Question: What caused the M314 Motion Tracker to lag so much?

[Rob606]

Genuinely curious, as I know it was taken out due to the amount of lag it created. What was it that caused it's incredible amount of lag?

I assumed it would use a similar code that operates the Sentry Gun - item identifies object that doesn't have IFF and initiates a script to fire at said object.
Naturally that's a huge simplification, but I am still interested in why it's so laggy.

From what I remember hearing, the motion tracker used some slapped together code that might have utilized the proxi sensor which the code is removed or disabled because it caused lag because of the amount of times it needed to update? I don't actually know I'm just trying to recall from what I've heard.

Scanning for every tile in 10x10 range (100 turfs), applying and deleting every dot on the minimap, and more tiny stuff being executed every single second. Now combine that with 4, so 400 turfs are scanned each second if they had a mob on them.
