Spell-Caster behind the target

-Berz- · Jul 19, 2008

Hi!

I have this idea in my head, but i don't know how to set a condition.
It should go like this:

If (Facing of (Target unit of ability being cast)) Equal to ((Facing of (Triggering unit)) - (Random real number between 0.00 and 180.00))

I know its wrong, because it don't work D: (its just to see what i mean)

So if Triggering unit is behind the Target unit of ability being cast the actions should run, else not
(for exsample dota spell "backstab" from rikimaru, I only need a condition nothing else)

Thanks!

Here:

((Facing of (Target unit of ability being cast)) Greater than or equal to ((Facing of (Triggering unit)) - 180.00)) and ((Facing of (Target unit of ability being cast)) Less than or equal to ((Facing of (Triggering unit)) + 180.00))

This checks if the target is behind you.

((Facing of (Triggering Unit)) Greater than or equal to ((Facing of (Target unit of ability being cast)) - 180.00)) and ((Facing of (Triggering Unit)) Less than or equal to ((Facing of (Target unit of ability being cast)) + 180.00))

This checks if the you are behind your target.

-Berz- · Jul 19, 2008

thanks I'll try it out

edit: its not working right :S, actualy it happens every time i cast the spell, not only when i'm behind it.
Any other ideas?
edit2:

(Facing of (Triggering unit)) Greater than ((Facing of (Target unit of ability being cast)) - 120.00)

Ok this seems to work

redscores · Jul 19, 2008

Thats wrong, you can do it better, but you need 2 angles for it, so lets think, if the units facing is 270 degrees then + 180 is directly behind him, now if you check that the facing angle between the target and the caster is greater as (facing angle of caster +135) and smaller as (facing angle of caster + 225) degrees is just the 45 degrees behind the target possible, that would make it not so hard to hit the back but wont make it odd looking.

-Berz- · Jul 19, 2008

So how should i actually set it?
with two conditions +/-?

Edit:
I have another problem with windwalk +damage text becuse im using this and it dispays "0! and 380!" and it looks stupid...

Lol.
Checking facing angles

Check the facing angle and the angle between the positions of the two units.
SO you either do that in the actions, instead of doing so in the conditions(because of leaks).
P.s. If you do it in jass, that you can do it in the conditions

Any specific action condition i can use?(not in Jass)

spiwn · Jul 19, 2008

Set temp_point1= location of Triggering unit.
Set temp_point2= location of Attacking unit
Set a = angle between temp_point1 and temp_point2 (unnecessary line)
Set b = Facing angle of (triggering unit) (unnecessary line)
If ( b > Modulo(a +90,360) OR b<Modulo(a-90,360) )
I just wrote that, so it is neither jass nor GUI but I think you will get the idea.

Edited! Thanks to HINDYhat for the reminder.
P.s. I guess negative angles should be taken care of aswell.

HINDYhat · Jul 19, 2008

Be careful though, since Wc3 doesn't work with angles... so 370 != 10.

-Berz- · Jul 20, 2008

Now i made this, i didn't test it jet, I hope it works!

((Facing of (Attacking unit)) Greater ((Angle from TempLoc17 to TempLoc16) + (90.00 mod 360.00))) or ((Facing of (Attacking unit)) Less than ((Angle from TempLoc17 to TempLoc16) - (90.00 mod 360.00)))

Damn it still doesn't work right

and jeah some variables are useles, I couldn't use them in condition

spiwn · Jul 20, 2008

If ( b > Modulo(a +90,360) OR b<Modulo(a-90,360) )
You placed the mod at the wrong place.
You couldn't use the variables because they should be reals, not integers(temp_real).
" Animation - Play (Attacking unit)'s slam animation
Set TempLoc16 = (Position of (Attacked unit)) "
Last line unnecessary(maybe even causes a leak).
You also need to remove temploc17.
You can use triggering unit instead of attacking unit.
P.s. I wonder why you need seventeen templocs.

Huurka · Jul 20, 2008

Yeah. You should be able to put them in locals.

So 17 templocs is too much

-Berz- · Jul 20, 2008

I'm making a spell pack(in my signature, this is about 10/11 spell)

Edit: now it doesn't work at all :S

Set TempLoc16 = (Position of (Attacking unit))
Set TempLoc17 = (Position of (Attacked unit))
Set AngleVar = (Angle from TempLoc16 to TempLoc17)
Set AngleVar01 = (Facing of (Attacking unit))
---------------------------------------------------
(AngleVar01 Greater than (AngleVar + (90.00 mod 360.00))) or (AngleVar01 Less than (AngleVar - (90.00 mod 360.00)))

spiwn · Jul 20, 2008

(AngleVar01 Greater than ((AngleVar + 90.00) mod 360.00)) or (AngleVar01 Less than ((AngleVar - 90.00) mod 360.00))

But as I said, (AngleVar - 90.00) can be negative. And AngleVar01 is always > 0.

