Super fast explanation, I have a stack of boxes in a map with a Z difference of 64uu between each box.
I have set up a path by using LiftExits and LiftCenters to show bots where to jump.
This all works well except for "Classic Mode" with the non-boosted JumpHeight, "Hard Core" and "Turbo Mode" with the boosted JumpHeight work a treat.
Any ideas for a custom LiftCenter that becomes a null path on "Classic Mode"?
Custom LiftCenter NavigationPoint.

Re: Custom LiftCenter NavigationPoint.
Check "PlayerJumpZScalling" delivered by GameInfo child classes. Investigate first what values are given Classic vs HardCore.
Any value which is under "HardCore" mode jumping needs, will need whatever tweaking:
#1 Assign a value in PostBeginPlay (eg: bNoJumpOption if jumping is low from GameInfo ) - if this value goes True, then Cost for "Seeker" should return 100,000,000. If value is false proceed executing parent code - aiming function SpecialCost.
OR
#2 If this Jump-Scaling is lower than "HardCore" allows, call a "for" cycle for removing Paths/upStreamPaths from this node and those connected with this node - Code I think is already provided by TranslocDest class for games that don't use Translocator. In similar format you can remove paths if Jump Scaling doesn't match what route is requiring.
OR
#3 If Jump-Scaling is low, just increase cost of node and get rid of "bSpecialCost".
Extra-Note: Bots embedded in maps in first session won't jump anyway until they get killed at least one time. This is happening because they are not initialized normally which means to take in account this "PlayerJumpZScaling".
Edit: Here is some data - DeathMatchPlus:
And then LiftCenter can be locked/screwed if "Level.Game.PlayerJumpZScaling < 1.1". Increasing cost or removing paths I think are doable even with an external actor tracker not only with a custom LiftCenter...
Your idea is indeed an interesting one .

Re: Custom LiftCenter NavigationPoint.
Thank you, I'll have a play around and see what I can get working.
Worked a treat thank you sector2111!
here is the code:
Note: I have only done the most minimal testing but it appears to be working perfectly.
Note that this is a LiftExit not a LiftCenter!
In my level I have two 64uu jumps in a row, one small box 64uu tall and another 128uu tall, this actor is placed as the start of the path on the ground level, normal LiftCenter (with MaxZdiff=128) on the first box, normal LiftExit on the second box.
Obscure usage case but could be useful for mappers!
I should probably make a custom LiftCenter for the super obscure case that a bot will get stuck trying to get up to the second box (starting from the LiftCenter) but lazy and not entirely sure if that is even possible.
Edit: Mods: the title of this thread can be changed to solved, I can't figure out how to do it ha.

Re: Custom LiftCenter NavigationPoint.
Epic was using something like LiftCenter probably because of speed and accuracy. Usually their "LiftCenter"s are connected only in two directions with 4 reachSpecs. A LiftExit might host links in more directions blocking paths for a larger spot supposed have some passing through. When a LiftCenter (internal point of a Combo) is locked, it's not needed anything else outside - all routing is closed there. But... of course any node can be locked more or less internally and it will work guaranteed if code runs logically. Patch plugins which I wrote are able to turn a PathNode into a sort of PathToggler locking/unlocking routes connected with some desired map event (even game situation).

Re: Custom LiftCenter NavigationPoint.
Allow me a bit of bump concerning generic jumps that are not possible in "Classic" settings. The other solution for customized maps where navigation should be left alone and without processing constantly "SpecialCost" means to simply get rid of paths from outside of navigation network.
This means we can use a... KeyPoint where user will write connection that needs to be inactive in "Low Jump" gaming.
I wrote this stuff for recent edit... several functions are copied from elsewhere since I had them done and already tested.
When stage goes evil, we have the report:
Of course it can be completed with more info, such as describing if that Path which needs to be removed doesn't exist because some boys are just pushing buttons and InventorySpot mentioned is gone for good at once with jumpy path. During run-time it won't be any processing of any SpecialCost except those valid needs from stock or whatever.
Sample Stage...hacks tweaking for getting compiled is to remove offender destination for jumpy Reachspec from Navigation chain. Engine won't be able to calculate the route here and no crash will occur because data is still in map but... not chained.
