I'm working on a SWEP and I have some questions.

[RussianLad]

Is there any way to cancel firing while drawing the weapon? I'm trying to make it work by adding a timer to the SWEP:Deploy function that makes fire primary return false during half a second or so but it doesn't work.

Is there any way to draw a crosshair when you press right click?

And the gun muzzle flash is not showing, what could be the problem?

(BTW I'm using the default SWEP base)

SWEP:DrawHUD ....

// TAKEN FROM CS BASE
if(self.Owner:KeyDown(IN_ATTACK2) then // I JUST ONLY ADDED THAT CONDITION MAN
surface.SetDrawColor( 0, 255, 0, 255 )

    // Draw an awesome crosshair
    local gap = 40 * scale
    local length = gap + 20 * scale
    surface.DrawLine( x - length, y, x - gap, y )
    surface.DrawLine( x + length, y, x + gap, y )
    surface.DrawLine( x, y - length, x, y - gap )
    surface.DrawLine( x, y + length, x, y + gap )

end

This is for crosshair. CUSTOM CROSSHAIR. If you want disable/enable default crosshair use self.DrawCrosshair variable

Recoil:

// Punch the crosshair
        if ( (game.SinglePlayer() && SERVER) || ( !game.SinglePlayer() && CLIENT && IsFirstTimePredicted() ) ) then

        local eyeang = self.Owner:EyeAngles()    else
        eyeang.pitch = eyeang.pitch - self.Primary.RecoilX // just add these two variables.. try with some values
        eyeang.yaw = eyeang.yaw - self.Primary.RecoilY // JUST COPIED FROM MY SWEP and you have something to learn
        end

        self.Owner:SetEyeAngles( eyeang )

    end

For rest of your questions find on forum, there are answers. For muzzle flash find for "custom muzzle flash swep" or something similiar. You will find the right answer.
For canceling primary attack just add in deploy function:     self:SetNextPrimaryFire(CurTime() + any number here)
