[HELP] Simulating user fire.

Hello,
I have CNetObj_PlayerInput object and Its properly passed to OnPredictedInput();
The only thing I can't get is how to set the m_Fire value to fire weapon... 1 doesn't work... Rest like movement, aiming is ok, but Cant fire. I looked at my input when playing and m_Fire starts at 0 and on key press its incrased by 1 (so its unpairable (m_Fire%2==1)) and on release it increases too (So when not pressing its m_Fire%2==0), but It didnt helped. Any Ideas?

PS. Its server modification, dont ask how do I pass and what do I simulate just lemme know how to set m_Fire to fire actually.
