This is a simple improvement for the UAISense_Prediction I always add to any project I use it in. All it does it
throw a line trace between predicted actor and its predicted location, so that the sense doesn't predict it behind
or inside a wall.
Clone the repository in your project's Plugin directory.
FVector UAISense_PredictionPlus::GetPredictionLocation(const FAIPredictionEvent& Event) const
{
const FVector TargetLocation = Event.PredictedActor->GetActorLocation();
const FVector TargetVelocity = Event.PredictedActor->GetVelocity();
const FVector Displacement = TargetVelocity * Event.TimeToPredict;
const FVector DefaultPredictLocation = TargetLocation + Displacement;
const UWorld* World = GetWorld();
FCollisionQueryParams QueryParams;
QueryParams.AddIgnoredActor(Event.PredictedActor);
FHitResult Hit;
World->LineTraceSingleByChannel(Hit, TargetLocation, DefaultPredictLocation, CollisionChannel, QueryParams);
if (!Hit.bBlockingHit)
{
return DefaultPredictLocation;
}
// Don't predict if anything is on the way
const FVector ScaledNormal = Hit.ImpactNormal * BounceOffWall;
const FVector PredictLocation = Hit.Location + ScaledNormal;
return PredictLocation;
}
