Problem WITH!!!!! Ai

[Lord Aro]

the error message provides you with valuable debugging information:

The first red line gives you all the info you can get: the error occurred in RoadPathFind.nut, on line 5, character 9

[Arie-]

As it seems you are a really inexperienced programmer, three things you should know (there are more but these are really important for you at the moment):
1- Think about your code: what do I want the code to do, how can I achieve this (in a general way), then think about programming language specific approaches.
2- Write code: get familiar with a language and it's properties.
3- Debug: learn what debugging is and how to approach errors and their causes.

These three are very general but apply to all languages. An example for you concerning squirrel, you want to construct a route between two cities.
1) Think about your code. You need to find cities to construct routes in between. You need to construct the route (roads, depots, stations, cars). Now we know this, think about the cities in more detail, how do you find cities (based on which properties do you want te select cities etc.). If that problem is tackeled, you need to know how to construct a route, build depots and stations, where do you want to place those, what is your approach when connecting the two towns with roads etc.
2) Write code. You now know your general approach to the construction of the route, now you need to put your thoughts in squirrel language. An example is:

Code: Select all

- get a list of towns
- sort the list of towns descending
- get the first two towns
- construct a road between the two towns
- build a station in both towns
- build a depot in both towns
- build trucks
- give orders to the trucks
- start the trucks

3) Debug. Obviously you are going to get errors, now you need to know how to find and fix those errors. Find line numbers, find error descriptions and try to understand them.

But i can't find a error becouse non pop ups on me

[Lord Aro]

in that case there isn't an error


to see ai debug output go to far right button on menu bar and select ai debug

[Ar4er]

i know that
i get only this

[Lord Aro]

Ok, now add:

Code: Select all

AILog.Info("*function-name*");

to the beginning of each function. Then post the debug screen

But i can't find a error becouse non pop ups on me

Have you read bullet three: "You are going to get errors.". Ergo: know what your code should do, and if something doesn't go as expected, learn how to find what goes wrong. An error is not only an error when you get notified. You really have to be more specific and have to put in more effort yourself because people are going to ignore you if you don't google yourself.

Nothing's there

Can you download this file and look for your self

But why my Ai isn't building anything i quess problem is in here

Code: Select all

function AcelaExpress::Start()
 {
   AILog.Info("AcelaExpress Started.");
   SetCompanyName();
  
   //Keep running. If Start() exits, the AI dies.
   while (true) <----------- here is the problem. while (true) stay here so he will always stay u forgot the brackets
{ <------ opening bracket
   			this.Sleep(1);
			Debugs.Warning("Main loop started"); <-------- this line will also give an error
			Manager.ManageLoan();
//			Debugs.Debug("manageOnly = " + RoadPathFind.manageOnly);
			if(RoadPathFind.manageOnly == false)
			{
				local vehList = AIVehicleList();
				vehList.Valuate(AIVehicle.GetVehicleType);
				vehList.KeepValue(AIVehicle.VT_ROAD);
				local numOfVehs = vehList.Count();
				if(AIGameSettings.GetValue("vehicle.max_roadveh") <=  numOfVehs)
				{
					Debugs.Info("Max amount of road vehicles reached");
					RoadPathFind.manageOnly = true;
				}
				else
				{
					RoadPathFind.Main();
				}
			}
			else
			{
				Debugs.Info("Sleeping because there is nothing to build");
				this.Sleep(25);
			}
		}
       } <------ close bracket
 
 function AcelaExpress::Stop()

But why my Ai isn't building anything i quess problem is in here

Code: Select all

function AcelaExpress::Start()

 function AcelaExpress::Stop()

error

[Radicalimero]

those arrows <------
where to point out the problem the correct code should be

Code: Select all

 function AcelaExpress::Start()
 {
   AILog.Info("AcelaExpress Started.");
   SetCompanyName();
  
   //Keep running. If Start() exits, the AI dies.
   while (true)
   {
   			this.Sleep(1);
			AILog.Warning("Main loop started");
			Manager.ManageLoan();
//			Debugs.Debug("manageOnly = " + RoadPathFind.manageOnly);
			if(RoadPathFind.manageOnly == false)
			{
				local vehList = AIVehicleList();
				vehList.Valuate(AIVehicle.GetVehicleType);
				vehList.KeepValue(AIVehicle.VT_ROAD);
				local numOfVehs = vehList.Count();
				if(AIGameSettings.GetValue("vehicle.max_roadveh") <=  numOfVehs)
				{
					AILog.Info("Max amount of road vehicles reached");
					RoadPathFind.manageOnly = true;
				}
				else
				{
					RoadPathFind.Main();
				}
			}
			else
			{
				AILog.Info("Sleeping because there is nothing to build");
				this.Sleep(25);
			}
		}
	}

Code: Select all

         Debugs.Warning("Main loop started"); <-------- this line will also give an error

this is because AroAI uses a custom Debug system. you will have to change it before anything will work

also, you can't expect us you write your code for you. Most of us have our own AIs to write. you MUST learn what the error messages mean and how to fix them.

[Ar4er]

it seems to work becouse that i see some working on ai debug
now i can finaly do something by my own


As for the error i think i fix those lines where is error by AILog.Info i quess that would work

[Ar4er]

i done it i done thank you Lord Aro, Radicalimero, And Zuu
Thank you all i am so sorry if i was big pain thank you guys best forum ever now i am going to try add function so he makes 3 town route

[Lord Aro]

well done!

don't forget to credit me!
it took me months to get that code right...

[Ar4er]

don't worry i am not selfwish
and i would buy you a cake if you lived next to me

[Ar4er]

One more question how to make my ai so he do random events like one time he is building buses but another time trucks

[Lord Aro]

I would do something similar to the company name picker. You would have to write a lot of code so the AI can support trucks though.

[Ar4er]

i was think about that too but i didn't find this way of coding in any AI

[Brumi]

There is a bunch of random functions in AIBase: http://noai.openttd.org/docs/1.0.3/classAIBase.html
For example if you want to use trucks in 64% of the cases, do this:

Code: Select all

if (AIBase.Chance(64, 100)) {
	// build trucks
	...
} else {
	// build buses
	...
}

AIBase::RandItem() is useful if you want to arrange items in a list in a random order. I use this in the industry/town selection alghorithm in SimpleAI. (see cBuilder::FindService() in builder.nut)
Example of this:

Code: Select all

local townlist = AITownList();
townlist.Valuate(AIBase.RandItem); // after valuating the items are arranged in a random order

local town = townlist.Begin(); // pick a random town

SimpleAI uses a lot of random functions here and there, the only problem is that my code is not very well commented, so it is not the easiest to understand
