With fields: <Code Omitted>you can use: <Code Omitted>to move; and: <Code Omitted>to deflect off other actors.

Show code of class with attempted codes pointed out. Then give very detailed explanation of what you are trying to do.

Insufficient amount of code provided. Please provide, at minimum, the entire method.

Please refer to my Scrolling Tutorial scenario.

I would go about it a totally different way. I would have mouse clicking on Pick objects toggle the existence of its reference being in a public static List in the Pick class. Then have the world act pick one when the list contains four elements (clearing the list afterwards). I am quite sure controlling the images would also be quite simple then (although I cannot see how the initial images are set). Other than the static List, the only other field required would be an int id to indicate which type item the Pick instance is. In all,

Add an act method to check and respond to possible keys:

It would probably help to first get the x and y offsets for the direction moving/facing: <Code Omitted>Now you can get the world background and compare the color at (getX()+dx*getImage().getWidth()/2, getY()+dy*getImage().getHeight()/2) to Color.BLACK. The color checking will need to be done for each case of moving direction.

You will need to make use of getScrollX and getScrollY. I guess one way to handle it is to negate the scrolled amount (un-scroll back to initial position), then add the player back in. Another is to subtract the scrolled amounts from the coordinates where you want the player.

I would presume that the code in Mouse Trap by Bourne would provide a decent example.

Are those amounts in the hundred thousands or world coordinate pairs? Also, please show attempted codes. It can go a long way in at least showing what you are trying to accomplish.

You want to ask about two distinct conditions such that if BOTH are satisfied, then execute some specific code. That is a logical AND operation (if condition (a) AND if condition (b) ...: <Code Omitted>The "&&" is the logical AND operator and "||" is the logical OR operator.

Makes sense. Thanks a lot!

Apparently, you need a String type argument: <Code Omitted>

Show main class codes with attempt.

ok, thanks for reply
