I’m pretty new to programming and actionscript so making a game like this is probably a bit much for me, but it’s still cool to try.

Ken: I’d imagine you’d want to use a similar method that the turrents use to work out when an enemy is close enough to a turrent and then make the enemy move out of the way… you’d need some places where you can’t build though.

Martenp: You could construct a menu when the user clicks on a black spot which then lets you chose which type of turrent you build or have a menu at the bottom which changes a variable to what turrent you want and then add some if and else if statements to decide which turrent is created. If you understood all the code in this tutorial it shouldn’t be too hard. To upgrade make an onRelease function for existing turrents which could add to the variable controlling the damage the turrent gives, or you could construct a new turrent over the old one.
