2D tileset generator

This is great idea and it is already on To-Do list for my program. But as I sad before you probably don't wanna wait for me as my program probably won't be finished soon.

Yep, i won't wait You can track progress here if want:

It is much more complicated structure than one could imagine at first glance. I'm still working out some details, but i believe that after (propably) finishing "Tile styles"-dialog today, it cleared up alot. Also found and reported a Lazarus bug in the process... everybody benefits, lol.

Also experimented temporarily with class default properties with record array as type, it failed. I won't need it now, but is it even possible to get such working? Something like (simplified):

type
  TTileStyle = record
    name: string;
    ...
  end;

  TTileStyles = class
  private
    FStyle: array of TTileStyle;
    function GetStyle(index: integer): TTileStyle;
    procedure SetStyle(index: integer; value: TTileStyle);
  public
    property style[index: integer]: TTileStyle read GetStyle write SetStyle; default;
  end;
...
function TTileStyles.GetStyle(index: integer): TTileStyle;
begin
  result:=FStyle[index];
end;

procedure TTileStyles.SetStyle(index: integer; value: TTileStyle);
begin
  FStyle[index]:=value;
end;

I tried above'ish code, it compiles and all. But when i changed value from some record, it didn't change. Reading propably worked. I have a guess that it should've been pointer to record, so writing would work.
Also another problem with "name" clashing with propably some internal "name" related to default parameter.

A quick glympse at your code shows that you are using dynamical array but have no mechanizm for modifying array size. You can't save any data into array if it doesn't have any elemets as newly created dynamica arrays have.

I am using SetLength(). See function TTileStyles.Add() or Delete():

You don't even need to have variable to track array size. Length() and High() ( = Length()-1 ) can be used to retrieve that information.

Oh, as you saw in other thread, i took an entirely different approach for tile blending. Making of this tool was cancelled for few other reasons aswell... to put it with simple words: it was complicated, and no clear purpose.
