Someone named Tim Edmonds is working on such project already... It compiles and already is much fun... :)

Re: Crayon Physics & internet tablets: made for each other
 

I could get Petri a used 770 easily...

Re: Crayon Physics & internet tablets: made for each other
 

I think that's Samoff, not Sarnoff...

Re: Crayon Physics & internet tablets: made for each other
 

Going to have to figure out how to compile, haven't delved that much into the n800/linux. This little app looks like it would be a blast.

Re: Crayon Physics & internet tablets: made for each other
 

If you like Crayon Physics, you'll probably also like Phun.

Youtube video:

You can download Phun for free at
http://phun.cs.umu.se/wiki

Basically the same concept. Didn't have a closer look at this Crayon Physics stuff, but I think Phun is even more powerful as it also supports particle/water simulations.

Though I wouldn't hold my breath to see Phun on the NITs soon, as (at least with extensive particle simulation) it can even bring my 3 GHz P4 down to it's knees.

Edit: just saw, that Phun is already linked in the first post of this thread.

Would a flash version be easier to create?

Re: Crayon Physics & internet tablets: made for each other
 

Yes, you're right. I've corrected it.

Thanks for bringing this my attention (especially since it was my inattention that led to the typo).

Re: Crayon Physics & internet tablets: made for each other
 

Maybe, but a hell to run on this hardware.

Re: Crayon Physics & internet tablets: made for each other
 

I hope numptyphysics is as much fun and as well thought through as Crayon Physics Deluxe.

But, well, to take a mundane example, there are all sorts of Sudoku implementations and all sorts of Solitaire. And even though they "do the same thing" some aren't worth playing and some are great.

What I know about Crayon Physics and CP Deluxe leads me to trust it'll be great on the IT.

Re: Crayon Physics & internet tablets: made for each other
 

Maybe. Lots of power in Flash to do these things.

But the shape creation might not be so easy . . .

Then again, there are some things I have no idea how they're done, so I'm talking through my hat to say yes or no.

Re: Crayon Physics & internet tablets: made for each other
 

hey - that's me! i was planning on cleaning it up a bit more before
announcing it but you beat me to it. glad you like it. i suppose i
will need to hurry it up now.

more info here: http://numptyphysics.garage.maemo.org

Re: Crayon Physics & internet tablets: made for each other
 

I think you're right. I think Phun! is too big to bring over.

And Phun! is pretty interesting, but, well, I reacted to it differently than Crayon Physics, which is a game truly.

Re: Crayon Physics & internet tablets: made for each other
 

Crayon Physics and Numpty Physics use the same 2D engine, namely Box2D. Not sure if this engine has been ported to flash.

Re: Crayon Physics & internet tablets: made for each other
 

Yes, and make a YouTube video so we can share it with the world!

Re: Crayon Physics & internet tablets: made for each other
 

Sorry i gave you up ;)

Re: Crayon Physics & internet tablets: made for each other
 

It wouldn't need to be. Flash has its own engine.

I don't mean any sort of porting, but rather, a fresh coding effort using Flash from the start.

Re: Crayon Physics & internet tablets: made for each other
 

I have compiled it in 5 minutes and it works very nice. It's AWESOME.

Thank you very much, it's a great work.

Re: Crayon Physics & internet tablets: made for each other
 

Flash is still underpowered on the tablets, maybe for the desktop.

Re: Crayon Physics & internet tablets: made for each other
 

Then again:

EDIT: Very slow :)

Re: Crayon Physics & internet tablets: made for each other
 

So far the flash games I've downloaded to run offline on N800/N810 work great... but I understand that doesn't mean they all will.

Re: Crayon Physics & internet tablets: made for each other
 

ok guys and gals. you've caught me on the hop but i've uploaded a deb for you to play with and make youtube videos etc. enjoy but remember it's a dev snapshot and not-ready-yet. levels and fixes welcome as i'm really short of time to spend on this lately.

Re: Crayon Physics & internet tablets: made for each other
 

Accelerometer anyone?
I have to say that that would be wicked.
Possibly through serial via usb or just usb? (just usb sounds harder)

Re: Crayon Physics & internet tablets: made for each other
 

I saw recently where someone actually developed one. The thread is here, somewhere...

Re: Crayon Physics & internet tablets: made for each other
 

Cheers tme :)

I acquired the sources to PocketPhysics on the DS from the author who was more than happy to share. Unfortunately I haven't had time to do anything useful with them (i.e. strip the DS specific code.) Now I know I won't need to add this to my list of projects ;D

I've not tried tme's numptyphysics yet - but if the physics simulation is slow and assuming you've not used it yet - there's a fixed math implementation of the Box2D library available that may make simulation faster.

Re: Crayon Physics & internet tablets: made for each other
 

is there any way to clear the page so you have a totally blank sheet of paper?

