Can you tilt the axis?

[Foresector]

This is kind of complicated to explain so yeah..

I was wondering if there was anyway to tilt the axis on any angle you want.
Being that the default Y axis in Warcraft goes vertically and X axis goes horizontally.
If anyone wonders what axis are used for, you use them for co ordinates to pick certain points on the map, like 40, 60 would be like 40 across and 60 up from the center.

 

[waaaks!]

i think u cannot tilt the axis in wc3, im pretty sure that the default view has the x and y axis default also

 

[Foresector]

Oh, that's a pity..

In that case, does anyone have suggestions on maybe creating your own axis within a trigger so that you can pick out certain points?

I was thinking of one with 2 lines of dummy units but then I wouldn't know how to pick out points in relation to them

What are you trying to do here?

 

[Gojhin]

yeah i really don't think you're explaining your problem very well. try rephrasing it so we can understand your question.

 

[Foresector]

, Quite simple really.

I'm trying to create a shockwavy ability except I don't want it to move in a straight line.

I'm using a basic calculus function (Y=Cosine X) to get the shockwave to move in sequential curves.

This basically means, that the horizontal movement is at regular pace, while the vertical movement starts from top, goes down then back up, repeating every 360 degrees.

This function requires co ordinates that are retrieved from the default axis used in WC3.

Unfortunately, this means that the spell will only ever go from left to right at a perfect 90 degree angle because of the fact that I can't tilt the default axis.

I was wondering if you could simulate a tiltable axis made up of maybe dummy units, and using some type of function to replicate X and Y points, that way you could send this curving shockwave at any angle.

That's more of a problem description


Starting with the unit's activity, get the following:

Px = X of Casting unit,
Py = Y of Casting unit,
A = Angle from Position of Caster to Target point of ability

Enter some loop for your calculations:

X = going from <start> to <more> (yes, the "normal" left to right only),
Y = some function result involving X

And let it happen on the map with:
Xnew = Px + X * cos(A) + Y * sin(A)
Ynew = Py + Y * cos(A) - X * sin(A)

Which rotates the originally calculated point (X;Y) according to the casting direction A, with (Px,Py) as origin.


Good luck

Sorry once again

I tried using that formula and came up with this..

    Events
        Unit - A unit Starts the effect of an ability
    Conditions
        (Ability being cast) Equal to Spiral 
    Actions
        Set PX = (X of (Position of (Casting unit)))
        Set PY = (Y of (Position of (Casting unit)))
        Set Angle = (Angle from (Position of (Casting unit)) to (Target point of ability being cast))
        Unit - Create 1 Shockwave for (Owner of (Casting unit)) at (Position of (Casting unit)) facing Default building facing degrees
        For each (Integer A) from 1 to 360, do (Actions)
            Loop - Actions
                Set X = ((X of (Position of (Last created unit))) + 1.00)
                Set Y = (1.00 x (Cos(X)))
                Set NewX = ((PX + X) x (((Cos(Angle)) + Y) x (Sin(Angle))))
                Set NewY = ((PY + Y) x (((Cos(Angle)) - X) x (Sin(Angle))))
                Unit - Move (Last created unit) instantly to ((Position of (Casting unit)) offset by (NewX, NewY))
                Wait 0.01 seconds

But for some reason the shockwave just keeps moving in the corners of an imaginary triangle.

 

[AceHart]

Well, the (s and )s are slightly off...

> Px + X * cos(A) + Y * sin(A)

The 3 blocks added together here are
"Px", "X * cos(A)" and "Y * sin(A)"

 

[Foresector]

Um sorry to be such a hassle

I've been working at this for quite a while now and it still doesn't seem to work.

Is this how it should work?

Melee Initialization
    Events
        Unit - A unit Starts the effect of an ability
    Conditions
        (Ability being cast) Equal to Spiral 
    Actions
        Set PX = (X of (Position of (Casting unit)))
        Set PY = (Y of (Position of (Casting unit)))
        Set Angle = (Angle from (Position of (Casting unit)) to (Target point of ability being cast))
        Unit - Create 1 Shockwave for (Owner of (Casting unit)) at (Position of (Casting unit)) facing (Facing of (Triggering unit)) degrees
        Set Shockwave = (Last created unit)
        Trigger - Turn on Axis Tilt <gen>
        Wait 3.00 seconds
        Trigger - Turn off Axis Tilt <gen>

Axis Tilt
    Events
        Time - Every 0.01 seconds of game time
    Conditions
    Actions
        Set X = ((X of (Position of Shockwave)) + 5.00)
        Set Y = ((100.00 x (Cos((X of (Position of Shockwave))))) + PY)
        Set NewX = (PX + ((X x (Cos(Angle))) + (Y x (Sin(Angle)))))
        Set NewY = (PY + ((Y x (Cos(Angle))) - (X x (Sin(Angle)))))
        Unit - Move Shockwave instantly to (Point(NewX, NewY))

 

[AceHart]

> Set Y = ((100.00 x (Cos((X of (Position of Shockwave))))) + PY)

What is that supposed to do?

It also doesn't look like anything mentioned as "basic calculus function" in post #6, or used in #8.

 

[Foresector]

Oh thanks for the help again Acehart I would be so lost without you

Set Y = ((100.00 x (Cos((X of (Position of Shockwave))))) + PY)

The basic calculus function is Cos X
The times 100 is because 5 across on the x axis is like hardly a millimeter on the screen so I use bigger numbers.
The PY is to compensate for where the shockwave starts on the Y axis, otherwise the shockwave would instantly be brought to the middle
