[General] Angle between

[Aeroblyctos]

Hey,

How I make angle between East and South? And what about North and East?

Warcraft 3 angles are:

North: 90
East: 0
South: 180
West: 270

Get a random real between 270 and 360. 0 to 90 for north to east.

 

[Wietlol]

I dont really understand your question.

Angle is a real value between 0 and 360 that indeed starts to east and increases against the clock.

An angle to east is equal to 0 AND 360 as these are the same.
An angle to north is equal to 90.
An angle to west is equal to 180.
An angle to south is equal to 270.

If you want an angle to a point somewhere to the south-east, you have an angle pointing to 270 til 360 degrees.
415 degrees is exacly the middle.

Pointing north east is somewhere between 0 and 90 and 45 is the middle.


If you want the angle between the east of the map and the south of the map it could be a bit different.
If the map is a square, it is no big problem, but if it is not then you need something to determine it.
In GUI there is a function that can calculate the angle between 2 points.
I don't know how to get the size of the map because I haven't got an editor right now but that shouldnt be a problem.

This might have answered your question but I don't really know what you mean.

Doesn't seem to work. Northwest and southwest points bugs at the moment.

Here test map. All carrion swarms should shoot to the dark place(middle).

North: 90
East: 0
South: 180
West: 270

I'm sure this is not quite correct. IIRC North is 90°, right. But south is 270° for sure. And Probably West is 0°, and East 180°.

In wc3 everything is different.

 

[Wietlol]

In WC3:
E: 0*/360*
N: 90*
W: 180*
S: 270*

Go to the terrain editor and change direction of units and find out what I just said XD

I will take a look at the map right now. (Downloading /|\ )

 

[IcemanBo]

Ok, I also mixed up West/East. But tested now again, so...

North: 90°
East: 0°
South: 270°
West: 180°

So you only mixed up South/West.

Edit: Did not see your post above.

You switched north-west and south-west.
The trigger you need is this:
(degrees work fine)
(Only switch the reals in the random real part. Nothing more.)

In wc3 everything is different.

How?

Note: If it's above 360 it goes down to 0, but the value is still above 360. So 720 = 0, 540 = 180

Yup, angle + 2*k*pi

 

[Wietlol]

Im happy enough that WC3 doesnt use radians.

Yeah, indeed..

 

[edo494]

yet Jass does

 

[JustNrik]

How can North be 90º and West 270º? Fuck Logic.

Whatever.

0 and 360 - East - 0 and 2pi
45 - Northeast - pi/4
90 - North - pi/2
135 - Northwest 3pi/4
180 - West - pi
225 - Southwest - 5pi/4
270 - South - 3pi/2
315 - Southeast - 7pi/4

Just as bajaist posted

Multiply a degree with bj_DEGTORAD and vice versa (RADTODEG).

 

[Wietlol]

Well I havent seen radians so far in JASS.
I do use them in C# but I prefer degrees.

Unless you always use the functions that are there for locations then jass is always in radians. You may also use radtodeg and degtorad as mentioned above. They convert radians to and from degrees.

 

[Aeroblyctos]

Yes indeed guys. I got it to work.

Thanks a lot!
