The name 'Message' does not denote a valid type ('not found').

When I try to create new message it shows this error:
“The name ‘Message’ does not denote a valid type (‘not found’).”

Help please.

Code:

class MessagePushAbility extends Message{
 
 var forceApllied:int;
 
 function MessagePushAbility(forceApllied:int){
 	this.forceApllied = forceApllied;
 	
 	super("push");
 }

}

There is no class called Message in the assembly. That’s why. Did you forget to install a plugin or something ?

What are you trying to achieve?
