# How do I assign new user coordinates?

• 6 posts
• I want to assign users to coordinates on a map as they create an account.

Earlier account creators will be near the middle.

Later accounts and re-spawns will be placed at the periphery, so that the players are placed in an ever widening circle.

• Simple solution off the top of my head - if you're keeping track of the user accounts, have their spawn location coordinates multiplied by their chronological order number.

Interesting... thanks.

But, i don't think that accomplishes what I'm trying to do.

• Around a middle (0,0) that is a circle.

Cartesian for a circle =

x= a * cos(angle)

y= a * sin(angle)

So, if you wanna place them on a circle around the middle(0,0), just add a certain degrees to angle each time an account is created, and you know x and y. How much you want to add depends on the needed space. Say the space needed is a circle with diameter b.

Then the first circle describing the first round around the middle must have at least radius a = b*6 (i think)

Now you add 360/ (round((pi*2*a) / b)) every time an account registers to angle.

When that circle is full, you add b to a.

And again you add 360/ (round((pi*2*b) / d)) every time an account registers, until again also that circle is full.

When that circle is full, you add b to a. ... and so on

But, that is kinda mimicking a spiral.

Cartesian for a simple spiral =

x= (a + (b*angle)) * (cos(angle))

y= (a + (b*angle)) * (sin(angle))

a kinda says where you start from the middle, while b controls the distance between successive turnings…

Now again, just add a value to angle, and you know x and y.

I just dont know how much degrees in this case. Guess you got to find that yourself or ask a smarter dude then me.

• But then again. Say we start with 1 square in the middle. And we want to seamless add squares in a spiralling way. like 1 right, 1 down, 2 left, 2 up, 3 right, 3 down, .......... and so on.

• Thanks for your time 99Instances2Go. I was on this trail too, thanks to very old Trigonometry books, and Stack Overflow.
