DAABBCC - Dynamic Tree(aka AABB Tree) native extension for fast AABB collision detection

Yes I have had this issue, however this platform example now works out the box
(I am on Ubuntu, old Nvidia card). A thing I had to do was change ‘Opengl version hint’ from ‘highest available’ to a set value (eg 3.3 and 4.6 works); (and I do this to make defold-pixelart-shader-example work). I don’t know why, I just keep throwing stuff at the wall until something sticks:-)

Ah! Yes, this is also worth trying. Did you try Vulkan on Linux? (just curious)
I’d like to clarify that these issues are not specific to those projects.

Vulcan results in:

INFO:GRAPHICS: Vulkan device selected: NVIDIA GeForce GTX 1080
ERROR:ENGINE: Could not find '@render' socket.

And gives me a black window.
Edit:
Tested with ‘Linker sample game’
‘Opengl version hint’ = ‘highest available’ Does not work. (3.3 does work)
Vulcan ‘works’ and prints the error (ERROR:ENGINE: Could not find ‘@render’ socket.)
meh?

This is definitely not something I can fix
You should consider adding an issue on GitHub, including more information about your system:

Edited my post, before spotting (refreshing to) your reply, drat. I lack knowledge required to understand what is occurring here. Could be something up with my old graphics card or something else on my system, I don’t know.

I remember this now, this comes from Defos, but it shouldn’t cause a black screen or any kind of a problem…

Can you try by commenting this line like this -- init_defos()

github.com/selimanac/defold-daabbcc-example-platformer

scripts/loading.script

17cb4af89


      
          function init(_)
          	data.game.is_mobile = device.mobile() or device.tablet()
          	data.window_scale = window.get_display_scale()
          
          	--  lazy way for mobile camera bounds
          	if data.game.is_mobile then
          		const.CAMERA.BOUNDS_MIN = const.CAMERA.MOBILE_BOUNDS_MIN
          		const.CAMERA.BOUNDS_MAX = const.CAMERA.MOBILE_BOUNDS_MAX
          	end
          
          	init_defos()
          
          	msg.post(const.PROXY.SCRIPT, const.MSG.LOAD_GAME)
          end
          
          function on_message(_, message_id, _, _)
          	if message_id == const.MSG.LOAD_GAME then
          		check_missing_resources()
          	elseif message_id == const.MSG.DOWNLOAD_ARCHIVE then
          		download_archive()
          	elseif message_id == const.MSG.PROXY_LOADED then

It’s weird that you’re getting the same error with the Linker sample game, it doesn’t use Defos at all. I don’t know

imgui Opengl only (probably say this above somewhere ) ?
With Vulcan:

dmengine: upload/imgui/src/imgui/imgui_impl_opengl3.cpp:401: void ImGui_ImplOpenGL3_NewFrame(): Assertion `bd != nullptr && "Context or backend not initialized! Did you call ImGui_ImplOpenGL3_Init()?"' failed.

This results in the following errors:

ERROR:GRAPHICS: Vulkan Error (../src/vulkan/graphics_vulkan.cpp:1401) VK_ERROR_OUT_OF_DATE_KHR
dmengine: ../src/vulkan/graphics_vulkan.cpp:1401: void dmGraphics::VulkanFlip(HContext): Assertion `0' failed.

...

Maybe something wrong with my libc or my graphics card is not compatible, no idea. I am chasing shadows here, Opengl works and that is good enough for me for now.
