Pathfollower and detection of objects

By kartikitrak, with no replies.

Is it possible to make a chain of objects follow a predetermined path in greenfoot and still know that the individual objects in the chain are still seperate objects? For example, random types of orbs come out of no where and link to other orbs to form a chain and this chain follows a path. Luxor Evolved is a good example of this. In the game the orbs are spawned and then follow a path and link up on collision with another orb and then you're supposed to shoot the orbs with the corresponding color orb and when your shot blue orb touches a blue orb that was part of a chain both orbs remove themselves. (That was a lot of orbs) <Image Omitted>

Thinking it through logically, to turn toward the closest pig, this is what needs done: 1) find the closest pig by starting at distance of 1 and incrementing distance until pigs found in range or out of range by this pseudo-code: <Code Omitted> 2) upon exiting the loop, pigs in range List will either be empty or ... not; close with this pseudo-code:

Help for mouse.

By h123n, with 4 replies.
Last reply by danpost, over 13 years ago:

You need an instance boolean variable (or field) to track 'mouse pressed on me, and not yet released' or 'dragging'. Set it to 'true' if mouse pressed on this object. Set it to 'false' if the mouse is clicked (released) anywhere (use 'null' as parameter). Write an 'if' block to follow the mouse (SPower's code, but using 'if (dragging && Greenfoot.mouseMoved(null)) {' in line 1).

Lists

By JayWood860, with 6 replies.
Last reply by danpost, over 13 years ago:

A list is an object, yes; but, it is an abstract object and cannot be displayed as such. Really all you have are a bunch of String object (which also are abstract). What needs done is to create objects to draw the strings on and display them, which you can accomplish by way of a list component gui or by coding it yourself (I prefer to code things myself, as then I am not restricted in any way as to how to do things and what can be done. The drawback to this, though, is the time factor. On the plus side, however, is the experience of the journey to accomplish this task; the knowledge

Hello davemac thanks for your help. I found an explanation in German. See: http://www.rootz.de/2011/02/debian-6-0-squeeze-java-apps-haben-probleme-mit-netzwerkverbindungen/#more-1966 which links to http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=560044 it says to do sudo sed -i 's/net.ipv6.bindv6only\ =\ 1/net.ipv6.bindv6only\ =\ 0/' /etc/sysctl.d/bindv6only.conf sudo invoke-rc.d procps restart now greenfoot starts.
