[Trigger] Wondering alone

[Craphter]

I created a special unit, wich is invulnerable, but as i dont want it to be used as a spy, i want it to be at a minimum distance from a player owned unit...
I mean, the unit is called Healer, and i dont want the healer to be used as a spy, so i want it to be allways close to a unit of the same player...
How can i make that? I seriously have no idea where to start...

I'm not quite sure what you mean..

However if you don't need to have the unit to attack, then set it's Combat - Attacks enabled to none in object manager. Then use unit - issue order targeting a unit - follow.

That's a simple solution, however not knowing your system it's difficult to say if it satisfies your needs.

I think he means he wants the unit to be invulnerable, but cant be used to follow the enemy heros/troops/ watch their base. I can only think of a way to do this as long as it is within the acual main town, using rects and other things. But thats only if thats what he wants

 

[Craphter]

Yeah, Coolty thats what i want... Its invulnerable, so it can go anywhere, but i dont want it to be used as a spy... so if its not close to a unit owned by the same player, it goes back to base or something...
I thought of this:

• Wondering
• Events
• Unit - A Unit Leaves (Region 1)
• Conditions
• Actions
• Unit - Move (triggering unit) instantly to (region 2)

But i realased that, if i did it like this, the healer would be usless in combat, when the player invades the enemy's base... since they have to leave region 1...

Ah, I see. Well you can use triggers to calculate the distance between the healer and the closest unit owned by the same player. Then if the distance is too great, then teleport the unit instantly to the closest unit.

 

[Craphter]

THAT is exactly what i wanted... just dont know how to...
A little hint?

EDIT: Updated map in the post below.

Maker says it right... you might want to get the GetClosestUnit jass systme in the Jass section...

Then GetClosestUnit to the invulnerable unit,
then you check for whether the distance is greater or not then the distance you define;
if greater --> teleport.

You might want to be checking for the distance at 1 second intervals... I mean it doesn't have to be precise in this case you know...

 

[Maker]

It's all there in the test map I posted ^_^

Though it would be better to first check if there are unit inside given radius, if not, only then search for the closest unit.

EDIT:Updated.

Remember, you need to check for an OTHER unit-type, because otherwise you could just send 2 healers side-to-side to their base.

 

[Maker]

Was that comment aimed at me? Because my trigger takes that into account.

 

[Yixx]

no i was too lazy to look at the trigger, but it was just for IF ;]

 

[swipe5weep]

create a trigger that will compute the distance between points

 

[Craphter]

Ok, thanks a lot Maker, + rep.
Swipe2weep, thats what Maker did
