Hi,
I'm back again with another question, sorry. When I try to compile my EnemyTank class, it gives the following error: "Constructor EnemyTank in class EnemyTank cannot be applied to given types
required: boolean
found: no arguments
reason: actual and formal argument lists differ in length
Code for EnemyTank class:
Error concerning lines 28-33.
