How would I be able to include preemptive strikes and surprise attacks. Currently I set up a system where when the enemy sees you he chases you (no random encounters). I would like to add the option if you sneak up on an enemy from behind and touch them you can gain first strike or preemptive strike, while if your running away and have your back turned and they catch you, they initiate a surprise attack.

There was a script by cozziekuns for this in VX, but I don't believe one has been designed in VXA. Forever's End (RM2K3) has a similar design, and since 2K3 uses events over scripting, you could either check with the game's developer or open the game up in the editor to see how it was done.

I could be mistaken but RM2K3 had the option in the events where as ace does not ... or it would appear so.

Which would explain why Forever's End was able to implement this. In VX a script was needed, and I'm sure it will be needed for VX-Ace as well, but I haven't heard of a script being made for Ace that would allow this. You can always request cozzie's script to be ported over for Ace in the request section or on RMRK.

Here's the script for VX:

Umm was the script request moved?? I cant seem to find it?
Thanks for the VX script, I cant believe its so hard to do on Ace!

There was no script request for VXA. This is for VX. If this is the script you need, and you want it implemented in VXA, you'll need to request it yourself.
