Pragma - A 3D multiplayer sandbox engine with Lua-integration, based on Vulkan and bullet physics - Developers

[QUOTE=Silverlan;52311088]No, this has nothing to do with the source engine (Aside from the fact that my engine supports some of source's file formats). I wrote the engine from scratch, no code from source was used.[/QUOTE] Yeah I read that, I only said it that way because it's a pretty similar concept of "X but without the old engine's limitations". What I mean is it's purpose to basically do what Gmod does without Source's limits (seeing as that seems to be it's main appeal).

[T]http://sciolyte.com/sharex/2017-06-08_17-29-23.gif[/T] Missing models, materials and sounds are now automatically looked up in .vpk-files of installed source games, extracted, converted and/or copied automatically. Also works with .bsa and .ba2 archives from fallout and elder scroll games (still work in progress): [T]http://sciolyte.com/sharex/2017-06-08_20-14-41.gif[/T]

Much love friend!

My friends and I actually really tried to give it a go today, but it crashed a lot, we couldn't keep it stable for like over 10 minutes without standing still and doing nothing, and instantly crashes whenever a third person joins the game.

I've added support for ZeroBrane Studio, which is a Lua IDE with debugging support: [video]https://youtu.be/ei8TRkW83Sc[/video] Video turned out a little squashed, I'll record a proper one soon. You can basically add break points to your code and execute it step-by-step, I haven't played around with it much, but it looks promising. [EDITLINE]-[/EDITLINE] I've recorded a proper video now which should depict it a little better: [video]https://youtu.be/pm73zJIQwUo[/video]

Made some more improvements on the porting system for source models, ragdoll physics are now ported properly, and I've made some general improvements on ragdoll stability: [video]https://youtu.be/PAag7I_qmac[/video] [T]http://sciolyte.com/sharex/pragma_2017-06-18_11-46-39.png[/T] All you have to do is set the model, and the engine ports everything automatically. As far as I can tell it works with almost all source models now (Haven't found any problematic ones). Still have to tweak some minor things such as phong values though (Breen's suit is a tad too shiny...).

[video]https://youtu.be/vJphoc62EH8[/video] Long video, just skip to around ~11 minutes in to see some results (Skip from minute to minute if you don't want to watch all of it). It's mostly just a demonstration for the live coding and the debugger. [sp]That thumbnail though.[/sp] :v:

A very pragmatic solution

Pragma doesn't sound as cool like Sciolyte.

Added bone-scaling support: [T]http://sciolyte.com/sharex/2017-06-23_12-46-32.gif[/T] Also forgot to mention that I've added HRTF-support when I revamped the sound system a short while ago. The effect is subtle, but makes quite a difference if you have headphones. Here's a comparison of regular surround sound and surround sound with HRTF in CS: GO: [url]https://youtu.be/4BltHXngvlk[/url] It's especially noticable if the sound is coming from somewhere above or below your position.

I've been reworking some parts of the addon system over the last week: [video]https://youtu.be/rN84vp6NDxs[/video] • Addons can be downloaded and mounted during runtime • Addon updates are downloaded automatically when available • Only changed/added files are downloaded, so you don't have to re-download the entire addon every time there's an update • Downloads can be suspended and resumed later • All files are compressed • Lua-files are automatically pre-compiled and stripped of debug information Just need to give it the final touches.

Are there any specific requirements to running pragma? As i can't seem to get it launching with my system.

[QUOTE=Azalia;52426494]Are there any specific requirements to running pragma? As i can't seem to get it launching with my system.[/QUOTE] I've published an update today which should fix a few crash instances, can you give that a try? If that doesn't work, try updating your graphics drivers. Other than that, I can't really say without more information (Any error messages? Crashdump?).

Quick question, how much space does Pragma currently need? I might try it out, but need to make some more space.

