Ruby Questions

I am trying my hand at modifying a script and I can't figure a few things out.



targ = find_target
echo targ
beast = @target_list.index(targ)


This is working within the megatron script. The echo works appropriately, so I know the find_target function is working and I know targ is being defined. I also know that target_list contains a value equal to [i]targ]/i]

Beast however does not work, it is nil. Instead of returning an array index number.

Second problem.



echo targ //prints kobold
echo @target_list[0] //prints kobold

if @target_list[0] == targ then
message("Match")
else
message("No Match");
end


It gives me No Match, why?

I think I must be missing some syntax rule for working with arrays in ruby.

It can only be returning nil because targ is not in @target_list. Looking at megatron, it appears that @target_list is an array of strings, and find_target returns a GameObj object. You'll probably need to do:

beast = @target_list.index(targ.noun)

Although, I'm a little suspicious as to how knowing the index would be useful.

Second problem is the same as the first. targ is not a string, it's an object of the GameObj class. When you echo it, it attempts to convert it into a string, which amounts to giving only the noun. That's why they appear to be the same.

Thanks, I get it.

How it'd be useful?

Well suppose I changed the settings input to allow you to specify attack commands for each critter in your target list individually whereby the first critter corresponds to the first attack command, the second to the second, etc.

Once find_target finds the target I then access the index to see which it is, and then access the corresponding attack command sequence, and I've now got customized attacks per critter.

There would be easier ways of doing that if I knew ruby as well as I know php or something else, but since I've got about 2 days of experience with ruby now I figured that would be the easiest method, especially since I would have to edit as little of the existing script as possible.
