Detailed Description

A traffic sign baked into a level from the regional sign catalog: a pole and a plate whose material is a constant instance of the atlas selector with the cell baked in.

Being an ATrafficSignBase, ATrafficLightManager::SpawnSignals adopts it for the OpenDRIVE signal it stands at (within 5 m, TrafficSignState agreeing with the signal type/subtype) and attaches the matching USignComponent, so the map gets the regional look without a duplicate stock blueprint at the same spot.

◆ ConfigureForSignal()

void AGeoTrafficSign::ConfigureForSignal	(	const FString &	Type,
		const FString &	Subtype
	)

Set XodrType / XodrSubtype and the matching runtime state (speed limit in km/h from the subtype) so ATrafficLightManager adopts this actor for the signal.

◆ PostInitializeComponents()

void AGeoTrafficSign::PostInitializeComponents ( )

overridevirtual

Levels baked before every km/h value had a state carry UNKNOWN for e.g.

10 km/h signs; derive the state from XodrType / XodrSubtype so they are adopted without a rebake.

Definition at line 55 of file GeoTrafficSign.cpp.

References ConfigureForSignal(), ATrafficSignBase::GetTrafficSignState(), UNKNOWN, XodrSubtype, and XodrType.

◆ Setup()

void AGeoTrafficSign::Setup	(	UStaticMesh *	PoleMesh,
		UStaticMesh *	PlateMesh,
		UMaterialInterface *	PlateMaterial,
		FVector	PlateOffset,
		float	PlateYaw,
		float	PlateScale
	)

Assign meshes / material and place the plate.

PlateOffset is relative to the actor (the pole base), in cm; PlateYaw in degrees turns the plate on the pole.

The ETrafficSignState the traffic-light manager matches against for an OpenDRIVE signal type/subtype: stop, yield, or the speed-limit state for the subtype (km/h; ETrafficSignState::SpeedLimit for values without a dedicated state — then also call SetSpeedLimitKmh, or use ConfigureForSignal).
