Function: createHoverChannel()
ts
function createHoverChannel(): HoverChannel;Builds a fresh HoverChannel. Each call returns an independent set of refs so a multi-body scene can give every body its own channel:
ts
const mars = useBody(marsConfig, tileSize) // channel auto-created
const venus = useBody(venusConfig, tileSize) // its own channel
<TileCenterProjector :channel="mars.hoverChannel" ... />
<TileCenterProjector :channel="venus.hoverChannel" ... />Callers that want a shared global slot (single popover UX, single tooltip in the HUD) build one channel up-front and pass it to every body via the hoverChannel option of useBody.
