Struct RespawnSystem 

pub struct RespawnSystem {
    pub last_checkpoint: Option<u64>,
    pub respawn_count: u32,
    pub activation_radius: f32,
    /* private fields */
}

Tracks the active checkpoint and handles player respawning.

Call update_checkpoint periodically (e.g. when the player enters a checkpoint trigger zone) to register the nearest checkpoint as active. Call respawn on player death to retrieve the saved state.

Fields

last_checkpoint: Option<u64>

The id of the last activated checkpoint, if any.

respawn_count: u32

How many times the player has respawned.

activation_radius: f32

The minimum distance from a checkpoint to auto-activate it.

Implementations

impl RespawnSystem

pub fn new() -> Self

Create a new respawn system with no active checkpoint.

pub fn with_activation_radius(self, r: f32) -> Self

pub fn update_checkpoint( &mut self, manager: &CheckpointManager, player_pos: Vec2, ) -> Option<u64>

Update the active checkpoint based on the player’s current position.

If the player is within activation_radius of any checkpoint, the nearest one becomes the active checkpoint. Returns the id of the newly activated checkpoint (if one was activated this call) or None.

pub fn activate(&mut self, checkpoint_id: u64)

Manually activate a checkpoint by id.

pub fn deactivate(&mut self)

Clear the active checkpoint (e.g. at the start of a level).

pub fn respawn<'a>( &mut self, manager: &'a CheckpointManager, game_time: f64, ) -> Option<&'a WorldSnapshot>

Get the snapshot to restore on respawn.

Returns None if no checkpoint has been activated.

pub fn peek_snapshot<'a>( &self, manager: &'a CheckpointManager, ) -> Option<&'a WorldSnapshot>

Get the snapshot without incrementing the respawn counter.

pub fn has_checkpoint(&self) -> bool

pub fn respawn_history(&self) -> &[RespawnEvent]

pub fn clear_history(&mut self)

pub fn checkpoint_position(&self, manager: &CheckpointManager) -> Option<Vec2>

The position of the active checkpoint, if any.

Trait Implementations

impl Default for RespawnSystem

fn default() -> Self

Returns the “default value” for a type.
