Hello.
I have a picture here:

I have one dot already placed, and I need to place other dots on
the circle and know their coordinates.

I know the lenght of circle ©, radius®, number of dots needed
and the distance between points. I must place them all
in circle. Please notice that sizes C,r,distance may change.
I need a formula to find the coordinates of every point.
I have made a better drawing:
P.S. Coordinates can be a rational number (5.6,10.8 etc.)
Thanks for any help.

You only need to know the center of your circle and your first point

That function rotates that point by the given angle around the center

pawn Код:

stock GetNextPointOnCircle(Float: cX, Float: cY, & Float: X, & Float: Y, Float: angle, const amode = degrees) {
    new
        Float: cos = floatcos(angle, amode),
        Float: sin = floatsin(angle, amode),
        Float: tX = X - cX,
        Float: tY = Y - cY
    ; // source - en.wikipedia.org/wiki/Rotation_matrix
    X = tX * cos - tY * sin + cX;
    Y = tX * sin + tY * cos + cY;
}

If you want 15 dots now you should use it like (same as your example)

pawn Код:

new
    dots = 15,
    Float: cX = 6.0, // center of circle
    Float: cY = 4.0, // center of circle
    Float: X = 6.0, // first point
    Float: Y = 1.0, // first point
    Float: angle = 360.0 / dots // split the circle in x (dots) pieces
;
while(dots--) { // crashes your server if dots < 0
    GetNextPointOnCircle(cX, cY, X, Y, angle);

    printf("%f %f", X, Y);
}

Go through the source code of this include, you will find your answer,
Source Code

Objectometry - Include Thread

If you are trying to place objects in a circular path, this include lets you do that.

[Write]

It dosen't move like that, it goes like;

Код:

{ strpack; '3x3x != 93c ab' 3x3x3 != 0 & != 12 }

You must find a destination to the size.

Thank you both for answers, I really appreciate your help, but I forgot to mention that I already done it
