NLCB - New Limitless Collision Box

Perhaps I found a better alternative way to reduce buildings collision boxes...

1) Collision box is reduced from all 4 sides of the buildings

2) Building maintain snapping with roads and other buildings



3) When a building snaps to next building, moving it further, it overlaps

4) when a building is placed, it is possible to lay a road partially overlapping it



5) Under no-collision part of the building, on slopes, fundations don't disappear
Before...

Now...



...other photos of my experiment







I'm still testing to understand why, in some cases, if i make no collision to big, some buildings freeze game
.

 

Now I'm just testing under what conditions and parameters such modification is usefull and stable.
I'm not a modder, but I think to create a mod for this purpouse will be easy.
It could be usefull for whom likes to overlap buildings on slopes...on plain terrains, classical limitless collision solutions are a better choice

What i discovered:

1) modifications affects all object in the game (buildings, roads, ploppables, and every modded building u add on game...)
2) buildings can't stand a no-collision radius >= 20 meters (selecting any building from menu, game freeze),
road can't stand a no-collision radius >= 8 meters (selecting any road from menu, game freeze, but not selecting some ped paths or freeways),
3) It seemed that game freeze if an object get a collision reduction equal or bigger than his total collision box
4) BUT if, for example, i load game with a no-collision radius=15 and i plop buildings merging them at maximum possible,
and later i go out from game to change no-collision radius to a smaller value (for example radius=2),
i expected, when i restart city, it could crash because now collisions are forced to merge, instead game is stable.
5) The better compromise (stability/radius dimension) that i found is a 7,5meters radius.
This radius is enough big and satisfactory to merge building from all sides and stable with all platinum objects and most of user modded buildings. (but still i m testing)

 

Very simple...

1) I opened "all_design.pak" in PAK folder
2) Inside this package, u can find the file "placementrules.cfg"
3) I copied "placementrules.cfg" into folder "...\data\config"

There u can find 2 parameters:
<SnapBuildingDistance> ...at what meters distance buildings snap
<CollisionTolerance> ...meters for reducing collision from building borders

VERY IMPORTANT:
If <SnapBuildingDistance> is bigger than <CollisionTolerance> u dont get any result! Because the snapping-action override ur efforts
making your building to overlap the second building at a distance bigger than collision tolerance.

Perhaps this could be the reason none discovered this secret before.
Infact, before i changed <CollisionTolerance> parameter at a small value without any result,
than i changed it to a big value getting game crashing,
but because i was stubborn playing also with the second parameter, i casually discovered how to make it works.
Later i started experiments to understand how to tune it better

actually i use:
<SnapBuildingDistance>0.5</SnapBuildingDistance>
<CollisionTolerance>7.5</CollisionTolerance>

It seems a mod is not necessary, it seems modified "placementrules.cfg" in folder "...\data\config" override the same file inside
"all_design.pak" file.
So u have also advantage to edit parameter every time u like

Good luck

 

Because some players could not be enough friendly with PAK files, i decided to release a mod.
Enjoy it !

 

yes but u can partially avoid this limit doing so:
1) extract "placementrules.cfg" and copy it into folder "...\data\config"
2) lay down all road in the part of the city where u want to create an historical center on slopes
3) go out game and change <CollisionTolerance> parameter at 19.5
4) come back to game and plop buildings
5) go out of game and change <CollisionTolerance> parameter at 7.5 again
6) play again, once deployed, buildings don't complain about how u plopped them before

...but some building from modders are created with a smaller lot carpet that usual 40x40 or 60x60
so they could crash game if u select them using <CollisionTolerance> parameter at a value >= 8

I tested a bit the game with a value = 7.999 and game seems still stable
