moveCollide question!

(Nate ) #1

Okay guys so I decided to go a different route for setting up my platformer! I found a tutorial dated from 2011, however it allowed me to set up my basics for my game. I didn’t realize that I was working with an older version of FlashPunk until I was done setting everything up.

After switching everything seems to be in working order except two function in my Player.as class.

The error I am getting is this:

"col: 28 Error: Incompatible override."

Basically inside of the Player.as update function I have these two functions:

override public function moveCollideX(e:Entity):void
{
	xSpeed = 0;
}
override public function moveCollideY(e:Entity):void
{
	ySpeed = 0;
}

Let me know what you guys think! Thank you!

The functions need to return Boolean, like so:

override public function moveCollideX(e:Entity): Boolean
    {
        xSpeed = 0;
        return true;
    }
    override public function moveCollideY(e:Entity): Boolean
    {
        ySpeed = 0;
        return true;
    }

To override a function it needs to have the same arguments, accessibility and return type as the function it wants to override. These functions are defined as so in Entity.as:

     /**
	 * When you collide with an Entity on the x-axis with moveTo() or moveBy().
	 * @param	e		The Entity you collided with.
	 */
	public function moveCollideX(e:Entity):Boolean
	{
		return true;
	}

	/**
	 * When you collide with an Entity on the y-axis with moveTo() or moveBy().
	 * @param	e		The Entity you collided with.
	 */
	public function moveCollideY(e:Entity):Boolean
	{
		return true;
	}

Thus your override functions must be public, have one argument that is of the Entity type and must return Boolean in order to be compatible.

Okay just changed to have it return the boolean value and it worked like a charm!

thank you so much! :smiley:
