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

The << current state >> would be the isTouching condition. The << perform action >> would be the player losing a life.

OHHHH, I just saw the problem after reading your comment danpost, thank you so much, you are a really big help!

Thank you so much! Just what I needed

How would I do that?
