Show Tower Range

[vibon]

A trigger to make the range of a tower visible..

I have seen some other places.. But i really dident get the right answar..
Help?

 

[Adiktuz]

make the range visible as in when you select a tower then a circle that encloses its range will be shown?

 

[vibon]

Yes, exactly..
Trigger exsample?

Hm, you could set the point value of the unit to the range.
Or you could set some variables in a table.

Well, I'll try to explain both of them, but they're basically the same ^^
Either way, you need to create a "show range"-ability and a dummy unit (special effect, no shadow, abilities: locust, invulnerable, disable attack, doesn't show on minimap).

Point Value:

Show Range

• Show Range
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Range
  • Actions
    • Set loc[1] = (Position of (Triggering unit))
    • For each (Integer LoopInt) from 1 to 36, do (Actions)
      • Loop - Actions
        • Set loc[2] = (loc[1] offset by (Real((Point-value of (Unit-type of (Triggering unit))))) towards (10.00 x (Real(LoopInt))) degrees)
        • Unit - Create 1 Range Dummy for (Triggering player) at loc[2] facing Default building facing degrees
        • Unit - Add a 5.00 second Generic expiration timer to (Last created unit)
        • Custom script: call RemoveLocation(udg_loc[2])
    • Custom script: call RemoveLocation(udg_loc[1])

That was easy, lol
Ehh... this just creates 36 dummy units in a circle around the caster with as offset the point value ( = range)

Simple Table: (point value isn't always an option)

Init Variables

• Init
  • Events
    • Map initialization
  • Conditions
  • Actions
    • Set RangeInt = (RangeInt + 1)
    • Set RangeType[RangeInt] = Peasant
    • Set Range[RangeInt] = 200.00
    • Set RangeInt = (RangeInt + 1)
    • Set RangeType[RangeInt] = Footman
    • Set Range[RangeInt] = 800.00
    • Set RangeInt = (RangeInt + 1)
    • Set RangeType[RangeInt] = Knight
    • Set Range[RangeInt] = 600.00

Show Range

• Show Range
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Animate Dead
  • Actions
    • Set loc[1] = (Position of (Triggering unit))
    • For each (Integer LoopInt) from 1 to RangeInt, do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Unit-type of (Triggering unit)) Equal to RangeType[LoopInt]
          • Then - Actions
            • Set TempReal = Range[LoopInt]
          • Else - Actions
    • For each (Integer LoopInt) from 1 to 36, do (Actions)
      • Loop - Actions
        • Set loc[2] = (loc[1] offset by TempReal towards (10.00 x (Real(LoopInt))) degrees)
        • Unit - Create 1 Footman for (Triggering player) at loc[2] facing Default building facing degrees
        • Unit - Add a 5.00 second Generic expiration timer to (Last created unit)
        • Custom script: call RemoveLocation(udg_loc[2])
    • Custom script: call RemoveLocation(udg_loc[1])

Set all variables in the init variable-trigger like I've done it.

I didn't test this, but it seems right... if it doesn't work, please tell me the exact problem.

Of course, you can change the amount of dummies spawned :/

Hmm.. Cant you do it this way:


White circle = Range

 

[ap0calypse]

Being picky now, are we? D:

Well, I've looked it up, couldn't really come with a foolproof method.
The only method I've tested is this one:
First you need to create a dummy model (the same as the previous one)
BUT: give it the model "UI\Feedback\Target\Target.mdx"

Then you create that unit and increase the size according to the range (that's your job -.-).

 

[vibon]

I saw it once in a td map..
Do you know how?

Some Jass or?

 

[ap0calypse]

I just said you need to give a dummy the model "UI\Feedback\Target\Target.mdx"...

 

[vibon]

Now i made a trigger like this

third
Events
Unit - A unit Begins casting an ability
Conditions
(Ability being cast) Equal to Range
Actions
Set Loc[1] = (Position of (Casting unit))
Unit - Create 1 Dummy Range for (Owner of (Casting unit)) at Loc[1] facing 270.00 degrees
Animation - Change (Last created unit)'s size to ((Current acquisition range of (Casting unit))%, (Current acquisition range of (Casting unit))%, 100.00%) of its original size
Animation - Change (Last created unit)'s animation speed to 20.00% of its original speed
Unit - Add a 5.00 second Generic expiration timer to (Last created unit)

The problem. Is that.. It set the % of Acquisition Range.. Wich is much smaller than the Real Range..

I just thought of something but i'm not sure if it works and how precise it would be, how about changing its selections scale to be as big as his range?
If you can calculate the range of the tower, then you can make his selection to be something similar.
Example, tower's range 700 - selection scale 3.00?

=.= that's not true
The acquisition range is always greater than the real range (always, there are no exceptions).
The reason why it looks smaller is because the size is a percentage (if the tower's Acq. Range is 600, you set the size of the circle to 600%).

I've also said that you need to set the point value of the unit to its range, so the point value = range of the unit.
On top of that, you didn'tgive the dummy the locust ability.

You need to calculate the Size % versus the range yourself...

how about changing its selections scale to be as big as his range?

Yeah, I also thought about that, but didn't know how :/ (apart from creating a lot of dummy units in the object editor, each with a different scale :S).

That wouldn't be much of a problem, the real problem would be to make the selection scale to be the exactly same as the range of the tower...

 

[vibon]

then, how to calculate that? ..
I know the Math triggers..

 

[ap0calypse]

then, how to calculate that? ..
I know the Math triggers..

...that's up to you, you will need to come up with the formula yourself, as there is no preset function for it or any known formula (afaik).

All I can say is this: the unit art scale is multiplied with it's original size.
So if the scale is 1.50 and the size is 100, the new size will be 150.

You need to do some testing, increase/decrease the size of the dummy and compare it with the actual range, things like that.

Good luck ^^
