Help with converting a buffered image into a greenfoot image
By AppleBanana, with no replies.
Hi, I was trying to write a program, that converts the sprites from a sprite sheet into an actual animation. The problem I stumbled upon, is that I now need to convert a buffered image into a greenfoot image, but my mental capacity clearly isn't as big enough co comprehend such an action, so help would be much appreciated :) the error itself is in the animationShower() method, but i'll post the whole class, just for clarity the code: <Code Omitted>

Your implementation idea is correct. There are just some minor mixups: << List Omitted >>
Notes about the list: (1) The default value for
boolean
fields is
false
, so it is not required to add "
= false
" to line 11; (2) This may not be necessary if the objects created are equivalent each time. This will become apparent after moving on to (3) below; (3) The state of being "open" can be determined by a simple check, without the use of a boolean field. Note the code below:

I have collision code that works well. You can't move up or down through blocks. There's also code for walls, but whenever I enable them, moving left and right on tiles is messed up. My game is tile-based, and I don't think the code is really meant for moving on multiple tiles at a time.
Please clarify: * tile based: how is your world created? please provide the
super
constructor call line in your world constructor; if the third value is 1, then please explain what you mean by tile based. * moving multiple tiles at a time: does this mean skipping over some

I want to make my actor (SoldierShip) detect if there is another type of ship nearby. I don't think I have any code that would help

Need Help with Collision

Basically, after moving, if an obstacle is touched, then move back. For example, after line 36, which moves Mario horizontally: <Code Omitted>} A bit more is involved when moving vertically when gravity is in play. See what you can do with it.
