How do I make an object transparent?

[Andrew75t]

I have a script-chec

k, if the player has a sniper rifle in his hands and he is aiming, then a message is displayed in the chat.
In the sight I see the model of the object (id 321) that I replaced and attached using bone_attach. I want it to become transparent in aiming mode. How do I apply setElementAlpha to this object?

I made a transparent texture for the default rifle (id 34). And with the help of bone_attach, I attached the object (id 321), which I replaced with the new SVD model. When I am in aiming mode I see the SVD model, I need to make it transparent (invisible)

Client side:

function aimAction (key, state)
    if (getPedWeapon (localPlayer) ~= 34) then return end
	
    outputChatBox ("You are aiming now", 255, 0, 0)                  
    for control in pairs (getBoundControls(key)) do
        setPedControlState (control, false)
    end
end
bindKey ("mouse2", "down", aimAction)

Server side:

function attachSVD (thePlayer)
    local x, y, z = getElementPosition (thePlayer)
    local objPick = createObject (321, x, y, z)
    setTimer (function (thePlayer)
	giveWeapon ( thePlayer, 34, 200, true )
        exports.bone_attach:attachElementToBone (objPick, thePlayer, 12, 0, 0, 0, 0, -90, 0)
    end, 1000, 1, thePlayer)
end
addCommandHandler ("svd", attachSVD)

Repale models:

function replaceWeapon() -- Invisible defolt sniper riflle
txd = engineLoadTXD ( "mdls/weapons/sniper_rifle/sniper.txd" )
engineImportTXD ( txd, 358)
-- SVD model --
txd = engineLoadTXD ( "mdls/weapons/sniper_rifle/svd.txd" )
engineImportTXD ( txd, 321)
dff = engineLoadDFF ( "mdls/weapons/sniper_rifle/svd.dff")
engineReplaceModel ( dff, 321) 
end
addEventHandler ( "onClientResourceStart", resourceRoot, replaceWeapon)

you could store the attached weapon object in an element data (setElementData)

then retrieve this element data client-sidely (getElementData) once the player is aiming and hiding the object with setElementAlpha

 

OR 

 

you could not use element datas (cause it has a lot of security issues and lacks of performance) and send the object manually to client side (triggerClientEvent)

You can get the weapon element using getAttachedElements(player) and filtering the result, then set alpha to 0.

GetAttachedElements doesn't work with the bone_attach resource since the attached objects aren't attached with attachElements