-Berz- · Jul 20, 2008

I'll try it out.

Edit:it still not work, it only works when the attacked unit looks up in the map

(AngleVar01 Greater than ((AngleVar + 90.00) mod 360.00)) or (AngleVar01 Less than ((AngleVar - 90.00) mod 360.00))

Man, this evil line is leading me insane!

spiwn · Jul 20, 2008

Figures.
Set AngleVar = (Integer((Angle from TempLoc17 to TempLoc16)))
Should be:
Set AngleVar = (Integer((Angle from TempLoc16 to TempLoc17)))

HINDYhat · Jul 20, 2008

First Jass function I've ever made. Seriously, this was the FIRST working function I had written. Curious coincidence this is exactly what you need.

Returns a boolean, to see if a unit (Who) is behind another unit (BehindWho).

Use the Angle variable in the function calling for a "more or less" value. Never set this value to 0.0, the function will almost never return true... The function will check if a unit is facing in the same direction as another one, more or less the Angle value.

JASS:

function IsUnitBehind takes unit Who, unit BehindWho, real Angle returns boolean
    local real d=GetUnitFacing(Who)-GetUnitFacing(BehindWho)
    if d>=180.0 then
        set d=d-360
    elseif d<=-180.0 then
        set d=d+360
    endif
    return (d<=Angle and d>=-Angle)
endfunction

Eccho · Jul 20, 2008

I have a post similiar to this. But since I have not figured out what you want to do with those angles you better take a look yourself

I hope its on the right track

Doesn't work right

even if i use unit group...

Eccho · Jul 20, 2008

well no, since the angle is not right I assume. What is happening if you change
AngleVar Less than ((Facing of (Attacking unit)) + 45.00)
to
AngleVar Less than ((Facing of (Attacking unit)) + 90.00) and respictively
AngleVar Less than ((Facing of (Attacking unit)) - 90.00)?

Also, maybe its the floating text? Try a game message.

If I get it right? You want a "backstab" attack if the unit breaks the stealth?

Yes something like that.

@HINDYhat
Using only unit facings ...
So you make sure, the both units are facing almost the same way, but you do not check which unit is behind which one.

Hm.. let me see from the inside... Ill do the trigger too hm..

Edit: nvm

-Berz- · Jul 21, 2008

I have another problem is there a condition/action anything that would sound like
"Matching unit is currently attacked by triggering unit"?
Its for my new spell where hero is attacking unit, than it cast(taunt(no target spell)), than it search for the unit in unit group that is "Matching unit is currently attacked by triggering unit"
I just ask if its anything like that, or custom script, just let me know if it is (and tell me where) other i'll manage myself.
THX!

Eccho · Jul 21, 2008

I think it has to be done with jass. It depends on how many who can have it at once though. But no that "pre" specific script does not exist

The idea would be I think, in MPI (player arrays)

AttackSimulation
Events
- Unit - Unit is attacked
Conditions
- Unit-type of attacking unit is equal to "your choice"
Actions
- Set CurrentTarget[Player number of owner of attacking unit] = Triggering unit

And then

TauntEffect
Events
- Unit - A unit starts the effect of an ability
Conditions
- Ability being cast is equal to "TauntChoice"
Actions
- //This part is only used if you want to check if the last target is within a specific range of the caster
- Set TempPointA = Position of Triggering Unit
- Set TempPointB = Position of CurrentTarget[Player number of owner of triggering unit]
- // ---
- If actions - CurrentTarget[Player number of owner of triggering unit] is alive equal to true and distance between TempPointA and TempPointB is less than or equal to 400 (as example) then - actions
  - //Do Actions regarding last attacked unit of triggering unit, example
  - Unit - Issue triggering unit to attack CurrentTarget[Player number of owner of triggering unit]
- else - actions
Custom script - call RemoveLocation( udg_TempPointA )
Custom script - call RemoveLocation( udg_TempPointB )

Hm well, Im sorry for the incorrect trigger tagging, I do not have we at the moment.
hope you understood the whole idea.

Thanks, i will rethink you trigger a few times, and than i'll see what happens.
