Facing Angle - Juvanii - 04.08.2014

Any ideas how to make the player stare at other player near him?
i made something like this: but doesn't work perfectly!

pawn Код:

new Float:a, targetid;
GetPlayerFacingAngle(targetid, a);
SetPlayerFacingAngle(playerid, -a);

Re: Facing Angle - DiGiTaL_AnGeL - 04.08.2014

Well, how do you get "targetid"'s value? And how doesn't it work perfectly?

Re: Facing Angle - ViniBorn - 04.08.2014

pawn Код:

SetPlayerToFacePlayer(playerid, targetid)
{

    new
        Float:pX,
        Float:pY,
        Float:pZ,
        Float:X,
        Float:Y,
        Float:Z,
        Float:ang;

    if(!IsPlayerConnected(playerid) || !IsPlayerConnected(targetid)) return 0;

    GetPlayerPos(targetid, X, Y, Z);
    GetPlayerPos(playerid, pX, pY, pZ);

    if( Y > pY ) ang = (-acos((X - pX) / floatsqroot((X - pX)*(X - pX) + (Y - pY)*(Y - pY))) - 90.0);
    else if( Y < pY && X < pX ) ang = (acos((X - pX) / floatsqroot((X - pX)*(X - pX) + (Y - pY)*(Y - pY))) - 450.0);
    else if( Y < pY ) ang = (acos((X - pX) / floatsqroot((X - pX)*(X - pX) + (Y - pY)*(Y - pY))) - 90.0);

    if(X > pX) ang = (floatabs(floatabs(ang) + 180.0));
    else ang = (floatabs(ang) - 180.0);
    
    SetPlayerFacingAngle(playerid, ang);

    return 0;

}//include a_angles

Look this

nevermind about that, i'm using the targetid in some cmd and i want to add this feature and wanna know how could it work!

@ViniBorn do i have to download a .inc file for this!!

Re: Facing Angle - ViniBorn - 04.08.2014

You don't need to download anything, only use that code...

AW: Facing Angle - Nero_3D - 04.08.2014

Well I don't know why this function still gets spread but I think people don't know it better, this code is enough

pawn Код:

SetPlayerToFacePlayer(playerid, targetid) {
    new
        Float: pX,
        Float: pY,
        Float: tX,
        Float: tY
    ;
    return
        GetPlayerPos(targetid, tX, tY, Float: targetid) &&
        GetPlayerPos(playerid, pX, pY, Float: targetid) &&
        SetPlayerFacingAngle(playerid, -atan2(tX - pX, tY - pY))
    ;
}

there are no errors on compiling.
but when using it in the cmd:

@Nero_3D Also no errors on compiling but when using it:

AW: Facing Angle - Nero_3D - 04.08.2014

These warning and errors appear because you already have a variable called pX and pY declared as global
I won't tell you how to name your global variables but I advise you to add some indicator like the letter 'g' at the beginning

To fix that without changing any of your code just rename the local variables (from 'p' to 'a')

pawn Код:

SetPlayerToFacePlayer(playerid, targetid) {
    new
        Float: aX,
        Float: aY,
        Float: tX,
        Float: tY
    ;
    return
        GetPlayerPos(targetid, tX, tY, Float: targetid) &&
        GetPlayerPos(playerid, aX, aY, Float: targetid) &&
        SetPlayerFacingAngle(playerid, -atan2(tX - aX, tY - aY))
    ;
}

thanks didn't notice that! compiling with no errors but not tested yet!
