Hello. I am fairly new to Greenfoot so pardon my noob-ish knowledge.
Basically all I want is to make an array of objects. These objects will be side by side and will be used for my game's floor that I have already coded to prevent the user from falling through. Each object is a square and basically depending on the level, the pattern I would like the floor to be will be different.
For example if: = 1 block.
I would like it to form .
Instead of manually placing the coordinates of each object I would like an array that I can eventually configure to space it out.
This is roughly the same code I'm using to make my "array" which is providing me with Null Pointer Exception Errors.
Thank you.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)public class Screen extends World{ /** * Constructor for objects of class Screen. * */ public Screen() { // Create a new world with 600x400 cells with a cell size of 1x1 pixels. super(600, 400, 1); block[] blockArray = new block[5]; for (int i = 0; i< 5; i++) { addObject(blockArray[i],(287+(5*i)), 488); } }} |
