Lasso v1.00

Toss a magical rope around the target, grabbing it and holding it close.
.

Why Dismember sucks:
It has screwy casting distances, and neither the caster nor target can move during the spell.​

Why Lasso doesn't suck:
Both the caster and target can move while a unit is lassoed. The user can input a break distance at which point the lasso will snap, a minimum distance required for the lasso to illicit a pull effect, as well as an equation which allows completely unique pulling physics. In other words, this is what Dismember should have been.​

Don't mind the other triggers in the map. All you need to look at is what is contained within the Spells folder, specifically the trigger Lasso.​

Enjoy and please comment!

Very nice. I don't know JASS, but looking at it in game, it's a great spell. Good job, +rep.

Regarding the comparison with Dismember, why would you be able to move while being bitten and chowed down on? o_O

But nice job. It works very smoothly and everything.

omg i love you and hate you...

i love you because its awesome and well-coded.
but i hate you because i had the same idea just yesterday :/

+rep anyway

@aceheart:

the functions take a level argument, so your data can be more dynamic

So people who use this and actually look at the code can base the values on spell level :thup:

I think AceHart was asking "Why not constants?" in light of the fact that at the moment the functions don't actually use the level :p

if that be the case, then why on earth are they connected by a rope?

Aha, that's awesomee!!

Increadible! It is actually something I'm going to use on my map.
^^

You rules emjlr3!
It is cool to mix this spell with another one, like Banish for example. I changed the damage type to spell and the result is a ghost trying to run from your rope ^^ And then you can freely cast your channeling spells.

I made a very simple first-try JASS spell using lightnings to link to your target and in a few days others make similar spells :S

between good job, I couldn't make something like this

Uh, really? I don't recall. Dismember is Aerial-Shackles-based, but it doesn't use the Aerial Shackles animation IIRC.

> Why not global constants?
It's better if the spell writer leaves some constants to functions, so they can differ from level to level.

no one seems to hate this or have any problems, so I'll move it

Dismember does not connect the two units with a rope, it just uses a blood animation, instead of the shackle animation :p

um....this uses a struct stack, no attachment system needed
