Nostalgia v0.17.0 - Alpha 17

Major Changes

• FileSystem
  • Added new functions for generating a unique filepath if it points to an already existing file/directory
    • FileSystem::MakeUniquePath
  • Improved the FileSystem::Write and FileSystem::Read functions
  • Implemented new FileSystem::Lazy::Write functions which perform filepath testing and will automatically rename the path, overwrite the file, or exit with an error depending on the given FileSystem::OverwriteAction argument
• Image
  • Image::SaveJPG writes the stored image data to a file at the given path
    • This uses FileSystem::Lazy::Write to rename conflicting filepaths and stbi_write_jpg to write image data to the given filepath
  • Overhauled file loading vs direct data setting
    • Image::CreateFromData now assumes the given data is already formatted and does not call any STB functions
      • This is used when getting image data directly from frame/texture buffers.
    • Image::CreateFromFile is the new function used to create an image from a file (either via filepath or from memory)
  • Similar changes were made to Image::LoadFile and Image::SetData
• OpenGLRendererAPI
  • Implemented a function for saving the entire default framebuffer to an Image
  • Implemented a function for binding FrameBuffer objects
    • By default, binds the default framebuffer (e.g. glBindFramebuffer(GL_FRAMEBUFFER, 0))
• RenderBuffer/OpenGLRenderBuffer
  • Implemented a class for abstracting render buffers
    • Very basic stuff for now; constructors, destructor, id getter, and a function for initializing storage
• TextureBuffer/OpenGLTextureBuffer
• TextureBuffer::GetImage gets and dumps the texture buffer's current data into an Image
• OpenGLTextureBuffer now only uses gl4 DSA functions
  • No more glTexImage2D and the like, which also means no more mutable storage; if you wanna resize a texture buffer, you gotta make a whole new buffer
• Viewport/ViewportTexture
  • Viewport::Attach binds the framebuffer and resizes the renderer's viewport
  • Viewport::Detach unbinds the framebuffer
  • Viewport now holds a RenderBuffer, TextureBuffer, and FrameBuffer and is in charge of controlling all of them
    • In the future, I'd like for ViewportTexture to take over responsibility of the texture and maybe even render buffers
  • ViewportTexture acts as a direct pass-through to its Viewport for now
• Camera3D/Camera2D/Theatre
  • Camera3D::Draw and Camera2D::Draw now take over drawing logic, replacing Theatre::Draw3DThinkers and Theatre::Draw2DThinkers
  • Camera3D::DrawBackground now takes over drawing the background/skybox
• Implemented RenderManager::IsAPIActive as a better way of checking that the renderer API both exists and is activated

Minor Changes

• Fully implemented ThingVar number type fix from 9d37031
• Added more file-related Error values
• Re-introduced SafeReturn
  • It's currently only used by a few new functions in FileSystem and will most likely be used sparingly
• Implemented FileData::SetData for directly setting file data; this function also allows you to set the filepath if you wish
  • Now FileData really is just a std::vector<uchar> wrapper
• OpenGLRendererAPI doesn't save the clear color to a variable anymore
• Implemented Thing::Invalid for quickly checking if a Thing was created using the string name constructor or not

GitHub PRs

• Indev/v0.17.0/screenshots by @Electron7-7 in #95

Full Changelog: v0.16.2...v0.17.0

Nostalgia v0.16.2 - Alpha 16

Hot Fix

• Stop the frame profiler window from constantly setting its position

Full Changelog: v0.16.1...v0.16.2

Nostalgia v0.16.1 - Alpha 16

Hot Fix:

• Changed how a numeric ThingVariable's number type is derived, fixing an issue where setting a float variable to a whole number would force it to be an integer variable with no way of changing it back
  • A full fix for this will be included in v0.17.0

Full Changelog: v0.16.0...v0.16.1

Nostalgia v0.16.0 - Alpha 16

Major Changes

• Major overhaul of the editor including, but not limited to:
  • A revamped inspector window that uses ThingData to update Thing variables instead of relying on hard-coding everything
  • Re-sizeable camera viewports
    • Additional 2D viewport
  • The editor fully covers the screen and stays in the background
  • Improved frame profiler
  • Improved Thing adder
    • Including name searching
  • Loading the current editor state into a playable Theatre and vice-versa
  • More robust Thing selection for certain variables
  • Fully implemented BitMask interface
• Replaced many ID variables in various Things with pointers
• Implemented Camera2D's zoom functionality
  • This implementation uses the view matrix instead of directly fiddling with glm::ortho
• Fully implement type priority in ThingFactory
  • Implemented TheatreData::sort_by_priority which sorts its ThingData vector by type priority
• Implemented a FileData constructor that takes a string, file type, and optional filepath override string as arguments
  • This is used to perform file operations on files in memory, forgoing the need to actually make files
• Implemented mouse scroll-wheel input events
• Implemented a custom EditorTheatre class for the editor that doesn't update/tick Things and renders special meshes/sprites for specific types (e.g. Camera3D mesh)
• Better implement BitMask as its own ThingVariable type

