Units prioritizing acu

didn't have time to check the replay :
but the pr about target priorities is this one : https://github.com/FAForever/fa/commit/0891e455f5845ed62104a32ef24cfe72b6ae65b8
petric did change some stuff here, but shouldn't have any impact for what been reported : https://github.com/FAForever/fa/commit/39f5b3291a77f02fdd7cf1dc45f8d32117bcb796

target priorities on the fly should work (with unability to change target on the fly to the ACU unless unit have the category 'SNIPEMOD').
As for pillar not retargeting automaticaly to T1 unit, it works as in the code : It always has been the same, it's priority is to shoot mobile unit. ACU doesn't have a lower priority than the other mobile unit, so it won't retarget. I guess it can be change, if wanted.
For percy its target priority are T1<ACU<T2<T3

So I could make a custom priority for advanced target priorities for MOBILE units and target the ACU once with a bunch of units and hey presto snipe mode reactivated for all selected units?

No, unless the unit has the SNIPEMODE category the ACU is subtracted from any target priority.

So am I misunderstanding keysers post or is he wrong about pillars not switching because the ACU and tanks are both in the MOBILE category?

This post is deleted!

I assume the ACU is not subtracted from any of the default priorities built into the unit blueprint, but the ACU is subtracted from any custom priorities. So if you made a custom target priority for MOBILE it would be translated to MOBILE - ACU unless the unit is allowed to prioritize the ACU.

I'm not sure that assumption is correct. Will test

it's what thomas said. You need to separate what i call "target priority on the fly" or could also be called snipemod / custom target priority; from normal target priority that don't have anything to do with the 'SNIPEMOD' category.

Haven't tested but if you have a bunch of units who are not in range of any other units and switch them to a custom MOBILE target category then manage to move them into range of a lone ACU before any other units come into range (which is quite doable because a lot of the time the ACU is positioned up front) then won't they just retain there lock on the ACU as the pillars did in this example? What you've done is essentially designate a sniper squad before attacking. They won't automatically switch to the ACU if already firing at other targets though.

if they are unit without the 'SNIPEMOD' cat, they will retarget, as soon as mobile unit come in range.
what would be interesting to see is if pillar that would keep the target on the acu in that kind of situation without using custom MOBILE, would actually retarget to other unit if you use the custom MOBILE target prio.
