if you give us more details about that "bunch of code", perhaps we could come up with something.

I guess that was directed at me? I'll just post the code, if you're interested. I'm sure this can be cleaned up and condensed, but at least it seems to work:

Code: ags

#define TOOLTIPWIDTH 50

bool _oldhighlight = false;
int _olddir = 0; // for exit pointers in various directions. Numbered 1-4 in the order up, right, down, left; 0 is regular pointer
bool _clickable = true;

String[] Split(this String*, String divider)
{
  String heads[] = new String[this.Length];
  int i;

  String tail = this;
  int nextDivider = this.IndexOf(divider);
  while(nextDivider != -1)
  {
    heads[i] = tail.Substring(0, nextDivider);
    tail = tail.Substring(nextDivider+divider.Length, tail.Length - nextDivider-divider.Length);
    nextDivider = tail.IndexOf(divider);
    i++;
  }
  if(tail.Length>0)
    heads[i] = tail;
  
  return heads;
}

void DimToolTip(String text)
{
  int width = GetTextWidth(text, eFontMiniFontOutline);
  int height = GetTextHeight(text, eFontMiniFontOutline, TOOLTIPWIDTH+1);
  int lines = height / GetTextHeight(text, eFontMiniFontOutline, GetTextWidth(text, eFontMiniFontOutline)+1);
  if(width > TOOLTIPWIDTH)
  {
    // Set the width to the minimum width that doesn't wrap over more lines than TOOLTIPWIDTH does
    width = TOOLTIPWIDTH;
    while(GetTextHeight(text, eFontMiniFontOutline, width) == height)
      width--;
    width++;
    
    // If any individual words are longer, set the width to that
    String tooltipwords[] = text.Split(" ");
    int i = 0;
    while(tooltipwords[i] != null)
    {
      int wordwidth = GetTextWidth(tooltipwords[i], eFontMiniFontOutline);
      if(width < wordwidth)
