This action will perform a conditional test on group variable. This action should take 1 sub action.
If the condition is matched then the sub action is executed. The conditions expression must match the folowing pattern :
<local_variable> <operator> <local_variable|foreign_variable|constant_value>
operator can be one of '<', '>', '=', '!=', '<=', '>='
Each group come with a set of 4 variables with id 0 to 3.
Locals variables are the variables of the current group, they are expressed with a 'v' followed by the variable id (0-3). eg : v0.
Foreign variables are accessible only if the group name is unique in the manager or the world.
Foreigns variables are variables that come from another group. They are expressed with the group name followed by a colon ':' then followed by a local variable identifier (v). eg : group_1:v2.
Constant value are floating point numerical expression in base 10.
