How to import greenfoot in bluej i.e how to get a greenfoot object in bluej project ??

I have a Progress bar/Health bar class scenario included in my Support Classes by danpost collection. It contains a class for a generic bar with all the needed methods for controlling it. You can download it and check it out (see how it works). You could also check out my Value Display Tutorial scenario which explains all about displaying values in greenfoot (including bar objects).

I think he means a simpler access.

Okay -- so you are not using the same Ash object in both the inside and outside worlds (that is alright -- just something that is good to know for providing more helpful assistance). You need first to track the state (not just check the state) of the Ash object intersecting the Tent object. So, you can change the Tent class to this:

Sorry. Remove 'getWorld().' from the beginning of that code.

@CodingIssues, you should start a new discussion about your issues; however, I can say the you have an excess number of squiggly brackets. Remove the first two (a closing and an opening one) after the 'if' statement and remove the last three given in your code above. Another issue will be that 'a' will only be '100' once and if the random number does not come up '1' at that one time, no Lives object will ever spawn. You should probably remove one of the two 'if' conditions for spawning a Lives object. Removing the first one will probably cause too many of them to be spawned and the random

You don't need to pass this 'playertwo' object. Since you are using the code in the PlayerTwo class, you can just use 'getY()' instead of 'playertwo.getY()'. The errors comes up because 'playertwo' is null (Pong World line 15) and you are trying to get the y coordinate of null. To the last question: you can decrease the speed of the ball or move half the way of its speed twice each act cycle and check for collision twice. (You can split it up more often if needed.)

Yeah. Well, to show how you could do it using the conditional equality symbol: <Code Omitted>This would work because the object referred to by movementDirection is either that of LEFT or RIGHT (provided any

Alright, thanks! It just gets a bit confusing and ugly sometimes.

I do not see why not. It would basically be like renaming the Creature class to Robot, then adding the code for picking up/holding/dropping off objects.

Thank God, I've found the problem. I tried to add the character to the character-selection world to see what is happening and why it's not working. As soon as I click on the button, which is supposed to add my character, the character appears and falls down to the edge of the world, because I told him to fall as long as he doesn't touch the ground (kind of gravity). I checked the coordinates (I've forgot that I changed the map and that the ground was much higher now) and saw that he spawns right in the ground and thats why I didn't saw him. I changed my coordinates and now it works perfectl

Not unless you have more issues. Again, you would have to supply any related code and give a brief explanation as to what should happen and what is currently happening that should not. My last post was just letting you know that I created a class that give actors the ability to orbit around a specific point or a specific actor. It is better than the code given above because the orbiter is more precisely moved and placed (the orbit is more precisely defined). It ha
