3DS Physics Sandbox is a homebrew that allows you to play around in an environment with simple physics.
==Features==
* Manipulate multiple different sized squares with the stylus.
* Objects will bounce off of each other.
* The squares are affected by gravity, with walls and friction.
* Modifiable gravity, collision elasticity, and friction values.
* Collisions calculation uses momentum of squares.
* Take a screenshot.
* Control gravity by tilting 3DS (accelerometer).
* Move camera with circle pad.
* Walls that squares will bounce off of.
* Different squares and walls can be made using on screen UI.
==Installation==
===Installing===
Available in 3DSX and CIA formats.
* CIA - Install the .cia with the CIA manager of your choice.
* 3DSX - Use the .3dsx provided with the Homebrew Launcher.
===Building===
This requires sf2dlib and expects the libsf2d directory to be in the same directory as 3dsphysicssandbox. Just run the makefile to build.
==Controls==
Tap and Drag square - Move square
X - Reset entire world
B - bring selected square back to center of world
D-Pad Left/Right - Change modifiable value
D-Pad Up/Down - Increment current modifiable value
L/R - Change increment (multiply and divide by 10)
Circle Pad - move camera
Y - toggle gyroscope as gravity
Select - Save screenshot
Start - Exit

An application for messing with physics on the 3ds ###Current Features:
If squares are traveling fast enough, they can clip through walls (more apparent in smaller squares).
* Manipulate multiple different sized squares with the stylus
 
* Objects will bounce off of each other
Sometimes squares get crushed against vertical walls because of x gravity.

*Added support for up to 32 squares.
* Control gravity by tilting 3ds (accelerometer)
*Added walls, immobile objects(lines) that objects bounce off of (up to 32).
* Move camera with circle pad
*Removed square bouncing on edges of screen (by default replaced by walls in the same locations).
* Walls that squares will bounce off of
*Added camera, use circle pad to move view around.
* different squares and walls can be made using on screen ui ###Plans for the Future:
*Updated UI:
* Fix Banner Sound (Warning: sound may be irritable)
**Now contains two columns of information, global variables and object specific variables.
* Save and load state to and from file (coming v0.4)
**Change the mod_val scope to switch between these two.
* Different kinds of objects (like circles or custom shapes)
**All data of squares and walls can be modified (position, size, etc).
* Proper implementation of forces and vectors
**Use obj_type to change between squares and walls.
* Tension and ropes
**Use curr_view to change which object you are looking at.
* Develop into physics library
**Use coord to change the objects position.
* 3D physics ###Building: This requires sf2dlib and expects the libsf2d directory to be in the same directory as 3dsphysicssandbox.

3DS Physics Sandbox is a homebrew that allows you to play around in an environment with simple physics.

Features

  • Manipulate multiple different sized squares with the stylus.
  • Objects will bounce off of each other.
  • The squares are affected by gravity, with walls and friction.
  • Modifiable gravity, collision elasticity, and friction values.
  • Collisions calculation uses momentum of squares.
  • Take a screenshot.
  • Control gravity by tilting 3DS (accelerometer).
  • Move camera with circle pad.
  • Walls that squares will bounce off of.
  • Different squares and walls can be made using on screen UI.

Installation

Installing

Available in 3DSX and CIA formats.

  • CIA - Install the .cia with the CIA manager of your choice.
  • 3DSX - Use the .3dsx provided with the Homebrew Launcher.

Building

This requires sf2dlib and expects the libsf2d directory to be in the same directory as 3dsphysicssandbox. Just run the makefile to build.

Controls

X - Reset entire world

B - bring selected square back to center of world

D-Pad Left/Right - Change modifiable value

D-Pad Up/Down - Increment current modifiable value

L/R - Change increment (multiply and divide by 10)

Circle Pad - move camera

Y - toggle gyroscope as gravity

Select - Save screenshot

Media

3DS Physics Sandbox v0.3 (PieFace)

Known issues

If squares are traveling fast enough, they can clip through walls (more apparent in smaller squares).

Sometimes squares get crushed against vertical walls because of x gravity.
