projectile How to change a projectile's blip color?

[Lord Henry]

Hello.
I have a script that create a missile that follows the player when he enters the specified collision shape using createProjectile.
The projectile elements have a white blip by default and I need to change it to Red.
Is there a way to do it?

[Mr.Loki]

Try this:

getAttachedElements

setBlipColor

getAttachedElements doesn't work, because it returns a table, not the element.

If you didn't read carefuly enough function name is getAttachedElements not getAttachedElement. Just loop through that table it will get ALL attached elements, 'cause there can be more than 1 attached element to an element. Just in case if you have other elements attached to the projectile then just add check variable if element is the blip and then set blip color.

for i,v in ipairs(getAttachedElements(yourProjectileElementHere) do
    setBlipColor(v,255,0,0,255);
end

A table containing the element

In order to reduce lag, you should use 

for i,v in pairs(getAttachedElements(yourProjectileElementHere) do
    setBlipColor(v,255,0,0,255);
end

instead of

for i,v in ipairs(getAttachedElements(yourProjectileElementHere) do
    setBlipColor(v,255,0,0,255);
end

'Cause you don't need to order the execution.

When I use this, the Projectile is not spawned anymore.

Hey guys, test using this, client-side:
 

function attackIntruderA51 ()
	local a51MissileA = createProjectile (localPlayer, 20, 15.49994, 1719.1, 25.5, 5, localPlayer, 0, 0, 0, 0, 0, 1)
	local a51MissileB = createProjectile (localPlayer, 20, 237.7, 1696.8, 25.5, 5, localPlayer, 0, 0, 0, 0, 0, 1)
end
addCommandHandler ("attack", localPlayer, attackIntruderA51)

addCommandHandler only has 2 main args please use /debugscript 3 to debug your code and show errors

I just tried the function myself and it seems that the blip isn't attached to the projectile so, i just made a little hack.

Not perfect but it works.

function attackIntruderA51 ()
    local t={}
    -- store the projectiles in a table so you can simply loops it and easily add more projectiles.
    t[#t+1] = createProjectile (localPlayer, 20, 15.49994, 1719.1, 25.5, 5, localPlayer, 0, 0, 0, 0, 0, 1)
    t[#t+1] = createProjectile (localPlayer, 20, 237.7, 1696.8, 25.5, 5, localPlayer, 0, 0, 0, 0, 0, 1)
  
    for _,projectile in pairs (t) do
        local blip = createBlipAttachedTo( projectile, 0, 1, 255, 0, 0, 255, 1 )
        setElementParent( blip, projectile ) -- parent the blip to the projectile so it gets destroyed when the projectile explodes.
    end
end
addCommandHandler ("attack", attackIntruderA51)

I'm already doing this. But sometimes the original Projectile's blip keep upon the custom blip, even if I put the ordering arg to 32767.

Damn... then i have no idea how lol

you could destroy original blip with destroyElement and then create your own.

I can't access the original blip. If I could, I would just change the original blip's color.
