Water Check

[Duhcake]

Meh, Didn't figure any better title, But to the point, Is there any way to check of you're unit is standing on water with trigger's? Simple question would be likely answered with simple answer? x]

 

[Restor]

I know one option


Condition:Terrain Type Comparision- Terrain type of possition of triggering unit equal to XY terrain


But you must have all the water with the same tileset and nowhere else can be the same tile

I think you can check terrain pathable

 

[Shyhalu]

function IsPointWater takes real x, real y returns boolean
    return IsTerrainPathable(x,y,PATHING_TYPE_WALKABILITY) and not(IsTerrainPathable(x,y,PATHING_TYPE_AMPHIBIOUSPATHING))
endfunction

function IsPointWaterLoc takes location loc returns boolean
    return IsPointWater(GetLocationX(loc),GetLocationY(loc))
endfunction

I don't think i can do it with Jass... Well thanks for help anyways :]

Oh my god...

Okay, don't give up...
Create a new variable (CTRL + B) named Bool and make it a boolean type.
Create a new variable (CTRL + B) named temppoint and make it a Point type.

copy our friend jass trigger and paste in the map header (inside triggers, is the first trigger named equally your map name, it have a map as icon, inside have nothing)

now inside the trigger you want for the spell do:

• AFF
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to YOUR ABILITY!
  • Actions
    • Set temppoint = (Target point of ability being cast)
    • Custom Script: set udg_Bool = IsPointWaterLoc(udg_temppoint)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • Bool Equal to True
      • Then - Actions
        • -------- DO YOUR ACTIONS HERE! --------
      • Else - Actions
    • Custom Script: call RemoveLocation(udg_temppoint)

I shouldn't be doing this, since you gave up.
But never give up again.

You could also do regions for all your water areas:

• Events
  • Unit - a unit enters Water1
  • Unit - a unit enters Water2
  • ------ Ect. for however many water regions you have ------
• Conditions
• Actions
  • Game - Display to (all players) the message: OH MY GOD! DON'T GIVE UP! HE'S ON WATER!

It may get a little tricky if you have many corners. But patience and determination, and you'll get it. As well, it helps if you go read a JASS tutorial, as GUI is a little limited when it comes to triggering.

WTF cant we check terrain level in GUI ?
we must be able to like terrain hight level is lower than 0

but you can have water in mountains...

 

[-Berz-]

• (Terrain pathing at <your point> of type Floatability is off) Equal to False

This condition will check if the point is located on water.

 

[Saishy]

• (Terrain pathing at <your point> of type Floatability is off) Equal to False

This condition will check if the point is located on water.

why double negative?

 

[Archangel_Tidusx]

Its not really double negative. It's like saying
your unit cannot float is equal to false.

that rules out whether or not the unit is on water.

 

[-Berz-]

why double negative?

It works for my spell, why shouldn't it work for his trigger, its the same thing.

Only for deep water:
Make two dummy units, one that is amphibious, one that's not, both with 0 collision... create them both on the same spot, do a SetUnitPosition(unit, spot_x, spot_y) for both of them (to force an update), and check if they are both still on the same spot... if not, then it MUST be over deep water (if the terrain was cliffs or something, the update would still move them to the same spot, just not the original place).

Good idea, but sometimes people (like me) decrease the level under deep water.

Well, Do these work if the water level isn't created with cliff's, Cause i made the water level by creating the map with swallow water, And heighened the terrain at some spot's so it would look nicer... Gotta try out some of those, Thanks again for helping me out :]

I think the best way would be the floatability check.
All the other ways seem to be specific to certain situations.
