Guide for Enemy A.I?!

mmmodel

Hello guys, somebody know where i can found some guides for enemy a.i?!
I tried to found something about but without success.
I know the basics like movement 'go' and 'back' and the follow rule(follow the player) but i really need to found how i make the point of collision to decrease the health of the player (like some punch in the face of the player or sword attack )
i have some idea how to start but i need some tips or some nice guide to study.

Sorry about the question but i really don't no what to do

Thanks )

Someone else may be able to point you toward some resources but generally AI is just something you have to figure out how to do depending on what you want the enemies to do. If you want the player's health to decrease when the enemy collides with the player, that's not really AI... it's just a simple When actor collides with [enemy actor] --> Change Attribute self.health to self.health-1 rule.

What exactly are you wanting to have your enemy do?

Hello, how are you? @tatiang
so, i want when the enemy punch ( he has the animation sprite) the player health will decrease, i did the basic collision for one monster but i have the boss in the end of the scene and he has this attack but i need that he decrease the health of the player when the punch collides in the player.

Thanks for the answer

And i tried to make one rule for when the enemy see the player he runs after him, but seems not working, you can tell me what i really need to do?
sorry for ask another thing

Hey @mmmodel you can make a Boolean Global Attribute called Boss Hit and in the animation rule for your bosses punch you can add a timer set to the time in the frame when the bosses fist is extended and add a rule that states at that time the if boss collides with actor player to change that rule to true. And then in the player set a rule that states if Game.BossHit is True change player health to -whatever value.

@ironDan amazing solution!! i will try this, but i think that will work great for the boss, thanks for the help

ironDan

No problem, just remember to set a rule in your boss actor that say when not colliding with the actor to change Game.BossHit to False or he will only register his first punch.

okay, thanks for the tip

Here is a video I did a long time ago. It should get you pointed in the right direction. When I have some time which could be a few weeks, I may do some stuff on AI as I've built several, especially the AI I built for Puck It.

Hello @FryingBaconStudios i will watch the video now, thanks for the help

These videos are great to bring ideas on the backend of how AI is done. You could take these ideas and implement them into GS. Obviously it's not a direct how-to, more to just get the creative juices flowing.

@JGary321 lovely tip, thanks so much!

I have a little problem, i made some 'constrain att' to make my self position and i created some int for my player for the position y and x so i created for my enemy one 'move to' rule to follow the player in the scene but the enemy just face the player and when i run away he don't chase me like i wanted, what i'm doing wrong? maybe i need some bool to reset the position when he face's me?! or something like that?! thanks and sorry about the question =T

mmmodel

But if the enemy don't touch the player he continues to follows, but when he collides the problem happens =P

mmmodel

and i tried to make the rule
that says att self.distance < some number..
move to
position x, position y
and worked great, i think hahahaha
but i still don't know what to do when the enemy touches the player and he is stopping.

Try putting the 'move to' in a timer and set it for .001. That way it will keep following every after it reaches you.
