need help spawning a random object

Here is the story...

I have three different models of a destroyed tank.

(actually three edited versions of the wrecked T72 from the AWESOME ICP T72 PACK)

I have a script that will replace a live tank with a destroyed model when it is killed.

(It is actually an edited version of one of the scripts from FAB's "tank effects" scripts)

I am trying to add a line into the script that will replace the killed tank with one of the three destroyed models at random.

If I leave out the "random" stuff, the script works great...(but then all of the dead tanks look exactly the same)

With the "random" line that I attempted to write, it just deletes the killed tank, and shows an error saying "object expected" or something like that.

I dont really understand the "random" command, so I need a little help here.

Thanks in advance

Here is what I am working with:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_TankUnit = _this select 0

; ------------------ Class name (name of model to replace original unit) ------------------------

_targetarray = [icp_t72bwreck,icp_t72bwreck2,icp_t72bwreck3]

_target = _targetarray select (random 3)

; ------------------------------------------------------

_TankUnitX = getPos _TankUnit select 0

_TankUnitY = getPos _TankUnit select 1

_TankDir = getDir _TankUnit

#begining

; ------- remove old Tank and add new one -------

_TankDir = getDir _TankUnit

_TankOld = _TankUnit

deleteVehicle _TankOld

_TankUnit = (_target) createVehicle [-10000, -10000, 10000]

_TankUnit setPos [getPos _TankOld select 0, getPos _TankOld select 1]

_TankUnit setDir _TankDir +180

[_TankUnit] exec "\dkmm_rsc\scripts\dkmm_rsc_veh_burner2.sqs"

exit

"Below is the original version" (the one that works, but only has one destroyed model to choose from)

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_TankUnit = _this select 0

; ------------------ Class name (name of model to replace original unit) ------------------------

_Class = "icp_t72bwreck"

; ------------------------------------------------------

_TankUnitX = getPos _TankUnit select 0

_TankUnitY = getPos _TankUnit select 1

_TankDir = getDir _TankUnit

#begining

; ------- remove old Tank and add new one -------

_TankDir = getDir _TankUnit

_TankOld = _TankUnit

deleteVehicle _TankOld

_TankUnit = (_class) createVehicle [-10000, -10000, 10000]

_TankUnit setPos [getPos _TankOld select 0, getPos _TankOld select 1]

_TankUnit setDir _TankDir +180

[_TankUnit] exec "\dkmm_rsc\scripts\dkmm_rsc_veh_burner2.sqs"

exit

So...anybody got a solution?

You can do it like this:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">

; ------------------ Class name (name of model to replace original unit) ------------------------

_targetarray = [icp_t72bwreck,icp_t72bwreck2,icp_t72bwreck3]

_ran = random 3; _target = whatever

if (_ran <= 1) then {_target = _targetarray select 0}

if (_ran <= 2) then {_target = _targetarray select 1}

if (_ran <= 3) then {_target = _targetarray select 2}

; ------------------------------------------------------

Random will be everything from 0.00000 to 3.00000 so you can't just say random 3 and expect only 1.0000, 2.0000, 3.0000.

Quote[/b] ]if (_ran <= 1) then {_target = _targetarray select 0}

if (_ran <= 2) then {_target = _targetarray select 1}

if (_ran <= 3) then {_target = _targetarray select 2}

I don't think this would work.  The result will always be _targetarray select 2 whenever _ran is <= 3; and whatever if it is > 3

I would do it this way (If you then find another model to make it four models then just add it to the array and all the code will still work):

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_targetarray = [icp_t72bwreck,icp_t72bwreck2,icp_t72bwreck3]

#again

_targetindex = random (count _targetarray)

_targetindex = _targetindex - (_targetindex % 1)

if (_targetindex >= count _targetArray) then {goto"again"}

_target = _targetarray select _targetindex

Quote[/b] ]if (_ran <= 1) then {_target = _targetarray select 0}

if (_ran <= 2) then {_target = _targetarray select 1}

if (_ran <= 3) then {_target = _targetarray select 2}

I don't think this would work. The result will always be _targetarray select 2 whenever _ran is <= 3; and whatever if it is > 3

yes, there was missing something.

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">

if (_ran <= 1) then {_target = _targetarray select 0; goto "j1"}

if (_ran <= 2) then {_target = _targetarray select 1; goto "j1"}

if (_ran <= 3) then {_target = _targetarray select 2}

#j1

You can do it like this:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">

; ------------------ Class name (name of model to replace original unit) ------------------------

_targetarray = [icp_t72bwreck,icp_t72bwreck2,icp_t72bwreck3]

_ran = random 3; _target = whatever

if (_ran <= 1) then {_target = _targetarray select 0}

if (_ran <= 2) then {_target = _targetarray select 1}

if (_ran <= 3) then {_target = _targetarray select 2}

; ------------------------------------------------------

Random will be everything from 0.00000 to 3.00000 so you can't just say random 3 and expect only 1.0000, 2.0000, 3.0000.

I dont understand the "_target = whatever" part

what goes in place of "whatever"?

Quote[/b] ]if (_ran <= 1) then {_target = _targetarray select 0}

if (_ran <= 2) then {_target = _targetarray select 1}

if (_ran <= 3) then {_target = _targetarray select 2}

I don't think this would work.  The result will always be _targetarray select 2 whenever _ran is <= 3; and whatever if it is > 3

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_targetarray = [icp_t72bwreck,icp_t72bwreck2,icp_t72bwreck3]

#again

_targetindex = random (count _targetarray)

_targetindex = _targetindex - (_targetindex % 1)

if (_targetindex >= count _targetArray) then {goto"again"}

_target = _targetarray select _targetindex

I tried that...but it did not work

It just deletes the original tank, and I get this error code:

'(_exp select _i) createvehicle _x l#l' error type any, expected number

here is what I put in the script:<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_TankUnit = _this select 0

_targetarray = [icp_t72bwreck,icp_t72bwreck2,icp_t72bwreck3]

#again

_targetindex = random (count _targetarray)

_targetindex = _targetindex - (_targetindex % 1)

if (_targetindex >= count _targetArray) then {goto"again"}

_target = _targetarray select _targetindex

#begining

; ------- remove old Tank and add new one  -------

_TankDir = getDir _TankUnit

_TankOld = _TankUnit

deleteVehicle _TankOld

_TankUnit = (_target) createVehicle [-10000, -10000, 10000]

_TankUnit setPos [getPos _TankOld select 0, getPos _TankOld select 1]

_TankUnit setDir _TankDir +180

[_TankUnit] exec "\dkmm_rsc\scripts\dkmm_rsc_veh_burner2.sqs"

exit

Try changing the line:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_targetarray = [icp_t72bwreck,icp_t72bwreck2,icp_t72bwreck3]

to

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_targetarray = ["icp_t72bwreck","icp_t72bwreck2","icp_t72bwreck3"]

Also for debugging purposes (ie you take it out when it is all working) I suggest you put a hint in the code as follows:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">hint  _target

#begining

Tried it...didnt work.

Now it either uses the first wrecked model "icp_t72wreck", OR it just deletes the original tank, and does not replace it with anything.

What does the hint message tell you?

Are the following correctly defined:

["icp_t72bwreck","icp_t72bwreck2","icp_t72bwreck3"]

?

Problem corrected!!!

I did, in fact, have my class names defined incorrectly.

(in retrospect, all of the randomization ideas posted by people actually do work)
