Custom Array not working... list of vehicles

[TheOakster]

Hello,

I have the following code in a script:

Code: [Select]

_veh = ["SKODA","SKODARED","SKODAGREEN","SKODABLUE","TruckV3SCivil"]
car = nearestobject[ch2,"_veh"]

ch1 domove getpos car
ch2 domove getpos car
But it doesnt work, however if I do this then it does:

Code: [Select]

car = nearestobject[ch2,"skodared"]

ch1 domove getpos car
ch2 domove getpos car
Is there something wrong with how I have defined the array, or do arrays not work for nearestobject?

or do arrays not work for nearestobject?

correct.

what you will have to do is run a loop to determine which types of vehicle are near to ch2, and if there's more than one, determine which is closest. something like

Code: [Select]

_veh = ["SKODA","SKODARED","SKODAGREEN","SKODABLUE","TruckV3SCivil"]

_i = 0

#loop

call format ["_car%1 = nearestobject [ch2, (_veh select _i)]", _i]

_i = _i + 1
?not (_i == (count _veh)) : goto "loop"

_dist = 1000
_i = 0
#loop2

call format ["_d = _car%1 distance ch1", _i]
? _d < _dist : _dist = _d; call format ["_closest = _car%1", _i]

_i = _i + 1
?not (_i == (count _veh)) : goto "loop2"

ch1 domove getpos _closest
what this does is loop through the array of vehicles, checking if there are any near ch1. if there is a vehicle of that type nearby, it is assigned a variable (_car1, _car2, _car3, etc).

then another loop is done checking which of the _cars is closest to ch1. the closest car is assigned the variable _closest. ch1 is then told to move to it.

untested, but give her a whirl

what you will have to do is run a loop to determine which types of vehicle are near to ch2, assign them to variables and then determine which is closer.

That easy huh?  :'(

I will be back soon then....

nearestObject only works on a position in x,y,z format or an object......[position, "type"] or [object, "type"]

Consult the command reference there is a link on the Home page.

In case you cant find it,    here.

nearestObject  here.


EDIT:  That bedges , getting to quick on the type these days.

@ bedges - trying now

@planck - I was using the comref when I was trying to work out how this was used, but i just wondered if it would work

@bedges

Nope that doesnt work, there are no errors given, ch1 just doesnt move to the car.

[bedges]

testing now.

EDIT

right. the call format doesn't seem to like local variables. global variables work just fine. the ammended script thus reads:

Code: [Select]

_veh = ["SKODA","SKODARED","SkodaGreen","SKODABLUE","TruckV3SCivil"]

_i = 0

#loop

call format ["car%1 = nearestobject [ch1, (_veh select _i)]", _i]

_i = _i + 1
?not (_i == (count _veh)) : goto "loop"

_dist = 1000
_i = 0
#loop2

call format ["d = car%1 distance ch1", _i]
? d < _dist : _dist = d; call format ["closest = car%1", _i]

_i = _i + 1
?not (_i == (count _veh)) : goto "loop2"

ch1 domove getpos closest

Cheers bedges that works

... the call format doesn't seem to like local variables...

Code: [Select]

...
call format ["d = car%1 distance ch1", _i]
...

I was just wondering if the reason that:

Code: [Select]

call format ["_d = car%1 distance ch1", _i]does not work is because _d needs to be defined before the code string is executed?
i.e.

Code: [Select]

_d = 0
call format ["_d = car%1 distance ch1", _i]
Can't check right now as I am at work but am still curious.

A new tute on the finer points of the call command and the call format idiom, and numerous examples of their possible uses would be good.  This thread is a primer.

   That thread just scares me....!!
