Copy AwesomeNameGuys checkForCollisions method but modify it to look below the object rather than beside it. Change the blockedOnRight to an onGround boolean. Now, wherever you increase the gravity (y speed), say if(!onGround) before. In the future, this may be an easier way to deal with this.

The code I gave you was intended for the actor class. Simply make a variable in the world class and use either of the codes I provided you with to modify that variable or check it.

how can C objects have the same rotation as B objects underneath, when Cs are created? i have multiple Bs with differend rotations

<Code Omitted>In the world <Code Omitted>In the key <Code Omitted>In the gate

That fixed it davmac. I was running 2.1.0. I upgraded to the current release of greenfoot and the warning is gone. I just don't like seeing the warning, especially since I teach an intro class. I don't want to worry about explaining it to them.

BTW your canMove() method will always return true: you are getting the actors current location (which must always be within the ranges of the world) and trying to return a false if they are outside the world (which will never be).

Ohh didn't knew i could use gimp, i will try it ;) thanks ;)

Looks good i will use it, i'm still new to greenfoot so i use all the help i can get ;)

Continuing above: my version was of a press, drag, and release type for any action. Even when flipping cards from the deck to the draw pile, press on the deck, move to the draw, and release (almost acts like your hand would; you have that extra moment to think if you REALLY want to continue flipping). My version is solely three cards at a time.

I fixed it!!! New revised code:

ignore this post it is fixed
