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:

What line are you actually getting the error on? It sound like you are, somewhere, trying to create a new EnemyTank without passing the required boolean parameter, but I can't see that in the code you've posted. (Seeing as your constructor requires a boolean parameter, you must always pass a boolean when you create a new EnemyTank instance, eg "new EnemyTank(true)")

The error hasn't happened now, but thats because I've decided to omit the code temporarily for the Enemytank class. The error occurs when I compile the TerrainWorld constructor

Error in lines 125 and down, and sorry for the extremely messy coding.

Either add another constructor to your EnemyTank class, as follows:
?
1
2
3
4
public EnemyTank()
{
    this(false};
}
Or, create your EnemyTank objects with 'new EnemyTank(false)' (unless you want a large one -- then use 'true')

I need help with something similar, in my pokemon game I want to have an enemy appear every few steps I take, but the constructor for enemy required an int and a class from playerheroes.

You should start a new discussion thread on your issue -- not revive one that is over two years old. Also, you need to supply the codes you are currently using (the class of the enemy and the class of the playerheroes).
You need to login to post a reply.
