# X,Y,Z Offset?

Hey guys, simple enough math question here. If I have an initial x, y, z point, how do I find the x, y, z coordinates of a point c distance away?

Also, how would I implement this into the trigger editor? For a XY scenario, I could just use (point offset by distance towards angle), but the three dimension support is surprisingly poor in the galaxy editor.

If it helps, I already created a function within the editor for determining the distance between two three dimensional points.

##### Creating with the power of rage
Try this

Trigger:
• XYZ Offset
• Options: Function
• Return Type: (None)
• Parameters
• fromX = 0.0 &lt;Real&gt;
• fromY = 0.0 &lt;Real&gt;
• fromZ = 0.0 &lt;Real&gt;
• d = 0.0 &lt;Real&gt;
• h = 0.0 &lt;Real&gt;
• XYangle = 0.0 &lt;Real&gt;
• Grammar Text: XYZ Offset(fromX, fromY, fromZ, d, h, XYangle)
• Hint Text: (None)
• Custom Script Code
• Local Variables
• XY = No Point &lt;Point&gt;
• RealXYdistance = 0.0 &lt;Real&gt;
• X = 0.0 &lt;Real&gt;
• Y = 0.0 &lt;Real&gt;
• Z = 0.0 &lt;Real&gt;
• Actions
• General - If (Conditions) then do (Actions) else do (Actions)
• If
• h &lt;= d
• Then
• Variable - Set RealXYdistance = (Square root(((d * d) - (h * h))))
• Variable - Set XY = ((Point(fromX, fromY)) offset by RealXYdistance towards XYangle degrees)
• Variable - Set X = (X of XY)
• Variable - Set Y = (Y of XY)
• Variable - Set Z = (fromZ + h)
• Else

Just give it initial XYZ [fromX, fromY, fromZ] , how higher (or lower) you want the point to go [h], what distance [d], and to what angle on the XY plane [XYangle].

I have a problem with over clarifying things, but better safe than sorry
It should work but it's untested, so here's the sketch for (what I think is) the solution anyway.

EDIT: Optionally, if you want, I can make one which instead of height takes a second angle.

Ah thanks guys. I actually solved it myself through a LONG time of experimentation. However, here's what I'm trying to do. My initial intention was to detect where a unit is hit by a passing projectile and create an actor to show where the 'impact' occurred on the character model. It works perfectly, but I've hit a small snag.

Here's my function. : Your suggestion seemed simpler and easier on the computer's processor and RAM, so this is what I'm using now:
Code:
``````Point With XYZ Polar Offset
Options: Function
Return Type: Point
Parameters
Point = No Point <Point>
Offset = 0.0 <Real>
XY Angle = 0.0 <Real>
Z Angle = 0.0 <Real>
Grammar Text: (Point) offset by (Offset) at XY angle (XY Angle) and Z angle (Z Angle)
Hint Text: (None)
Custom Script Code
Local Variables
End X = 0.0 <Real>
End Y = 0.0 <Real>
End Z = 0.0 <Real>
Actions
Variable - Set End X = ((X of Point) + (Offset * ((Cos(XY Angle)) * (Cos(Z Angle)))))
Variable - Set End Y = ((Y of Point) + (Offset * ((Sin(XY Angle)) * (Cos(Z Angle)))))
Variable - Set End Z = ((Height of Point) + (Offset * (Sin(Z Angle))))
General - Return (Point(End X, End Y, End Z))``````
Here's how I calculate the Z axis angle (pitch):

Code:
``````Angle Between Points on Z Axis
Options: Function
Return Type: Real
Parameters
Point1 = (Position of (Triggering unit)) <Point>
Point2 = (Position of (Triggering unit)) <Point>
Grammar Text: Angle Between (Point1) and (Point2)
Hint Text: (None)
Custom Script Code
Local Variables
Pitch = 0.0 <Real[1]>
Actions
Variable - Set Pitch[0] = (Distance between Point1 and Point2)
Variable - Set Pitch[1] = ((Height of Point1) - (Height of Point2))
General - Return (Atan((Pitch[1] / Pitch[0])))``````
There's a problem that occurs somewhere in the Offset trigger, because every single effect is being displayed near the centre of the sphere. Basically, the trigger is returning 0 values for X and Y (or just much lower values than it should have). Why would that be?

Both my old, more complex, homemade version and this simpler one Sgqvur referred me to have the same problem.

: GAH nvm thanks guys. I was looking at the third post on that page you referred me to, not the second. The second works flawlessly...should have known better than to think Aceheart was wrong.

It would suck to spend 400\$ on a system that doesn't have the capability you need
• jonas:
and it will probably take a couple of tries to get the settings right
• Varine:
It would but I can also just make sure I can return them. The system I have works, it's pretty straightforward and I tested it with a camera I have. All it really is is a little cartridge that holds the transparency film and a white light source behind it that projects the image into the lens
• Varine:
I'll have to fuck with the light a bit and try some different lighting methods to get color accuracy, but I have IT8 targets for that
+1
• The Helper:
get that color accuracy
• Varine:
They're really helpful for calibrating things because I'm really colorblind, so I'm not great at doing it by eye

• Varine:
Well the long, slow slog of winter has officially begun here
• Varine:
I have a bunch of community service I have to do, and I have a feeling there will be a lot of snow shoveling involved now
• The Helper:
don't know why people choose to live in that kind of weather
• Varine:
Well
• Varine:
My job is here
• Varine:
I was born here man I didn't choose shit
• Varine:
And also, I keep moving away and it doesn't get any better. I moved to San Antonio and shit froze there AND we had blackouts
• tom_mai78101:
I'm back, suffering from severe jet lag.
• The Helper:
Cold is following your ass around Varine - I just dont think I could handle a snowy winter.
• The Helper:
Welcome Back Tom!
• The Helper:
I hear that taking a Melatonin around your normal bedtime can really fix jet lag
• tom_mai78101:
Yeah, I also heard about that as well. I think I'm good. I'm just lucky it's the weekend so I have some time to readjust.

• Varine:
It was a fucking blizzard today, shoveling was an effort in futility.
• Varine:
Melatonin gives me nightmares
• Varine:
They had me shoveling out the parking lot for the jail. Fucking pointless, they need a blow.
• Varine:
Well they gave me a snow blower but it was too wet to do much with with other than compact everything. Oh well, the cop cars can get into there now when they arrest people I guess
