I have things to where the player is on one layer, and the level mc (the ground) is below it on its own layer; I call it the bg mc, and it scrolls with the arrow keys. All obstacles and items are in the bg mc. I am trying to get the player to ‘chase’ another npc around when they hittest it.

At first I used a simple walls code that I put on 4 line mcs to form a box around the object, and then put them in the object so the player basically pushes the mc around, appearing to have ‘chased’ it-

Example:

onClipEvent (enterFrame) {  
if(this.hitTest(\_root.player)){  
\_parent.\_x+=12;  
}}  
(this is for the left line, so the player pushes it to the right)

This works essentially, but makes the object mc huge, and sloppy looking when pushed. I also have to put multiple mcs of this throughout the level, so I can’t name the object (and don’t want to name it).

I tried this code for the object in a test scene with the just player, and the object on its own layer:

onClipEvent (enterFrame) {  
distance = 60;  
x = \_root.player.\_x;  
y = \_root.player.\_y;  
ex = this.\_x;  
ey = this.\_y;  
if (Math.sqrt((x-ex)_(x-ex)+(y-ey)_(y-ey))\<  
distance) {  
if (rx\<erx-30) {  
this.\_x += 12;  
}  
if (x\>ex+30) {  
this.\_x -= 12;  
}  
if (x\<ex-30) {  
this.\_x += 12;  
}  
if (y\>ey+30) {  
this.\_y -= 12;  
}  
if (y\<ey-30) {  
this.\_y += 12;  
}  
}  
}

It works splendidly, but when I put the object mc BACK into the level mc, it stops working entirely…

I think its because the coordinates between the object and player change because it has to go through the new, and large bg mc. I have no clue on how change the new code to accomodate the desired action through the bg. Could anyone please explain how to fix this?  
Thanks 😉
