Hej guys,

i started to write an AI on my own.
I simply started with a Car Depot building. But my AI doesn't build it.
Here is the Code.

 function TestAI::BuildSomething()
 {
   local firstTile = AIMap.GetTileIndex(2,2);
   local secondTile = AIMap.GetTileIndex(2,3);
   
   AIRoad.BuildRoadDepot(firstTile, secondTile);   
 }

I wonder why this won't work?! The terrain is flat and buildable. If I change the depot build command to the HQ build command, the AI will build its home. But neither depot nor road.


Thanks for help.

When anything related to building on the map, buying vehicles, changes orders etc. doesn't work try to find out why first. The easiest way you can do that is by printing the error message to the AI debug log. You can do that like this:

AILog.Error(AIError.GetLastErrorString());

Before building anything related to roads you must first call AIRoad::SetCurrentRoadType

Thanks for the clue!
The road type was missing.

Also IIRC you have to call AIController.Sleep(1); before doing the first action (DoCommand) as the first tick doesn't allow any actions/DoCommands.

Hej,
I've got a new Problem
These Enumerators are really confusing.

aSlope = AITile.GetSlope(aTile);

(Enumerators of Slops)
So far. So good. But what is now inside "aSlope"? There is a number. But I don't know what to do with it. When I've got a SLOPE_NW on my screen, it returns number 9?!

It's actually a bitmask.

SLOPE_NW = SLOPE_N | SLOPE_W;

Thanks for your fast reply. It helped me a lot!

Another question: Why are these two lines the same:
(both are initiated with local tileList = AITileList(); )

tileList.AddRectangle(start, end);

tileList.AddRectangle(end, start);

Both lists start with the end tile?!?!

If you want to sort the list you have to use the AIList.Sort() function. By default lists are sorted ascending by item.
