How to create a non-selectable summon that follows you?

[Mukyuu007]

I know this is possible because in the Warcraft custom map Defense of the Shrines (A DotA rip-off using Touhou characters), a hero, Youmu Konpaku, has her ghost-self follow her around whenever she casts that summon ability. It cannot be selected but it follows her around as well as attack whenever a unit is close.

Is it using a 'Follow Unit' trigger or is there something more?

Add an ability called "Locust" to that unit.
The ability in hexadecimal form is 'Aloc', here's how you add the ability to the summoned unit (assuming you "create" the unit via trigger);

• Summon
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Summon
  • Actions
    • Set TempLoc = (Position of (Triggering unit))
    • Unit - Create 1 Summon for (Triggering player) at TempLoc facing Default building facing degrees
    • Set SummonUnit = (Last created unit)
    • Custom script: call UnitAddAbility(udg_SummonUnit, 'Aloc')
    • Custom script: call RemoveLocation(udg_TempLoc)

This will make your unit to be unselectable.

You can also add this ability via Object Editor.

For the trigger to follow the unit, perhaps it uses interval or one-time follow order, it must have some algorithm of an AI, you need to create it (trigger it) to behave like human-owned unit.

I'll give it a try

The ability in hexadecimal form is 'Aloc'

Hexadecimals can contain numbers from 0-9 and letters from A-F.

I had a trigger doing this in one of my maps.

I have a wolf unit that has a spell creating 7 transparent illusions of itself (same unit but with locust ability and changed transparency).
Upon creation, all I did was order it to right click the main wolf unit (I have a feeling follow will work the same).
Now they will follow you everywhere, and target whatever the main wolf attacks via right clicks, else it attacks random (only if main wolf is attacking also).

Are you correcting me or adding additional information ?

Correcting you .
'Aloc' isn't hexadecimal, it's ASCII. Hexa is limited to 0-9 and A-F (16 characters), while ASCII has 256 different characters.
(In hexa, "a" and "A" are both 10, but in ASCII "a" is 97 and "A" is 65).

 

[defskull]

So 'Aloc' is in ASCII ?
Same as 'A000' ?

 

[ap0calypse]

Yep All those raw Id's are ASCII (plain text).
This post contains some information on how to convert those codes (like 'Aloc') to an integer. Works the same way as all other bases though (deci, hexa, octa, binary, whatever).

 

[Almia]

Yeah,Aloc is an ASCII
Hexadicimal is like this:
0xD0100
This is the hex of the Inferno order

 

[Dr Super Good]

Each character in 'A000' needs 2 hex characters to represent.
