Hi i want to get the Rotation X for a object according the player angle, but i dont know how to do this calculation, its possible?

[Babul]

the asin() and acos() functions will give you the results you need. besides the angle, you also need a radius. if you set the radius to 1.0, then the X-and Y-results will ne normalized.

I tried but he dont work.

PHP код:

Angle=  new Float:Angle;
GetPlayerFacingAngle(playerid, Angle);
X to point = -1412.1890 
Y to point = 2351.3638
My calcul = -1412.1890 * acos(Angle) - 2351.3638 * asin(Angle) 


Its wrong, i have an error with this calcul.

PHP код:

Float:PointAngle(playerid, Float:xa, Float:ya, Float:xb, Float:yb) 
{ 
    new Float:carangle; 
    new Float:xc, Float:yc; 
    new Float:angle; 
    xc = floatabs(floatsub(xa,xb)); 
    yc = floatabs(floatsub(ya,yb)); 
    if (yc == 0.0 || xc == 0.0) 
    { 
        if(yc == 0 && xc > 0) angle = 0.0; 
        else if(yc == 0 && xc < 0) angle = 180.0; 
        else if(yc > 0 && xc == 0) angle = 90.0; 
        else if(yc < 0 && xc == 0) angle = 270.0; 
        else if(yc == 0 && xc == 0) angle = 0.0; 
    } 
    else 
    { 
        angle = atan(xc/yc); 
        if(xb > xa && yb <= ya) angle += 90.0; 
        else if(xb <= xa && yb < ya) angle = floatsub(90.0, angle); 
        else if(xb < xa && yb >= ya) angle -= 90.0; 
        else if(xb >= xa && yb > ya) angle = floatsub(270.0, angle); 
    } 
    GetVehicleZAngle(GetPlayerVehicleID(playerid), carangle); 
    return floatadd(angle, -carangle); 
} 


Wrong Rotation isnt X but thanks you.
