Question

I have many different Units on a map and I want to discover which one has been clicked by the mouse. I want to do something like this:

private function setupUnit(gridx:uint, gridy:uint):void {
    unit = new Unit(gridx, gridy);
    unit.addEventListener(MouseEvent.CLICK, onUnitClick);
}

private function onUnitClick(e:MouseEvent):void {
    active_unit:Unit = e.target;
}

And later use active_unit.method(). But this throws the error “Implicit coercion of a value with static type Object to a possibly unrelated type Unit”

I’m sure there’s a super simple way to do this =P. Any recommendations?

Answer 1

Just cast the value to the right type or use the as keyword.
The cast will raise a runtime exception if it’s not the right type, and the as keyword will return null:

var active_unit:Unit=Unit(e.target);
// or
var active_unit:Unit=e.target as Unit;
