Title: group dead?
Post by: 456820 on 23 Dec 2004, 18:34:31

how do you check if a group is dead or a vechile i usually put "(count units groupname == 0) and (not canmove vechile name) they used to work im sure everything is correct but when i use it and i kill all the groups and vechiles it doesnt activate the trigger? so is there a different way of checking if agroup or vechile is down wich will activate a trigger?

perhaps just a syntax problem when you tried it? idk
for the vehicle, i noticed your syntax is wrong:
not (or !)...
not(canmove vehicle) or
!(canmove vehicle)
try it

hmmm... i have no clue what the problem is, unless you recently got a new version and it doesn't use the not command (it is considered a command, right?) but rather the !
just a wild guess, but i doubt it

i dont think so but if i 4x the game and wait for ages then the trigger activates i was thinking how it says (count units) means when the player sees all the units dead but i dont think so  and the (not canmove) one works most of the time but still doesnt all

count units can take ages to recognise that units are dead especially if the group has been wiped out.  Better is something like

{alive _x} count units <groupname>

But that was pretty much Triggerhappy's first post so if you are using that I don't see what the problem is.

is the {} and <> needd or does it have to be {alive_x} count units <groupname> wat is the x for

type it exactly as shown except instead of <groupname> just put the name you have given to the group   I put <> around it to show that is is not an instruction.

_x is a reserved variable that takes on each of the values in the array units <groupname> in turn.  

To explain the instruction in full:

<groupname> is the name you have given to a group
units <groupname> is an array of all the units in the group
count units <groupname> is the number of units in the group

But note that it can include dead units that have not yet been removed from the group.

Putting {alive _x} in front of the count tells OFP only to count units that are alive

In general:
 {condition} count array

will count the number of units in the array for which the condition is true.

oh ok thanks

hang on so wouldnt you change the x to 0 so it say's "groupname number of people alive = 0 so therefore activates the trigger"

Title: Re:group dead?
Post by: Triggerhappy on 24 Dec 2004, 19:06:21

no, you would do:
{alive _x} count units <groupname> == 0

Thank you Triggerhappy.

Let us give a worked example so there can be no further misunderstanding.

In the init field of your group leader put:
Grp1 = group this
This gives your group the name Grp1

In your trigger's activiation field put:
{alive _x} count units Grp1 == 0

This is topical at the moment.  Have a look at:
