Just a wee note to thank you all for your help over the last few days - I've been scouring the forums for answers, starter sprites etc, while building a simple platform game as a summer project with my seven-year-old son.
He's been absolutely enthralled with the whole process of game-building, and as we've put him into the game, he really has taken ownership of it, and can't wait to show his friends when he gets back to school after the summer holidays.
There are a couple of wee bugs still to be ironed out, and one that I couldn't find an answer for is how to stop the player from reacting as 'falling' when standing on a solid platform with a vertical sine movement. Any hints would be much appreciated.
If you want to have a look at what we've built so far, I've published it to my own webspace at:
Many thanks again,
Happy dad with happy son!
