Understanding WNT Files

[thorberg]

Hi, I'm from KotF (codename Senate Flounder) and I need help understanding the syntax of botroute files, specifically what the numbers of a given line represent.  We're attempting something new, and I require this knowledge to press forward.  Thanks in advance.

Hi,

 

It seems to be the coordinates of the waypoints of the map.

It's better to work on it ingame, more practical and more visual.

 

Some useful functions for a .cfg file or to type in the console :

seta developer 1
seta bot_wp_edit 1

bind Q bot_wp_add
bind E bot_wp_rem
bind R bot_wp_save

Making the file in JA is not the issue; I need to extract the coordinates in the file for other purposes and I need to know the breakdown of each of the numbers for it to work.

Basically a list of nodes (id, flags, weight and coordinates) and each node lists its neighbouring node's IDs. I think. Haven't looked at an actual .wnt file

That seems to check (although I don't know what weight would have anything to do with anything) but what about the numbers after that?

 

Sample entry:

17 4194304 0.000000 (-478.067963 100.311096 -7.875000) { 37 38 39 40 41 42 } 32.000000

It's the neighbouring node's IDs i.e. the most nearby points. The ID for this node is the first number in the line.

 

"weight" is a term used in graph theory usually to explain the cost of traversing from one node to another (e.g. distance, "difficulty")

The last number in the line appears to be the distance from this node to the next (precomputed)
