Component

component declares an ECS component: a plain-old-data (POD) storage unit with fields and no behavior, read and written by a query that filters entities by type.

Component data lives in the host’s native storage. No “component value” exists on the script side; a component shows up only in a query’s variable view.

Declaration Form

Declared at module top level, with two visibility tiers, public / internal:

module EcsDemo;
 
public component Position
{
    public var X: float;
    public var Y: float;
}
 
public component Velocity
{
    public var X: float = 0.0;
}
 
public component Enemy;
