My player cannot move diagonally

This page is part of Intro to Java with Greenfoot. It assumes you have reached lesson 2.7. Opening it is not counted against you and is not tracked as progress.

What it actually means

The key checks are in an else if chain, which stops at the first key it finds.

The usual causes

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

  1. Using else if between the direction checks instead of separate if statements.
  2. Returning out of act() after the first key match.

How to fix it

Change every `else if` between your key checks to a plain `if`. Separate ifs are each checked, so holding two keys moves the player both ways in the same frame.
