vehicle facing angle - cruising - 14.01.2012

Hello!

I have this, it gets "GetVehiclePos" and "VehicleZAngle"
CODE:

pawn Код:

VehicleFire[id] = 1;

                        if(IsValidObject(VehicleBomb[id][0]))
                        {
                            DestroyObject(VehicleBomb[id][0]);

                            GetVehiclePos(id,x,y,z);
                            GetVehicleZAngle(id,a);

                            a += 270;
                            z += VehicleOffsetZ[id];

                            x += (VehicleOffsetX[id] * floatsin(-a, degrees));
                            y += (VehicleOffsetX[id] * floatcos(-a, degrees));

                            VehicleBomb[id][0] = CreateObject(3790,x,y,z,2,0,a,300.0);
                            VehicleSmok[id][0] = CreateObject(18731,x,y,z-1.3,0,0,0,300.0);

                            a += 90;

                            x += (300 * floatsin(-a, degrees));
                            y += (300 * floatcos(-a, degrees));

                            MoveObject(VehicleBomb[id][0],x,y,z,MISSILE_SPEED);
                            MoveObject(VehicleSmok[id][0],x,y,z-1.3,MISSILE_SPEED);

                            SetTimerEx("VM_Explode",MISSILE_DETONATE_TIME,0,"dd",id,0);
                            VM_OnVehicleFire(id,0);
                            return 1;
                        }
                        DestroyObject(VehicleBomb[id][1]);

                        GetVehiclePos(id,x,y,z);
                        GetVehicleZAngle(id,a);

                        a += 90;
                        z += VehicleOffsetZ[id];

                        x += (VehicleOffsetX[id] * floatsin(-a, degrees));
                        y += (VehicleOffsetX[id] * floatcos(-a, degrees));

                        VehicleBomb[id][1] = CreateObject(3790,x,y,z,2,0,a+180,300.0);
                        VehicleSmok[id][1] = CreateObject(18731,x,y,z-1.3,0,0,0,300.0);

                        a += 270;

                        x += (300 * floatsin(-a, degrees));
                        y += (300 * floatcos(-a, degrees));

                        MoveObject(VehicleBomb[id][1],x,y,z,MISSILE_SPEED);
                        MoveObject(VehicleSmok[id][1],x,y,z-1.3,MISSILE_SPEED);

                        SetTimerEx("VM_Explode",MISSILE_DETONATE_TIME,0,"dd",id,1);
                        VM_OnVehicleFire(id,1);

But how do i get the facing angle of the vehicles front? i mean if you facing up/down etc?
I want the objects also to move up and down depending on your vehicle front facing angle so the objects don't just moves straight from your position.

Anyone who have any idea?

You would need to use GetVehicleRotationQuat
But since its very advanced maths I cant help you with that

The best thing I would suggest is to search through this forum for a function that converts quat to euler angles

Re: vehicle facing angle - Lorenc_ - 15.01.2012

pawn Код:

stock IsVehicleUpsideDown(vehicleid)
{
    new Float:quat_w,Float:quat_x,Float:quat_y,Float:quat_z;
    GetVehicleRotationQuat(vehicleid,quat_w,quat_x,quat_y,quat_z);
    new Float:y = atan2(2*((quat_y*quat_z)+(quat_w*quat_x)),(quat_w*quat_w)-(quat_x*quat_x)-(quat_y*quat_y)+(quat_z*quat_z));
    return (y > 90 || y < -90);
}

This can be somewhat useful for your work planned, enjoy...

Yeah i was looking on that Quat, but i didn't understand a thing about it. And im not that good at math nor.

Thanks!
Is this just a part of what i need or is this enough to use for the plans?
