Basically a version of Pudge Hook.
With a small exception that this one works with blinking.

//===========================================================================
//  Demo spell for use of ABC timer attaching and PUI unit attaching
//  Author: Cohadar.
//  Date: 02.December.2007
//
//  How to implement:
//  Copy triggers ABC, PUI, CSSafety, and this trigger in your map
//  Copy all units and abilities into your map, then change raw codes in triggers
//  Make sure your trigger names are the same as scope names
//  or spells will not work. (I use local triggers)

Magic leash will extend from caster in the throw direction searching for something to grab.
Once it finds something it will engulf it with magic threads and pull it towards the caster.
Enemies caught inside net will be damaged.

Huh what does this do? Do you expect everyone to play dota and know who pudge is?

A short description should be included. Generally speaking, the tooltip.

Nice as usual , imo put all your spells in a spellpack instead of releasing 3 day after day.
Rep if I could XD

for those who dont know what "puge's hook" is, basicaly puge is an abomination, you know, the fat undead peice of sewed up corpses.... so he has this hook that he can trow (acutaly on the model it looks like its a part of him, anyways..) he trows it forward and when it touches something itll drag it back to himself, the hook will retract after a certain distance

anyways the simple version as usual
Code:
Abomination trows a projectile -> If projectile hits -> drags a unit back with the hook
                                             |
                                             v
                                      Hook comes back

It's really strange when two nets grab a unit... It looks like it is slowly duplicating and ... it's scary ^.^

It does not make errors, so it is fine by me.
I am not going to add 200 more lines of code just to correct a rare glitch.

It could be done by allowing chain pooling (multiple units pulling each other) like in pudge wars, but why would I want to recreate pudge wars for a purpose of a single spell.

And even if I did that there is no guarantee that some other spell that moves units will not interfere with this.

So basically it is a problem for the one who uses this in their map,
and it is commonly solved by using a joint movement (physics) engine for all spells that move objects, but that is like I said a personal problem of your map.

Couldn't adding a hooked unit to a global group , while its hook then make a condition to check if it was already hooked? That would remove one unit being hooked twice problem in a few lines would it not?

Or check for the buff.

That is if you used Shackle for it?

o_O Well I tried bugging the spell by adding a quite simple new trigger that runs at 5 seconds elapsed. Simply moves the heroes on both side of the death knight and orders to shackle him so to see what happens if he is shackled at the exact same time.

Funny thing is when I tried to test every single trigger disabled itself and gave me all these errors. ( I was using newgen )

NewGen did not load properly if it disabled all triggers.
Make sure there are Extensions, Grimoire and Jasshelper menus visible before attempting to compile anything with newgen.

If newgen does not load those menus at once, try again.
(turning all other applications when newgen is loading prevents this error)

This spell could use a PUI update, and also needs a CS update and ABC to work with 1.23+ patches...
