Character - Free View Camera

_aCe_Total · December 2, 2015, 8:51pm

Hi,

I must first say that c++ and Unreal Engine 4 is still pretty new to me. I tried to use the ‘Headattached Camera’ as an 180 degrees Free view Camera when pressing the ALT-key (Like Arma 2/3 Free view). But I’ve obviously done something very wrong, since I get a whole bunch of error messages and I have no idea how to fix this or lock the Camera Movement to 180 degrees. I’ll be very grateful if anyone can help me solve this.

The FreeView input mapping:


+ActionMappings=(ActionName="FreeView",Key=None,bShift=False,bCtrl=False,bAlt=True,bCmd=False)

In your cpp, some method implementations start with “TWGameCharacter” instead of “ATWGameCharacter”

Those are causing the compiler errors

Thank you, Fallonsnest! That was embarrassing :o

The Bind Action error was fixed with this:


InputComponent->BindAction("FreeView", IE_Pressed, this, &ATWGameCharacter::FreeViewStarted);
InputComponent->BindAction("FreeView", IE_Released, this, &ATWGameCharacter::FreeViewStopped);

and the ActionMapping was changed to:


-ActionMappings=(ActionName="FreeView",Key=LeftAlt,bShift=False,bCtrl=False,bAlt=False,bCmd=False)

I still have two questions I need help with:

How can I get the Freeview input to function while pressing the W-button to run? I want to be able to move the head with my mouse while the character runs in the same direction as before I pressed the ALT-key.
How to set a rotation limit on the Free view camera? I want that the rotation to stop at the line with the shoulder, so I can’t see directly backwards. Real life head movements.

each input has its own callback function that is not affected directly by other inputs. so if you want to run while looking around just use a if else and feed the rotation of looks to head bone and use that in your animation blueprint .

To limit the rotation either use a clamp or simply if else
