Hashtable help

[LightChaosma]

ok, befor i start, this is the FIRST time i am using hashtables, and the first time im working with knockback.

scenario:
i have a tower that has a normal attack that has knowckback. the knockback is working like a charm.
i'm using a hashtable for this knockback.
the problem:
once the knockbak is done, the targeted unit, has lost his order, how do i save the order of that unit into a hashtable.

maybe this makes it easier:
the order of the targeted unit is always right click a point, so move to a point.

you can use the Hashtable - Store String function to store the current order of your towers' target and then, after the kbk is done order that unit to ... do what it was ordered to before, also, you can store the point in the hashtable

sorry i cant tell you how to make it via hash tables cause i dont know either but maybe i can tell you an other way to do it.

i guess you are using 'unit - move unit (instantly)' to knock the unit back. however you can use 'custom script: call SetUnitX/Y' to move the unit to another position without losing its order. this way you wouldnt need to save it somewhere.
if you dislike the fact the unit would still move towards its position while being knockbacked you might as well change its movement speed for the duration of the knockback to 1.00 or even 0.00.
i dont know whether it would be worth doing it this way because, as i said before, i dont know hashtables myself.

@Jackal
that didnt work..
i now have a trigger 3, that stores the targeted point of the unit in a hashtable each time it gets an order (and is not being pushed back), and this works fine

@accname
that sounds nice, if i can get that to work it would make things less complicated...
but how would i send the unit towards its current position +20, ofset by an anlge with that. would this work?

(freehand)

set tempint[1] = X of point temppoint[1]
set tempint[2] = Y of point temppoint[2]
custom script: call SetUnit (tempint[1]/tempint[2])

(i dont know jass)

 

[jackall]

it would look somewhat like this

   set tempInt[1] = GetLocationX(loc)
  set tempInt[2] = GetLocationY(loc)
    call SetUnitX(GetenumUnit(),tempInt[1])
    call SetUnitY(GetenumUnit(),tempInt[2])

pff... looks like it doesnt count the spaces in first line

 

[LightChaosma]

how would the code know wich unit to move in the code above?

(picked unit) in this case

 

[jackall]

GetEnumUnit() refers to picked unit
GetFilterUnit() refers to mathing unit(i think)
notice the change i made to the above post... i dont have we atm and i forgot all variables you have to give SetUnitX/Y

 

[LightChaosma]

i have this now, and i cant even test it due to errors...

trust me, there is a picked unit, no need for you guys to see the rest it wont help you at all

• Then - Actions

  • Custom script: call RemoveLocation (udg_temppoint[2])

 

[jackall]

• Custom script: call SetUnitY(GetenumUnit(),tempreal[2])

shouldn't it be GetEnumUnit()?

 

[LightChaosma]

it gives errors on both X and Y, and X has a capital letter E

 

[jackall]

it gives errors on both X and Y, and X has a capital letter E

well, SetUnitX (, you left a space there

 

[LightChaosma]

call SetUnitX(GetEnumUnit(),tempreal[1])
call SetUnitY(GetEnumUnit(), tempint[2])

yes, i'm aware of the space in the Y, and the int and real... i've tested all combination of spaces, ints and reals

 

[jackall]

that should work...

 

[LightChaosma]

it keeps on giving the same error....
i made my own piece of jass, and it still doesnt work... (my very first piece of jass)

in my map heade i made this:

function MoveUnit takes location l, unit u returns nothing
    local real x=GetLocationX(l)
    local real y=GetLocationX(l)
    call SetUnitX(u,x)
    call SetUnitY(u,y)
endfunction

and in my trigger this command:

• Custom script: call MoveUnit(GetEnumUnit(), temppoint[2])

it keeps expecting a name...

 

[saw792]

temppoint[2] -> udg_temppoint[2]
etc

 

[LightChaosma]

still doesnt work...
i expect you to want the whole trigger now, so here it is

          • If - Conditions
            • (Load 1 of (Key (Picked unit)) from PushTable) Greater than 0
          • Then - Actions
            • Set tempint[1] = 20
            • Set temppoint[1] = (Position of (Picked unit))
            • Set temppoint[2] = (temppoint[1] offset by (Real(tempint[1])) towards (Load 2 of (Key (Picked unit)) from PushTable) degrees)
            • Custom script: call MoveUnit(GetEnumUnit(), udg_ temppoint[2])
            • Hashtable - Save ((Load 1 of (Key (Picked unit)) from PushTable) - tempint[1]) as 1 of (Key (Picked unit)) in PushTable

[saw792]

The error is on the line above, it's udg_temppoint[2] not udg_ temppoint[2].

 

[LightChaosma]

didnt even see that space there... but still doesnt work...

in the compiler it says the error is in the hashtable line afterwards... that the location is wrong, but when i disable the custom script, it all works...

Custom script:   call MoveUnit(GetEnumUnit(), udg_temppoint[2])

 

[saw792]

Your function takes location, then unit. You input unit, then location.

 

[LightChaosma]

thx, that did it

but now the second part... does JASS implement X and Y diffrently than the GUI?

when the trigger is fired, thus a unit needs to be knockbacked, the unit first is transported to a location about 45 degrees underneath the center(see drawing), and then it is knocbacked properly...

     O          
               
               
   X

O is the center, X is where the unit shows up

when i use move unit(instantly) facing point in the GUI, it doesnt do that
