[EvoGT]

Hello Scripters

is it possible to:

to check if there's a vehicle with processLineOfSight

and decrease their health and draw a line using dxDrawLine3D.

Please help me how to do this.

You said it all.. You already know the functions and what to do, there are examples for each function in the wiki. What do you expect us to tell you now?

I need help in scripting it.

i tryed but nothing worked.

So, maybe mta community will try to script it.

I think that the script will not be long

I would be very grateful

[Anderl]

Then next time post the code you tried.

[EvoGT]

I did something like this

                  processLineOfSight ( float startX, float startY, float startZ,  
                                       float endX, float endY, float endZ,  
                                       [ bool checkBuildings = true,  
                                       bool checkVehicles = true,  
  

LoL..

I dont know how to start..

Help me to do this script .

Required Arguments

startX: The start x position

startY: The start y position

startZ: The start z position

endX: The end x position

endY: The end y position

endZ: The end z position

Optional Arguments

NOTE: When using optional arguments, you must supply all arguments before the one you wish to use. For more information on optional arguments, see Optional Arguments.

checkBuildings: Allow the line of sight to be blocked by GTA's internally placed buildings, i.e. the world map.

checkVehicles: Allow the line of sight to be blocked by vehicles.

checkPlayers: Allow the line of sight to be blocked by players.

checkObjects: Allow the line of sight to be blocked by objects.

checkDummies: Allow the line of sight to be blocked by GTA's internal dummies. These are not used in the current MTA version so this argument can be set to false.

seeThroughStuff: Allow the line of sight to be blocked by translucent game objects, e.g. glass.

ignoreSomeObjectsForCamera: Allow the line of sight to pass through objects that have (K) property enabled in "object.dat" data file. (i.e. Most dynamic objects like boxes or barrels)

shootThroughStuff: Allow the line of sight to be blocked by things that can be shot through

ignoredElement: Allow the line of sight to pass through a certain specified element. This is usually set to the object you are tracing from so it does not interfere with the results.

includeWorldModelInformation : Include the results of hitting a world model.

Maybe i can use this

function fireandcreate () 
    local weapon = createWeapon("mp5",0,0,0) --Create a Mp5 at the Cordinates 0,0,0 
    fireWeapon(weapon) --Fires the Weapon 
end 

?

[EvoGT]

Thanks guys for your post's, but i dont know what you writed : X

function fireandcreate () 
    local weapon = createWeapon("mp5",0,0,0) --Create a Mp5 at the Cordinates 0,0,0 
    fireWeapon(weapon) --Fires the Weapon 
end 

?

  
    local weapon = createWeapon("mp5",0,0,0) --Create a Mp5 at the Cordinates 0,0,0 
function fireWeapon () 
   setWeaponState ( weapon,"firing") 
end 
  

[Anderl]

  
    local weapon = createWeapon("mp5",0,0,0) --Create a Mp5 at the Cordinates 0,0,0 
function fireWeapon () 
   setWeaponState ( weapon,"firing") 
end 
  

There is fireWeapon for that, it just needs to be called multiple times because it only shots one bullet per call.

Maybe is it possible to bind it ?

Like i press "O"

And the weapon shot until i press O ?

[Anderl]

You can do that using bindKey, using key state "both".

[EvoGT]

Okey, if i'l bind it.

But what should i do to put that shotting gun on the car ( where is weapon )

[Anderl]

I'm not sure if attachElements function supports weapon elements (most likely not, since it's not in the supported element types list in the wiki's page), however you can try: create a weapon and use attachElements using the element returned by the function createWeapon.

[EvoGT]

Tottaly mest up..

ok i will try to bind it .

heh.

  
    local weapon = createWeapon("m4",0,0,0) --Create a Mp5 at the Cordinates 0,0,0 
function fireWeapon () 
   setWeaponState ( weapon,"firing") 
end 
  
bindKey ( string mouse1, string both, function handlerFunction,  [ var arguments, ... ] ) 
function fireWeapon ( string moise1, string both, [ var arguments, ... ] ) 

im soo bad at scripting : X

[Anderl]

Well, then learn the language: http://lua.org

The wiki wasn't made to be copy+pasted. What you're copying is the function syntax which has COMPLETELY NOTHING to do.

Then don't begin scripting if you can't understand it.

And no, we can not make a bind for you as you can't even try properly.

@EvoGT,

We can help you with scripting but we can't create the script for you. You need to learn Lua first and then you can start scripting. If you can't learn then how do you expect us to help you? By creating the ready script for you? This way you will not learn. There are many script out there already which you can learn from. Everyone has to start somewhere. If you'll learn the basics you will learn more quickly how to make your own scripts. Also, check my resources (link in signature), I have created some basic scripts which can help you learn.

I'm not sure if attachElements function supports weapon elements (most likely not, since it's not in the supported element types list in the wiki's page), however you can try: create a weapon and use attachElements using the element returned by the function createWeapon.

Weapons are supported by attachElements and you can attach weapons to vehicles but you can only manipulate weapons on client-side only. If you change the weapon state for one client then it will only be changed for this client (other clients don't even know that you created a weapon for yourself). When you create a weapon for 1 client then you have to create it for everyone. When you change weapon's state for 1 player, make sure you change it for everyone. If you change it for 1 client only and if another vehicle explodes then it will only explode your that 1 player. Even the other player sitting in that vehicle will be alive and "driving wrecked vehicle" (that's what player who shot will see on their screen). You have to sync weapons yourself.
