Some questions about pathing in latest develop - 148

[Godde]

Spring 85.0.1-148-g69df6ab develop
Most testing done in Spring1944.

Narrow paths are still hard to find for the pathfinder when pathing at long distances. I tried this on TheRockFinal near the middle south hill that got a long curved narrow path up on the hill.
Is there are a way to increase the resolution of the pathfinder? If so, can it be game specific and maybe even map specific? Would it be possible to write a script so that depending on map pathing costs a certain resolution is used?

Friendly and enemy units can still get stuck in eachother. What appropriate ways are there to avoid this? I've heard its possible to make friendly and enemy units push each other. How do you do that?

It seems that all landunits slow down when they turn unless they have turnInPlace=0;
Based on my testing I'd say that when the unit has turnInPlace=0 it will still slow down to the turnInPlaceSpeedLimit or the default calculated value.
You can also adjust the rate at which they slow down with brakeRate.
What other ways do you have to control their speed when turning?
It seems abit silly to me that infantry in S44 should have turnInPlace=0 in order to not slow down when changing direction and low brakeRate doesn't feel right. With what other ways can their speed be keept higher?

Of course, the code wasn't changed and ancient design flaws don't magically go away by themselves (see also).

If it tells you anything, QTPFS owes its existence to (and solves) this problem.

1) no (if you don't count giving intermediate move orders)
2) many maps have at least one region in which a theoretical shortest path crossing it cannot be found unless the resolution is maximal, and pathfinding at maximum resolution over large distances is slow, so this would trade one flaw for another

I've heard its possible to make friendly and enemy units push each other

Don't trust your ears, your eyes are better because they can read the changelog:

Code: Select all

make pushing of enemy units during collisions a ModInfo option ("allowPushingEnemyUnits")

What other ways do you have to control their speed when turning?

None that are reliable.

It seems abit silly to me that infantry in S44 should have turnInPlace=0 in order to not slow down when changing direction

And what would a good alternative that simultaneously preserves normal turnInPlace=1 behavior be?

How do you turn on QTPFS? I don't think I was ever told (It should state how to in the changelog really).

Old news apperently. I'm trying it out with Spring 1944.

I tested Spring 82.7 again and infantry doesn't slow down so much there. They only seem to slow down alot when they turn above 90 degrees. So that would be the preferable behavior in my opinion. That units with turnInPlace = 1 slow down alot when they are making a turn higher than 90 degrees.
