Moving units without waypoints

[Rocko Bonaparte]

I've seen some work done in assigning movement to units based on code, and not by using fixed waypoints.  The general consenus has been to make missions more flexible by making waypoints dynamic.

I found a tutorial for assigning units to move to certain positions using markers, and there were some waypoints involved as well.  It wasn't what I was hoping.  I had already written a script for moving a unit along some path.  The idea was that it would ultimately turn into a state machine, and the unit would change its mission as different conditions changed.  For now, though, it was just cycling a sequence.  

Here's a simplified version of what I had written:

Code: [Select]

_player_name = _this select 0

_player = call format["%1",_player_name]
_pos = "Logic" CreateVehicle [9632.477539,29.834999,3865.032227]

#Move1
_pos setPos [9632.477539,29.834999,3865.032227]
_player move (position _pos)
hint "Told target to move"
@((_player distance _pos) < 2.0)

#Move2
hint "Moving to second target"
_player doMove [9708.595703,29.834999,3865.032227]
_pos setPos [9708.595703,29.834999,3865.032227]
@((_player distance _pos) < 2.0)

#Move3
_player doMove [9709.749023,29.834999,3936.538574]
_pos setPos [9709.749023,29.834999,3936.538574]
@((_player distance _pos) < 2.0)

#Move4
_player doMove [9627.863281,29.834999,3933.078613]
_pos setPos [9627.863281,29.834999,3933.078613]
@((_player distance _pos) < 2.0)

goto "Move1"

I have a few different ways of moving shown above, with none of them working.  I assign a solider as its own group to this script in init.  The unit will just stand around, although I get the message "Told target to move." I've tried commandMove, doMove, and just plain move.  I've been wrapping the position in an object because the move commands don't really like that array.  If the script got any further than the first move, it should actually error.  Still, you should be able to see what I am trying to do.

It doesn't seem like I fully understand how the move commands actually work.  The OFP comref is lacking in that regard--the only distinction it seems to make above them is how they are relayed over the radio.

Can I use the code above in a certain way?  Do I NEED markers and waypoints?

i think your problem is right here:

_player = call format["%1",_player_name]

you are turning the units name into a string, which can't be used with the move commands (i think)

i would eliminate that line, and change every _player into _player_name

and that should work

[Rocko Bonaparte]

I can't test it right now, but I can already tell that makes me worried.  I'm going through all that trouble because the script will ultimately be for multi-player.  The player that is the subject of that script will inevitably die and respawn.  Given that circumstance, would using _player_name still work?

[Rocko Bonaparte]

i think your problem is right here:you are turning the units name into a string,

I just tried this and it turns out I am not turning the unit into a string; I'm turning the string into a unit.  doMove complains that I am using a string if I use _player_name as my object.  Needless to say, the person still won't move.

Edit: I have the target of the script be me now.  I'm assuming I'd get a yellow box with "MOVE" printed by it on my HUD when the move command was given.  It doesn't happen; whether I use move, doMove, or commandMove.  

Something that may be important to know is I'm passing the name of the unit into my script.  I wonder if it's something just basic.  I tested killing a person in front of my by setting their damage to maximum in the script, and it looks like the script is getting its targets correctly.  People just won't move when told to for something reason.

Whaaat?

Try changing

_player_name = _this select 0
to
_player = _this select 0


_player = call format["%1",_player_name]
to
_player = call format["%1",name _player]


_player move (position _pos)
to
_player move getpos _pos

[Rocko Bonaparte]

OK here's what I tried:

Code: [Select]

? not local Server : exit
_player = _this select 0

_player = call format["%1", name _player]

_pos = "Logic" CreateVehicle [9632.477539,29.834999,3865.032227]

#Move1
_pos setPos [9632.477539,29.834999,3865.032227]
_playerobj move (getpos _pos)
However the "call format" line generates the error "Error name: Type String, expected Object."

If I just take it out and use:

Code: [Select]

? not local Server : exit
_player = _this select 0

_pos = "Logic" CreateVehicle [9632.477539,29.834999,3865.032227]

#Move1
_pos setPos [9632.477539,29.834999,3865.032227]
_player move (getpos _pos)
There is no error, but the target unit doesn't move either.  Just stands there with his gun out.

edit: Using "_player" in last line, not "_playerobj"

[Planck]

Where is _playerobj defined?

I can't see it mentioned in the script. apart from the last line.

Also, you probably don't need the line:

_pos setPos [9632.477539,29.834999,3865.032227]

because _pos is already at this position when you created it with this line:

_pos = "Logic" CreateVehicle [9632.477539,29.834999,3865.032227]

[Planck]

Almost forgot........the move command is for moving groups, try domove instead.

It looks like you caught something.  I've narrowed the script down to just this:

Code: [Select]

_player = _this select 0

_pos = "Logic" CreateVehicle [9632.477539,29.834999,3865.032227]

_player doMove (getpos _pos)
And it complains that _player is a string, not an object.

I call this in my init.sqs:

Code: [Select]

["TestJeep"] exec "waypoints.sqs"

And "TestJeep" is referred to my mission here:

Code: [Select]

      class Item1
      {
         side="WEST";
         class Vehicles
         {
            items=1;
            class Item0
            {
               position[]={9662.691406,29.834999,3908.917236};
               id=1;
               side="WEST";
               vehicle="SoldierWB";
               leader=1;
               skill=0.600000;
               text="TestJeep";
            };
         };
      };
It looks like I have a more fundamental problem here -- properly passing that value in.  As a string, I've been able to set the damage of the thing and have it die, but it doesn't want to accept the move command.  I'm guessing some commands are more flexible than others.  What can I do?

[Triggerhappy]

in the mission file everything has quotes around it. get rid of the quotes when you exec the script

"This" is a string
This isn't

[Rocko Bonaparte]

Do you mean to get rid of them in init, or in the mission?  First, I tried:

Code: [Select]

[TestJeep] exec "waypoints.sqs"That didn't work, so I tried taking the quotes of the text field.  The soldier still just stands there.  I tried doMove and move, and neither worked.  :-\

BTW, "TestJeep" right now is a solider, not a jeep.

[Triggerhappy]

unless you are working in the mission.sqm file, names of units are not in quotations.
quotes words are a string, which is used for hints, titletext, sidechats

[Planck]

So, your soldier is named TestJeep in his name field?

Is TestJeep the player, or is he an AI soldier?

If he is the player, of course, you can't force him to move anywhere.

TestJeep is an AI soldier.  I tried it on the player as well to see if anything came up on the HUD.  Nothing showed up using commandMove, doMove, or move.

[Planck]

I think your height value in this line is a little suspect:

_pos = "Logic" CreateVehicle [9632.477539,29.834999,3865.032227]

The second value in that list looks more like a reasonable height value.

Try swapping them about.


Planck

[Fragorl]

Are you copying positions from mission.sqm? as Planck says, they are out of order.

I think you have to be in cadetmode to see commandmove objectives in your hud.

As for the main script, domove should work fine provided an object that can move (like a soldier or crewed tank) is called, not a string or anything else.

So

Code: [Select]

;called as [testjeep] exec "waypoints.sqs"
_soldier = _this select 0
;same as: _soldier = TestJeep
_pos = "logic" createvehicle [wherever]
_soldier domove getpos _pos
;Other stuff

Ignore the quotes in mission.sqm as they are just misleading

[Rocko Bonaparte]

Yeah somebody from the BIS forums told me the coordinates had to be swapped.  That fixed it.
