struct FPredictProjectilePathParams

Input parameters to PredictProjectilePath functions.

Type	Name	Description
TArray< TObjectPtr< AActor > >	ActorsToIgnore	Actors to ignore when tracing with collision.
bool	bTraceComplex	Trace against complex collision (triangles rather than simple primitives) if tracing with collision.
bool	bTraceWithChannel	Whether or not to use TraceChannel, if tracing with collision.
bool	bTraceWithCollision	Whether to trace along the path looking for blocking collision and stopping at the first hit.
float	DrawDebugTime	Duration of debug lines (only relevant for DrawDebugType::Duration)
TEnumAsByte< EDrawDebugTrace::Type >	DrawDebugType	Debug drawing duration option.
FVector	LaunchVelocity	Initial launch velocity at the start of the trace.
float	MaxSimTime	Maximum simulation time for the virtual projectile.
TArray< TEnumAsByte< EObjectTypeQuery > >	ObjectTypes	Object type to use, if tracing with collision.
float	OverrideGravityZ	Optional override of Gravity (if 0, uses WorldGravityZ).
float	ProjectileRadius	Projectile radius, used when tracing for collision. If <= 0, a line trace is used instead.
float	SimFrequency	Determines size of each sub-step in the simulation (chopping up MaxSimTime). Recommended between 10 to 30 depending on desired quality versus performance.
FVector	StartLocation	Location of the start of the trace.
TEnumAsByte< ECollisionChannel >	TraceChannel	Trace channel to use, if tracing with collision.

	Type	Name	Description
		FPredictProjectilePathParams ()	Empty constructor. You typically want to use another one that enforces thought about reasonable values for the most important parameters.
		FPredictProjectilePathParams ( float InProjectileRadius, FVector InStartLocation, FVector InLaunchVelocity, float InMaxSimTime )	Constructor defaulting to no collision.
		FPredictProjectilePathParams ( float InProjectileRadius, FVector InStartLocation, FVector InLaunchVelocity, float InMaxSimTime, EObjectTypeQuery ObjectType, AActor* ActorToIgnore )	Constructor to use collision with an ObjectType. Additional types can be added to the array. TraceWithCollision is set to true automatically.
		FPredictProjectilePathParams ( float InProjectileRadius, FVector InStartLocation, FVector InLaunchVelocity, float InMaxSimTime, ECollisionChannel InTraceChannel, AActor* ActorToIgnore )	Constructor to use collision with a trace channel. TraceWithCollision is set to true automatically.
