Water Check {how to check if the unit is in the water?}

[bReathl3sS]

Hi guys.

Is there a way to check whether a unit is in water?
And is it possible to differ between "deep" water and "dead water"/"shallow" water

Basically I want to detect whether a unit moves into/out of the water, so I can do some actions.
An alternative solution would be making regions and detect a 'Unit - Enters/Leaves Region', but with a naturally looking ocean this would be really time-consuming to create so many regions.

Thanks for any ideas or scripts. I searched, but was not successful.

Greetings,

If you are using Blizzard cliffs, then it's possible by checking the cliff level of the unit (search under Integer comparisons). I don't remember/know of any other (safe) way.

By the way, questions regarding how to do this or that go on the World Editor Help Zone.

Probably not the best way to go about it, but you could make regions for shallow water and make a "Unit enters region"-trigger.

unit enters location would suck because i would have to make more than 500 regions for this.
i try the method from rui.
and why should this trigger go und world editor help zone?

i searched for a jass script or suggestions for triggers that could make this
well not my decision.
thanks i'll try it

EDIT: ok it works, this way it is possible to detect whether the unit is in the "deep water" (cliff height 0).
thank you.

greetings

Else you can use a tile under the water. Lets say you use a stone tile under the water, then you use the triggers to detect which tile there is below the unit.

But you that also means you cant use the tile any other place in the map.

An easier way is to make an Invisible Dummy Unit.

 

[bReathl3sS]

what type of dummy do you mean?

An easier way is to make an Invisible Dummy Unit.

And then detect when any unit comes near the unit? = alot of unit.

Not a good idea...

 

[bReathl3sS]

yeah thats what i thought too, but these are many many units....

If you got one free tile in you map, place it under the water. And check like every 0.3 if the unit is above the tile. Then you have detected the water..

No.

You can check the terrain pathing to see if it is floatable - this actually means the water has to be a little deeper than the minimum (Though with cliffs it doesn't matter).

Alternatively, you can use the above method to create a region which encompases all water on the map. The upside of this is that it's blazing fast to detect units entering/leaving water. The downside is that it takes a while to initialize (freezes the game for ~5 seconds on a 320x320 map).

Mekc's way of doing it works,
i used it in my map and it works perfectly

It's laggy and inaccurate. Saying there are more feasible methods would be a gross understatement.
