Make ground units follow roads

[RagnarDa]

My mission edition scripting skills is getting a bit rusty... I am trying to make a ground unit group dynamically move and use the roads on the way. How?

 

Here's what I got now:

 

local _mission = { 
           id = 'Mission', 
           params = { 
               route = { 
                   points = { 
                       [1] = {
                               action = 0,
                               x = 684878.31512451,
                               y = -285936.0,
                               speed = 25,
                               ETA = 100,
                               ETA_locked = false,
                               name = "Starting point", 
                               task = nil 
                       },
                       [2] = {
                               action = 0,
                               x = 688961.42410916,
                               y = -283350.27609121,
                               speed = 25,
                               ETA = 100,
                               ETA_locked = false,
                               name = "Destination point", 
                               task = nil 
                       },  
                   } 
               }, 
           } 
       }
local _controller = Group.getByName("TestGroup"):getController();
Controller.setOption(_controller, AI.Option.Ground.id.ALARM_STATE, AI.Option.Ground.val.ALARM_STATE.GREEN)
_controller:setTask(_mission)

Help greatly appreciated!

I have a very messy way of doing this by having the group move to random point in random zone when it enters a zone on the map spammed with zones. It's awful.

 

I look forward to a more civilized way.

Action needs to be "On Road"

 

Also need to add a type = "Turning Point"

 

 

Its worth noting that it is best if the on road points given are actually on a road. If the on-road WP is off a road the AI will usually try to find the nearest road to that point, but it doesn't always work.

you can as well use Land.surfaceType function to check if it is a road or not. And if not iterate over x/y until find one. I'm not at home right now, don't have my code in front of me, but that is an idea basically.

Got it working! Thank you so much guys!
