Advanced Mouse Control

With the help of some people on the Discussion forums, I have created a very small demo scenario that demonstrates how to change the image of the mouse cursor in Greenfoot, as well as how to read from the Scrollwheel

If you look at the source code, you will notice that the Image of the mouse that I am using is actually an actor. This is because not all computers support full color on mouse Images and so I merely disable the mouse image entirely and substitute with an Actor image.

Both of these exploits rely on a tricky piece of code provided by Davmac, and there is no guerentee that they will continue to work in future versions of Greenfoot.

Enjoy the code and use it in all your Greenfoot Scenarios :D

All fixed :] I tend to write these descriptions pretty quick, and without the luxury of spell-check :P

I just saw this and got excited to implement scrolling through something such as a page vertically. But I don't see a way to also scroll horizontally. Don't know what that would consist of. On a track pad on my mac I can scroll vertically and horizontally with similar motions. And I believe on a typical mouse, when you press in the scroll wheel you can do the same thing.

Works vertically nicely though =)

My normal mouse hovers over the dot

Is there any way to set it back to default? If I want to use it in one world (at least similar as how you have it), but change from that world to another, how to I get the original cursor back (without clicking on reset and set the world manually)?
