Guided Missle Lock - Ropeburn - Dec 11, 2010 01:32 PM
I'm adding guided missles to my game and would like them to lock onto a particular entity in my world. Parsing through the list of entities is not a problem. Rather, I'd like some feedback, thoughts or ideas for algorithms to acquire the lock. Thanks.[/align]

forward 180° up to a certain range?

Factoring in range to target might be a good idea. I'm not a guided munitions expert or anything, but I was under the impression that radar lock had a range beyond which is wasn't able to achieve good tone.

Yes. I was thinking of casting a ray for the view and seeing if any lockable entities were within a set range. I'm guessing that is how it is done.

Unless you're planning on having shedloads (read: 1,000+) lockable entities in you entire game world, worrying too much about this algorithm is just premature optimization. I find that's it's a lot easier to optimize when you have something that's running slow, instead of optimizing before it's going slow.

I've implemented this a couple of times before. Are you looking for help with a particular part of the algorithm, or are you not sure of the general approach to take?

I'm looking for a general approach. I'll be able to hande it from there.

As I recall, mine worked something like this:
