Strange Ruby String Selection
- by Daniel
The string in question (read from a file):
if (true) then
{
_this = createVehicle ["Land_hut10", [6226.8901, 986.091, 4.5776367e-005], [], 0, "CAN_COLLIDE"];
_vehicle_10 = _this;
_this setDir -2.109278;
};
Retrieved from a large list of similar (all same file) strings via the following:
get_stringR(string,"if","};")
And the function code:
def get_stringR(a,b,c)
b = a.index(b)
b ||= 0
c = a.rindex(c)
c ||= b
r = a[b,c]
return r
end
As so far, this works fine, but what I wanted to do is select the array after "createVehicle", the following (I thought) should work.
newstring = get_string(myString,"\[","\];")
Note get_string is the same as get_stringR, except it uses the first occurrence of the pattern both times, rather then the first and last occurrence.
The output should have been: ["Land_hut10", [6226.8901, 986.091, 4.5776367e-005], [], 0, "CAN_COLLIDE"];
Instead it was the below, given via 'puts':
["Land_hut10", [6226.8901, 986.091, 4.5776367e-005], [], 0, "CAN_COLLIDE"];
_vehicle_10 = _this;
_this setDir
Some 40 characters past the point it should have retrieve, which was very strange...
Second note, using both get_string and get_stringR produced the exact same result with the parameters given.
I then decided to add the following to my get_string code:
b = a.index(b)
b ||= 0
c = a.index(c)
c ||= b
if c 40 then
c -= 40
end
r = a[b,c]
return r
And it works as expected (for every 'block' in the file, even though the strings after that array are not identical in any way), but something obviously isn't right :).
