While trying to test on iPhone 13 I am getting a error for a code I don’t have
Are you using updated companion? What is the version? Have you tried with legacy connection, check box marked in the companion??
I don't know iOS error codes.
However, I know Sprite events, and these are wrong:

In the When user Collided With event, you should be testing
if other = enemy then
call fight_activate
You never set the other value.
Likewise in the When enemy_activate CollidedWith event, it should be
if other = user then
call fight_activate
