Objects! - Juvanii - 09.08.2014

How to make a function "stock" to create the object in front of the player with the correct rotation floats of the object? I tried a lot but failed!
The player's facing angle differs when he's looking at north,south,east,west!

It must be any stock to create the object in the right position with the correct object's rotation floats!!

We are here to help you with your scripting problems, meaning you have to at least provide some code to look at, not your 'script this stock for me' "problem".

GetXYInFrontOfPlayer(playerid, &Float:x, &Float:y, Float:distance)
{
    new Float:a;
    GetPlayerPos(playerid, x, y, a);
    GetPlayerFacingAngle(playerid, a);
    if (GetPlayerVehicleID(playerid))
    {
        GetVehicleZAngle(GetPlayerVehicleID(playerid), a);
    }
    x += (distance * floatsin(-a, degrees));
    y += (distance * floatcos(-a, degrees));
}

What code are you talkin about? All the problem is: i can't control the facing angle of the player to create an object in front of him with the correct object's rotations.

It worked after i subtract 1 from the float X and Y but when the player is looking at north or south, the object is created behind the player.

Edit: @Mionee should i use this under the command with getting the player's floats first?

There is a very easy solution to this problem as a matter of fact and I explained this the other day.

You need the function in this thread.

Why do you want to attach object to object? Why should i use this?

Yes, you do it like this:

pawn Код:

new Float: pX, Float: pY, Float: pZ;
GetPlayerPos(playerid, X, Y, Z);
GetXYInfrontOfPlayer(playerid, X, Y, 5.0);

As demonstrated here: https://sampwiki.blast.hk/wiki/Stocks#Re...ultiple_values (src: https://sampforum.blast.hk/showthread.php?tid=510662)

Re: Objects! - Juvanii - 09.08.2014

How about the object Z float and the rotations? do i use it as player's Z Float?

Re: Objects! - Dignity - 09.08.2014

If you mean placing the object on the ground, try adding -1.0 (or more) after "Z".

Sorry I forgot to mention you need a slightly modded function.
