tl;dr:
Alerts for a damaged entity are useless when it's a wall, so in this case it should be disabled or demoted to a yellow notification.What:
Currently, whenever any kind of entity is damaged or destroyed, a red alert triggers. A red alert shouldn't trigger when a wall is damaged, at the most it should be a yellow notification. There are some possible variations, which would be easier to explain in the context of the "Why".Why:
Alerts are supposed to trigger when something bad and unusual happens that requires your attention. Walls being damaged are not that, their entire goal is to be damaged; the alerts are distracting and their frequency is numbing, discouraging checking alerts at all, even those which could be more important.Having it as a yellow notification makes more sense.
Turrets being damages is also usually not very interesting, so this change could apply in general to military entities.
Alert preferences could change over the course of the game - at some point I might not want to be notified when a wall is destroyed, for example - so the best option would be to have settings for customizing the kind of notifications you get for different events (damage, destruction) concerning different types of entities (wall, turret, civilian, etc.)
Further thoughts:
I've taken a break from Factorio in the last ~2 years while waiting for the expansion. I haven't gotten very far yet in Space Age, but you can imagine my disappointment when I saw that something I (and others) have complained about over a decade ago apparently still hasn't changed.I tried to search for any relevant recent developments, but couldn't find any. Solutions discussed in the past include using commands - which can disable certain types of alerts entirely, but without distinguishing entity type; and modding the entity properties, but AFAICT this doesn't distnguish damage from destruction, and can only disable, not change alert type. And I'd rather not use a mod for this to not mess up with achievements.
If there is any solution within the currently available methods, I'll be happy to hear. I will also appreciate any thoughts about why something like that hasn't been done - too difficult to implement? Everyone except me likes alerts for damaged walls?
