Hi!  
This should be very simple: I want to fade-in a Movieclip (called MC1) using Actionscript.  
I normally use this (and it works just fine):

[AS]  
this.MC1.\_alpha = 0;  
this.MC1.onEnterFrame = function()  
{  
if (MC1.\_alpha \<100) {  
trace(MC1.\_alpha);  
MC1.\_alpha +=5;  
}  
};  
[/AS]

However, this time I need to do it without using a function, so I’ve tried the following:  
[AS]  
this.MC1.\_alpha = 0;  
while (MC1.\_alpha \<100) {  
trace(MC1.\_alpha);  
MC1.\_alpha +=5;  
}  
[/AS]  
Well, even though I can see the alpha values decreasing step by step (throughout the “trace” instruction), the fact is that the MC does not fade-in at all, it’s just starts at a 100% alpha value.  
How comes this illogical behaviour? The instruction “trace” shows what it should do, but Flash does not fade it in.  
How can I do then what I want?

…this AScript is killing me…!

Thanks for reading,
