Dispatch Enemies around a Target

Hi everyone,

I request your help in order to know if I am in the good direction or if you know a better way to achieve what I am presenting here.

My goal is to have different targets that several sprites could dispatch around and focus to attack in the future.

I did this capx in order to show you my way of thinking but even if it is working, I'm really not sure of the efficiency <img src="smileys/smiley5.gif" border="0" align="middle" />

My FPS drops really badly with the bullet behavior. Each time a new "character" is created and moves, my FPS drops at 17 FPS on PC (chrome) :( and I have nothing.. That's scared me a lot for the future, so, this is why I request your help.

FPS is back to 60 if there is no more sprites moving.

Am I on the correct track?

Is there a better way to achieve what I did?

Thanks for any help.

here is the capx

I tested this capx and see no real slowdown. I'd like to know what kind of PC you have. OS, GFXcard etc etc .. Especially if it's laptop/Nvidia, since those can be really slow sometimes.

On my desktop PC (6core athlon, W7/64bit, Radeon 78xx) I see no slowdown. Ffox has some frame rate jitter, but chrome is real close to 60fps..

Hi Joannak and thanks for your feedback.

My PC is becoming old, here is the stats:

Intel Dual Core, 2.33 GHz

Ram 2 Go

NVIDIA Geforce GTX 285

My goal is to develop for mobile (tablet)

Thanks
