I just played your standalone test map. I was able to get to the exit without losing a life the second time I tried to play it. My first time through I lost one life.
-Bugs I noticed
1. It seems the first 2-3 bullets the enemy shoot do no damage at all. This includes running straight into an enemy and getting them to fire at point blank range. Once an enemy has shot around 2 or 3 bullets their shots begin to do damage. Its easy to recreate this bug - just play the standalone and at the start run a big circle around the group of enemies and they will all start to shoot and for the first few seconds you will take no damage.
2. If you get an enemy into melee range and they do the kick animation you can get them to repeat it by just walking at them again. So if an enemy charges me and I am low on life or reloading or w/e I can just avoid them damaging me by walking back into their melee range(causing them to kick me again) until I finish reloading and waste them.
3. Enemies will sometimes start spinning around moving in a small circle. Mostly happens when they charge the player.
4. Enemies "know" where I am when they shouldn't. And I think this one is pretty big because it really breaks immersion. For example on the standalone map I was positioned behind the back wall (the one that is directly behind the player when you spawn in). I had three soldiers on the right side of the wall behind sandbags. I decided to flank them so I crouched walked left and walked all the way around down the left wall. To my surprise when I stood up to shoot them in the back of the head they were already looking at me and killed me in a nano second.
My general first impressions was that the AI was much more "fun" to play against. It seems like a good starting foundation. But for me it's the small details that always get me.
Sometimes, the way they would pop up and go back down behind cover was strange. It looked like what I can only describe as a game of whack-a-mole.
It's hard to tell if the AI is looking at you or not since they always have their guns help up in a "ready" position.
Their bodies and weapons don't respond if you are crouching or on top of the sand bags, they always have the pistol pointed straight ahead.
Rarely would they choose a good time to charge at me.
They never flanked my position only got to cover and then would charge or stay or roll into the wall.
Almost impossible to tell if they are taking damage unless you are point blank. Maybe more blood or a more prominent blood effect is needed?
Can't tell if an enemy has been injured. Whether they have 100% life or 2% life they act the same.
That is all I can think of for now. But overall it feels like a huge improvement over the old AI. Fantastic Work.
