[AI] How do you make a bot with triggers?

[killer1390]

I just can't figure out how to make a bot with triggers! I need bots like the one in castle fight because I'm making a map like that, but I don't know how. So if anyone could help me do this I would be thankful.

There is no simple 1 trigger, 1 bot method. It requires many periodic events, random numbers, and conditions.

 

[killer1390]

Lol, i know that. i need an example as though there was one builder with one building!

 

[Kwah]

I'm not really understanding what you are asking for. Take a look at the Tutorials section.

 

[killer1390]

cool. the example i need is lets say there is just one race. it has one unit that builds, and there are two buildings. how do i make a bot build one of the buildings randomly?

 

[Kwah]

Event - <insert event here?

Actions
Set RandomReal (It's a real variable) = to Math(Random Number(0-1)
If:
RandomReal < .5 then order unit <builderunit> to build <buildinga>

Do the same if it is >.

 

[killer1390]

thank you i'll try it out!

He wants AI for a computer.

Actually I would like to see a semi-ai done with triggers myself as well. It would be a good learning experience.

 

[killer1390]

You're trigger did not work!

 

[Kwah]

Then you're doing it wrong.

I believe that in Castle fight they've done the AI in the AI section.

 

[Kwah]

I've never used the AI editor, so no comments.

 

[killer1390]

I don't believe the AI section has enough power to do that!

ai editor can't run in non-melee map

 

[terradont]

I believe it does, it has the power to make ai for DotA, so it would probably be able to handle a Castle-Fight type of map.

are you talking about the Dota -ai maps with heroes controlled by computers or just the creep spawns?

 

[CheatEnabled]

ai editor can run in non melee map btw. its designed to work best for melee style games

Slightly offtopic here, if I may, how do they do those? Massive triggers for each possibility or AI editor?

The heroes? Yeah i was asking the above person if he meant its done in the ai editor so was trying to find out too. I always assumed it would never be done in AI editor and only be done with vJass triggers.



Im programming an AI atm - a game that has houses to hide from "predators" i'm making the predators spread out and search each different house, and narrow their search if their suspicious of the area, and sometimes "assault" the house by blocking escape measures "such as a spell snare for blink" when a few players are in a house.

Different systems (vJass libraries) for different modes activated, such as "General Search" which finds out what order needs to be given (such as move to locations) and keeps reissuing the order.







Sometimes a good idea is an order que the can be found here: http://www.hiveworkshop.com/forums/f413/orderqueue-shift-triggers-84857/





As for dota hero AI my thought would be alot of different eventualities change the behaviour of the ai. A complex system that calculates decisions based on basic things like current unit health of hero, if a tower is nearby, what hero their facing. different eventuallities means a different decision e.g. to chase the hero or not

That's pretty much exactly correct. AI Editor is only used when you want to make a custom race for a melee map, though it can be used in non-melee. You basically just input the units, buildings, researches and things like that, and when the AI runs, it will be as though it were a normal melee game, but the Computer Player makes its decisions based on the things you put into its AI.

So basically what you would want to do is make many seperate triggers which tell the "AI" what to do in certain situations. Say they have a main structure to defend, and you want them to fend off attackers. You would just have the trigger run when the main structure is attacked, and order the AI to attack the intruder with whatever unit resources it controls. That's just an example, but you get the main idea.

ok, as i said i'm not very confident in the AI-editor. I guess the AI in DotA AI is triggeed(yes, the heroes)

This will make when player 1 have enough gold for a building when player 2 (enemy in the case) have the building producing gryphons player 1 to build one of the buildings that are set in the trigger. AI making is hard and i never deal with it but if u try few times u will learnk how to deal with it

• Build 1
  • Events
    • Player - Player 1 (Red)'s Current gold becomes Greater than 1000.00
  • Conditions
    • (Number of units in (Units owned by Player 2 (Blue) of type Gryphon Aviary)) Greater than or equal to 1
  • Actions
    • Set random = (Random integer number between 1 and 3)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • random Equal to 1
      • Then - Actions
        • Unit - Order Peasant 0000 <gen> to build a Workshop at (Center of (Playable map area))
      • Else - Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • random Equal to 2
      • Then - Actions
        • Unit - Order Peasant 0000 <gen> to build a Barracks at (Center of (Playable map area))
      • Else - Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • random Equal to 3
      • Then - Actions
        • Unit - Order Peasant 0000 <gen> to build a Gryphon Aviary at (Center of (Playable map area))
      • Else - Actions
