## Milestone
Day 39 : Basic Bitmap Rendering Cleanup
Day 40 : Cursor Hiding and Fullscreen Support
Features Done so far:
@ -44,14 +44,17 @@ Features Done so far:
* 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:
* Block Memory allocation via VirtualAlloc for engine module
* Memory mapped files for engine & game snapshots.
* Instantaneous hot reload of engine module
* Software rendering via Win32 GDI
* 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.
* Fullscreen toggle
* Can't change refresh rate
* Auto-hide cursor in client region (painted surface), not using editor tools
* 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.
