The problem is: I'm trying to use math.ceil and tostring. To get the exact vehicle HP, and because the vehicles are created server-side and i can't just get the element hp. I needed to create an event. So everythign is perfect. But Health does not update.

Jaysds1 · February 25, 2012

Use OnVehicleDamage(Server-Sided) to update the health.

Replace

addEventHandler( "HP",root,

Or i think better create custom element.

And in client side loop this elements and check ( getElementHealth ,... )

Like this

Server

addEvent( "start",true ) 
addEventHandler( "start",root, 
    function( theElement ) 
        if theElement then 
            local uTrailerElement = createElement( 'uCars','uTrailer' ) 
            local uRootElement = createElement( 'uCars','uRoot' ) 
            mVehicle = createVehicle( 403, -22, -291, 6, 0, 0, 180 ) 
            mTrailer = createVehicle ( 435, -14, -285, 7, 0, 0, 180 ) 
            setElementParent( mVehicle,uRootElement ) 
            setElementParent( mTrailer,uTrailerElement ) 
            --warpPedIntoVehicle( theElement, mVehicle ) 
            warpPedIntoVehicle( theElement, uRootElement ) 
        end 
    end 
)

Client

function renderHP( ) 
    for _,v in pairs( getElementsByType 'uCars' ) then 
        if getElementType( v ) == 'uTrailer' then 
            dxDrawText( "HP(Trailer): " .. tostring( math.floor( getElementHealth( v ) ) ) .. "", sWidth/1.2,sHeight-57, sWidth, sHeight ) 
        end 
        if getElementType( v ) == 'uRoot' then 
            dxDrawText( "HP(Truck): " .. tostring( math.floor( getElementHealth( v ) ) ) .. "", sWidth/1.2,sHeight-47, sWidth, sHeight ) 
        end 
    end  
end

once again... bombarded with so many choices of fix...

(kenix... u should work on ur efficiency - i must admit tho... u do give me the odd giggle reading thru ur code)

another thing to look into once u have it working is, ur triggering all client events when u trigger,

im not sure if theres a reason for this but im guessing not...

im guessing that ur testing alone so this might not be an issue yet.

but basically: triggerClientEvent("HP",root,mVehicle,mTrailer) will be triggered for ALL clients...

u should be using: triggerClientEvent(thePlayerOnTheJob,"HP",root,mVehicle,mTrailer) which will only trigger for the player on the job.

(kenix... u should work on ur efficiency - i must admit tho... u do give me the odd giggle reading thru ur code)

Not understand you ...

triggerClientEvent("HP",root,mVehicle,mTrailer) will be triggered for ALL clients...

It's him code ,maybe he need trigger for all elements in tree.

https://wiki.multitheftauto.com/wiki/Element_tree

Scooby · February 25, 2012

well he doesnt need a loop just to get the health of 1 vehicle and 1 trailer, also, getting the health in onClientRender, rounding it etc... is less efficient than using a variable which can be updated when the vehicle health changes.. either by using setElementData or triggerClientEvent with an onVehicleDamage Event handler set to that vehicle.

while using scripts... try to think how they would work with 100 of the same running... also on server with a lot of people.

a working script is not the same as a script working efficiently.

Solid, Your code is winning so far.

Tho' it outputs me many errors in the debug they all say...

"ERROR: JobsONG//jobs_c.lua:37: bad argument #1 to 'ceil' (number expected, got nil)"... Whenever i crash the vehicle.

Kenix, your codes were correct but it had many errors that prevent the script from working. Thanks for the help anyways.

Scooby, actually it's only triggered by the localPlayer, tested with other people and works perfectly.

Castillo · February 25, 2012

Copy the server side again.

WolfPire · February 25, 2012

Copy the server side again.

Works now but we got 2 issues.

1. Trailer's HP will be "0". (Unless attached)

2. Trailer won't loose health.

Castillo · February 25, 2012

I've tried to damage the trailer in a lot of ways, but no luck, I think is not possible if you don't shoot at it.

WolfPire · February 25, 2012

I've tried to damage the trailer in a lot of ways, but no luck, I think is not possible if you don't shoot at it.

Possibly an MTA Problem?...

Well i'll just get the Truck's HP then.

EDIT:

function Fail( theVehicle ) 
    outputChatBox("Congratulations, you've earned a free...", source, 0, 255, 0) 
    setTimer( outputChatBox, 1000, 1, "GTFO.", source, 255, 0, 0 )

    triggerClientEvent("destroyFail",root, source) 
    if isElement(vehicles[source]["truck"]) then destroyElement(vehicles[source]["truck"]) end 
    if isElement(vehicles[source]["trailer"]) then destroyElement(vehicles[source]["trailer"]) end 
end

^ Server.

Doesn't work.

Castillo · February 26, 2012

What part doesn't work? I don't see any problem.

WolfPire · February 26, 2012

What part doesn't work? I don't see any problem.

When the vehicle explodes, it doesn't get destroyed.

Castillo · February 26, 2012

Copy the server side again, I've added to destroy the trailer when the truck explodes and if the trailer explodes it'll destroy the truck.

WolfPire · February 26, 2012

Console outputs error:

" ERROR: JobsONG/jobs_s.lua:56: ')' expected near 'kw2' " <---- ???

^ Another error with the same but saying that the loading of the script failed.

Castillo · February 26, 2012

That's a forum bug, copy the server side again, I removed the Lua tags.

WolfPire · February 26, 2012

That's a forum bug, copy the server side again, I removed the Lua tags.

Works like charm

Now one more thing, do the same. But as for when the player exit's the truck!

After that, i gotta test the reward part and we're done in here =)

P.S: In the explosión the text color doesn't change, any idea why this?

Castillo · February 26, 2012

When you exit the vehicle it should destroy both truck and trailer if exists, it doesn't work?

WolfPire · February 26, 2012

When you exit the vehicle it should destroy both truck and trailer if exists, it doesn't work?

Doesn't work then D:

Castillo · February 26, 2012

Yeah, my mistake , copy the server side again, now it works .

WolfPire · February 26, 2012

I get an error when touching the reward marker.

"ERROR: JobsONG/jobs_s.lua:72: bad argument #1 to 'ceil' (number expected, got boolean)"

Castillo · February 26, 2012

Yeah, I forgot to change some things, copy the server side script again.

WolfPire · February 26, 2012

It works now =D

My system is complete. Thank you =)

May i kiss you? Well.. better not if i'm not a girl.

Thanks for you help! Everyone!!!!

You're always welcome to my server in "Oriental Night Gaming"

Very confusing dxDrawText.
