Random movement of units

[Kal_Ultor]

I try to make a unit move randomly, so that no player or ai moves the unit but it will move 5 hex on a random path. I tried this:

Defining unit

Code: Select all

[event]
        name=prestart

        [unit]
            id=fireship
            type=boat
            x,y= 10,10
        [/unit]
    [/event]

Making an event when the ship is moved

Code: Select all

    #move ship randomly
    [event]
        name=turn end

        [move_unit]
            id=fireship
            check_passability=yes
            force_scroll=yes
            dir={MOVEMENT}
        [/move_unit]
    [/event]

The Macro

Code: Select all

#define MOVEMENT
[set_variables]
    name=dir_fireship
    [value]
        rand=N,NW,NE,E,W,S,SW,SE
    [/value]
    [value]
        rand=N,NW,NE,E,W,S,SW,SE
    [/value]
    [value]
        rand=N,NW,NE,E,W,S,SW,SE
    [/value]
    [value]
        rand=N,NW,NE,E,W,S,SW,SE
    [/value]
    [value]
        rand=N,NW,NE,E,W,S,SW,SE
    [/value]
[/set_variables]
#enddef

Any ideas, is my macro flowed (i guess but I don't know why/ how to do it better)

MOVEMENT is called as value of dir key, so it should return some text value. Currently you have
dir=[set_variables] and later on try to close tag [/set_variables] which was never opened, since [set_variables] is value of dir, it is not treated as opening tag.

After solving syntax issues we get to

Code: Select all

[set_variables]
    name=dir_fireship
    [value]
        rand=N,NW,NE,E,W,S,SW,SE
    [/value]
    [value]
        rand=N,NW,NE,E,W,S,SW,SE
    [/value]
    [value]
        rand=N,NW,NE,E,W,S,SW,SE
    [/value]
    [value]
        rand=N,NW,NE,E,W,S,SW,SE
    [/value]
    [value]
        rand=N,NW,NE,E,W,S,SW,SE
    [/value]
[/set_variables]
[move_unit]
	id=fireship
	check_passability=yes
	force_scroll=yes
	dir=$dir_fireship[0].rand
[/move_unit]

However there is nothing about randomness so far. You could use [set_variable] with rand to get random data.

I've made something like that, but without a route. I'm using teleport to teleport the unit and the animate function of teleport that let it appear as if it is moving. Note - the unit I move has the id "Mover".

Code: Select all

[store_unit]
									variable=wanderermove
									[filter]
										id=Mover
									[/filter]
								[/store_unit]

								[set_variable]
									name=wandererchangex
									rand=-1..1
								[/set_variable]

								[set_variable]
									name=wandererchangey
									rand=-1..1
								[/set_variable]

								[set_variable]
									name=wanderx
									value=$wanderermove.x
									add=$wandererchangex
								[/set_variable]

								[set_variable]
									name=wandery
									value=$wanderermove.y
									add=$wandererchangey
								[/set_variable]

								[unstore_unit]
									find_vacant=no
									variable=wanderermove
								[/unstore_unit]

								[clear_variable]
									name=wanderermove
								[/clear_variable]

								[teleport]
									[filter]
										id=Mover
									[/filter]
									x=$wanderx
									y=$wandery
									animate=$movementsetting
								[/teleport]
								

You can combine it with a while loop to make the boat walk several steps or if the units are called Boat1 Boat2 and so on, you could make a while loop that moves several boats or units one after another.
