When i pressed A or D the camera turning, as if my camera is locked

You can press the middle mouse button (if you have not rebound it) and then you can move your mouse independently of your character movement

Well im not exactly searching to moove freely my camera, but instead not having my camera mooving when i moove my character..

Idk if its clear ahah, but i would if it possible, but i'm assuming its not, press a or d while sprinting and not have my camera mooving at all

No, other than the function i told you, there is no way to "strive" in BDO like in other games. Your camera will always turn with the character movement when sprinting

It is possible to fix your camera in whichever rotation you leave it at while your character is auto-walking (So your camera doesn't rotate behind your character) by turning off the setting as shown below.

But this does not work for actively walking with WASD. You can freely rotate the camera around your character while holding middle mousebutton as Mina described, but not the other way around.

A third option would be to use mouse click to move feature. This allows you to click on the world with your mouse and your character moves towards there. That way you can walk any direction while your camera remains facing the same way.

Sadge, thx for the reply, i think i will just spam the auto run
