Third Person: Why Do Characters Stop When Camera Facing Straight Down?

Dear Friends at Epic,

What is this new odd behavior in most recent version of the Engine?

In third Person games, if the camera is facing straight down, the character can only move in the A and D key directions.

W and S do not cause character to move!

This never used to happen before, in the Beta or even earliest UE4 versions.

How do I fix this?

Where is this code occurring?

How come A and D keys work, but not W and S


Start a new third person C++ project

go in game in PIE

aim the camera straight down

try to move in W and S directions

then try and move in A and D directions

I can only get character to move in A and D when I do this


I got around this issue by writing this code:

void AVictoryPlayerCharacterBase::MoveForward(float Value)
	//Has the strange behavior of 
	if ((Controller != NULL) && (Value != 0.0f))
		// find out which way is forward
		const FRotator Rotation = Controller->GetControlRotation();
		const FRotator YawRotation(0, Rotation.Yaw, 0);

		// get forward vector
		const FVector Direction = FRotationMatrix(Rotation).GetUnitAxis(EAxis::X);
		AddMovementInput(Direction, Value);

	if ((Controller != NULL) && (Value != 0.0f))
		const FRotator YawRotation(0, Controller->GetControlRotation().Yaw, 0);
		AddMovementInput(YawRotation.Vector(), Value);

The commented out code is what comes with the starter 3rd person project

Result: Character now continues to move in all 4 key directions WASD, even when camera is facing straight down or up. Character movement never slows just because of camera pitch angle

#Needs to be Addressed

I think this needs to be addressed, as it feels like a bug that the player is only stopped from moving in W and S directions when camera is straight down, but can still move in A and D

Hi ,

Thank you for letting us know about this movement behavior. Another user notified us of this issue a little while ago. We have already implemented a fix internally, and the movement behavior that you described will be corrected in a future version of the Engine.



Sorry I missed your reply !

Thanks for the update!
