[Trigger] Explain to me please

[Arusar]

• Unit - Move F_Archer instantly to (Position of F_Archer), facing ((Facing of F_Archer) + 18.00) degrees

can u draw 4 me..? and what's that mean..?

 

[Avator]

It means that F_Archer rotates 18 degrees to the left.

 

[doom_sheep]

theres a trigger that just rotates units Oo

 

[Avator]

Exactly, so I don't know why someone would make it more dificult then it is.

Who gave you that command line?

 

[DarkAngelAzazel]

I hope this explains it:

 

[Kingz]

Just use:

• Unit - make unit face *x* angle

*x* may be like: x+y or x-y or even more complicated.

Where - means rotating the unit right and + rotating the unit left, just like Avator and DarkAngeAzazel pointed out.

 

[Arusar]

so that's mean the unit facing to left 18 deg....how if I want the unit rotate to right...?

btw thanks for helping me +rep

but one more question...

u know Rikimaru backstab at DOTA...
what the command or condition or something else
(GUI please not JASS cause I'm NOOOBB in JASS)
if attacking unit attack the attacked unit from behind it will deal bonus damage

 

[Kingz]

You could check for the facing angles like:

• Events - Unit is attacked
• Condition - Attacking unit has Backstab ability
• Actions
  • - If facing of attacked unit equal to (facing angle of attacking unit + 180)
    • -Then
      • -Cause attacking unit to deal *x* damage to attacked unit

Should work but the angle is pretty strict, and I never actualy made angle based spells so you should either make a new thread concerning the spell or try to make it yourself if this ain't what you need.

 

[Arusar]

thank's i'll try it

 

[darkrider]

actually... that is not gonna work coz the unit must be facing exactly to that position(which will rarely happen)... i think that you want something like this

• Events
  • Unit - A unit Is attacked
• Conditions
  • ((Facing of (Attacked unit)) Greater than or equal to ((Facing of (Attacking unit)) - 52.50)) and ((Facing of (Attacked unit)) Less than or equal to ((Facing of (Attacking unit)) + 52.50))
• Actions
  • Set next = your actions here

that will make the trigger to fire the actions if the attacked unit is facing the facing of the attacking unit -52º and +52º

if you need further explanation ask me here ^^

Where - means rotating the unit right and + rotating the unit left, just like Avator and DarkAngeAzazel pointed out.

Wrong. It is clockwise(-) and counterclockwise(+).

[Arusar]

ic" i'll try it

 

[Eleandor]

Wrong. It is clockwise(-) and counterclockwise(+).
--donut3.5--

hmm...

Isn't "rotating the unit right" clockwise, and thus - ?

I mean, you're right that clockwise is negative, but eh... isn't that exactly what he said?

 

[KYTON]

About the attack system. It has some bugs:

If the attacking unit has the facing angle of 1 and the facing angle of the attacked unit is 359, it will not deal the damage, because Warcraft will think it is comparing two reals while you are actually comparing angles. Let me explain:

The attacked unit's facing angle is 1
The attacking unit's facing angle is 359

Thus it will check:

Is 1 Greater than, or equal to 359 - 52.5 which it is not


So what you should do is a lot more complex

I use 5 real variables but you can use less, but it is harder to explain using less.

Facing1
Facing2
AngleClockwise
AngleAntiClockwise
Differance

Okay.
Firstly I set the variables.

set Facing1=((Facing of (Attacked unit))
set Facing2=((Facing of (Attacking unit))



// Here I'm just calculating the differance between the angles
set AngleClockwise=Facing1-Facing2
set AngleAntiClockwise=(Facing1+360)-Facing2


if AngleClockwise is less than 0 then
set AngleClockwise=AngleClockwise*-1 // If the angle is negative this makes it positive
endif

if AngleAntiClockwise is less than 0 then
set AngleAntiClockwise=AngleAntiClockwise*-1 // If the angle is negative this makes it positive
endif

// Now Finnally

if AngleAntiClockwise is greater than AngleClockwise then
set Differance=AngleClockwise
else
set Differance=AngleAntiClockwise
endif


// This entire piece of code finds the differance between angles, now you can just add

if Differance is less than X then

// Replace X with a number between 1-90 degrees
//X based on how easely you should be able to have the bonus damage. I prefer 45 degrees


// Your damge actions are placed here ->


endif

 

[darkrider]

mmm... ive never thought about that... thy for finding that bug (actually i have a spell that works that way ) +rep for the solution (even mine doesnt count yet :/)

 

[spiwn]

1 is not equal to 359 ... it may be equal to 361 though.
Far simpler way to do this is by using the modulo function.
I will replay the situation from above:

Facing1
Facing2


set Facing1 = Facing angle of attacking unit
set Facing2 = Facing angle of attacked unit

if( Modulo Real(Facing2 + 120, 360) < Facing 1 and Modulo Real(Facing2 + 240, 360) < Facing 2)
//the unit is attacking from behind, do stuff
endif

Isn't "rotating the unit right" clockwise, and thus - ?

I mean, you're right that clockwise is negative, but eh... isn't that exactly what he said?

No. Think about what happens when you pass the 180 degree mark. Circles are completely different than lines, you can't go left or right forever. Eventually, you have to come back around the other way. Once you get past 180 degrees, you add to go right and subtract to go left, yet from 0 to 180, you add to go left, and subtract to go right. Using clockwise and counterclockwise is much better terminology to use.

[Arusar]

I say it many times ok i'll try it

if work +rep

but i try it later

coz my comp has been broken

Edit:wait" 1 more question.... what is offset

ex:create 1 "unit" at position of "unit" offset by xx facing xx degree

 

[Kingz]

Example:
Create 1 unit at Position of *any* unit offset by *x* towards *y* degrees.

This will create a unit At Position of a unit 100 range points toward some angle.
Or:
Unit create 1 unit at Position of *any* unit offset by x,y

This will create a unit At position of a unit moved by x(left,right) and y(up,down).

This works for any point/location not just Position of unit.
Hope this helped.
