need help on creating this missile launching thing.

I need a script where the enemy would shoot a homing missile to my main character like so (armorgames.com/play/2963/dodge) with speed, power, and shoot delay control. It could be anything. Just help me out here.;-) I need 2 scripts basically one for my taget (main character) and a enemy. It doesn't need to be 2d it can be 3d, anything that would do such a thing would really help Thanks in advance~! PS: i have code for homing missile because i learned it from someone's youtube link. https://www.youtube.com/watch?v=s87zyCwHLgE
