GetXYZInFrontOfVehicle ? - NopeNope - 01.05.2014

How i can do this? Thank you for response.

Re: GetXYZInFrontOfVehicle ? - JacobEdwards - 01.05.2014

Here is the code for GetXYInFrontOfVehicle()

pawn Код:

GetXYInFrontOfVehicle(playerid, &Float:x, &Float:y, Float:distance)
{
    new Float:a;
    GetVehiclePos(playerid, x, y, a);
    GetVehicleZAngle(playerid, a);
    x += (distance * floatsin(-a, degrees));
    y += (distance * floatcos(-a, degrees));
}

Yeah, but i need Z-axis.
I have this code: http://pastebin.com/uDz10QEQ
But this doesnt' work properly, the checkpoint don't appears sometimes.
Sorry for my bad english

You need the z (height) and that can be found by GetVehiclePos function. I added + 1 to the current height just to prevent it to be underground. If it's over the ground though, you can remove it.

pawn Код:

GetXYZInFrontOfVehicle(vehicleid, &Float:x, &Float:y, &Float:z, Float:distance)
{
    new Float:a;
    GetVehiclePos(playerid, x, y, z);
    GetVehicleZAngle(playerid, a);
    x += (distance * floatsin(-a, degrees));
    y += (distance * floatcos(-a, degrees));
    z += 1.0;
}

You don't need the rotations of the vehicle.

Okay, thank you.
But i have a problem, when i enter in a car and i rotate it, the checkpoint appears in another position.

Re: GetXYZInFrontOfVehicle ? - Konstantinos - 01.05.2014

Do you create the checkpoint after entering the car or before?

EDIT: I create the checkpoint when im in a house (interior).

Re: GetXYZInFrontOfVehicle ? - Konstantinos - 01.05.2014

So you're not in the car. I'm not sure but I think there's a bug with SetVehicleZAngle function and it won't set the angle if the vehicle is not occupied. So it might return the previous angle and that's why it doesn't create it in front of it.

So? I can't? I must create the checkpoint behind the car but the coord are wrong. I don't know how to do...

You serious? All you've done is adding +1 to Z coord, that is not correct way to do it xD
