Yet another segfault (a.k.a. Darkhog is a total noob)

[Darkhog]

No, function that is used is TGameObject.isColliding(GO:TGameObject). But thanks for suggestion, will try to check that.

[Darkhog]

Nope, checked if it is in range and still segfaults.

Are you sure CurrentSprite is a valid index?

You should not do this, , but try this, it will avoid anything wrong :

function TGameObject.isColliding(Sprite: TSprite): Boolean;
begin
  Result:=false; //setting result, just in case

  if (not Assigned(self)) or (not Assigned(Sprite)) then Exit;

  case ObjectMode of
    omAnim:   begin
                if (CurrentAnim>0) and (CurrentAnim<=Animations.Items.Count-1) then
                if Assigned(Animations.Items[CurrentAnim]) then //safety check so we won't get segfault
                  //setting result
                  Result:=Animations.Items[CurrentAnim].IsColliding(Sprite);
                end;
    omSprite: begin
                if (CurrentSprite>0) and (CurrentSprite<=Animations.Items.Count-1) then
                if Sprites.Items[CurrentSprite]<>nil then //safety check so we won't get segfault
                  //setting result
                  Result:=Sprites.Items[CurrentSprite].IsColliding(Sprite);
              end;
  end;
end;

I'm telling you this is not the right function, you're looking at! It

is TGameObject.isColliding(GO:TGameObject).

But I've used this code and it still crashes.

Had another quick look on the github. Are you calling right constructor for TAnimatedSprite?

constructor TGameObject.Create(mode: TObjectMode);
begin
  if mode=omAnim then Animations:=TAnimatedSpriteList.create;

the .Create is TObject.Create, it seems. The .Create without parameters is not written to either TAnimatedSprite or TSprite.

[Darkhog]

*TAnimatedSpriteList. And for a while I've thought you're right, but TAnimatedSpriteList.create is defined on line 186 of Sprites.pas.

Anyway, it then would crash as soon as I'd enter TDebugState since collision is checked constantly and thus Animations is accessed constantly and it only crashes if I make both game objects touch each other.

It may be something with TAnimatedSprite class though.

Any help? I can't pinpoint the issue at all!
