Enumeration Type Documentation

EAsyncTraceType

enum class EAsyncTraceType : uint8

strong

Enum to indicate type of test to perfom

Enumerator
Test	Return whether the trace succeeds or fails (using bBlockingHit flag on FHitResult), but gives no info about what you hit or where. Good for fast occlusion tests.
Single	Returns a single blocking hit
Multi	Returns a single blocking hit, plus any overlapping hits up to that point

Function Documentation

DECLARE_DELEGATE_TwoParams() [1/2]

DECLARE_DELEGATE_TwoParams	(	FOverlapDelegate	,
		const FTraceHandle &	,
		FOverlapDatum &
	)

This is Overlap Delegate that can be used if you'd like to get notified whenever available Otherwise, you'll have to query manually using your TraceHandle

Parameters

FTHandle	TraceHandle that is returned when requestsed
FOverlapDatum	OverlapDatum that includes input/output

DECLARE_DELEGATE_TwoParams() [2/2]

DECLARE_DELEGATE_TwoParams	(	FTraceDelegate	,
		const FTraceHandle &	,
		FTraceDatum &
	)

This is Trace/Sweep Delegate that can be used if you'd like to get notified whenever available Otherwise, you'll have to query manually using your TraceHandle

Parameters

FTraceHandle	TraceHandle that is returned when requested
FTraceDatum	TraceDatum that includes input/output

DECLARE_LOG_CATEGORY_EXTERN()

ENGINE_API DECLARE_LOG_CATEGORY_EXTERN	(	LogCollision	,
		Warning	,
		All
