[Trigger] Town Portal Trigger

[Solaris]

How to create a Town Portal
In my last rpg map, there were great distances between the battleground and a revive stone, it always annoyed me walking the whole distance. So I wondered if you could make a Town Portal System/ Trigger like in DiabloI+II, I read a lot of Threads on different sites, but never found someone who did exactly what I was planning to do.

So after some tries, here is my result:
1. First of all I made an Item called Townportal
2. I made two trigger, the first is for opening the potal in the level

• TP
  • Events
    • Unit - A unit owned by Player 1 (Red) Uses an item
  • Conditions
    • (Item-type of (Item being manipulated)) Equal to Stadtportal
    • ((Triggering unit) is A Hero) Equal to True
  • Actions
    • Unit - Create 1 Portal for Neutral Passive at (Position of (Triggering unit)) facing Default building facing (270.0) degrees
    • Set Location[1] = (Position of (Last created unit))
    • Set Port[1] = (Last created unit)
    • Wait 0.10 seconds
    • Unit - Move (Triggering unit) instantly to (Center of Gebiet 001 <gen>)
    • Camera - Pan camera for Player 1 (Red) to (Position of (Triggering unit)) over 0.00 seconds
    • Unit - Create 1 Portal for Neutral Passive at (Center of Gebiet 001 <gen>) facing Default building facing (270.0) degrees
    • Set Port[2] = (Last created unit)

3. The last thing to do is writing the Return-Trigger

• TP 1
  • Events
    • Unit - A unit enters Gebiet 002 <gen>
  • Conditions
    • (Unit-type of (Last created unit)) Equal to Portal
    • ((Triggering unit) is A Hero) Equal to True
  • Actions
    • Unit - Move (Triggering unit) instantly to Location[1]
    • Camera - Pan camera for Player 1 (Red) to (Position of (Triggering unit)) over 0.00 seconds
    • Unit - Remove Port[1] from the game
    • Unit - Remove Port[2] from the game

Its quite simple, but it works fine. Most important is setting the right variables.

Please correct me if I´m wrong or if you got a better way to realize it.

Your trigger leaks, you should put a Custom Script function at the end of the second trigger and put this code: call RemoveLocation(udg_Location[1])

Trigger leaks

Thanks, I´m going to add it. It could fix the problem that sometimes the port does not disappear and is unusable....

 

[sephiroth1234]

Not only that, without the Custom Script code that I gave you, when the ability is used very often, your map will lag for sure, a headaching lag!

• (Unit-type of (Last created unit)) Equal to Portal

´

Wait.. What?

Use

• (Unit-type of (Last created unit)) Equal to Port(1)
• Or -
  • (Unit-type of (Last created unit)) Equal to Port(2)

Hmm good point with the lag, I´ve noticed that before, using point variables seem to be lagging at all.
Thx Etzer I´m not that good in setting trigger, so sometimes I think far too complicated....

Solaris, please write here what your scroll really does, i mean every detail and i'll write the leakless triggers here

 

[Solaris]

Allright the Sroll does nothing at all... but it need to be usable (not consumerable). I think thats all, in my case I used the scroll of haste. just to move faster once you are in town.
Thx all for fixing the trigger!

Fixed TP-Trigger

Allright it took some time but here I post the fixed TownPortal-Trigger

1. Create an Item called Townportal, I used the Scroll of Haste so my Hero could move faster in town, but its up to you what to choose

2. Create a Portal Unit, I´ve chosen the portal from the human campaign. Make it invulnerable otherwise creeps will attack it.

3. The first trigger initiates the Tp-Creation, Unit uses the item which was created before. I´ve made two special townportal areas, one that leads you into town (Area001) and one that let you return (Area002).

• TP INI
• Events
• Unit - A unit owned by Player 1 (Red) Uses an item
• Conditions
• (Item-type of (Item being manipulated)) Equal to Stadtportal
• ((Triggering unit) is A Hero) Equal to True
• Actions
• Unit - Create 1 Portal for Neutral Passive at (Position of (Triggering unit)) facing Default building facing (270.0) degrees
• Set Location[1] = (Position of (Last created unit))
• Set Port[1] = (Last created unit)
• Wait 0.10 seconds
• Unit - Move (Triggering unit) instantly to (Center of Gebiet 001 <gen>)
• Camera - Pan camera for Player 1 (Red) to (Position of (Triggering unit)) over 0.00 seconds
• Unit - Create 1 Portal for Neutral Passive at (Center of Gebiet 001 <gen>) facing Default building facing (270.0) degrees
• Set Port[2] = (Last created unit)

4. Now write the return trigger

• TP BACK
• Events
• Unit - A unit enters Gebiet 002 <gen>
• Conditions
• (Unit-type of (Last created unit)) Equal to to Port(1)
• ((Triggering unit) is A Hero) Equal to True
• Actions
• Unit - Move (Triggering unit) instantly to Location[1]
• Camera - Pan camera for Player 1 (Red) to (Position of (Triggering unit)) over 0.00 seconds
• Unit - Remove Port[1] from the game
• Unit - Remove Port[2] from the game
• Custom script: call RemoveLocation(udg_Location[1])

 

[sephiroth1234]

Each trigger leaks a location, better check the first trigger and the action:

• Camera - Pan camera for Player 1 (Red) to (Position of (Triggering unit)) over 0.00 seconds

and at the second trigger:

• Camera - Pan camera for Player 1 (Red) to (Position of (Triggering unit)) over 0.00 seconds

It leaks the location (Position of (Triggering unit)).
