Testing for nearby actives without sensors?

[Oreo]

For my main character I test the location of other actives using sensor actives placed around my character.

My predicament is that I have multiple enemies whom I need to test for collision and other stuff. How do I test positions of other objects without having to use sensors on my enemies?

Is there a sort of event sequence that I can use to determine if an active is within a certain number of pixels of another active?

Thanks

You have three main options that I can think of:

1.) Use detector objects as normal - either use one for each object, or run a fastloop/foreach loop to "share" a detector.
This tends to be awkward to implement and/or inefficient, so I don't recommend it.

2.) Use maths - eg. pythagoras' theorum: Distance = Sqrt(((X("A") - X("B")) pow 2) + ((Y("A") - Y("B")) pow 2))
This is fairly simple and very efficient (esp. with very large objects), but obviously you don't get pixel-perfect collision detection.

3.) Use embedded detectors - http://www.create-games.com/article.asp?id=1639
This is fairly simple and efficient, and it gives you pixel-perfect collision detection, so its my preferred method in most cases.

Use the AdvanceDirection extencion

Hmm...... I have a closest enemy example (Don't remember who made it). Do you think that will help? It basically supposed to find the closest enemy using distances & stuff.

Hm, how can I get the Advanced Direction extension (or whatever it's called)? I'd like to get it because it won't let me view N64Mario's example without it.

The Advanced Direction Object is in the Extensions pack 1

Other than that, I recommend downloading a program called extension view, made so that you can search for (and download) any extension out there Here is the link for that: http://www.clickteam.com/epicenter/ubbthreads.php?ubb=showflat&Number=245084#Post2450 84
