Here Is My Script
Anyone Know Why This Is Happen?
And How To Fix This?
As @Trigary said, always post your code int text form (the 101010 button is here for that).
About the question, as the debug console is alerting, in line 11:
if (transform.position.x < -15)
Should be
if (transform.position.x < -15)
You probably just copy-pasted that code from somewhere and didn’t even checked what is happening. The “& lt;” (without space) is the “<” symbol.
