Can you open that up or give a hint about the concept where I can read more? The run sequence is like this right? Space/ Constructor Vector / Constructor SmoothMover / Constructor Body / Constructor
Let me just point out a thing here. When an
Object
instance is created, it is created from the bottom up. All extending classes are built on their supers. So, when you create a body, the
SmoothMover
portion is created before the
Body
portion. Think of it as such that the
Body
object inherits pre-defined traits provided by the
Smo

The jump should be made slower
By Flantox, with 1 reply.
Replied to by danpost, 17 days ago:
The one way that will most surely work is to use a smooth movement system on the actor so that you can use a "fractional" acceleration value. A slower than one acceleration will make your actor jump a bit higher, while doing so at a slower speed. See my
GQActor Superclass Demo
scenario for a demo (or download to look at or use). Adjust the gravity value, which is vertical acceleration, for the effect.

Yeah sure, I will look into it. Would you tell me how I can interact with my classes? I thought its public first but I didn't found anything. So..should I use "static" for those purposes?
Again, probably not. But, cannot tell for sure. Must be considered individually.

<< Quote Omitted >> so what does this exactly do? So i can understand it :). Also what I meant was i want to check all the 8 neighbours of a black cell. And for every white neighbour within the 8 cells, a variable (i) should increase by 1.
Well, your title suggested you wanted to know if any White objects were neighbouriing a Black (order of colors not being pertinent). However, now you specify you need a count of them. For number of neighbors: <Code Omitted>This will give the current number of Wh

There are some control codes below 32 that will either not print or perform their intended operations (BS=8, LF=10 and CR=13, to name a few). There may be one more that lies between 32 and 100. There are many above 256 that are either unassigned or will display as a small unfilled box. I do not think you can do anything about how they display in the greenfoot terminal.

Background sound fades when another sound is played
By Libraoct7, with no replies.
I have created a simple game in which an object (boy) eats all the cherries avoiding snakes and bombs. When the game starts, a background sound is played. When the boy eats a cherry, a pop sound is played. But when the pop sound is played, the background music is faded where you can't even hear it until about 7 seconds later that would the background sound is heard. Please help me to fix this problem. This is my MyWorld class: <Code Omitted>This is the Cherries class: <Code Omitted> And this the boy class: <Code Omitted>
