Line 4 is not where the spacebar is only down. Its state is not determined until after line 5. An else clause following the if block (lines 5 thru 8) would be used for key down state. Line 4 is only for a unknown change in the state of the spacebar.

In the DUP class code, add the following line after line 18: <Code Omitted>Then, in the act method, add the following line after line 34: <Code Omitted>These lines will immediately cause an exit from the methods so that no further code that require the actor be in the world be executed.

Of course, since we didn't cover how to use the results of getObjects (or even mention the get() method), there must be another (much simpler) way to do this!

You could keep a reference to the Runner object in your World subclass along with a "getter" method: <Code Omitted>Then, use the following in your Actor subclass:

sending variables between 2 files

hello. im new to greenfoot, and im trying to create a board game where the board of the game is revealed to all players but each players hand can only be seen by that player. i created two different greenfoot projects and am trying to send a variable between them so one project can influence the other. tried doing this with an abstract java class but it doesnt seem to work a) is there a way to get two projects to communicate with each other? b) is there a better way of creating a game like this? thanks

How could i save all the states of my main world, create a different one, lets call a battleWorld, do some stuff in it, and then go back to the main world without resetting everything (saving the progress). For example i have the main world where the player walks around, if the player comes in contact with some particular object then it will initiate battle and once the battle ends the world will continue running where it left off. Not too sure how to implement this. I was told that a possibility could be to create the new "battleWorld" and have it point to the original world

How do you restart the level when the player touches the ground?

Yep, I did that. But I keep falling through platforms from a great height. I know that the direction of movement will determine whether the player should be placed above or below the object it collided with but I don't know how I can alter my original code.

Line 76 ;should probably use the getOneIntersectingObject method instead of the getOneObjectAtOffset one. You can add another condition to line 77 such that the vertical speed must be positive.

Character Falling Through Floor

By Underdemon, with 19 replies.
Last reply by danpost, over 6 years ago:

Wow -- I had no idea you were talking about a thin line of green. As such, you might be better off adding Ground objects into the world -- just invisible rectangles whose top edges line up with the horizontal green lines. The Ground actors can then be used to prevent the "falling through" issue. Let us fix the "subclass doesn't change" issue later and worry about the "falling through" right now.
