Okay so I am making homing attack in my engine however I can't find a way to make it work depending on the closest detected enemy. How do I achieve this? "Without Extensions".

I have included the MFA, in-case helpful : http://dl.dropbox.com/u/5505419/MFA/SonicBaseEngine_Homing.mfa

Thanks in advance. :3

Don't quite understand what you're trying to say there. Care to elaborate? Bare in mind I want to not use any extensions.

enemy - set alterable value A to distance beetween enemy and player
without extensions you need an article like this for distance, i suck at math so...: http://www.create-games.com/article.asp?id=1898


2nd event
picking an enemy with lowest alt A can be done is several ways, you can for instance do it with a loop
set global A to 999
enemy spread value 0 in value B

3d event
start loop"a"
enemy value B = loopindex"a"
enemy value A < global A
-
set global value A to enemy value A

4th event
and then just pick the enemy with
enemy value A = global A
pick at random so it picks only one in case if there are two objects with the same value

He is saying make an event that sets the enemy's alterable value a to the distance between itself and your character, and then in the event where the player activates the homing attack, run a fastloop a number of times equal to the number of enemies, and on each loop, compare the alterable value a of the object whose other value (a value you'll spread a value in) is equal to the index of the fastloop, and store that value in a counter or some value on the player character only if it is within a certain distance. At the end, send Sonic towards that enemy.

EDIT: He got it while I was writing.

I think I get it. Not exactly sure....I also suck at maths haha. Thanks for the input so far though guys. Maybe if it was made into the mfa it would probably make a lot more sense to me.

Seriously, just use the extension ("Select Object" extension) - it will make things a lot easier for you.
And do a search while you're at it - this has been discussed so many times before...
