Cross Platform D-Lang Game Engine with scripting support

Getting Started

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
• HE_NO_LOG -> Disable the global logging functions
• HE_ERR_ONLY -> 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 build_selector can be got by running dub run hipreme_engine: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.

2. 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.

hipremeengine's Issues

`setFont()` interferes with `drawRectangle()`

setFont() interferes with drawRectangle() and makes it actually fillRectangle().

double setFont()

override void render()
{
    setFont(smallFont);
    drawRectangle(40, 40, 200, 200, HipColor(1, 0, 0.5, 1));
    setFont(null);

    renderGeometries();
    renderTexts();
    renderSprites();
}

no or single setFont()

override void render()
{
    drawRectangle(40, 40, 200, 200, HipColor(1, 0, 0.5, 1));
    setFont(null);

    renderGeometries();
    renderTexts();
    renderSprites();
}

It makes no difference whichever one is omitted. Bug only occurs when both are there.

Update Rmd File

I have fixed a spelling mistake and would like to suggest the item as a class 3 action item 8516f14.

windowing: Linking fails on Debian

…/HipremeEngine/projects/start_here$ dub -c run
ld: error: cannot open /usr/lib/gcc/x86_64-linux-gnu/10/../../../x86_64-linux-gnu/X11: Is a directory

Seems like the cause is the following line:

HipremeEngine/modules/windowing/source/hip/windowing/platforms/x11lib/x11.d

Line 10 in 494b67b

pragma(lib, "X11");

X11 should probably be x11 here.
Furthermore, this pragma seems kinda redundant, as the lib is scheduled for linking in the DUB recipe already:

HipremeEngine/modules/windowing/dub.json

Line 9 in 494b67b

"X11",

Funny enough, linking seems to work fine with a capital X here.

Oh and: This is on Debian 11 “Bullseye” on an x86-64 machine.

It's dub time! (compilation errors)

Hey, just had another error when doing a standard bog dub command on my terminal, here let me paste:

Audio modules error

Hi! Immediately after updating your repo and getting everything right, I got another issue using dmd, here:

modules/audio/source/hip/hipaudio/audioclip.d(43,5): Error: static assert: "HipAudioBuffer must have same size as a ptr, _getBufferAPI depends on that"
Error /usr/bin/dmd failed with exit code 1.

Running a standard dub, Debian 11 once more.

Basic building system for Web(WebAssembly)

Create a build system for web, linked repo: https://github.com/Ace17/dscripten

start_here: DUB postGenerateCommand assumes Windows

The postGenerateCommand in the DUB recipe of the start_here project assumes that the user is running Windows (or any OS with backslash \ as its directory separator).

HipremeEngine/projects/start_here/dub.json

Line 51 in 40eeb64

"postGenerateCommands": ["cd ..\\..\\ && dub -c script -- .\\projects\\start_here"]

On other platforms building fails with /bin/sh: 1: cd: can't cd to .... or similar.

Building on Linux hits an error related to XAudio

Hi. I wanted to know if DMD is supported or not? Since it seems that when I'm building through a 'dub build' command I hit:

modules/audio/source/hip/hipaudio/audioclip.d(57,25): Error: undefined identifier XAUDIO2_BUFFER
Error /usr/bin/dmd failed with exit code 1.

And I am not sure why that is happening since Linux does not uses xaudio at all to my knowledge, I built from master too. Perhaps I have to use LDC instead of DMD for a successful compilation? Does the projects states that so? (Or you're not supposed to use dub?)

@nogc Logging

1. Make Console @nogc, as it is not really necessary. Specially now that we have betterC strings, (and conversions).
2. Change logging arguments to compile time variadic arguments. FILE, PRETTY_FUNCTION and LINE should not be template arguments
3. Remove _formatPrettyFunction, probably it is a waste.

FR: MOD/XM/S3M/IT support

This is something of an optional thing but I think it'd be pretty useful to showcase be it on gamejams or technical demonstrations of the engine. These formats are known for being made from a program known as a tracker, and they contain sample data and everything needed to run standalone. I was wondering if it would be feasible or possible to have this added on the HipremeEngine?

Cannot build on latest master

Hi! I did a fresh new git pull origin and clone and I got these errors now:

Implement a Scene Graph

Scene Graph is pretty important for 2D and 3D games, helps a lot into managing a lot of objects at the same time, its almost time to implement that.

Change Utils to hipstd

Utils has gone a step beyond being just an utils. It is an entire stdlib for the D programming language. I'll need some time converting the names and references to it.

Attempting to resize or move the screen may cause an unresponsive white screen to appear (Linux)

Hey so it finally built! Though not without its issues. If I attempt to close the application (without turning off the terminal) it does not responds to that action, also, slight resizing of the window causes the entire program to go blank at prompt and stay unresponsive as well. This is all on X11, though it could also be an Xfwm bug (though not so sure about that either)

Linking error related to /TIME on Linux

Hey there, been awhile. I was updating the repository and I encountered a bug where attempting to run a dub or dub build command nets me a: /usr/bin/ld: cannot find /TIME: No such file or directory
collect2: error: ld returned 1 exit status
Error: linker exited with status 1
Error /usr/bin/dmd failed with exit code 1.

