I added this check to the On Trigger Enter function of my projectiles… basically if you line 3 enemies up and ranged attack the 3rd, your projectiles will go through the first two… I put in a check that sees if it hits the first one that if it has the same tag, fighter().CanAttack is true, and the Health component is not the one we were aiming for, then make this thing we just hit our new target and let the action scheduler know this is our new action (other wise your hero will auto fire through all the enemies until the original one you clicked is dead)
EDIT - I also added a check to make sure that we aren’t switching targets on a target behind a target we missed because they are moving… this adds a few more things in the vars setup and in update… basically it get the initial distance to the aim at location, and in update tracks the distance of travel from the projectile to the instigator… if the distance of travel is >= initial distance, the projectile has passed the target and the fails the new if statement… if you want that functionality I included my entire projectile script here…
new script here

the first if statement is the added part to correct his
