Event: Unit comes into range...but no choice for in range of what!!

[Ruination]

I can't understand the usefulness of this event. It only allows you to choose pre-placed units for the range. Why is that?? Or I don't have a variable of the type required; in that case, what type do I need? I have a point and unit variable, what else could it be?

I need to play a one time effect on units when they enter into close range of a point or unit. The unit is on the point so either would work. It is a blackhole, and I just want units that are sucked into very close range to have a blink effect once, and then be hidden. Any guidance wise ones?

Just thought of something. In a perodic event, I could play the effect and then add them to a group. Thereafter, I will check if units in range are in the group, and if not, play the effect. That SHOULD make it so it plays once on each unit in range. Let's see...

No that will still play the effect every .04 sec for the first time I add it.

Thanks.

I'm not quite sure why, but all events only let you use pre-placed things. If you need the units not to be pre-placed then use the Trigger - Add Event action after you create them.

Unit- Create 1 Black Hole at . . .
Trigger - Add Event (Unit within range of (Last Created Unit))

Wow I've never seen this 'add event' before. I will try that first thing after work thanks Lumpy.

the events that you specify in your triggers are registered when your map is loaded. Events do not persistently update themselves in any shape or form, they only register once and that's it. Therefore telling an event to operate on a variable won't work because, when the event is registered, variables haven't been initialized yet - they exist but they just haven't been assigned values.

Therefore, if you were to have an event "unit comes in range of <variable>", when this event registers at map loading time, <variable> has no value and therefore the event would look like: "unit comes in range of <null>" - which of course won't do anything!

The aformentioned "Trigger - Add Event" is useful, because, at a certain point in time in your map when your variable DOES have a value, you can THEN register the trigger and use the variable. The trigger will register once only at that exact point in time, and if it uses your variable, it will take the value of the variable at that exact point in time. If the variable changes value from then on, the event will keep using the old value.

y dont you use the event that is 2 values under that one?

u know the one that says:event:a unit comes within range of(triggering unit)

thats easier

MooMooMan, that's the problem with his trigger. The Unit - A unit comes within range action only lets you use preplaced units, and his is placed in the trigger editor. The editor won't let you select anything under the Event response column. The Add Event thingy should work fine.

Okay do I need to set my variable to null afterward so that it will reset since you said it'll keep using the old value? Or, how do I manage to make this work multiple times since the blackhole will be placed at any location numerous times.

Ok I'm sorry but I have no idea how to use this. What trigger should I add this event to? How do I call this event which I created?

Thanks guys.

just add the trigger to the one that does the actions you want to happen when the unit enters range, and don't worry about reseting variables, it is entierably multi-instanceable.

Holy crap it works. Sweet thanks all
