If I'm using the "SetCameraRotationQuat(" command, the "RotateCameraLocal" commands are not working anymore after it.
Looks like it locks the camera on the rotational axis.
Any confirmation?

Example:

+ Code Snippet

CreateObjectBox(1,4.0,4.0,4.0)
textimg = CreateImageColor(0,255,255,255)
SetObjectImage(1,textimg,0)
RotateObjectLocalY(1,45.0)

CreateLightDirectional(1,-1.0,-0.5,-0.5,255,255,255)

key_down = 40
key_up = 38
key_left = 37
key_right = 39

rem SetCameraRotationQuat(1,0.0,0.0,0.0,0.0) // Delete "rem" to see the rotation lock problem

do
    if GetRawKeyState(key_down) = 1
		RotateCameraLocalX(1,0.2)
	endif
    if GetRawKeyState(key_up) = 1
		RotateCameraLocalX(1,-0.2)
	endif
	if GetRawKeyState(key_right) = 1
		RotateCameraLocalY(1,0.2)
	endif
    if GetRawKeyState(key_left) = 1
		RotateCameraLocalY(1,-0.2)
	endif
    Sync()
loop

"By default cameras are created with the quaternion 1,0,0,0 in the order w,x,y,z."

means cam id,1,0,0,0

u used 0,0,0,0 at w,x,y,z

+ Code Snippet

rem
rem AGK Application 1.08 19
rem MR

setdisplayaspect(320/480.0)
setvirtualresolution(320,480)
setclearcolor(0,0,125)

createlightdirectional(1,0,-1,1,255,255,255)

CreateObjectcone( 1, 3,3,3 )
setobjectcolor(1,125,125,0,255)
SetObjectposition( 1,0,0,5 )

setcameraposition(1,0,0,-5)
setcameralookat(1,0,0,5,0)

do

    //axis
    ax#=0.0
    ay#=1.0
    az#=0.0

    //angle in degree
    theta# = theta# + 1.0
    w#   =   cos(theta#)
    x#   =   ax# * sin(theta#)
    y#   =   ay# * sin(theta#)
    z#   =   az# * sin(theta#)

    SetObjectRotationQuat( 1, w#,x#,y#,z# )

    sync()
loop
