I have a problem with a Platform Game I'm making, when I press the an Arrow Key quickly after pressing another, (for example, right then left). The character freezes for a moment, and then starts moving as it should. I tried using a method by senocular but it ended up making things more complicated even though it gave me fluid movement. Here's the original code. Could a Senior Member Help me out?!
