   Enemy spawning in 2D shooters (powered by Unreal 2004)
  Hi all, hopefully I can get some help on a little hurdle my team has come across.First of all we''re developing a 2D scrolling shooter with 3D visuals. We''re going to use Unreal 2004 for the engine.Our problem is that we''re unsure of how to do the enemy spawning. In typical scrolling shooters how are enemies spawned?Do they appear from a spawn point with this spawning triggered when the screen scrolls at a certain point or are the enemies already on-screen yet only ''move'' when the scrolling reaches them?We''re really unsure how to do this, so any help is much appreciated.Thanks,Neil
