Vive Teleporter in C++ : Part 2

Vive Teleporter in C++ : Part 2

Mapping controller buttons into code went very well.

Now onto the teleport arc. Here is the code in blueprint:

Everything is flowing in and out of that big blue-header box.

I found the method:
UGameplayStatics::Blueprint_PredictProjectilePath_ByObjectType

That thing takes in 16 parameters!

Who the hell names a method Blueprint_ ?

Fortunately we can see all of them on the screen but 1. Some of the parameters are output parameters. I actually have my code calling this method on teleport button press and getting 60 points back that appear to be along an arc. Now I just need to build a spline based on these points.

Since nobody on the planet seems to be calling this method from C++, let me help you:

UObject* WorldContextObject = GetWorld();

Location = RightMotionController->GetComponentLocation(); ForwardVector = RightMotionController->GetForwardVector();

// INPUT --------------------------
FVector StartPos = Location;
float Velocity = 900.0f;
FVector LaunchVelocity = UKismetMathLibrary::Multiply_VectorFloat(ForwardVector, Velocity);
bool bTracePath = true;
float ProjectileRadius = 0.0f;
TArray<TEnumAsByte<EObjectTypeQuery>> ObjectTypes;
ObjectTypes.Add(EObjectTypeQuery::ObjectTypeQuery1);
bool bTraceComplex = false;
const TArray<AActor*> ActorsToIgnore;
EDrawDebugTrace::Type DrawDebugType = EDrawDebugTrace::None;
float DrawDebugTime = 0.0;
float SimFrequency = 30.0;
float MaxSimTime = 2.0;
float OverrideGravityZ = 0.0;

// OUTPUT --------------------------
FHitResult OutHit;
TArray<FVector> OutPathPositions;
FVector OutLastTraceDestination;

bool HitSomething = UGameplayStatics::Blueprint_PredictProjectilePath_ByObjectType(
WorldContextObject,
OutHit,
OutPathPositions,
OutLastTraceDestination,
StartPos,
LaunchVelocity,
bTracePath,
ProjectileRadius,
ObjectTypes,
bTraceComplex,
ActorsToIgnore,
DrawDebugType,
DrawDebugTime,
SimFrequency,
MaxSimTime,
OverrideGravityZ
);
