example in examples/bin/linux folder, i get error while loading shared libraries: libfmod.so.11: cannot open shared object file: No such file or directory.

Looking into the directory, it seems there is a libfmod.so and a libfmodL.so but no libfmod.so.11 unfortunately.

Do you know how to fix this ? (tried renaming libfmod.so to libfmod.so.11 but didn't work)

Hello, I had some fun and problems on Windows I'd like to share, maybe it is of some use.

If build.py is called without args then the variabile _info is not initialized.
Solved by calling _info = build_info() in get_platform_info.

In build.py, for Windows it could be helpful to set 'python_exec' to 'py -3' in case you have both pythons.

In someway or another I had an empty info.json file in examples\bin\win32\data\pmfx\hlsl\compute, this caused the json parser to crash.
Solved by adding a check on the file size in check_dependencies of build_pmfx.py:
if os.path.exists(info_filename) and os.path.getsize(info_filename) > 0:

The compute shader was a bit tricky: calling build without args will default to HLSL 4.0, this causes the shader greyscale to be skipped since it has "supported_platforms 5.0". Here a warning for the skipped shader could be useful, otherwise all seems good but the compute example will crash because there is no technique in the shader.
By setting -shader_version to 5_0 I was able to compile it, the sample was running but I had a black screen with the error "d3d device error: The parameter is incorrect." and:

I get that only DXGI_FORMAT_R8G8B8A8_UNORM is supported. Changing it in dds_pixel_format_to_texture_format solved this.

Hi,

First of all thank you for this awesome library. The code structure is very clean.

I'm still exploring pmtech and trying to build for wasm but got linker errors when pmbuild is building audio_player. I was following the steps in the Building page in the wiki. I'm using the latest emscripten sdk-releases-upstream-89202930a98fe7f9ed59b574469a9471b0bda7dd-64bit on macOS Big Sur. Same error happens on Linux KDE Neon (based on ubuntu 20.04):

Linking audio_player
error: undefined symbol: _ZN3put18audio_channel_stopEj (referenced by top-level compiled C/C++ code)
warning: Link with `-s LLD_REPORT_UNDEFINED` to get more information on undefined symbols
warning: To disable errors for undefined symbols use `-s ERROR_ON_UNDEFINED_SYMBOLS=0`
warning: __ZN3put18audio_channel_stopEj may need to be added to EXPORTED_FUNCTIONS if it arrives from a system library

and many more similar errors.

Just want to say thanks for this lib! I've been searching for something like this (fast, minimal but complete) for a long time.

Feel free to close this non-issue any time :)

Now I am working with some massive huge model, it will draw too many objects. So I hope this can implement some gpu culling like this in bgfx:

It seems pmbuild should be able to find VS2019 if installed.
I do not have it on C:, so that may be the issue.
After manually specifying the path to the vcvarsall.bat I get an error.

are there any docs? and if not are there any plans to make them?

Vulkan version cannot compile successfully. This is the error.

pmtech\source\pen\source\vulkan\renderer_vulkan.cpp(2183): error C3861: “renderer_tcp_resolve_ratio”

the 1st param of renderer_dispatch_compute should be number of groups, right?

convert hlsl to glsl

Hi, I looked over at the trello wip and was wondering what are the current plans regarding completing the Vulkan backend.
Thank you
