The problem with bitmaps is that this engine uses meshes, not bitmaps.

So maybe take a look at blender source code to improve mesh editing?
I'm thinking you didn't hotkey App.drawVertices without a reason (other than debugging?)

Maybe just add support for some basic functions: mirror xyz/global/local, subdivide, drag vertice, snap to grid, duplicate, extrude...

I also do not like the idea of fire at all. Or oil.

Maybe once he releases the Source Code, presuming he does, then there will be an Elements Phun, with Fire, Oil, Plant etc. A bit like falling sand but much more complex.

This is not exactly a suggestion for Phun itself, but for the website.

I can see the page for sharing .phn files has the potential to get very large.
As the flat list that it is, it might start to get difficult to find the things of most interest to you.

A few ideas that might help organize this page:
*When uploading new files, possibly let the user pick from a predefined category list(for ex. vehicles, projectiles, experiments, phun test cases/bug examples, etc)
*Or maybe just add relevant tag words to your scene, which could later be searched on
*option to add thumbnail pics?

Maybe the upload could check the forum user login(or have it's own login), which could provide functionality such as:
*Letting users rate other user's scenes
*Allow users to update/delete their own uploads instead of having to create a whole new scene in the list each time.

If you need a web app developer, I might be able to help ;-)

and thrusters would be very useful for building rockets and so on

a grid system has been suggested before you know...

I'd love the ability to output frame-by-frame information about the motions of the objects.

At present I can take a Phun scene file and process it to create a source file for a 3D rendering system, like this:



But it would be really cool to be able to grab the information at precise regular intervals and produce a 3D animation.

One thing that has bothered me is the difficulty of setting springs.  As far as I can tell, the only way to put tension on a spring is to grab it during simulation, and try to compress it while things are flailing around.  then pause the simulation again to set it in place.

If the spring could be compressed while in edit mode (simulation paused), I think things would be much easier to build.

I can think of at least two ways to add this to the user interface:
1.  The user draws a spring in the exact final spot they need it to be, then sets a parameter that says what the natural/untensioned length of the spring should be, as a ratio of it's given length.
2.  When the user first draws a spring, the length given would represent the natural / untensioned spring length.  After drawing it, the user has the option to individually move the spring's endpoints, which would put tension on it.

I hope those explanations make sense.

I agree that the following features would be great to have in the next version:
- A scroller that adjusts the spring tension.
- Snapping to grid, maybe also snapping to geometry.
- Export animation to some vector graphics format.
- Keywords & ratings in the "project sharing" section (before it's too late!).

Also, these features seem to be nice, but need discussion:
- Different liquids (variable fluency & variable compressibility)
- Some kind of propulsion (rocket engines)
- Implement theory of relativity & quantum physics (kidding!...)

It would be nice if you could convert to/from Phun units to real world units of measurement.  For purposes such as: dimensions, spring constants, density*, etc.
I'm guessing that the units in Phun are completely arbitrary at the current moment.

*Speaking of setting density, it would be nice to have the option to set the total mass, instead of density(of course setting one would affect the other).

I think allowing the specifying of real units could help Phun become a more accurate tool, for educational and even realistic simulation purposes.
For example if someone wanted to build a trebuchet in real life, and they had already figured out the rough dimensions and weights estimates, they could roughly judge the performance of their design  in Phun before building anything.

I think I should have explosions and peoples / dolls / action figures.
It all
This game is very cool and funny

I found problem with Phun (linux 32bit), when I load some new scene, memory allocation of old scene, isn't unallocated. So program use more and more memory and at the end it freeze (system with 256MB RAM + 256MB swap).

Set App.maxUndo to something like 5 (see http://www.phunland.com/wiki/Console).

All example I saw were vertical examples (xz plan).

Is it possible to build horizontal example (xy plan), with (vertical) gravity and plan-friction ?

More generally, is it possible to buid examples on any plans ? on a 2D-curve (or piecewise-linear 2D-curve)?