Not sure what is happening here though

2nd run of the generated project doesn't run

After a project is generated:

First run of dub -c run --compiler dmd run the game.
Repeating dub -c run --compiler dmd doesn't run the game.
I didn't expect that.

Here the 2nd run result:

Using dub -c run --compiler dmd -f makes it run again.

Key out of range

Hello,

Engine sounds very promising!

How to reproduce:
On Windows, when I press the Fn key, or the "sound mute" key on my keyboard, the engine closes with message:

core.exception.AssertError@source\hip\event\dispatcher.d(270): Key out of range
----------------
0x00007FF76476EB49 in d_assert_msg
0x00007FF76461CD9B in hip::event::dispatcher::getHipKeyFromSystem at C:\Users\guill\Desktop\HipremeEngine\source\hip\event\dispatcher.d(270)
0x00007FF76461C635 in hip::event::dispatcher::EventDispatcher::this::__lambda2 at C:\Users\guill\Desktop\HipremeEngine\source\hip\event\dispatcher.d(58)
0x00007FF76472C8CD in hip::windowing::platforms::windows::WndProc at C:\Users\guill\Desktop\HipremeEngine\modules\windowing\source\hip\windowing\platforms\windows.d(61)
0x00007FFB93B58231 in DispatchMessageW
0x00007FFB93B57A7B in CallWindowProcW

0x00007FFB93B58231 in DispatchMessageW
0x00007FFB93B57CF1 in DispatchMessageW

Expected behaviour: key being ignored instead of closing game.
So cannot hit F5 on that keyboard for now since I need Fn key

No ldcVersion specified, your HipremeEngine will attempt to install locally LDC2 1.36.0-beta1
	This compiler version is installed locally and won't affect your system D installation.
Your system will download a file: Download D cross compiler LDC2 1.36.0-beta1(https://github.com/ldc-developers/ldc/releases/download/v1.36.0-beta1/ldc2-1.36.0-beta1-linux-x86_64.tar.xz) [Y]es/[N]o

I do not like that.

Is there a way to not do that, and use system ldc by default?

Also please DO NOT do terminal reset, before printing this message. It screws things up (i.e. hard to copy build logs).

Additionally pressing N, causes terminal to be in-non-echo mode forever (until reset). Please do not touch echo mode. Require Y+Enter instead.

Not sure if example working?

I was kindof expecting something on screen, but the generated project is a black screen.
What I was expecting: anything else, even a plain non-black color rectangle, so that I know the engine is working as intended.
What I see: black window

Not sure what is going on here admittedly, though so close to being compiled now! (not sure if this is something related to my linker, or the codebase, or something else entirely even)

ninepatchtest.d incompatible types

Hey! Thanks for taking notice so soon of my reported issue. I noticed that an hour ago or so a new PR was released and most of it was compiling! There is still this error that I'm running into though

source/hip/view/ninepatchtest.d(32,29): Error: incompatible types for (getTouchPosition(0u)) - (this.startPatch): float[2] and Vector!(2u, float)
Error /usr/bin/dmd failed with exit code 1.

I do appreciate that most modules and the audio ones were fixed!

Make the Renderer and Audio classes optionally structs

This could take a long time. For integrating with betterC, classes can't be used, unless someone have a better idea on how to solve that. We could have a special version which would actually use only one renderer and only one audio player. No dynamic switch via the .conf file.

Onboarding

• I took a long time to find the link to: https://github.com/MrcSnm/HipremeEngine/wiki/Getting-Started#getting-started

  • first I tried to look into "projects"

  • then I tried "start_here" in projects. But, not sure what it is in the end, doesn't build with strange DUB error
    

  • then I tried to open HipremeEngine.sln, but does not open correctly in VS

  • then I found the big link in README.md, in editor did not really noticed that link before

• follow the tutorial in Getting-Started

• Got a build error:
  

Allow trailing slashes in paths for the script loader

It would be nice if the script host/loader would allow paths with trailing slashes.

works: bin/desktop/hipreme_engine ./projects/start_here
doesn’t work: bin/desktop/hipreme_engine ./projects/start_here/

Rationale

• I fail to remember which one the correct one is (trailing slash vs none).
• Bash completion supplies the path with a trailing slash

BetterC Arrays

BetterC Arrays could be used instead of plain D runtime arrays. This is great for increasing compatibility with more projects and requires almost no effort. Almost every HipremeEngine backend could be a ref counted array. As the syntax doesn't change much.

Performance could be compared. Although I really don't think that ref counting arrays should have much impact.
