Struct ggrs::SyncTestSession

pub struct SyncTestSession { /* fields omitted */ }

During a SyncTestSession, GGRS will simulate a rollback every frame and resimulate the last n states, where n is the given check distance. The resimulated checksums will be compared with the original checksums and report if there was a mismatch.

Implementations

impl SyncTestSession

pub fn advance_frame(
    &mut self,
    player_handle: PlayerHandle,
    input: &[u8]
) -> Result<Vec<GGRSRequest>, GGRSError>

In a sync test, this will advance the state by a single frame and afterwards rollback check_distance amount of frames, resimulate and compare checksums with the original states. Returns an order-sensitive Vec<GGRSRequest>. You should fulfill all requests in the exact order they are provided. Failure to do so will cause panics later.

Errors

• Returns InvalidHandle if the provided player handle is higher than the number of players.
• Returns MismatchedChecksumError if checksums don’t match after resimulation.

pub fn set_frame_delay(
    &mut self,
    frame_delay: u32,
    player_handle: PlayerHandle
) -> Result<(), GGRSError>

Change the amount of frames GGRS will delay the inputs for a player.

Errors

Returns InvalidHandle if the provided player handle is higher than the number of players. Returns InvalidRequest if the provided player handle refers to a remote player.
