Vulkan Nitty-Gritty

I am surprised at how quickly Vulkan development is coming together. The API is ridiculously verbose, but at the same time it eliminates a lot of hidden states and implicit behavior that made OpenGL difficult to work with. I have vertex buffers working now. Vertices in the new engine will always use this layout:     struct VkVertex     {         float position[3];         float normal[3];         float texcoords0[2];         float texcoords1[2];         float tangent[3];         unsigned cha

Resizable Vulkan Window

When a window in Vulkan resizes you have to manually delete the about a dozen objects and then recreate them with the new size. It's unbelievably complicated. They've pushed all the driver complexity onto the application, in an effort to simplify the job of writing drivers. I can see the advantage to this, because OpenGL drivers in the past were always inconsistent, but it is still shocking how many little details they expose in Vulkan. Just resizing a window and swapping the screen buffer invol

Hello Vulkan

Hello Vulkan

Two days and 823 lines of code later, I present to you the Vulkan triangle of awesomeness, running in our engine: Here are my thoughts on Vulkan: It's ridiculously verbose. You have to specify every little detail of the rasterizer, there's a million classes to create, and every little variable has to be exactly right. There's really no reason for this because 90% of the code is just something you copy and paste. Shaders can use GLSL, which seems very weird, but it makes thin

Getting Started with Vulkan

Getting Started with Vulkan

The latest design of my OpenGL renderer using bindless textures has some problems, and although these can be resolved, I think I have hit the limit on how useful an initial OpenGL implementation will be for the new engine. I decided it was time to dive into the Vulkan API. This is sort of scary, because I feel like it sets me back quite a lot, but at the same time the work I do with this will carry forward much better. A Vulkan-based renderer can run on Windows, Linux, Mac, iOS, Android, PS4, an

Dev Log

My last NASA project is complete. There's a physics bug in Leadwerks 4.6 that will get resolved this weekend. Starting Monday I am going to focus on the new engine again and move us forward so we can release in 2020. I am really looking forward to getting back in the game.

Procedural Grass

Thought I'd show off what I've been working on this weekend.  I have implemented procedural grass as found here at Outerra.  There is still more work to be done on it but so far it looks promising.
Stacking Boxes

Stacking Boxes

The stacking of boxes has been successful, this is thanks to the system that has been implemented, kicking the box, carrying a box, and releasing a box. You could make things better, more realistic, such as when the kick and that the tip of the foot of the character to touch the box is flying, but the truth does not matter is just a simple game. At this point everything has been a challenge, and what is done at the moment is just an immersion learning process in the set of tools that L
This continues

This continues

Despite the obstacles you continue with this, a challenge of making a video game, and on the basis of this come a number of questions. Why do you do it?, What do I get from this?, the truth is nothing, nothing matters, for some reason with the passage of time, I've noticed and I think I've already said it once, this is a hobby, that if it ends in something, it would be great, but if it doesn't, everything is fine. The inconveniences at the moment, the ban of the steam account, I think it wa

New game engine examples

The new game engine needs to roll out with some top-notch examples showing off what it can do. Here's what I want: First-person shooter Offroad racing game Space shoot-em-up side-scroller. Side-scoller platformer similar to the Contra Playstation game. Now what I can use your help with is finding good example games on YouTube or Steam that I can start designing these samples around. Post your ideas below!

Smart Pointers Lesson

This is something I typed up for some colleagues and I thought it might be useful info for C++ programmers. To create an object: shared_ptr<TypeID> type = make_shared<TypeID>(constructor args…) This is pretty verbose, so I always do this: auto type = make_shared<TypeID>(constructor args…) When all references to the shared pointer are gone, the object is instantly deleted. There’s no garbage collection pauses, and deletion is always instant: auto thing = m

Leadwerks Game Engine 4.6 Release Candidate

An update is available on the beta branch on Steam with a few bug fixes. I'm going to release 4.6 with the current features because a lot of bugs have been fixed since 4.5 and we're overdue for an official release. 4.7 will add a new vehicle system, character crouching physics, and some other things, and will be out later this year.

GDC 2019

I have not gone in several years because everything we were doing revolved around Steam, and it just didn't seem very important. But this year I had some business to attend to so I spent the last three days in San Francisco. I still have a lot of friends in the game industry, and the reaction to my plans for the new engine was very positive. A few years ago people would have groaned at the idea of another engine, but it seems they are now bored with technology and very open to something new
