Old Notes (temporary):
returns the number of elements in the array for which the '''condition''' is true.  If {condition} is not specified then the number of elements in the array is returned.


'''Example:'''
(1) Use this to calculate how many "M16" mags a soldier has left. ("_x == {M16}" count [[magazines]] soldier1)
(2) Take care when using count to determine how many units are left alive in a group: count units [[group]] [[player]] or count units groupname Will return the number of units the leader of the group thinks are alive. If some units have been killed out of sight of other members of the group then it may take sometime for this to be the actual numbers in the group. To determine exactly how many units are really alive in a group use: {[[alive]] _x} count units [[group]] [[player]] or {[[alive]] _x} count units groupname


'''count''' [0, 1, 1, 2, 3, 3] ...... Result is 6

Old Notes (temporary):

(1) Use this to calculate how many "M16" mags a soldier has left. ("_x == {M16}" count magazines soldier1) (2) Take care when using count to determine how many units are left alive in a group: count units group player or count units groupname Will return the number of units the leader of the group thinks are alive. If some units have been killed out of sight of other members of the group then it may take sometime for this to be the actual numbers in the group. To determine exactly how many units are really alive in a group use: {alive _x} count units group player or {alive _x} count units groupname
