Hey! I am trying to create a script to allow me to check if the surface that the player has collided with is a wall, so that they can wall jump. Here is what I thought about doing:

```
//Get Collision Info
void AFPSCharacter::OnHit(AActor* OtherActor, UPrimitiveComponent* OtherComp, FVector NormalImpulse, const FHitResult& Hit)
{
	if (Hit.Rotation > wJumpSteepness && CharacterMovement->IsMovingOnGround())
	{
		canWallJump = true;
	}
}

```

With Hit.Rotation replacing the steepness of the surface. Is this possible? If someone could help me with this, it would be much appreciated! Thank you in advance.

#ImpactNormal

What you want is

```
Hit.ImpactNormal

```

This is the Vector representing the facing direction of the surface at the point of impact, in world space

to get this as a rotation:

```
const FRotator SurfaceRotation = Hit.ImpactNormal.Rotation();

```

Just know this is in world space and you can decide what qualifies as a sufficient angle for wall jumping

for example

if you wanted all walls to be at elast 70 degrees from the flat ground plan (almost totally vertical)

you would do

```
const FRotator SurfaceRotation = Hit.ImpactNormal.Rotation();
if(FMath::Abs(SurfaceRotation.Pitch) > 70)
{
  //yes this is a wall jump
}

```

to make sure you are getting the numbers you expect

make sure to LOG or output this value so you can see it exactly

```
const FRotator SurfaceRotation = Hit.ImpactNormal.Rotation();

```

Thank you very much (this is somewhat how it works in Unity as well)!
