Circle Generator

[toddnollan]

This returns points (x,y) on a circle, given the quantity of points (Signal Q), Diameter of the circle (Signal C), and the index of which point to return (Signal i).
I designed it for use with AAI things, but it does not require AAI and uses only vanilla signals.
The circle is probably not mathematically precise, but it does pretty well. The return points are always centered on 0,0. To change that, add the x,y offset to them with a constant combinator.
It counts clockwise, 0 being at the absolute bottom.
If Index is higher than Quantity, it will simply treat it as a restart of the loop; for instance, with a quantity of 7, an index of 9 will be interpreted as 2.
A Quantity above 1000 will probably cause problems and freak out, so keep it below that.

This uses no loops, and will handle the Index changing every tick.

The blueprint has the first combinator set to a Quantity of 50 and a radius of 35, with an index of 0. These are the values to change, or input.

This is a simple setup, with a loop attached to the input to increment the Index, and an AAI Zone placer with constant combinator attached to the output to visualize the output.


Output of D=20, Q=17, and a full increment through the Index.


This shows a full circle of with a Diameter of 35 and a Quantity of 50. This is (almost) aligned with a gun turret to show how nice of a circle it is.


As an example of what a single output would be, the blue circle is what returns for the above settings, but an index of five.

BluePrint of Concrete circle does the same thing to measure the the gun radius or darken the opaque settings of the Alpha settings
