Struct game::app::PerMap

pub struct PerMap {

    pub map: Map,
    pub draw_map: DrawMap,
    pub sim: Sim,
    pub agents: RefCell<AgentCache>,
    pub current_selection: Option<ID>,
    pub current_flags: Flags,
    pub last_warped_from: Option<(Pt2D, f64)>,
    pub sim_cb: Option<Box<dyn SimCallback>>,
    pub dirty_from_edits: bool,
    pub has_modified_trips: bool,
    pub unedited_map: Option<Map>,
    pub layer: Option<Box<dyn Layer>>,
    pub suspended_sim: Option<Sim>,
    prebaked: Option<(MapName, String, Analytics)>,
    pub scenario: Option<Scenario>,
    pub is_secondary: bool,
}

All of the state that’s bound to a specific map.

Fields

map: Map

draw_map: DrawMap

sim: Sim

agents: RefCell<AgentCache>

current_selection: Option<ID>

current_flags: Flags

last_warped_from: Option<(Pt2D, f64)>

sim_cb: Option<Box<dyn SimCallback>>

dirty_from_edits: bool

If we ever left edit mode and resumed without restarting from midnight, this is true.

has_modified_trips: bool

Any ScenarioModifiers in effect?

unedited_map: Option<Map>

If the map has been edited and app.store_unedited_map_in_secondary is false, store the unedited map here.

layer: Option<Box<dyn Layer>>

suspended_sim: Option<Sim>

Only filled out in edit mode. Stored here once to avoid lots of clones. Used for preview.

prebaked: Option<(MapName, String, Analytics)>

Only exists in some gameplay modes. Must be carefully reset otherwise. Has the map and scenario name too.

scenario: Option<Scenario>

The most recent Scenario loaded from a file. Don’t depend on it always matching the current gameplay mode; always verify the name matches what’s needed.

Storing this may cost some memory, but otherwise resetting to midnight would require loading it again from a file. This is particularly painful on the web!

is_secondary: bool

Is this the original “secondary” state, loaded via –diff?
