The Main feature of the targeting system is being able to change from First, Last, Strong, Weak enemy types. This gives the player way more opportunity for different strategies. There is also custom shading at work with outlining the tower on mouse hover and when clicked on. The system uses triggers to detect enemies according to the attack radius and adds them to a list that a tower can filter through depending on the targeting type.
I also plan on implementing these magic attacks that I created. I sourced the animations themselves from the Asset store but the fireball VFX is my work.
