The nearest ancestor <pc-app> element, or null if this element has no <pc-app>
ancestor. The search starts at the parent, so an element never resolves to itself.
The closest app element, or null.
The nearest ancestor element that fronts an entity — <pc-entity>, <pc-model> or
<pc-node> — or null if this element has no such ancestor. The search starts at the
parent, so an element never resolves to itself.
The closest entity-fronting element, or null.
Protected_Called when the element is fully initialized and ready. Subclasses should call this when
they're ready. Resolves the ready promise and dispatches a bubbling, composed ready
event. Signals at most once per readiness cycle: a repeat call before _resetReady
has re-armed the promise does nothing.
Protected_Returns the ready promise to its pending state. Subclasses should call this when the
resource their readiness announced is torn down (typically from disconnectedCallback),
so that a later re-initialization can signal readiness again. Does nothing while the
promise is still pending — an in-flight waiter carries over to the next readiness cycle
rather than being stranded on a promise nothing will ever resolve.
Returns a promise that resolves with this element when it's ready. This is the low-level primitive underlying whenReady, which is the recommended way to wait for elements.
Readiness tracks the element's current lifecycle: once a ready element is torn down (for example by removing it from the document), this returns a fresh promise that resolves when the element is next ready. A promise obtained earlier stays resolved — call this again after re-inserting an element rather than reusing a promise from before its removal.
A promise that resolves with this element when it's ready.
The WasmElement interface provides properties and methods for manipulating
<pc-wasm>elements. The WasmElement interface also inherits the properties and methods of the AsyncElement interface.The attributes are read once, when the module starts loading - on the element's first connection, or earlier if a containing
<pc-app>boots first and collects it - so changing them later has no effect. The element becomes ready once the module has loaded. WebAssembly modules configure engine-global state that never unloads, so readiness is not re-armed by removing the element, and a re-inserted element does not load again.A
<pc-wasm>without anamewarns and never becomes ready; a containing<pc-app>still boots.Attribute
name - The name of the WebAssembly module to configure, e.g.
BasisorAmmo.Attribute
glue - The URL of the module's glue script.
Attribute
wasm - The URL of the module's WebAssembly binary.
Attribute
fallback - The URL of the module's asm.js fallback script, used when WebAssembly is unavailable.