Minor Changes

• New models for PointLight3D and SpotLight3D when viewed in the editor
• Add a boolean argument to the string version of ThingData::set_variable which will accept an empty string variable
  • The string version of ThingData::get_variable has been changed to not ignore empty string variables
  • This is used in Text2D::SetVariables
• Improved the body activation code in Collider3D
• A loaded Theatre file now stores its full path instead of just the directory
• Implemented getting raw Theatre save data as a string, via Theatre::GetSaveData
• Implemented a function for copying data between different Theatre-derived classes
• Implemented a function in TheatreManager for changing the next loaded Theatre's type
• nullptr exception safeguards in various renderer-related functions

GitHub PRs

• Indev/v0.16.0/bitmask and editor by @Electron7-7 in #94

Full Changelog: v0.15.0...v0.16.0

Nostalgia v0.15.0 - Alpha 15

Major Changes

• Add a function to ThingFactory for getting the map of all Thing type declarations
  • Integrate Thing type declarations into ThingFactory::IsThing and ThingFactory::IsDerivedFrom
• Add ThingVariable::thing_type
  • This variable is used by 'ID', 'Child', and 'Parent' variables
• Integrate BitMask into the number-related functions in ThingVariable
• Implement special named numbers into the parser
  • These can be used with number variables to represent specific pre-determined numbers (used mainly for bitmasks)
• Removed NostalgiaPlayer3D and replace it with NostalgiaPlayer
  • NostalgiaPlayer derives from Thinker and contains two pointers, an Actor3D and an Actor2D. These pointers can be assigned to actors in a Theatre file, and can be thought of like the 3D/2D components of a player

Minor Changes

• Tick rate and interval profiling are disabled by default in the debugger
• Implement TheatreData::get_log and TheatreData::get_parseable_string
• Improve the Theatre file parser
• Changed how Camera2D, Camera3D, Visual2D, and Visual3D set/get their BitMask variable
• Various editor/debugger improvements and features

Full Changelog: v0.14.0...v0.15.0

Nostalgia v0.14.0 - Alpha 14

Major Changes

• Replaced Mesh with ArrayMesh
  • Mesh now acts more like a pure virtual class (without actually being one, as that's not yet supported)
  • ArrayMesh now has an extra function for loading a model file directly/creating an ArrayMesh from a model file
• Updated OpenGLVertexArray, OpenGLVertexBuffer, and OpenGLIndexBuffer
  • Implemented more modern gl4 methods
  • Added debug data query functions (very non-performant; strictly for debugging purposes)
  • Removed the empty, default constructors from the mesh buffers (e.g. VBO & EBO/IBO)
  • Redesigned how the buffer layouts and vertex buffers themselves are implemented
    • I understand now that the reason for having multiple VBOs per VAO is to buffer separate vertex attribute data into separate VBOs. The changes I made better reflect this use case (and utilize modern gl4 methods, thus being more efficient)
• Created the idea of a mesh surface/shape via Mesh::Surface
  • Mesh::Surface is a data struct containing the relevant information for drawing a mesh surface:
    • Primitve type
    • Vertex array
    • Material ID (unused for now)
  • Mesh declares (and gives default definitions to) multiple functions for interfacing with a mesh's various surfaces
  • ArrayMesh defines these functions and maintains a vector of Surfaces
  • Rewriting the OBJ-processing code to use Surface also resulted in me no longer needing the Vertex struct or code
• Improved the 'set-' functions in TheatreFile::ThingData
  • If the variable being set already exists, it is replaced instead of being duplicated
  • Added a new ThingData::set_enum_variable function for setting an enum variable with only the name of the enum (the value is acquired via a new function in EnumRegistry)
• Fully overhauled the editor to be more programmatic and less hard-coded
  • Some features are missing, like the ability to select bitmask flags for certain variables, but many new features were easily added in, including a more robust Thing UID selector, and safer interactions leading to far fewer crashes
  • Also added some profiling to the debugger, with included graphs!

Minor Changes

• Updated OpenGLRendererAPI to be less prone to crashes and compiler errors
• Fixed a strange issue with FileSystem::GetProgramDirectory on Windows
• Implemented next-closest type declaration functions in ThingFactory
• Added more functions to Theatre for getting the UIDs of all Thinker or Resource things, as well as all orphaned Thinkers
  • Also added functions for locking specific mutexes
• Added a function to the EnumRegistry for getting an enum's raw data value with only its string name
• Added a function to the EnumRegistry for getting all enums of a specific category (e.g. enum EnumCategory...) with only the name of one enum in that category (e.g. EnumCategory::Enum)
• Added a function for discerning the type of number a string represents in (number_parser.hpp)[Nostalgia/theatre/parser/number_parser.hpp#L101)

Nostalgia v0.13.0 - Alpha 13

Major Changes

• Thing::rename and Thing::SetNameChangeCallback

Full Changelog: v0.12.0...v0.13.0

Nostalgia v0.12.0 - Alpha 12

Major Changes

• Removed UID's functions and gave them to Thing to manage its own uids
• Overhauled how Theatre starts up and creates Thing objects
• Overhauled how Viewport, Camera3D, and Camera2D interact with eachother
  • This includes the added improvement that the "root viewport" is no longer a Viewport object tied to the Theatre
• Added an IsRunning query to the renderer API
  • Implemented WindowGLFW toggling it before calling glfwTerminate
  • Implemented querying this value before calling gl- functions in most backend classes
• Improved library linking when building the editor/test apps

Minor Changes

• Optimized Thinker relationship setup
• Added some debug Console variables
