Question about Unit - A unit leaves <Region>

[WispY]

Just 1 question, put the yes/no answer (and if "yes", put a trigger action or Script text to solve my problem, please):
When trigger event is like

"Unit - Generic Unit Event"​

we can get unit using

"Set UnitValue = (Triggering unit)".​

My question is, can we get region, like

"Set RegValue = ..."​

when we use event like

"Unit - A unit leaves <Region>"?​

It is needed when I "don't know" what region stands in event, or I use 10-20 events with regions.

When a unit enters region, save it somehow (an array or hashtables), bind it to the unit. When the unit leaves some region, you load the region it was in last, and that will be the region it left. This works unless you have overlapping regions.

Maker, do you mean I must create N (3 regions - 3 triggers, 100 regions - 100 triggers) triggers for every region unit can enter:
"Unit - A unit enters <RegionN>"
"Set Regions[number+1] = <RegionN>"?
The answer to my question must remove N triggers from my map.

My map is working G R E A T now, but I use 16 triggers for triggering 15 regions, it looks like every trigger have
"Unit - A unit leaves <Region>"
"Set _regmotion_reg = <Region>"
"Set _regmotion_unit = (Triggering Unit)"
"Trigger - Run 16tr (checking conditions)"
And, last (16) trigger has action upon this unit + region it leaves.

It is... big list of trigs, so I want to see
"Unit - A unit leaves <Region1>"
"Unit - A unit leaves <Region2>"
"Unit - A unit leaves <Region3>"
...
"Unit - A unit leaves <RegionN>"
"Set _regmotion_reg = ..."
"Set _regmotion_unit = (Triggering Unit)"
...actions...
In O N E trigger, so I won't create 16 triggers.
But "Set _regmotion_reg = ..." is lost, I can't find anything like (TriggeringRegion)...

When you leave a region, this system will create a footman in the region you left.

There are two versions of the system. One uses a wait, but is not necessarily 100 % accurate but you can test it. The other is 100 % accurate, but requires you to place 2x the amount of regions.

You only need three triggers for the system. Well two actually if you merge the initialization with Map Initialization trigger.

There is a really simple way to do this but I'm thinking you don't know vJass?

Cant you do it with a generic unit event?

• Unit - unit leaves region

then your conditions like triggering unit = ... and
triggering region = ...

You could do it in If_Then_Else to

hope that helps...

 

[Maker]

then your conditions like triggering unit = ... and
triggering region = ...

His question was about how to get the triggering region. He knows about <triggering unit>. There's no <triggering region> in gui

 

[Berb]

There is no triggering region, but regions are global variables (or at least the regions in GUI, which are actually rects).

Thank you, Maker! But I need to learn Hashtables before I use your system, and I have some questions with that, those I can answer with Hastables knowledge only. Such as "What if 2 regions have same points?" "What if a unit uses Blink spell or just jump over that a little bigger region?". Anyway, nevermind these, I will use my [N+1]trigger system for N regions now, because I have already written all triggers for them (they work P E R F E C T L Y, even if I 10x speed up my game). When I learn hastables, I will try to upgrade your system upon my needs, thanks again for that map!
Last question: how to close the tread?
