| Readme: In the following pseudo code, [] indicates a subroutine. | |
| Sometimes I choose to write the subroutine inline under the [] in order to maintain context. | |
| One important fact about the way rollbacks are handled here is that we are storing state for every frame. | |
| In any real implementation you only need to store one game state at a time. Storing a game | |
| state for every frame allows us to only rollback to the first frame where the predicted inputs don't match the true ones. | |
| ==Constants== | |
| MAX_ROLLBACK_FRAMES := Any Positive Integer # Specifies the maximum number of frames that can be resimulated | |
| FRAME_ADVANTAGE_LIMIT := Any Positive Integer # Specifies the number of frames the local client can progress ahead of the remote client before time synchronizing. |
Below are the steps to get an ARM64 version of Ubuntu running in the QEMU emulator on Windows 10.
Install for Windows from https://qemu.weilnetz.de/w64/ (I used qemu-w64-setup-20181211.exe)
Put C:\Program Files\qemu on your PATH, and run the below to check it's working (which will list out
the CPUs the AArch64 emulator can emulate):
qemu-system-aarch64 -M virt -cpu help
