Hi , Currently I'm planning the next level for Behind Enemy Lines. Since the player has to do part of the level with a sniper rifle, a little preliminary work had to be done. So, Here's my way to tackle this topic with the Addon "FPS Weapon Pack": The tutorial from tipforeveryone was very helpful to me. You can find it here https://www.leadwerks.com/community/blogs/entry/1775-realistic-sniper-rifle-scope-in-lua/ i downloaded a Scope frome here :http://www.cadnav.com/3d-models/model-36647.html and put it as a child to the "vwep m4" and saved it as a prefab "vwep m4_sniper" it should be look like this Now you have to ajust the scope But for the scope script to work, an empty script must be inserted in the following places. Thanks to Macklebee for this hint! Now you have to change 2 scripts 1. fpsgun.lua 2. fpsplayer.lua 1. fpsgun.lua this script i saved under "FPSGun_Sniper.lua" then this video helps a lot :https://www.youtube.com/watch?time_continue=628&v=3OqwQSP-2FU thanks to BluHornet place this in your fpsgun_sniper.lua Script.offsetNor=Vec3(0,0,0) Script.offsetADS=Vec3(0,0,0)--Vec3 "Offset ADS" the next line put after the function Script:Start() self.offsetNor = self.offset self.hasZoom=true self.hasZoom=true (or false) has been inserted because the ironsight will be active in every weapon, but at Grenade or something else i did not want this. Since I have difficulty with the sway of the weapon and I have no solution for it currently, I commented under function Script: Draw () the following lines out: --self.swayspeed = Math:Curve(speed,self.swayspeed,20) --self.swayspeed = math.max(0.5,self.swayspeed) --self.amplitude = math.max(2,Math:Curve(speed,self.amplitude,20)) now its time to change the fpsplayer.lua 2. fpsplayer.lua this line put in at the beginning Script.ADSmode=false next place the following lines under the function Script:UpdateWorld() if self.weapons[self.currentweaponindex]~=nil and self.weapons[self.currentweaponindex].hasZoom then if self.ADSmode == false then self.camera:SetFOV(70) self.weapons[self.currentweaponindex ].offset = self.weapons[self.currentweaponindex ].offsetNor end if self.ADSmode == true then self.camera:SetFOV(20) self.weapons[self.currentweaponindex ].offset = self.weapons[self.currentweaponindex ].offsetADS end end and this also in this function (i put this after a lince called "--fire weapon" if window:MouseHit(2) then if self.weapons[self.currentweaponindex]~= nil then if self.ADSmode == false then self.ADSmode=true else self.ADSmode=false end if self.sound.pickupweapon~=nil then self.sound.pickupweapon:Play() end end end if you do not want the ironsight by jump, reload, or carry an item, then paste those lines at the right places self.ADSmode=false Since the original crosshair disturbs me in the ironsight, I have inserted "and self.ADSmode==false then" in the function Script:PostRender(context) it should looks like this if self.health>0 then if self.canUse==true and self.carryingEntity == nil then local pickUpX = math.floor((context:GetWidth() - self.image.hand:GetWidth()))/2 local pickUpY = math.floor((context:GetHeight() - self.image.hand:GetHeight()))/2 context:SetBlendMode(Blend.Alpha) context:DrawImage(self.image.hand, pickUpX, pickUpY) else if self.carryingEntity==nil then if self.weapons[self.currentweaponindex]~=nil then if self.image.crosshair and self.ADSmode==false then local crossHairX = math.floor((context:GetWidth() - self.image.crosshair:GetWidth()))/2 local crossHairY = math.floor((context:GetHeight() - self.image.crosshair:GetHeight()))/2 context:SetBlendMode(Blend.Alpha) context:DrawImage(self.image.crosshair, crossHairX, crossHairY) end end end end What follows now are the individual settings for each weapon to get an Ironsight. M4 Sniper: in the script: the sniper M4 looks now like this the m4 without scope in the script: it should look like this the shotgun in the script the shotgun look like this the pistol in the script the pistol look now like this So, that was my solution. But if you have even better settings, feel free to write in this blog. I hope that this blog helped a bit. Especially to save time to find the settings for the Ironsight. Have fun. Greetings burgelkat
