Variables

  Type Name Description
Public variable UProperty Category, EditAnywhere, AdvancedDisplay BlueprintReadWrite TArray< TObjectPtr< AActor > > ActorsToIgnore Actors to ignore when tracing with collision.
Public variable UProperty Category, EditAnywhere, AdvancedDisplay BlueprintReadWrite bool bTraceComplex Trace against complex collision (triangles rather than simple primitives) if tracing with collision.
Public variable UProperty Category, EditAnywhere BlueprintReadWrite bool bTraceWithChannel Whether or not to use TraceChannel, if tracing with collision.
Public variable UProperty Category, EditAnywhere BlueprintReadWrite bool bTraceWithCollision Whether to trace along the path looking for blocking collision and stopping at the first hit.
Public variable UProperty Category, EditAnywhere, AdvancedDisplay BlueprintReadWrite float DrawDebugTime Duration of debug lines (only relevant for DrawDebugType::Duration)
Public variable UProperty Category, EditAnywhere, AdvancedDisplay BlueprintReadWrite TEnumAsByte< EDrawDebugTrace::Type > DrawDebugType Debug drawing duration option.
Public variable UProperty Category, EditAnywhere BlueprintReadWrite FVector LaunchVelocity Initial launch velocity at the start of the trace.
Public variable UProperty Category, EditAnywhere BlueprintReadWrite float MaxSimTime Maximum simulation time for the virtual projectile.
Public variable UProperty Category, EditAnywhere, AdvancedDisplay BlueprintReadWrite TArray< TEnumAsByte< EObjectTypeQuery > > ObjectTypes Object type to use, if tracing with collision.
Public variable UProperty Category, EditAnywhere, AdvancedDisplay BlueprintReadWrite float OverrideGravityZ Optional override of Gravity (if 0, uses WorldGravityZ).
Public variable UProperty Category, EditAnywhere BlueprintReadWrite float ProjectileRadius Projectile radius, used when tracing for collision. If <= 0, a line trace is used instead.
Public variable UProperty Category, EditAnywhere, AdvancedDisplay BlueprintReadWrite 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.
Public variable UProperty Category, EditAnywhere BlueprintReadWrite FVector StartLocation Location of the start of the trace.
Public variable UProperty Category, EditAnywhere BlueprintReadWrite TEnumAsByte< ECollisionChannel > TraceChannel Trace channel to use, if tracing with collision.

Constructors

  Type Name Description
Public function   Empty constructor. You typically want to use another one that enforces thought about reasonable values for the most important parameters.
Public function  

FPredictProjectilePathParams ( float InProjectileRadius,
FVector InStartLocation,
FVector InLaunchVelocity,
float InMaxSimTime
)

 Constructor defaulting to no collision.
Public function  

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.
Public function  

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.
