[Trigger] Following pets

[Hargoth]

In my RPG i need a trigger which keeps a pet (or just unit) close to a hero, in other words so it does not walk to far away or get left behind. Now i know your thinking the owner of the unit could simply keep them together but if an owner so chooses he could mess up other triggers in the game. Thank you for reading!

Maybe just do something like.

Every 0.3 seconds of the game
If (pet) is not in within range(350) of (petOwner)
then move (pet) to a random point within range(300) of (petOwner)
else
do nothing

Maybe instead of a move instantly, do an issue move? That way it doesn't jump around the place and it doesn't look so bad. If that case, I'd make the pet's movement speed the same(maybe a little faster) than the petOwner.

That helps alot mate, thx

Is it a non-combat pet or combat pet? If it is then constantly ordering it to move to your Hero wont really work....
Also. is it a summonable pet? Is it created through a trigger? Feel free to PM me.

You could create an order for the pet to guard the hero and make it unselectable:

• Trigger
• Events
  • Player - Player 1 (Red) - Selects a unit
  • Player - Player 2 (Red) - Selects a unit
  • Player - Player 3 (Red) - Selects a unit
  • Player - Player 4 (Red) - Selects a unit
  • Player - Player 5 (Red) - Selects a unit
  • ... etc
• Conditions
  • Unit-Type of (Triggering Unit) Equal to <PET>
• Actions
  • Player - Clear Selection for (Triggering Player)

And maybe add commands too, such as attack, stay close etc.

In my map (Creature Island) I have a similar system. There is a minor problem though and that is that if one unit is faster than the other they will get further apart and also if they select the following unit and order it to stop it will stop following (until either issues a new order). With some simple triggers I guess you could fix these problems (teleport back if they get too far away)

• Auto Follow Creature
  • Events
    • Unit - A unit Is issued an order targeting a point
  • Conditions
    • (Ordered unit) Equal to Active[(Player number of (Owner of (Ordered unit)))]
  • Actions
    • Unit - Order CreatureTamer[(Player number of (Owner of (Ordered unit)))] to Follow (Ordered unit)

• Auto Follow Tamer
  • Events
    • Unit - A unit Is issued an order targeting a point
  • Conditions
    • (Ordered unit) Equal to CreatureTamer[(Player number of (Owner of (Ordered unit)))]
  • Actions
    • Unit - Order Active[(Player number of (Owner of (Ordered unit)))] to Follow (Ordered unit)

There is really simple and effective way to do this - that is if you dont want the player to have much control over the pet and rather want the pet to just fallow a single unit.

Edit Locus Swarm so its only 1 unit - your pet. Hide it in a spell book, set the duration to 999999 and use a trigger to make the unit cast it.

I guess that would work too. But difference between my one and your one is that in my map players have max control over the pet as well as the main character.

If you want your pet to basically always be within X range of your hero, just do what The_Nyne said. To prevent players from spamming stop on the pet, just make a trigger that detects when it receives any order. Check to see if the pet is farther than X from its hero, and if it is, just reissue the move order. (Of course you can see that this way the pet will literally do nothing except try to get back to its hero if it's too far away...which may be a problem.)

Uhh is this thread to help you or Hargoth? It looks like he doesnt want the player to have much control over the pet.. but i have been wrong b4.

Here's a simple Pet AI map I just made for you
(Haven't added leak removes because I don't find it necessary if its only for show)
This is how you should design your pet's commands
Note that this also comes with a command where you can turn on/off the AI, so you let the player decide whether or not the pet should be automated or controlled
Adding to these triggers, you can use a trigger that teleports the pet back to the caster if the pet is too far away (and if AI is on)
I feel dirty allover, I don't like triggering in GUI

Let's see, what can be improved?
1) If you have more than one pet, you can create an array of points (each one representing a point around the master) and then position each pet for each point.
2) You can add a better follow system, where if the degree to the targeted offset point is bigger than the masters degree to the targeted point then assign a new point that doesn't interfere with the masters point (not creating an X pattern where they cross paths with eachother), or something...

And here are the triggers for those who are lazy:
