[Trigger] Offset points for an octagon?

[FriXionX]

Can someone give the offset points for an octagon around a unit? Thx in advance.

Octa = 8 right?

function octagon takes real StartX, real StartY, real Length returns nothing
    local integer i = 0
    loop
        exitwhen i > 7
        set Location[i] = Location(StartX + Length * Cos((360/8)*i),StartY + Length * Sin((360/8)*i))
        set i = i + 1
    endloop
endfunction

Thx, but how would i do that in GUI? Or can i copy/paste that somehow in GUI >.>

 

[Yixx]

• For each (Integer A) from 0 to 7 do Multiple Actions
  • Actions
    • Custom script: set udg_Location[bj_forLoopIndexA] = Location(udg_StartX + udg_Length * Cos(((360/8)*bj_forLoopIndexA)*bj_DEGTORAD),udg_StartY + udg_Length * Sin(((360/8)*bj_forLoopIndexA)*bj_DEGTORAD))

Thx so much, +rep. But what i wanted was to set variables to those points, is that what this does? I dont really understand it.

 

[Yixx]

Yes it sets the points,
Create a variable with a name and type Point array
in the Custom script, change 'udg_Location[bj_forLoopIndexA]' with 'udg_YOURNAME[bj_forLoopIndexA]'
udg_Location[0] is the most right point, Location[2] is the lowest point, Location[4] is the most left point, and Location[6] is the upper point, the rest is in between,, so this is how you can see it:
Location[0] = East
Location[1] = SouthEast
Location[2] = South
Location[3] = SouthWest
Location[4] = West
Location[5] = NorthWest
Location[6] = North
Location[7] = NorthEast

You forgot to convert the angles to radians.
45 * bj_DEGTORAD * i

 

[Yixx]

Damnit, >.>,, you are totally right,,
I am too used to working with Degrees,,

Updated, converted to Radians now,,

 

[FriXionX]

Thx Guys. +rep

 

[FriXionX]

It doesnt work. It gives me 4 errors in the same line >.>... print screen coming up.

and my trigger is:

• Custom script: set udg_NeedlesSummonLocation[bj_forLoopIndexA] = Location(udg_StartX + udg_Length * Cos(((360/8)*bj_forLoopIndexA)*bj_DEGTORAD),udg_StartY + udg_Length * Sin(((360/8)*bj_forLoopIndexA)*bj_DEGTORAD))

which i think is what you put?

 

[Reaper2008]

This requires 4 globals, a location (Location), a real (StartX), a real (Length), and a real (StartY) .

 

[FriXionX]

Thx. i made them all - but i still get a compile error. Undeclared variable bj_forLoopIndexA

 

[Megafyr]

Try replacing it with bj_forLoopAIndex.

 

[Yixx]

Ok, i made a typo, it should be 'bj_forLoopAIndex' instead of 'bj_forLoopIndexA' , sorry,,

If you want any polygon just use 360 : (Number of the polygons side), It is very simple, You want octagon, 360 : 8 = 45
If you Want the eight points just set

Octagon[1] = 45
Octagon[2] = 90
Octagon[3] = 135
Octagon.... = ....
Octagon is a variable real array

 

[Yixx]

Wow, great, then you have the angle at which every point is. If you look very well you can see that in my function, you dont calculate the angles, but the Locations already, so no need of that real array, only a point array,,
