In systems such as iOS, Android, Wii U, etc. applications can be "paused" by the user (by exciting the app, pressing the home button, etc).Support to intercept these events is quite important, as often the GPU must be reset and primed when switching back.

Thus, I propose the addition of pause/unpause events/callbacks.

Spine stuff needs to get integrated somehow into the main project, probably as a submodule.

Frag needs a Logo.

Hi @zacharycarter
I have installed Frag and built some examples, but seems one dll is necessary to run examples: bgfx-shared-lib(Debug|Release).dll.
Can you please tell me how to find or generate it?

Thanks!

Mipmaps should be able to be generated (optionally and automatically) during texture loading.

http://docs.gl/gl3/glGenerateMipmap

Currently spritebatch is just allocating transient buffers all willy nilly. Should call check first before allocating buffer.

Support loading / unloading of BMPs. Header bytes should be verified.
https://oroboro.com/image-format-magic-bytes/

Image loading / unloading should be performed with sdl2_image :
https://www.libsdl.org/projects/SDL_image/docs/SDL_image_frame.html

OpenGL code related to texture loading should be moved into a common proc.
https://github.com/fragworks/frag/blob/master/src/frag/graphics/two_d/texture.nim#L59-L71

We need 2d particle effects.
https://github.com/bkaradzic/bgfx/blob/master/examples/32-particles/particles.cpp
http://buildnewgames.com/particle-systems/

Not sure what the best way to do this is. The former is probably better for 3d particles and something like the latter for 2d.

We need some kind of web presence for FRAG.

I don't really care how we do this - I'm thinking a github pages site would suffice.

We're at the stage where we could really start using some help in producing documentation and write ups about how to build the project on different platforms, how to compile shaders, etc... Information I can already start dispensing that is unlikely to change much, but without it, users will be quite puzzled as to how to use the project.

Not only that, but it'd be nice to start generating a little more buzz about the project. This is something we could work on in our down time, but we should start moving on ASAP IMO.

My buddy is working on the logo as far as I know, so as soon as that's ready it'd be sweet if we had something to drop it into and go live with.

I don't see any release tasks for linux in nake. I'm assuming it's on the way at some point?

Tiled map API is very basic.

Add additional procs for -
know / get the size (AABB)
translate it on render?

Also -
provide way to render w/o calling begin and end on spritebatch

Need to support loading the following formats :

1. https://www.codeandweb.com/texturepacker (JSON)

2 options being explored -

1. Wrap existing C Spine runtime

• Will force us to include Spine runtime license with project, but project can be optionally included with FRAG so FRAG can stay spine runtime license free
• Faster and easier

2. Write our own runtime

• Not fast, not easy
• WIP atm, working on parsing skeleton and texture atlas data
• Will need extensive testing to verify results against spine samples

Out of the two options, I'm much closer to achieving # 1. I think if I took another shot at creating bindings I could probably have something working in a day or two.

`# 2 is more appealing though, so I'm working on that. If I encounter roadblocks I may switch back to # 1.

Trying to link bgfx on ubuntu produces the following error :

Hint:  [Link]

could not load: libbgfx-shared-lib(Debug|Release).so
Error: execution of an external program failed: '/home/zc/projects/frag/examples/desktop/00-hello-world/main '

Probably due to linking order / transitive OpenGL dependency.

Port this, but make the ranges [0,1] instead of [0,255].

Need to write code to properly dispose of spritebatch instances.

Integrate Chipmunk2D

Build a sample game for android

FRAG should support drawing primitives. Use cases are:

• for simple game prototypes (or just games with a very simple visual style)
• for debug and "editor" gui systems - eg. drawing bounding boxes, "handles" to resize, move objects etc.

As a list of possible primitive to start with, I would suggest something like that supported by sdl2, ie:

• lines
• points
• rects
  with filled and non-filled variants.

See the discussion on the forum here: http://community.fragworks.io/t/possible-feature-request-drawing-primitives/19 ( @zacharycarter has some implementation suggestions here. )

Need to integrate NanoVG for a HUD solution.

Need a GUI submodule which should utilize Nuklear IMGUI

edit: I got the example to compile but when I run I now get: could not load: libbgfx-shared-lib(Debug|Release).so
I downloaded frag git and installed with nimble. Docs say that will install deps. I have these packages installed: libgl1-mesa-dev x11proto-core-dev libx11-dev

Placeholder.

We need some kind of discussion board / forum for the website.

We can discuss categories and shit later, but for now I'm thinking we just have an announcements section, a general section, and a help section.

I honestly hate having anything to do with message boards besides post on them, and I don't know how you feel about them @rosshadden but I feel like the administration / moderation of them is something we could hand over to someone else who'd be willing to help out contribute. I doubt that will happen till we have more steam behind us, so that might fall to us for now.

I'd like to try to get set up with something soon though, the simpler and faster the better.

May I suggest you to modify references like git@... from .gitmodules, using
https://.. instead ?

Support for tiled maps would be nice.

Should support loading http://www.mapeditor.org/ maps.

See if docker can be used to ease production of shared libs for android.

Need an automated way of building android examples

Make nakefile generate targets from the folders inside the examples folder, by parsing their names.
