set_command() does not work, agen

[Adil]

I remember something like this was brought up before, and the answer was given somewhere.
But not somewhere in the documentation of the function, and forum search fails me.

So the problem: I spawn a few units and try to give then orders, instead of doing orders they just mill around.

Code

Code: Select all

	game.forces.player.ai_controllable=true
	global.runners={
		spawn('behemoth-spitter',-5),
		spawn('small-biter',15),
	}
			--send runners to the finish line
		for _,r in pairs(global.runners) do
			print(r.has_command())--this prints "false"
			r.set_command{
				type=defines.command.go_to_location,
				destination={x=0,y=490},
				distraction=defines.distraction.none
				}
			print(r.has_command())--this prints "true"
		end

Wat do?

They won't instantly start walking when they are given the command, they first have to do the pathfinding, until they have a path they will idle. If the pathfinding takes too long, or there is no path, they will discard the command

Its better to set them all in a unit group, and set the command on the group, which reduces the number of paths the game has to calculate

Well, the problem is that they didn't walk to a position 20 tiles away. The only way I got them do something, is by adding them into a group, then they did try to run to a group position. They did that without a pathfinder though and got stuck in the obstacle on the most direct path.

Is there a way to know, if the path finding took too long or just failed?

In 0.17, you will have some information when a command completes:

Thank you for the idea and fast reply, already looking for a way how to hookup on events (newbie in this language)

(A bit slow after lunch: it will not work, if I dont have that version...)
