Editing navmesh file (.nvm)

[sarkoplata]

Lately i've been messing with the navmesh files to add some impassable objects to the map or make impasssable objects passable.
In short i am trying to change the collision of the objects located on the map.

I am using the navmesh structure released by @ at github:


for example i want to make bagh_barricade01.bsr passable:


despite the documentation I noticed that impassable objects have Collision -1 and passable objects have Collision 0.

However changing these collisions are somehow not enough. nothing happens. If i make other changes, they work (if I increase the X pos of the barricade by 100, the impassable terrain is moved 100 units or so)

Any hint would be much appreciated

The "collision" seems to be an indicator only.
It really comes down to [Compound(*.cpd)]->CollisionResource (*.bsr)->CollisionMesh(*.bms)->Collision(pointer.Collision).

You could replace the object (navmesh\object.ifo) with

res\bldg\europe\constantinople\euro_constan_bl_04.bsr

to make it walkable.

^ps; each and every object you replace will be walkable if you do it from object.ifo so before doing that check if there's only 1 object entry of that kind. You don't want a bugged map xd

Therefore add your own entry to object.ifo and change desired objectID in the navmesh to your newly created entry.

Thanks for the help.
I've tried to give hardness to objects before this and failed as well. Lets say I added something hard to the .o2 file and it's visually shown in the game. However, when I add an entry to the navmesh file with the hard bsr, it's still passable. Im using the same uniqueIDs as well. What could cause it then?

Lemme give you another hint that would make your life harder xd Adding the entry is not enough. You have to also link that new entry to the zones, right below the object entry list there's a linking block. You gotta find your way through adding it there. I'd really give you exact info but sadly I am not on my pc and I won't be for a few months. But I am sure that's what you're missing.

That really made my life harder xd

There are 3 zone blocks after the entry list. Im still trying to relate them

Well,basically you only need the first zone block,because those are the zones that contain the entities,as far as I remember third zone block is terrain collision,and don't remember what the second zone block was for ^_^

It took me some time to add collision to map objects (mostly due to my retardiness) but I finally achieved my goal! Thanks everyone, especially Daxter

any one got the tool and can upload it? pleas

[sarkoplata]

Some people were asking me for this tool, even though I told them it was pure garbage. Maybe it has a use for you though. I just stumbled upon the source when I was checking some old hard drives.

Well, he shared it for people that wanna learn, not to use.

Also, if you knew how the tool reads the navmesh files, then ofc you should know how to edit them.

I don't remember what it did lately, could be an experimental thing i lately made that causing the error, cuz it was working fine. Check the source code.
