Trace while in air

Development Programming & Scripting

I am doing a ledge grab exactly like in crysis 3 where when in air it will perform a raycast an if there is a ledge grab entity or a spline in my case it will say something for now. Right now here is my source.
FHitResult Hit;
FVector Start, End;
float Radius = 100;

	Start = GetActorLocation() + FVector(0, 0, 50);
	End = Start + (GetActorRotation().Vector() * 100);

	FCollisionQueryParams Params(TEXT("Trace"), false, this);
	FCollisionObjectQueryParams ObjectParams;
	GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Yellow, TEXT("This is an on screen message!"));
	if (GetWorld()->LineTraceSingle(Hit, Start, End, Params, ObjectParams))
	{
		GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::White, TEXT("This is an on screen message!"));
	}

this is in my on start jump function. What it does right now is everytime it hit space bar it does a trace but thtas not what i want i want it to perform a trace while in the air. I tried a while loop in my tick function and tried it such that if bPressedJump is true it will perform the trace and so on but when i try that it crashes. Some help please?

You can check the character velocity Z value if it not 0 then he in the air, > 0 is jump up, < 0 falling down.
