how to know if a vehicle model is trailer

[Lovono 5]

Hi everybody,

Is there anyway we can detect if a model is a trailer so we can use the funciton:

ATTACH_VEHICLE_TO_TRAILER

Thank

 

Update:

The awesome answer is post #12 , thank 123iamking

Use this function

int GET_ENTITY_TYPE(Entity entity) // 8ACD366038D14505 0B1BD08DReturns:1 = peds2 = cars3 = objects14 = SCRIPT_GLASS_PANE13 = SCRIPT_TRAIN12 = SCRIPT_TRAILER11 = PLAYER10 = SCRIPT_SUBMARINE9 = SCRIPT_PLANE8 = SCRIPT_PICKUP_PLACEMENT7 = SCRIPT_PICKUP6 =5 =4 =3 = SCRIPT_DOOR2 = SCRIPT_BOAT1 = SCRIPT_BIKE0 = SCRIPT_AUTOMOBILE

 

Or you can check if the model is contained within a list of the trailer models, which are

0xA7FF33F50x9E6B14D60xE82AE6560x1F3D44B50x806EFBEE0xD1ABB6660x3CC7F5960x153E1B0A0x174CB1720x782A236D0xCBB2BE0E0xA1DA3C910x8548036D0x2A72BEAB0x967620BE

The GET_ENTITY_TYPE function would be the ideal way to go though because if there are more trailers added later you won't have to update your mod to add them.

Or use the functions given in post #12.

GetEntityType only returns if its an object, ped or vehicle. not if its a trailer

But it says "12 = SCRIPT_TRAILER"?

Ah, since there is no native function help that, I think the solution 2 seems great.

But what strange is that there are native functions like:

IS_THIS_MODEL_A_PLANE_IS_THIS_MODEL_AN_EMERGENCY_BOATIS_THIS_MODEL_A_BOATIS_THIS_MODEL_A_HELIIS_THIS_MODEL_A_CARIS_THIS_MODEL_A_TRAIN...

So I think there should be a native to determine if it's the trailer model, maybe we still haven't found it yet.

You can probably check for the position of the trailer hitch receiver bone. If it isnt 0,0,0, its a trailer.

that only works if it's spawned though. Also checking if boneindex is -1 would be easier. Edited August 1, 2016 by unknown modder

I assume its already spawned since he's trying to attach it to a vehicle. You're right, checking the boneIndex would be better. I'm just going off the top of my head.

But the native can literally only return 0(not an entity), 1, 2 or 3

It's best to check before spawning, Imagine you want to draw a list of trailer to attach. I need a native function to check model trailer because who knows when will R* add new trailer model for the next DLC/Update.

[123iamking 20]

Here is how it's done

you can use 2 native function

VEHICLE::_GET_VEHICLE_MAX_SPEED(vehModel)//Later the function renamed to VEHICLE::_GET_VEHICLE_MODEL_MAX_SPEED by the authorVEHICLE::GET_VEHICLE_MODEL_ACCELERATION(vehModel))

The trailer always has the acceleration as 0, no doubt. And the speed as negative (-0.51). Just check a vehicle model if the acc is 0 or spd is negative and there you go.

Have fun

Thank you for join my topic

Did you try this native function

BOOL _GET_VEHICLE_OWNER(Vehicle vehicle, Entity* entity)//0x8F5EBAB1F260CFCE

Param:

The entity should be Michael, Trevor, Franklin ped, and vehicle is the vehicle you want to check

i didn't understand the param section can u please give an example

​That code would require you to know the Ped handles of each player. I don't know how to get each player's ped so I'll just give you the code regarding _GET_VEHICLE_OWNER.

Ped michaelPed = /*get michael ped*/, trevorPed = /*get trevor ped*/, franklinPed = /*get franklin ped*/;Vehicle veh = /*vehicle you are checking*/;OutputArgument outArg = new OutputArgument();if (GTA.Native.Function.Call<bool>(Hash._GET_VEHICLE_OWNER, veh, outArg)){    Ped owner = (Ped)outArg.GetResult<Entity>(); //can you just cast it or should you use GET_PED_INDEX_FROM_ENTITY_INDEX?    if (owner == michaelPed)    {        //...    }    else if //...​}​else GTA.UI.Notify("No owner found");

you dont need to use GET_PED_INDEX_FROM_ENTITY_INDEX, that native seems like its what R* use to cast an entity to a ped in the scripts, but in reality it just returns whatever was passed to it

​Thanks for the info!
