How to attach players to vehicles...

[The_Stig]

Hey all,

Been in a few servers recently and noticed that you can 'stick' to peoples vehicles yet in my server they all just fall off.

How do i go about doing this as it is very cool on planes

Cheers.

[Stevvo]

Use this Function:

[The_Stig]

Thanks for the swift reply

Being i am a complete n00b at scripting how do i go about making this script do this for all vehicles?

cheers.

[mdm13]

Yes good one, I would like to know also. I need this script very bad for my server. I guez it's a big secret...perhaps resource release on dp3. Let's hope

[Vercetti1010]

our server needs this command too. the wiki entry doesnt help all that much. i need to make it so that the person in the vehicle sticks a player on his vehicle. i have no idea how to script that though. can i get some help? lol

[XetaQuake]

i need it too

[Woovie]

So... I got it working =) It is really simple.

!!!!I WOULD RECOMMEND WAITING FOR MY FINAL SCRIPT RELEASE!!!!

I need to make it all ONE command, with A LOT more options.

This sticks your player to a vehicle, with XYZ relative to the vehicle they are in.

  
function cmd_stick ( player, commandName, player2nick, x, y, z ) 
    local player2 = getPlayerFromNick ( player2nick ) 
    local vehicle = getPlayerOccupiedVehicle  ( player2 ) 
    attachElementToElement ( player, vehicle, x, y, z  ) 
end 
addCommandHandler ( "stick", cmd_stick ) 
  
function cmd_unstick ( player, commandName ) 
    local vehicle = getElementAttachedTo ( player ) 
    detachElementFromElement ( vehicle ) 
end 
addCommandHandler ( "unstick", cmd_unstick )

Means that you will make a public Release and post it in the Scripting board when you are finish?

Doesn't work.

Debugged it and get errors on line 4 and 10.

[OffRoader23]

Works in our script...not sure, I'm working on it right now, to get it to store if the player is stuck or not, and then it will check when you try to /stick again so it can unstick you then restick automatically, or just unstick all together if no parameters specified.

If it errors on line 4 and 10 then its not sending the player variable correctly when the player does the command.

Are you doing /stick name 0 0 0 ?

Heres the updated code that is running/working on our server [Free Roam Chaos]:

function cmd_stick ( player, commandName, player2nick, x, y, z ) 
    local player2 = getPlayerFromNick ( player2nick ) 
    local vehicle = getPlayerOccupiedVehicle  ( player2 ) 
    if isPlayerInVehicle ( player ) then 
        removePlayerFromVehicle ( player ) 
        detachElementFromElement( player ) 
        attachElementToElement ( player, vehicle, x, y, z  ) 
    else 
        detachElementFromElement( player ) 
        attachElementToElement ( player, vehicle, x, y, z  ) 
    end 
end 
addCommandHandler ( "stick", cmd_stick ) 
  
function cmd_stickv ( player, commandName, player2nick, x, y, z ) 
    if isPlayerInVehicle ( player ) then 
        local playerv = getPlayerOccupiedVehicle  ( player ) 
        local player2 = getPlayerFromNick ( player2nick ) 
        local vehicle = getPlayerOccupiedVehicle  ( player2 ) 
        detachElementFromElement( playerv ) 
        attachElementToElement ( playerv, vehicle, x, y, z ) 
    else 
        detachElementFromElement( player ) 
        attachElementToElement ( player, vehicle, x, y, z  ) 
    end 
end 
addCommandHandler ( "stickv", cmd_stickv ) 
  
function cmd_unstick ( player ) 
    element = getElementAttachedTo ( player ) 
    detachElementFromElement( player ) 
    if isPlayerInVehicle ( player2 ) then 
        local vehicle = getPlayerOccupiedVehicle  ( player ) 
        detachElementFromElement( vehicle ) 
    else 
        detachElementFromElement( player ) 
    end 
end 
addCommandHandler ( "unstick", cmd_unstick ) 

/stick Playername X Y Z - sticks you to the players vehicle only (removes you from vehicle if your in one)

/stickv Playername X Y Z - sticks you and your vehicle to the players vehicle

/unstick - unsticks your car/player

X Y Z is the offset from the other players car, usually start out with a Z of 1 and you should be good. Play with the X (left/right) Y(front/back) Z (above/below) to get exactly where you want to be on the car.

Hope this works for someone.

[The_Stig]

Hmmmmmm

Ok now i wasnt doing /stick name 0.0.0

I thought it would be a simple case of just either jumping on the players car or just with your script typing /stick.

[OffRoader23]

Yeah that would take a complex math calculation, Me and LeetWoovie are trying to work on it now but it has to calculate the cars position and the players position and the cars rotation then has to find exactly where your standing and since GTA uses relative N S E W not relative to the car its kind of hard to do it without some complex math calculation...of some sort, that I'm not exactly sure on. I will see what happens with our script.

[Woovie]

Yeah, I definitely tried calculating the world location of the car, the player, finding the difference and placing you there, but man, it REALLY messes up.

[fgwelder]

there is a way to have it just detect when you jump onto a car or a vehicle..

I don't use it, since it is kinda buggy, and if you want to ride on a plane, and move once you just fall through, and car sticking is buggy..

I got the clientside code from AlienX's server, and I have made my own server side handeler for it.

Haven't really tested it.. since all I did was do this just to post here, and don't actually use it.. But it seems to work decently. Not that well though, since moving once will detach you from a plane..

[tma]

I had a go at this kind of thing - it produces some weird results (

).

The fences are part of the map (manager). The barrels I create. Neither has collision while attached, but the created vehicles do (dinghies trapped in the "cage" and then stuck to my car).

Edit : I have to go to the remote cam because the attached dinghies block the driver view. Also, the weight of the dingies on the car pushes the front down enough for it to lift the rear end.

Just tried this and it works great.

We mainly use it for a bit of fun really using planes and this is perfect.

Thanks :D

i get this error:

i get this error:

you got the meta.xml right? remember it's a clientside script

[Woovie]

In your meta do this

[XetaQuake]

thanks, i have copy a meta.xml from another resource and have just change the name of the scripts, but i have forgot to set the client/server stuff correct

but yes its realy bugy i think

[mdm13]

hey this script is nice...I was just wondering is it possible to also shoot whilst being on vehicle. I noticed my weapons disappear when I enter the top of the vehicle. Anyone knows how to change this?

[Guest]

My Script:

http://www.dailymotion.com/Kr0tchy/vide ... videogames

[Twig]

Last time I checked AlienX's server the script being used calculated the offsets wrong, I can't believe nobody's mentioned this.....

[norby89]

Last time I checked AlienX's server the script being used calculated the offsets wrong, I can't believe nobody's mentioned this.....

it depends on the vehicles rotation, if it's ( 0 0 x ) it works otherwise it gets it wrong

[Twig]

It still seemed wrong even in that case when I used it.

Like say you jumped on the front of the car it'd glue you a metre off the left of it or something similar. I fixed it by changing the math used but it's strange no-one else has mentioned it.
