How do I make a homing projectile when there are multiple possible targets?

In my game, the player has some weapon choices, one of which is a (non-functioning) homing missile launcher. Because i'm making my game in endless style, i use a timer to spawn enemies, which means there are always multiple enemies on screen. The missile needs to:

1. Set its target

2. Follow its target till collision

Any help would be appreciated

1. Select target using Line of Sight behavior or some other method, make sure to pick just one enemy instance (for example, with "pick nearest" event).

2. Save target UID in missile's instance variable.

3. Navigate to the target with Pathfinding behavior. If the enemy is moving, you'll have to refresh the path every 0.5 seconds or so.

Here's another example..

Like you said.. you have to select one target, once a target is selected you can then move towards the target... instead of using pathfinder you can restrict how fast it can turn by using anglelerp like in this example.. sometimes it overshoots and turns around...

Hope it helps..
