I am trying to fade in a dynamic image, but when I try this bit of code, it seems to go into an infinite loop.  
I’m confused, because it makes sence to me 😕  
It seems to always crash when I do the WHILE part (i’ve tried different while loops)

```auto

do {
  fadein()
  }
  while (this._alpha < 100) 

fadein = function() {
if(this._alpha < 100){
                this._alpha += 5;
        } 
	}

```

Any suggestions?  
Thank you!
