Scheduler

Defined in: src/scheduler.ts:167

The starting point of a game made with Toucan.

Methods

run()

run(): this

Defined in: src/scheduler.ts:230

Synchronously builds all initially registered plugins (user-defined first), and then bootstraps the engine to run all systems on their respective phases.

Systems and plugins scheduled dynamically after the scheduler is already running will be picked up automatically on the next frame (with the exception of the STARTUP phase, which only fires once during this method call).

Returns

this

usePlugin()

usePlugin<Args>(plugin, …args): this

Defined in: src/scheduler.ts:217

Schedules a plugin to be built, passing it the scheduler itself and the provided arguments.

Reflection

Plugins are entities with the standard Plugin component, thus, they can be queried and manipulated like any other entity in Toucan.

Plugins scheduled within other plugins are automatically parented to the parent plugin.

Type Parameters

Args

Args extends defined[]

Parameters

plugin

Plugin<Args>

args

…Args

Returns

this

Example

function updatePhysics(gravity: number) { ... }

function physicsPlugin(scheduler: Scheduler, gravity: number) {
    scheduler.useSystem(updatePhysics, UPDATE, gravity)
}

scheduler()
   .usePlugin(physicsPlugin, 196.2)
   .run()

useSystem()

useSystem<Args>(system, phase, args?, label?): this

Defined in: src/scheduler.ts:187

Schedules a system to run in the specified phase with the provided arguments.

Reflection

Systems are entities with the standard System component, thus, they can be queried and manipulated like any other entity in Toucan.

Systems scheduled within plugins are automatically parented to the plugin.

Type Parameters

Args

Args extends defined[]

Parameters

system

System<Args>

phase

Phase

args?

Args

label?

string

Returns

this

Example

function fireGun(params: RaycastParams) { ... }

scheduler()
    .addSystems(UPDATE, [fireGun], new RaycastParams())
    .run()
