Circular-styled orbit formula. Lil' help?

[BeTaGod-]

[GUI guys!]. So, i want to create some sort of formula that checks for the current position of X, wich will constantly circulate around Y, creating some sort of "bubble" with every loop. I am not sure if i explained it right, so here comes a fraking awesome artwork:

Pink dots represent the X variable points while the little cute black one in the centre represents the Y location. The draw's view is from above the Y point, BTW.

(Don't pay that much attention to the timer, ingame will be properly synchronized)

Besides, the X dots will be dummy units with a SFX attached to their chest, so with every new loop (that will make them circulate around the Y point) they will get a new flying height to give the look that the SFXs creates some sort of circle that closes around the Y location. Did i explain myself? While the X dots are smaller in the incredibly awesome picture, they will have a higher flying height around the Y point as well.

Any help? I am pretty sure this is NOT that difficult to achieve.

point1 = center thingy
loop integer from 0 to 3
-point2 = point1 offset by x towards (45*integer)
-move unit to point2
-remove point 2
remove point1

Store new x for next interval. x = x - i
Store new y for next interval. y = y + j

Very kind of you, but that won't make the units spin around the Y axis or to get a higher flying height.

are you trying to do something like THIS http://www.hiveworkshop.com/forums/...929/?prev=search=demon%20spinning&d=list&r=20
the whole thing is in gui and you can see what he did

I dunno that my spells were that much popular ^^

Except this, let's say you have a variable for the flying height of the pink points (on your schemas), let's name it H.

Basically H has some values you've defined in an initialisation trigger or in the cast trigger (or other).

Let's say that every 0.03 seconds we decreases the value from H for this, we make : H = H - x (x is a number)

And like this the height will decreases.

Now, in our present case, your variable is the Current Flying Height of your unit and so, you just need to Set the flying height of the unit to the Current Flying Height - x (some number)
And this should be periodic ^^


For the circle movement, there are multiple ways, in Demon Spinning (linked upper), i stored the actual angle of my unit and i changed this angle (by doing + X) periodically. It was kinda like what i've done for the height.
You can also use Cos and Sin with Coordonnates to simulate the circle from a Point (the Center) with a Distance (the Radius) and some value to have the turning speed.

• Set Point = (CIRCLE CENTER)
• Set Point3 = (Position of MyUnit)
• Set Point2 = (Point offset by ((300.00 x (Cos((1.50 + (Angle from Point3 to Point))))), (300.00 x (Sin((1.50 + (Angle from Point3 to Point)))))))
• Unit - Move MyUnit instantly to Point2
• Custom script: call RemoveLocation( udg_Point )
• Custom script: call RemoveLocation( udg_Point2 )
• Custom script: call RemoveLocation( udg_Point3 )

In that example, the Radius was 300 and the turning speed was 1.50.

The images you show have X as a vector yet X is usually a scalar component of a vector, please clarify that you are referring to a 2D vector as X.

Also what is getting checked? What do you mean by checking X?