Re: Crayon Physics & internet tablets: made for each other
 

start with a simple level (like L3) and delete using zomme-minus plus stylus.

Re: Crayon Physics & internet tablets: made for each other
 

This is great! I can't believe how smoothly it works. Looking forward to future developments...!

Re: Crayon Physics & internet tablets: made for each other
 

His app is not slow, we were talking about possibility of a flash implementation.

Re: Crayon Physics & internet tablets: made for each other
 

I tried numpty physics but the install cacks out wanting libc6 >=2.5... which looks to only be available for Chinook, Bora (read: HackerOS2007) only goes up to 2.3.5.

Well. It was a neat idea, back to using my 770 as a paper weight. :)

Re: Crayon Physics & internet tablets: made for each other
 

OS2008HE is available and (in my opinion) quite usable. . . .

Re: Crayon Physics & internet tablets: made for each other
 

Naah, OS2008HE doesn't help the Illegal instruction i get in 770 :(

Re: Crayon Physics & internet tablets: made for each other
 

this is built with -mcpu=arm1136j-s -mfpu=vfp -mfloat-abi=softfp so will almost certainly have trouble on the 770.

i've added a build without these options - let me know if it works and how well.
https://garage.maemo.org/frs/downloa...08he_armel.deb

Re: Crayon Physics & internet tablets: made for each other
 

I was also going to post such build with these options:

-mcpu=arm1026ej-s -march=armv5te -mfpu=vfp

It is here (i got the source yesterday):

Re: Crayon Physics & internet tablets: made for each other
 

Tried yours - illegal instruction.

Btw, Numpty Physics is running quite good on the old 770 (provided there are not too much moving objects on the screen - the first level is an overkill, but the second is playing quite good actually).

Re: Crayon Physics & internet tablets: made for each other
 

Check out Magic Pen:

Review by John Bardinelli at Jay Is Games (emphasis added):

Magic Pen is a physics-based puzzle playground created by Alejandro Guillen (Spin the Black Circle). It's easy to see the design, from visual style to overall concept, was taken from Crayon Physics, but because Magic Pen is a Flash game, it's much more accessible. Using the mouse, simply draw shapes to create bridges and guide the red ball to the flag. Making shapes and dropping them from the sky will set the ball in motion, and you can also craft structures with hinges (both fixed and movable) for more complex maneuvers.

The shapes you draw are affected by three basic principles: gravity, friction, and inertia. In other words, common sense physics. Drawn shapes will fall to the ground, bump against each other, and sit still unless acted upon by another moving shape. You can draw just about any object you please, but Magic Pen automatically smooths out jagged edges into a more block-like shape. The entire game is mouse-driven, all you have to do is click and start drawing.

Pins and hinges link objects together and allow you to craft more complex machinery to get the ball to the goal. Hold the [S] key and click inside an object to draw a pin, then draw a second object that overlaps the "X" and it will be held in place. For a movable hinge, press and hold the [D] key and start drawing. The shape you create will be affected by gravity and slowly swing around the pivot point towards the bottom of the screen.

There are over two dozen levels in Magic Pen, each one more wickedly devious than the last. There's even a sandbox mode accessible from the in-game menu (press [Q]). The number of shapes you used to complete each puzzle is recorded, and once you beat the game you can submit your scores to see how well you did compared to other Magic Penners.

Analysis: Good-looking, simple, engaging and fun, Magic Pen is exactly what I like to see in a casual online title. The game doesn't try to hide the fact that it's a near-direct clone of Crayon Physics; Alejandro even thanks Petri Purho in the credits. One key difference is you can't do "shape bumping", or drawing overlapping objects so they pop on top of each other. And when Crayon Physics Deluxe is finally released, it will no doubt contain much more content than Magic Pen.

Magic Pen takes place in real-time, meaning once you draw a shape it's immediately set into motion. This really keeps you on your toes, but it can also be frustrating when trying to draw delicate platforms in a pinch. A start/stop mechanism would make it much more of a cerebral puzzle game, whereas the current setup feels like an arcade experience.

A great Flash experience that's fun as a webtoy and challenging as a puzzle game.

Re: Crayon Physics & internet tablets: made for each other
 

Magic Pen has one serious drawback AFAIAC: You can't play it well enough on a keyboardless tablet.

Re: Crayon Physics & internet tablets: made for each other
 

You can't play it on one with keyboard too :) For now...

Re: Crayon Physics & internet tablets: made for each other
 

Probably down to the vfp so best remove the "-mfpu=vfp" bit. I'd be tempted to remove the -mcpu bit completely and do two versions, a softfloat one for 770 and a vfp one for n8x0. If you're using a fixed point engine, then one build without any of those options would be the best bet.
