Leave within range?

[APproject]

Hey.

It is somehow possible to detect unit leaving within range? There is an event *Comes within range*, how about detecting unit which is far enough?

Thanks.

there are some Jass functions called:

constant native IsUnitInRange       takes unit whichUnit, unit otherUnit, real distance returns boolean
constant native IsUnitInRangeXY     takes unit whichUnit, real x, real y, real distance returns boolean
constant native IsUnitInRangeLoc    takes unit whichUnit, location whichLocation, real distance returns boolean

Which checks if a unit is in range of something else (unit, position or location depending on which one you use).
It returns a boolean as you can see.

You could do something like:

if not(IsUnitInRange(myUnit, otherUnit, 200)) then
//do something
endif

This will check if the unit is not in 200 range of the other unit.
Couldn't that work with a periodic event?

In custom script it looks like this:

• Custom script: if not(IsUnitInRange(udg_myUnit, udg_otherUnit, 500)) then
• Some actions here...
• Custom script: endif

Ah, it is in Jass. Thanks, Hashjie.

You're welcome

I suppose it is pretty simple to put this in a periodic event trigger that gets activated at a certain point? It's not an event so that's something you'll have to figure out. Or you could simply use it at a certain point to check whether something is still in range.

How should I replace myUnit and otherUnit? With variables?

How should I replace myUnit and otherUnit? With variables?

If you use udg_ in jass this means that it represents a variable in GUI.
so in other words: udg_myUnit is a GUI variable called myUnit.
The Jass native shows which types of variables can be used (takes) and which types of variables are returned (returns).
This is the same for any function in Jass.

You could even do something like:

• Custom script: set udg_myBoolean = IsUnitInRange(udg_myUnit, udg_myOtherUnit, 500)

this way myBoolean will be set to true if myUnit is in 500 range of myOtherUnit, or will be set to false if it's not.

You can also use jass functions like: GetTriggerUnit() to refer to the triggering unit.

Here is a little list:

GUI Form	Jass Form
Attacked unit	GetAttackedUnitBJ()
Cancelled structure	GetCancelledStructure()
Constructing structure	GetConstructingStructure()
Decaying unit	GetdecayingUnit()
Dying unit	GetdyingUnit()
Entering unit	GetEnteringUnit()
Hero manipulating item	GetManipulatingUnit()
Learning Hero	GetLearningUnit()
Leaving unit	GetLeavingUnit()
Leveling Hero	GetLevelingUnit()
Loading unit	GetLoadedUnitBJ()
Ordered unit	GetOrderedUnit()
Ownership-changed unit	GetChangingUnit()
Researching unit	GetresearchingUnit()
Revivable Hero	GetrevivableUnit()
Reviving Hero	GetrevivingUnit()
Selling unit	GetSellingUnit()
Summoned unit	GetSummonedUnit()

Remember that triggering unit is faster

Alright, thanks for the info, it works.
