PHP код:
stock GetXYGridPos(Float:xs, Float:ys, &Float:x, &Float:y, Float:Angle, Index , Columns,  Float:xOffset, Float:yOffset)
{
//the values saved in x and y are the values saved into the variable you use in the function call param 3 and 4.
//the "Index" is defining which of the positions in the grid you want to calculate and get returned. 
//if we had two columns this would mean: 0 = front left, 1 = front right, 2 = row two left, 3 = row two right.. and so on.
 
    new i = Index%Columns; //modulus
    new j = floatround(Index, floatround_floor) / Columns; //normal division, rounding to nearest even number below the value.
    Calc_Point(xs, ys, Resultx, Resulty, xOffset, yOffset, Angle , i, j);
    x = Resultx; //x Position
    y = Resulty;//Y position
    
} 
You insert all the params. XY and R are centered. Index stands for the vehicle number you want to spawn. Columns stand for the amount of side-by-side lines. Offsets are individual distances between vehicles.

Let's say you want to make a boat race.
PHP код:
new pos[2];
for(new i;i<10;i++) //spawns 9 boats
{
GetXYGridPos(2000.0,2000.0, pos[0], pos[1], i, 0,  5.0, 10.0);
CreateVehicle(490,pos[0], pos[1],1.0,0.0,0,0,1000);
}

thank you very much

Код:
undefined symbol "Resultx" & undefined symbol "Resulty"

in:

stock Calc_Point(Float:xs, Float:ys, &Float:x, &Float:y, Float:xOffset, Float:yOffset, Float:Angle, i, j)
{
	//do further calculations with the params in last operation, find the next x and y values in the grid
	//x and yOffset is basically the space between the coordinates you calculate. Bigger value, bigger grid.
	x = xs +i * xOffset * floatcos(Angle,degrees) +j * yOffset * floatsin(Angle,degrees);
	y = ys + i * xOffset * floatsin(Angle,degrees) - j * yOffset * floatcos(Angle,degrees); //the two here is having + & + and + & - because of the coordinate system in samp.
} 

Help?
