transition vs physics for moving objects around

Hi all,

I decided to not use physics for my tower defense games thinking that it will be less processing heavy and I can cover more devices (especially the low end ones). So for me to move objects around I choose to use transitions instead, for things such as:

  1. enemies, given 3 waypoints and they will move to those points using transition
  2. bullets from the tower moving towards the enemy.

After reading this thread I am starting to doubt my decision: http://developer.anscamobile.com/forum/2010/04/23/discussion-about-how-speed-your-game

transition is apparently slow? and not intended to have high performance, and it is possible for a tower defense games to have a lot of bullets on screen moving using transition, would this be bad? Should I just use physics? [import]uid: 11334 topic_id: 4651 reply_id: 304651[/import]