[QUOTE=McDoomington;52446519]Quick question, how much space does Pragma currently need? I might try it out, but need to make some more space.[/QUOTE] It's about 1.32 GiB. Anyway, not much new to show off, I've mostly been working on some bug-fixes and I'm updating all of my addons from the modding hub to the latest version with the new addon system. Not entirely sure what I'll be working on next, I might just create some more example NPCs. Here's the latest changelog: [CODE]Pragma ChangeLog Version 0.3.1 08 July 2017 - Added Animation:SetBoneWeight, Animation:GetBoneWeight and Animation:GetBoneWeights - Layered animations can now override base bone transforms - Fixed view particles lagging behind by 1 frame - Fixed view models not being rendered if occlusion culling is set to octree - Fixed occasional issues with animations imported from source models - Removed map "fork" 07 July 2017 - Added Material:GetDataBlock - Added material parameters "phong_diffuse_alpha" and "phong_normal_alpha" - Added sprite parameter "black_to_alpha" - Added missing gmod archives for mounting system - Fixed physics issues for ported models from source engine - Class "DataBlock" is now shared instead of clientside only 06 July 2017 - Added Weapon:SetViewModelOffset, Weapon:GetViewModelOffset, Weapon:SetViewFOV, Weapon:GetViewFOV, Animation:SetFadeInTime and Animation:SetFadeOutTime - Changed overloads for Entity:FireBullets - Fixed crash on some GPUs when a weapon shell is ejected - Fixed several shader crash instances - Fixed "HandleViewModelAnimationEvent" weapon callback not working 05 July 2017 - Added new overloads for Entity:AddAnimationEvent - Fixed various shader crash issues on some GPUs - Improved Lua error handling 04 July 2017 - File write-operations can now only be performed by Lua-scripts inside addons, and files can only be written within that addon - Moved all functions and enums from "cvar" library to "console" library - Moved "engine.create_light", "engine.remove_lights", "engine.create_sprite", "engine.precache_model", "engine.create_material", "engine.create_particle_system", "engine.precache_particle_system", "engine.save_particle_system", "engine.precache_material", "engine.create_texture", "engine.load_sound_scripts" and "engine.load_material" to "game" library - Removed "cvar" library 03 July 2017 - Moved classes into appropriate libraries - Renamed "physenv" library to "phys" - Moved "game.raycast", "game.sweep" and "game.overlap" to "phys" library 02 July 2017 - Added function "game.is_game_mode_initialized" - Addons can now be mounted during runtime - Revamped addon system - Fixed file reading from archive files sometimes skipping last byte - Fixed crash issue on some Nvidia GPUs - Fixed lua_compile not stripping debug information Version 0.3.0 25 June 2017 - Fixed various issues with Nvidia GPUs 24 June 2017 - Added Scene:GetLightSources, Scene:CullLightSources, Scene:GetCulledLightSources, vulkan.get_swapchain_buffer_count and vulkan.get_swapchain_image_index - Fixed scenes using all light sources instead of just the ones assigned to them - Renamed Scene:SetLights to Scene:SetLightSources - Updated Vulkan to version 1.0.51.0 [/CODE] [EDITLINE]-[/EDITLINE] Just tested the model loader with models from black mesa, looks like that works as well (Mostly, bullsquid's eye textures seem to have some trouble): [T]http://sciolyte.com/sharex/pragma_2017-07-08_23-03-46.png[/T] [T]http://sciolyte.com/sharex/pragma_2017-07-08_23-07-45.png[/T] [T]http://sciolyte.com/sharex/pragma_2017-07-08_23-08-48.png[/T]

Would you mind adding UNICODE name support? Currently it will eat characters instead of error represent or attempting to display, and does not interface with IMEs properly.

[QUOTE=YOMIURA;52491672]Would you mind adding UNICODE name support? Currently it will eat characters instead of error represent or attempting to display, and does not interface with IMEs properly.[/QUOTE] I've just published an update which should fix extended ASCII characters not being displayed. Beyond that I can't really do much since the fonts I'm using don't have unicode characters. (I don't think there are many free fonts with a full unicode character set.) I'll keep an eye out for a new font to use with a full unicode set. Anyway, to anyone who hasn't seen it yet, I've created a new thread in the "Videos And Flash Movies" sub-forum where I'll be posting update news from now on: [url]https://facepunch.com/showthread.php?t=1572105[/url] I'll keep using this thread for anything programming-related.

This is fantastic, honestly. It's coming along really well.

This seems to be coming along slowly but surely. That is to be expected with but a single person working on it though, this deserves more community support. I'm sure that if more people from the community started helping making this a stable, playable engine, then lots of people would want to play which would then make more people interested in helping, and the cycle continues.

Will it be a closed source forever?

not sure if this has been asked already (rate me dumb if it has), but is this going to remain free? [editline]31st July 2017[/editline] i guess the above post is semi-related, oops

Not sure if this was already answered or not, but one of the greatest issues in Garry's Mod was the inability to parent contraptions properly. Will this be remedied within this engine?
