1. i have my enemies just spawning in same spot forever  
id like to set up a global variable that will increase when i press right  
and then when that variable reaches certain numbers… like 300 and 600  
i want an enemy to be attached
2. if u test this youll see enemies coming from one side  
how would i make them come from both sides  
[HERE IS A DEMO](http://spamtheweb.com/ul/upload/050608/8449_game.php?lightbox)  
if you know how to solve either of these please by all means assist

all im doing is attachin a movie using  
a copied code…  
_dont get me wrong i can completely remake this whole code its pretty much the only enemy ai code i ever used and ive tweaked it from bottom to top plenty of times_  
_what it does is attaches an enemy and the enemy follows the AIzombie function  
which tells it to walk or die and if i hit any of the monstersinscene they die and are removed from the stage  
which will then make another respawn_  
this isnt the code that i will use if someone can help me with the global variable thing im asking for  
i want it so that when my character is moving right the global variable called MainX is increasing by increments of 10  
and once it reaches 200 i want to have a movie attached at at the coordinates \_x:600, \_y:305 and i want the movieclip to follow the same function that is listed below but ill take out the part that makes it spawn again
