"OnPlayerLookAtVehicle" - Detect if a player is looking at some vehicle. - iPLEOMAX - 12.01.2012

OnPlayerLookAtVehicle V2*

Info:
Detects if a player is looking at any vehicle and executes a callback on any change.

How it works:
Uses Camera Vector, Position, Streamed Vehicles & your distance between the vehicle to calculate, etc..

Callback & Natives:

pawn Код:

//To Enable this for a player. (If you forget to do this, it won't work!)
EnableVehicleLookAt(playerid);

//The following Callback is called when a player has his camera's point of view towards a vehicle.
public OnPlayerLookAtVehicle(playerid, vehicleid, Float:distance)
{
    new message[128];
    format(message, sizeof message,
    "You are looking at vehicle id %i with a distance of %f meters.", vehicleid, distance);
    SendClientMessage(playerid, -1, message);
    return true;
}

//To disable the lookat system for a player. (Good thing to put it under OnPlayerDisconnect)
DisableVehicleLookAt(playerid);

Are you looking for IsPlayerLookingAt(vehicle ... object ... player) ?

What can I do with it?
Few ideas:
- Make a showroom featuring TDU2's style. (I have done one)
Don't get it? I mean, if you point at any vehicle, it shows up it's name, price, top speed etc with textdraws. (It's cool TBH).

-Making other such thingies

I was in need of this. Thanks!

I took a look at the code, and seems good scripted and faster. It's very useful though but i didn't understand what EnableVehicleLookAt(playerid); function is used for. Yes for enable/disable the function for a player but why? Good job tough.

Nothing much actually.. I thought adding these functions would be better because sometimes you don't wanna run this system on each player all the time.. Too much for nothing.

Upto you guys, like Enable on Connect & done! It'll stay active all the time.

Thanks & Alright, I'll post a foreach+y_hooks version too just in case (But I guess 'foreach' wouldn't make much difference here though).

There's no other way you could do it. (Atleast in my head)

To get the vehicle on a player's sight, you WILL NEED these positions/calculations and a timer.

You said: "its laggy what you did..."

Do you or anyone else have a better method? I'm not being angry, I'm just asking so it would be good for everyone else if you had one..

Nice looks like you directed it more at RP servers. Would be nice to see some other things like perhaps OnPlayerShootVehicle I need a call back like this for health hack detection :P
