Multi touch? Turn label upside down?

[Barry Evans]

Hi folks,

After building a simple 'Pong' app as part of my uni course, i decided to try adding a few features to improve it a little and so it stands out when compared to my classmates'. I wanted to make it a two player game (basically air hockey) with players holding opposite ends of the device. The first issue with this is that the player on the opposite end of the screen can only read the scores etc upside down. I'd like to set a label upside down at the other end that mimics the one player 1 would read. The other (and far more pressing issue) is that the device will only allow for one sprite (paddle) to be moved at any given time. I have no idea at this stage how to progress or if either of these things can be done. As always I would be grateful for any advice.

Many thanks

Barry

That multitouch idea is very useful. I will go update myself on that now. The upside down text one wont fit for me as i need something that can update in real-time, ie the player's score, but I feel from reading the posts around those you linked that its unachievable. I will rethink this and try a new approach.

Thanks for your help.

concerning upside down text, what about using a canvas ant the DrawTextAtAngle block?

You could add a slider at each player's end to control his paddle location.

Some really useful suggestions there folks. Thank you all very much. Trying a few of these ideas now and definitely feeling more confident I can get this app to where I want it to be. Appreciate the advice as always.
