Homing missile

Hello

I am in the process of porting my game from Game Maker to C2 and all has been smooth so far except for this issue

I need the player to shoot an object which will lock on to the nearest enemy of a specific type and then move towards it until they collide

So basically i need to
1. Find the nearest enemy
2. Make sure the missile follows it
3. Make the missile continue in a straight line if that enemy is destroyed before it hits its target

Apologies if this is already covered somewhere but i looked through the FAQ and did a search in this section but didn't find anything i could use

Any help will be much appreciated

Thank you for your reply

I don't understand

I am using bullet behaviour but i don't see anything about pick closest target in it's behaviour
I am hopeless at trigonometry so i was hoping i could do this some other way. Like in Game Maker there is a move towards behaviour you put in the every tick event

What am i missing?

You are awesome!

That's exactly what i need

Thank you, thank you, thank you

If you want the missiles to behave a bit more realistically, I would suggest, instead of setting the angle straight towards the object, every tick set the angle to: anglelerp(rocket.angle,angle(rocket.x,rocket.y,target.x,target.y),dt*somespeedfactor)
