# HandmadeHero
Any code I do for this [series](https://handmadehero.org) will be here.
Any code I do for this [series](https://handmadehero.org) will be here.
***(Only original hand-written code will be here, no code from the series itself)***
## Scripts
* `build.ps1` - Builds the project use `.\scripts\build msvc debug` or `.\scripts\build clang debug`.
* `build.ps1` - Builds the project use `.\scripts\build msvc <args> <module>` or `.\scripts\build clang <args> <module>`
* `debug` adds debug symbols, etc
* `dev` for development builds. (automatically adds debug)
* `optimize` for optimized builds.
* `dev` for development builds. ( Dev memory layout and code paths compiled ).
* `verbose` gives more info on arguments passed to tools, etc.
* `module` is the module to build, can be any of `platform` or `engine` for this point in the codebase. (Eventually game will also be a separate module)
* `clean.ps1` - Cleans the project
* `update_deps.ps1` - Updates the project dependencies to their latest from their respective repos. (Not done automatically on build)
* `update_deps.ps1` - Updates the project dependencies to their latest from their respective repos.
*Make sure to run `update_deps.ps1` before building for the first time.*
@ -20,17 +23,45 @@ Building requires msvc or llvm's clang + lld, and powershell 7
The build is done in two stages:
1. ~~Build and run metaprogram to scan and generate dependent code.~~ (Not needed yet)
2. Build the handmade hero runtime.
1. Build and run metaprogram to scan and generate dependent code for the module being built.
2. Build the the runtime for the module.
Module build order:
1. Engine
2. Platform
## Milestone
Day 028: Drawing a Tile Map
Day 30 : Moving Between Tile Maps
Features Done so far:
* Tailor made build system via powershell scripts
* Supports building the repo with msvc or clang
* Can stage codegen metaprograms to run before building the module
* Will automatically not run if app process is found (for engine module).
* Can emit exported mangled symbols for the engine module for hot-reload with the platform module without needing to use C linkage symbols or a complex hot-reload library (Live++, etc).
* Platform Layer:
* Direct Sound audio
* Keyboard & Mouse Input via GetAsyncKeyState & Win32 window messagng
* XInput controller support
* Dualsense controller support via joyshock library
* Software rendering via Win32 GDI
* Instantaneous hot reload of engine module
* Block Memory allocation via VirtualAlloc for engine module
* Memory mapped files for engine & game snapshots.
* Engine Layer:
* Take & load snapshots of either the engine's or game's memory state.
* Allows for engine or game state to be restored even if a crash occurs to exact memory state it was before.
* Basic input abstraction into hard-coded actions (``EngineActions` & `PlayerActions`)
* Record & replay input.
* (WIP) : 2D Tile Map setup

# Day 30
Tile map stuff is looking alright. Doing my best to not clean-up the code as Casey pleads in the vods.
I would have perferred if he didn't just do one tilemap at a time and instead I would have had the current tile map and surrounding loaded at the same time (He might do this in the future). Since were aren't constrained memory wise like the old machines, we could have those loaded as well and it would make the management of the tilemaps easier (possibly...).
Looking foward to when he introduces a proper vector space for the positioning.
