error C4430: missing type specifier - int assumed. Note: C++ does not
support default-int

i don't know what or how to solve this but it states :
'virtual' is not allowed
here is my code :
virtual CharacterPoseType; getPose();
virtual fCharacterPoseType; getChangingToPose();
virtual SoldierEntityActionState; actionState();
and there is the error it gives me
error C4430: missing type specifier - int assumed. Note: C++ does not
support default-int
any idea ?
