Unit comes out of range

[Krogoth]

I need to check coming out of range immediately, because it must remove some spell. If it is delayed, spell can be casted and mana/cooldown wasted (because effect must not take place out of range). (Spell must have no cast animation)
What I am doing currently, is
- eventually check unit comes within range
- eventually check unit leaves region
- every 0.1 sec check if unit is within range
Thus, you can use it in corner, which is not that critical, but still not good
Using less time period seems to be a solution, but some kind of retarded

The best way is add units to unit group when they are in certain radius of point.
Every 0.03 check for units in range and add them to a tempGroup.
Then check the main group and loop through it to check if units are in tempGroup.
If that unit is not in tempGroup then it is not in range anymore.

Also 0.03 is the normal time period. Almost all spells use 0.03 as a timer.

Ty, this looks much better than calculating distance
Does not solve problem on 100% though, so I have to check leave region also
Btw, just spent 20 min in searching of bug. That was GetFilterUnit() not working on filter for unit leave region event, but TriggerUnit() instead (!). So retarded. :/

You should not need a leave region event for this.
You should only need one trigger with one event in it. Unit in Range event.
With the extra events unit leave / enter region you could make it more efficient as you can turn the trigger off that checks for unit in range if no units are even close to it.

Also this post should be in WEHZ not in Triggers and Scripts.

I mean, if unit blinks out and uses spell before next timer tick. For example, using shift key.

With 0.03 timer it would be almost impossible for someone to get within range then blink out before that unit is caught.

Why 0.03 timer for spells specificly? Does it take too much unnecessary data to use shorter or?

I have a "mass mana burn" spell I use that summons a dummy to cast mana burn on everything around it. Should I use a 0.03 timer for that, instead of 0.01?

It is a good compromise between performance and smooth visuals.

Ideally you would want a 0.01667 delay as this would mean that not a single frame would render without the actions being performed however the gain for performance is often not worth it.

Unit in Range event.

This breaks auras as a warning. Auras seem to use the mechanics of this event in a mutually exclusive way.

I see. Thanks a lot
