GuiCtrl Fader

[xXziroXx]

Uses alpha in order to fade it in and out depending on if you're hovering your mouse over the GuiCtrl or not.

Complete script, with a GuiWindowCtrl included as example on usage.

PHP Code:

//#CLIENTSIDE
function onCreated()
{
  new GuiWindowCtrl("ExampleGui") {
    alpha = this.baseAlpha = .3;
    
    thiso.catchevent(this, "onMouseEnter", "onMouseEnter");
    thiso.catchevent(this, "onMouseLeave", "onMouseLeave");
  }
}

function onMouseEnter(obj) scheduleevent(.05, "FadeGUI", "setValue", obj, 1);
function onMouseLeave(obj) scheduleevent(.05, "FadeGUI", "setValue", obj, obj.baseAlpha);

function onFadeGUI(mode, obj, value)
{
  // mode: 'setValue' or 'changeAlpha'
  // obj: GuiCtrl or name of GuiCtrl
  // value: Alpha to reach

  temp.modifier = .1; // How much should the alpha change every 0.05 seconds?
  
  // Let's lets make sure that 'obj' really is a GuiCtrl, shall we?
  if (obj.name == "obj") {
    // If the GuiCtrl exists, we got it!
    with ((@obj)) obj = this;
    
    // Can't change alpha on a TGraalVar!
    if (obj.objecttype() == "TGraalVar") return;
  }
  
  // Tadaa!
  if (mode == "setValue") {
    cancelEvents("changeAlpha");
    obj.targetAlpha = value;
    scheduleevent(.05, "FadeGUI", "changeAlpha", obj);
  } else if (mode == "changeAlpha") {
    if (obj.alpha != obj.targetAlpha) {
      if (obj.alpha > obj.targetAlpha) obj.alpha -= temp.modifier;
      else if (obj.alpha < obj.targetAlpha) obj.alpha += temp.modifier;
      scheduleevent(.05, "FadeGUI", "changeAlpha", obj);
    } else cancelEvents("changeAlpha");
  }
}
