[HELP]attachElements question

[Chrimam]

How can i attach something to a ped's/player's weapon? I tried to attach a marker to a weapon so that wherever you aim, the marker will go there. I tried aimX, aimY, aimZ = getPedWeaponMuzzlePosition(getLocalPlayer()) but i think i made it wrong. and i don't know how to attach something to coordinates/weapon's muzzle position. Can you help me?

function myWeaponMarker(weapon) 
    if weapon == 24 then 
                playerX, playerY, playerZ = getElementPosition(getLocalPlayer()) 
                muzX, muzY, muzZ = getPedWeaponMuzzlePosition(getLocalPlayer()) 
                   weaponMarker = createMarker(playerX, playerY, playerZ, "corona", 0.5, 255, 0, 0, 170) 
///this is where the attaching script will go. 
end              
end 
addEventHandler("onClientPlayerTarget", getRootElement(), myWeaponMarker)

This is not compatible with all elements. The following elements are compatible:

Markers

Blips

Objects

Players

Vehicles

Sounds

Colshapes

this means you can't attach a marker to weapon.

[Chrimam]

so what do you suggest? I tried getPedTarget but it doesn't work properly.

hmm this event will be handled when you face a player or aim him

addEventHandler ( "onPlayerTarget",root, 
function (target) 
if getElementType (target) == "player" then -- if target is a player then 
local playerX, playerY, playerZ = getElementPosition(target) -- get his position 
weaponMarker = createMarker(playerX, playerY, playerZ, "corona", 0.5, 255, 0, 0, 170) -- create marker in his position 
attachElements(weaponMarker,target) -- attach the marker to the target 
end 
end) 

and this will be handled if you clicked the right button of mouse and checks the element etc..

addEventHandler("onPlayerClick",root, 
function (b,s) 
if p == "right" and s == "down" then -- if clicked button was right and buttons state is down then 
if  getElementType (getPedTarget(source)) == "player" then -- if target is a player then 
local playerX, playerY, playerZ = getElementPosition(getPedTarget (source)) -- get his position 
weaponMarker = createMarker(playerX, playerY, playerZ, "corona", 0.5, 255, 0, 0, 170) -- create a marker in his position 
attachElements(weaponMarker,getPedTarget (source)) -- attach the marker to the target 
end 
end 
end) 

i hope this will help you

i've wrote it quickly, forgive me if there's mistake in it

[Chrimam]

I don't want the marker to be attached to target. I want to attach the target in front of the weapon's muzzle position. and i think it's impossible for now.

Possible with setElementPosition + onClientPreRender.

[Chrimam]

I don't get any errors but "badArgument @ destroyObject" which works fine for me. But anyways, I can't attach my marker to weapon (i mean set the marker's position everytime frame changes)

function powerTeleport(weapon, ammo, ammoInClip, hitX, hitY, hitZ, hitElement) 
    if weapon == 24 then 
        playerX, playerY, playerZ = getElementPosition(getLocalPlayer()) 
            rotX, rotY, rotZ = getElementRotation(getLocalPlayer()) 
                teleportObject = createObject(1337, playerX, playerY, playerZ) 
                    setElementCollisionsEnabled(teleportObject, false) 
                        setElementAlpha(teleportObject, 0) 
                            attachElements(getLocalPlayer(), teleportObject, 0, 0, 0, 0, 0, 0) 
                                moveObject( teleportObject, 1000, hitX, hitY, hitZ, rotX, rotY, rotZ ) 
                                    setTimer(destroyTeleportObject, 1100, 1) 
    end 
end 
addEventHandler("onClientPlayerWeaponFire", getLocalPlayer(), powerTeleport) 
  
function destroyTeleportObject(teleportObject) 
    detachElements(getLocalPlayer(), teleportObject) 
        destroyElement(teleportObject) 
end 
  
  
function powerTeleportMarker(weapon, playerX, playerY, playerZ) 
    if weapon == 24 then 
        muzX, muzY, muzZ = getPedWeaponMuzzlePosition(getLocalPlayer()) 
            teleportMarker = createMarker(0, 0, 10, "corona", 1, 255, 0, 0, 170) 
                setElementPosition(teleportMarker, playerX, playerY, playerZ) 
                    addEventHandler("onClientPreRender", getRootElement(), 
function(teleportMarker, muzX, muzY, muzZ) 
setElementPosition(teleportMarker, muzX, muzY, muzZ) 
end) 
    end 
end 
addEventHandler("onClientPlayerTarget", getRootElement(), powerTeleportMarker)

x,y,z = getElementPosition(getLocalPlayer()) 
weaponMarker = createMarker(x, y, z, "corona", 0.5, 255, 0, 0, 170) 
addEventHandler ( "onClientPreRender", root, 
function () 
if getPlayerWeapon(getLocalPlayer()) == 24 then 
muzX, muzY, muzZ = getPedWeaponMuzzlePosition(getLocalPlayer()) 
setElementPosition(weaponMarker,muzX, muzY, muzZ) 
end 
end) 

hmm i didn't try it but it should work

[Chrimam]

Uh it attaches marker to the weapon but i got a problem. whenever i look to an object (vehicles, peds or things added by scripts/maps), it creates a red marker on it (no it doesn't attach). and i don't want my marker to appear everytime i get desert eagle, i want it to appear when i aim. Hope you got the point (the red marker on my leg is the marker attached to the weapon)

[TAPL]

Try this: (Not Tested)

addEventHandler("onClientPreRender", root, 
function() 
    if getControlState("aim_weapon") and getPedWeapon(localPlayer) == 24 then 
        local muzX, muzY, muzZ = getPedWeaponMuzzlePosition(localPlayer) 
        if not isElement(weaponMarker) then 
            weaponMarker = createMarker(muzX, muzY, muzZ, "corona", 0.5, 255, 0, 0, 170) 
        end 
        setElementPosition(weaponMarker, muzX, muzY, muzZ) 
    else 
        if isElement(weaponMarker) then 
            destroyElement(weaponMarker) 
        end 
    end 
end) 

And, of course, you are the only who will see the marker when you aim (local player), other players won't see the marker.

[Chrimam]

Thank you guys it worked

P.S: I know it's client side. I don't want anybody to see my marker it will interrupt them. My project is a little bit different

[TAPL]

You're welcome.
