Since some users are tired of getting bugged by the alerts from the original topic. I thought I open this one.
Please continue the discussion here.

Might be double, but I experience a bug:
In the method getintersectingobjects, it only detects intersections on the corners.
@groengeel
It just won't work in a "cross" situation I think.
int ax = getX() - getImage().getWidth()/2;
int ay = getY() - getImage().getHeight()/2;
List<String> axc = new ArrayList();
System.out.println("----This:----");
for(int ix=0; ix<getImage().getWidth(); ix++) {
int dx = ax+ix;
for(int iy=0; iy<getImage().getHeight(); iy++) {
int dy = ay+iy;
axc.add(dx+","+dy);
System.out.println(dx+","+dy);
}
}
Actor other = (Actor)getWorld().getObjects(cls).get(0);
int bx = other.getX() - other.getImage().getWidth()/2;
int by = other.getY() - other.getImage().getHeight()/2;
List<String> bxc = new ArrayList();
System.out.println("----Other:----");
for(int ix=0; ix<other.getImage().getWidth(); ix++) {
int dx = bx+ix;
for(int iy=0; iy<other.getImage().getHeight(); iy++) {
int dy = by+iy;
bxc.add(dx+","+dy);
System.out.println(dx+","+dy);
}
}
for(String coordinate : axc) {
if(bxc.contains(coordinate)) {
System.out.println("Found matching coordinate: "+coordinate);
return true;
}
}
return false;I'm still on my bed actually :-)
Then how is your work going erdelf?
It 'creates' a cube around it.
Upup.., is there a bounding box in the Greenfoot4Android project?
@groengeel
The difficulty of the intersection detecting is:
what if the Actors are having rotations...

I checked my email twice but get nothing.
Again my email is:hzxjhspxn@163.com
Maybe you should send it again.
I think the most important thing to do for Greenfoot4Android is find some way to catch the Exceptions and show them up, like Greenfoot did.
So someone like erdelf would get his job more easier.
