Hello, I am currently following along with a few Tutorial videos and I am currently working on a Tower Defense game that was included in the Project. I am not entirely sure what the conflict is I think it has something to do with the OnTriggerEnter2d function being called because I can manually have my Enemies go to the next CheckPoint by changing the Target int. below is Screenshots of the game and the code I used. I am pretty new to coding and I have searched for a fix but I am stumped. If you can help that would be great Thank you in advance!
EDIT The Issue I am having is my enemy reaches the first checkpoint but he does not move to the next checkpoint he only stays at the first checkpoint
