Losing control of a unit until deselected and then reselected.

[Itachi2020]

Hello,

During gameplay, players can occasionally lose control of a unit. They would have the unit selected, but it wouldn't respond to any actions like move or to cast an ability. To regain control of the unit, the player would need to select another unit and then reselect the original unit. The issue occurs rarely, but usually to at least 1 or 2 players per game.

Has anyone experienced an issue like this and found an occurrence?

It's hard for me to pinpoint a timeframe when the bug started re-occurring enough for me to realize it must be a trigger or something disrupting the gameplay. However, I think the below trigger is my best bet for where the cause is, due to the fact it manipulates a players selection. The trigger simply allows a player to scroll between their Leader unit and their Hero easily.

Does anyone see an issue with the below trigger that may cause these issues?

Thanks!

I would probably use temporary or global unit groups for what you are doing here, but:

I assume the problem lies in another trigger which handles unit behaviour?!

Ah yes I need to rid that leak in the condition. Thanks for the spot.

No, there's no triggers that manipulate player owned units directly in terms of behavior. Only dummies' on the occasional ability. However, the undead forces that are computer have a lot of handled unit behavior. Such as "attack move" to certain points and casting abilities.

Well you wrote that players sometimes lose control of their units, but your posted trigger doesn't interfere at all with unit control - so .

 

[Itachi2020]

No it doesn't, however the triggers involved select a unit. Which could interfere with control/behavior.

That's because in "(Unit-type of (Random unit from (Units currently selected by (Triggering player)))) Not equal to Leader" you used "Random unit" so it will be a probability, because that will only check a random unit of that group, you must check every unit of that group, for this you need use Jass Language.
