hipreme_engine 1.0.13

<p align="center"> <img src="engine_logo.svg" width="300"/> </p>

<h1 align="center"> <a href="https://github.com/MrcSnm/HipremeEngine/wiki/Getting-Started">Getting Started</a> </h1>

The engine maintains some global options which you can modify it on source/global/opts.d:

• HE_DEBUG -> Use that for creating a debug version for the engine only
• HENOLOG -> Disable the global logging functions
• HEERRONLY -> Maintain only error logging

Current features

• Input handler and text input with selected keyboard layout;
• Xbox One/Series Gamepad implementation;
• Minimal Matrix/Vector implementation;
• Asset packing, appending, updating and reading for faster performance(less IO);
• Multi threaded asset loading and decoding (image).

Platforms

Almost all of those platforms can be built by using the build_selector project.

If you have D installed already, the buildselector can be got by running `dub run hipremeengine:build_selector`

If not, you may go to the BuildAssets page and select your system. Both the language and engine will be installed locally by using them.

Build System Showcase

• Xbox Series (UWP): build/uwp
• Android: build/android/
• Browser (WebAssembly): build/wasm
• PS Vita: build/vita
• MacOS : build/appleos
• iOS: build/appleos
• Windows: bin/desktop
• Linux: bin/desktop

Requires libgl1-mesa-dev for opening X11 window and OpenGL

Features

1. Simple build system
2. Virtual File System
3. Centralized asset locator with caching
4. File reading with progress notification

Rendering

• Metal 2.4
• Direct X 11
• OpenGL 3
• OpenGL ES 3
• OpenGL ES 2
• WebGL 1.0 (OpenGL ES 2 emulated)
• HipRenderer (abstraction)

Features

1. Sprite
2. SpriteBatch
3. GeometryBatch
4. FrameBuffer
5. BitmapText
6. Shader
7. Material
8. Tiled maps

Audio

• AVudioEngine
• OpenSL ES
• OpenAL
• XAudio2
• WebAudio
• HipAudio (abstraction)

Features

1. Streaming
2. 3D audio
3. Low Latency on Android -> See flags at config/opts.d HIP_OPENSLES_OPTIMAL and HIP_OPENSLES_FAST_MIXER

Decoding

• Images: PNG, JPG, BMP, TIFF and maybe others via arsd-official:image_files
• Audio: MP3, OGG, WAV, FLAC via audioformats
• Tiled: TSX and TSJ parser
• TextureAtlas: JSON, ATLAS, XML and TXT(Spritesheet) parser
• Font: FNT, TTF, OTF
• Pack: HapFile(Hipreme Asset Packing File)
• Settings: INI/CONF, JSON (HipremeEngine own's implementation that simulates std.json but faster) and CSV

Coding

• Scripting:

1. D ( check api module for reference )

• Filewatcher for recompiling the script
• WebAssembly server reloader
• Live reload ( no engine restart for coding )

  State is not saved, it is a simple restart, but all the assets are also cached, so, it is still way faster than reopening.

1. Lua (outdated)

• May be subject to removal

Next steps

• GLSL to HLSL transpiler
• Multi threaded audio decoding (currently only single threaded is supported)
• Create a proof of concept

Issues list

• You can't spawn an Object from within an interface without calling hipSaveRef or GC.addRoot. This is a bug on DLL implementation which doesn't actually add the new object spawned from an interface as a leaf.
