How to prevent AI from moving?

[PhantomJedi]

How would I go about preventing the AI from moving whatsoever? I have figured out how to do this with the AI leader, but not with the AI units.

[Velensk]

One way you could do it is by giving all the AI units you don't want to move an [object] which sets their move to 0.

Ok, I tried that, and I'm pretty sure my coding isn't correct:

Code: Select all

[modifications]
		[object]
			[effect]
				movement_set=0
			[/effect]
		[/object]		
[/modifications]

Edit:

I changed the code to:

Code: Select all

[modifications]
		[object]
			[effect]
				apply_to=movement
            set=0
			[/effect]
		[/object]		
[/modifications]

It doesn't work either.

Code: Select all

[status]
guardian=yes
[/status]

Try this maybe?

I disclaim having any major knowledge of AiWML, but, theoretically, including…

Code: Select all

[ai]
    [avoid][/avoid]
[/ai]

…in the relevant [side] tag should forbid that side’s AI from moving any units anywhere, except for its leader, who you say you have already prevented from moving.

One simple method:

Code: Select all

[event]
    name=side 2 turn refresh
    first_time_only=no

    {MODIFY_UNIT side=2 moves 0}
[/event]

You can add a [filter_condition] if you don't want it to always be active.

Thank you all for your suggestions. I will try those, and see if they work with what I am attempting to do.

The easiest method is setting [side]controller= to null. It can be switched back and forth by [modify_side]controller=, and doesn't need a side turn event to run and modify unit movement points on every turn. However, setting controller=null makes the engine ignore any side turn (and similar) events for the particular side, so don't be surprised that they aren't fired if you have any.
[side][ai]ai_algorithm=idle_ai works, but cannot be modified, due to a bug.
A third pseudo-method is to take away all gold an income and/or the recruit list The remaining leader will just sit in his keep and do nothing, with the default ai.

[PhantomJedi]

Well, the AI has units, and I have prevented the leader from moving; I just need the units to stand still until an event is fired that will make them aggressive and let them move.

I had this same problem once. As it happens, it was my first forum post. I wanted to keep Ivan The Blackheart, a bandit in Fall of Trent, from moving until the players got near. Amusingly, zookeeper offered the same solution as he's done here. However, the method I ended up using was to make Ivan unable to move on any of the surrounding terrain.

Code: Select all

    [object]
		silent=yes
		duration=forever
		[filter]
			name="Ivan The Blackheart"
		[/filter]
		[effect]
			apply_to=movement_costs
			replace=true
			[movement_costs]
				flat={UNREACHABLE}
			[/movement_costs]
		[/effect]
	[/object]

You can then reallow movement with this:

Code: Select all

    [object]
		silent=yes
		duration=forever
		[filter]
			name="Ivan The Blackheart"
		[/filter]
		[effect]
			apply_to=movement_costs
			replace=true
			[movement_costs]
				flat=1
			[/movement_costs]
		[/effect]
	[/object]

You can always put more terrain types inside the [movement_costs] tag. If you don't want to worry about their surrounding terrain, you can prevent them from moving on all possible terrain types.

Code: Select all

   [object]
		silent=yes
		duration=forever
     [filter]
         whatever=whatever
     [/filter]
		[effect]
			apply_to=movement_costs
			replace=true
			[movement_costs]
				deep_water={UNREACHABLE}
				shallow_water={UNREACHABLE}
				reef={UNREACHABLE}
				swamp_water={UNREACHABLE}
				flat={UNREACHABLE}
				castle={UNREACHABLE}
				sand={UNREACHABLE}
				forest={UNREACHABLE}
				hills={UNREACHABLE}
				mountains={UNREACHABLE}
				village={UNREACHABLE}
				cave={UNREACHABLE}
				frozen={UNREACHABLE}
				unwalkable={UNREACHABLE}
				impassable={UNREACHABLE}
				fungus={UNREACHABLE}
			[/movement_costs]
		[/effect]
	[/object]

Hope that helps.

Ok, the [side] controller=null method will not work. It doesn't spawn the leader, and like was said, none of the events involving the side fire. I'll try the object method again.

Edit:

The object method still didn't work.

Code: Select all

					[unit]
						type=Villager
						id=Eostysu
						name=_"Eostysu"
						x=17
						y=14
						side=2
						random_traits=no
						[modifications]
							[object]
          						silent=yes
          						duration=forever
          						[filter]
          							id=Eostysu
          						[/filter]	
          						[effect]
            						apply_to=movement_costs
             						replace=true
             						[movement_costs]
                						deep_water={UNREACHABLE}
                						shallow_water={UNREACHABLE}
                						reef={UNREACHABLE}
                						swamp_water={UNREACHABLE}
                						flat={UNREACHABLE}
                						castle={UNREACHABLE}
                						sand={UNREACHABLE}
                						forest={UNREACHABLE}
                						hills={UNREACHABLE}
            							mountains={UNREACHABLE}
            							village={UNREACHABLE}
            							cave={UNREACHABLE}
            							frozen={UNREACHABLE}                 							
            							unwalkable={UNREACHABLE}
                						impassable={UNREACHABLE}
                						fungus={UNREACHABLE}
             						[/movement_costs]
          						[/effect]
       						[/object]
							{TRAIT_LOYAL}
						[/modifications]
						{IS_LOYAL}
					[/unit]

Yes, with controller=null you have to spam the leader by hand with [unit]canrecruit=yes.

Did setting the moves of all side units to zero in a turn refresh event not work?

Another alternative, you can end the ai turn as soon it starts

Code: Select all

[event]
   name=side 2 turn
   first_time_only=no
   [end_turn][/end_turn]
[/event]

Add an filter_condition if it should not fire all the time.
