I have a little C++ code to move my pawn depending on the acceleration.
FVector loc = GetActorLocation();
FVector currentSpeed = GetVelocity();
FVector acc = mode->gravity;
UE_LOG(LogTemp, Warning, TEXT("acceleration is %f, %f, %f"), acc.X, acc.Y, acc.Z);
FVector dist = deltaTime * currentSpeed + (deltaTime * deltaTime / 2.0) * acc;
UE_LOG(LogTemp, Warning, TEXT("distance is %f, %f, %f"), dist.X, dist.Y, dist.Z);
FVector newLoc = loc + dist;
UE_LOG(LogTemp, Warning, TEXT("new location is %f, %f, %f"), newLoc.X, newLoc.Y, newLoc.Z);
SetActorLocation(newLoc);
UE_LOG(LogTemp, Warning, TEXT("After setting new location"));
The actor doesnt seem to move at all. Infact the last two log lines also dont appear in the logs.
sample logs:
