Hello guys I want to make a simple drift system, but I have no idea how to check if player drifts! Can somebody explain me? I mean with piece of code and explanation. I need to know just how to check it.

its very easy you compare vehicle angle to its moving vector angle and thats about it.

code example?

simple example of drifting system, haven't tested it yet
you have to add checks and other stuff there to make it really work like needed.
i just wrote simple optimized starting code of it.

PHP код:

//code made by : codExpert // 13.01.19
#include <YSI_Coding\y_timers>
//variables - needed to stop drifting angle spam you have to build this yourself
new Float:pVehLastAngle[MAX_PLAYERS];
//params resets
public OnPlayerEnterVehicle(playerid,vehicleid,ispassenger){
    pVehLastAngle[playerid]=0.0;
    return 1;
}
//functions related with system
bool:vehTypeCar(modelID){
    switch(modelID){
        case 480,533,439,555,536,575,534,567,535,566,576,412,445,504,401,518,527,542,507,562,585,419,526,604,466,492,474,546,517,410,
        551,516,467,426,436,547,405,580,560,550,549,540,491,529,421,602,429,496,402,541,415,589,587,565,494,502,503,411,559,603,
        475,506,451,558,477,418,404,479,458,561: return true;
    }
    return false;
}
GetAngleToXY(Float:X, Float:Y, Float:CurrentX, Float:CurrentY, &Float:Angle){
    Angle = atan2(Y-CurrentY, X-CurrentX);
    Angle = floatsub(Angle, 90.0);
    if(Angle < 0.0) Angle = floatadd(Angle, 360.0);
}
GetVehicleHeadingAngle(vehicleid, &Float:a){
    new Float:x, Float:y, Float:z;
    GetVehicleVelocity(vehicleid, x, y, z);
    GetAngleToXY(x, y, 0.0, 0.0, a);
}
//makes timer more accurate and easier to create
ptask PlayerDriftChecker[500](playerid){
    //checks if player is driver
    if( GetPlayerState(playerid)==PLAYER_STATE_DRIVER){
        new vehID=GetPlayerVehicleID(playerid);
            vehModel=GetVehicleModel(vehID);
        //checks if vehicle model type is car
        if(vehTypeCar(vehModel)){
            new Float:vehAngle=GetVehicleZAngle(vehID),
                Float:vehHeadingAngle,
                Float:angleDifference;
            GetVehicleHeadingAngle(vehID, vehHeadingAngle);
            //checking the angle difference
            if((angleDifference=floatabs(vehAngle-vehHeadingAngle)) > 45.0){
                new s[60];
                format(s,60,"Drifting angle : %.2d",angleDifference);
                SendClientMessage(playerid,-1,s);
            }
        }
    }
}
