It compiled and it is still wrong

My tile map renders sideways or mirrored

This page is part of Intro to Java with Greenfoot. It assumes you have reached lesson 6.2. Opening it is not counted against you and is not tracked as progress.

What it actually means

The row and column indexes are swapped somewhere, so the grid renders transposed.

The usual causes

Ranked by how often each one turns out to be the answer. Work down the list.

1. addObject is being called with row and col the wrong way round. The world wants x first, and x is the COLUMN.
2. The array is being read as map[col][row] instead of map[row][col].
3. The world is sized with rows as the width instead of columns.
