Struct SpawnRequest 

pub struct SpawnRequest {
    pub template: AssetId,
    pub name: Option<AssetId>,
    pub transform: Transform,
    pub lifetime_secs: Option<f32>,
}

Runtime-only event requesting that a copy of an existing placement be created in the world at runtime. The symmetric counterpart to DespawnRequest.

template names a placement already present in the world; the new instance reuses that placement’s geometry and material at a fresh transform. A name registers the instance so it can later be addressed (despawned, reparented) like any authored placement; None spawns a transient copy, like a Spawner’s cadence spawns. An optional lifetime_secs attaches a Lifetime so the instance auto-despawns after that many seconds, the churn that lets freed draw slots be recycled. GraphicsSystem reads these from its Events<SpawnRequest> queue each step. World authors never declare this type directly.

Fields

template: AssetId

The placement to copy geometry and material from.

name: Option<AssetId>

Name to register the instance under, or None for a transient copy.

transform: Transform

Where to place the new instance.

lifetime_secs: Option<f32>

Seconds before the instance auto-despawns, when set.
