Question

I have recently begun coding a 3d computer game as part of my IB MYP personal project, Although I know a sufficient amount of Java I am having troubles getting my classes to work together. What I’m trying to do is create a class called block that defines a block and all it’s properties, then call the block class for a basic description of a block every time I create an individual block with unique properties. I’ve tried extends which works, but I’d have to create a new extending class for every unique block, and I’ve tried creating an object but it won’t work. All my searches turned up dry. Here’s my code:

package src;

public class Block {
    //Defines a Block

    double id; //Full = type, decimal = subtype
    String type; //Name/tooltip
    int sound; //Type of sound played on collision
    int light; //Ammount of light given off
    boolean breaks; //Wether the block is breakable
    boolean solid; //Wether the block has collision detection

}

How can I go about calling this object multiple times in a different class, each time with all the values slightly different?

Answer 1

You could have a constructor for a Block as follows:

public Block(double id, String type, int sound, int light, boolean breaks, boolean solid) {
    this.id = id;
    this.type = type;
    this.sound = sound;
    this.light = light;
    this.breaks = breaks;
    this.solid = solid;
}

With this, you can create as many different kinds of Blocks as you want.
