Phun is a free game like 2D physics sandbox where you can play with physics like never before. Children, students, engineers, artists, university professors, and many others, use Phun for telling stories, learning, constructing amazing machines, creating games - or just for the plain fun of it.

 

 

If you head over to phunland, you can download the application. Open up the image and copy the application and supporting files into a new folder within your application. You can then run the application and start playing with Physics.

 

Phun is an educational, entertaining and somewhat (!) addictive piece of software for playing around in a 2D physics sandbox in a cartoony fashion. Phun is not just another game, but is intended to bring in interactive physics as an enabling technology for entirely new concepts and usage patterns in creative computing for animation, simulation, narrativity, engineering, art and education. We believe that Phun is just the beginning…

 

 

Phun was developed by Emil Ernerfeldt in his MSc thesis project at the Department of Computing Science at Umeå university, supervised by Kenneth Bodin, VRlab/HPC2N.

 

Originally, the MSc project that lead to Phun was announced by Kenneth Bodin as a project for a the science center, Umevatoriet, in Umeå. However, Emil went way beyond this and Phun has found its way to a much, much larger audience on the Internet. Phun is indeed also installed at Umevatoriet, where you can run it on large HD monitors.

 

Ok, so we now have a screen with 27 buttons on it. Now what do we do? The top bar is the menu bar, and gives access to open other bars and controls. Pretty self-explanatory. The bar underneath that bar, is the sim control bar. As the name suggests, it controls the simulation (starting, stopping, undo, redo…)

 

TIP: You can also start/stop the simulation with the space bar

 

Then there’s another bar, which is called the tool bar. From left to right we see:

 

  

1. sketch tool : The most versatile tool.  Hold down the mouse button and draw a closed shape to make… a Polygon.  Hold down shift to draw straight lines.  Draw a circle inside of a shape to add a hinge.  Draw a shape around other shapes to select them.  Draw a / through an object(s) to delete it.  Draw an X to create a Fixate,  a zig-zag for a spring.
2. brush tool : Very Similar to the Sketch tool, with the following exceptions:  It cannot draw inside objects and it cannot draw hinges.  You can move objects by clicking on them with the brush tool and moving them.
3. box tool : Hold down the mouse button and drag to create a box.  Hold down shift while drawing to create a square.  Enclose objects in a box to select them.  You can move objects by clicking on them with the Box Creation tool and moving them.
4. circle tool : Hold down the mouse button and drag to create a Circle.  Nothing Special about this tool.
5. plane tool : Hold down the mouse button and drag to create a plane.  Hold down shift to rotate it at 15° intervals.
6. chain tool :  Hold down the mouse button and drag to create a chain.  Hold down shift to create a straight chain.  Circle size is dependent on the Zoom factor at creation.  You can connect them to objects or the background.
7. spring tool : Hold down the mouse button and drag to create a spring.  You can connect them to objects or the background.
8. fixate tool : Click on an object to fixate it the another object or the background.  A + in the middle means the object is fixated to the background.
9. hinge tool : Click on an object to add a hinge to it.  You can hinge to objects together, or to the background.  A + in the middle means the object is hinged to the background.
10. pen tool : Click on an object to add a pen to it.  Pens leave a little (or large) trail behind them.
11. drag tool : Click on an object and drag it around to “drag” it will the simulation is running.
12. scale tool : Click on an object(s) and drag the circles in the box/outline to scale the object.  Hold shift to scale both axes equally.  Hold Ctrl to scale in 15° integers.

So that’s twelve tools, which might sound scary but it’s pretty easy once you get the hang of it! You’ll see all tools used during the rest of this guide

 

There are also a couple of mouse controls to understand.

 

1. left mouse button: either draw or move things..depending on which tool you are using
2. right mouse button: normally it’s used for rotating, but when you drag the right mouse button on empty space, you can pan
3. middle mouse wheel: scroll to zoom in and out
4. left and right mouse buttons at the same time: pan the view
