[NOTE] Using CancelSelectTextDraw in OnPlayerClickTextDraw (without bugging up) - Hiddos - 24.03.2012

I've got no clue why, but CancelSelectTextDraw calls OnPlayerClickTextDraw (Seriously, what useful information would it pass?).

Code like this:

pawn Код:

public OnPlayerClickTextDraw(playerid, Text:clickedid)
{
  /*
    -- other code --
  */
  CancelSelectTextDraw(playerid);
}

CancelSelectTextdraw calls OnPlayerClickTextDraw, so using the function in OnPlayerClickTextDraw results in an endless loop.

I did some research and found that CancelSelectTextDraw calls OnPlayerClickTextDraw with a textdraw ID of 65535 - INVALID_TEXT_DRAW. That said: If you want to use CancelSelectTextDraw in OnPlayerClickTextDraw without creating an eternal loop, you'll need to adjust your code to something like this:

pawn Код:

public OnPlayerClickTextDraw(playerid, Text:clickedid)
{
  if(_:clickedid != INVALID_TEXT_DRAW)
  {
    /*
      -- other code --
    */
    CancelSelectTextDraw(playerid);
  }
}

I guess they'll fix this in a later RC, but for whomever is already experiencing problems this could be a workaround.

Edit: Small fix
Edit: Tweaked 65535 to INVALID_TEXT_DRAW - thanks to Stepashka

Use special define for check invalid TextDraw ID

pawn Код:

if (clickedid != Text:INVALID_TEXT_DRAW)

And never cleared value type!

I've looked around the forums a bit and noticed I wasn't the only one having this issue. You would've found out as well if you'd use it I guess
