Ported Super Mario game to libgdx..

For demo click here
To learn Libgdx frame work i decided porting my android super mario game to it. It was quite a fun, digging the potential of this game framework. For those aiming to learn game development for whatever reason I will recommend libgdx, since it deploys your code to html, ios, android and desktop simultaneously.
BTW you can have a look at source code of the game

Plotter in SimPHY is rewamped !

Plotter in SimPHY is updated with several enhancements and tweaks, to make is more interactive and powerful.

The update mainly focuses on smoothing of curve/plot(which can clearly be seen in screenshot) and ability to plot graph between any two parameters rather than plot with time as x axis as in previous version.

Serpent Demo in Simphy 5.5

Demonstrates physics behind snake motion. Snake is created by joining many rectangles with revolute and distance joint.
Look at the motion of serpent closely, the joints are behaving like vertebrates.

SimPhy updated to 5.5

SimPhy is updated to new version which involves many tweaks and some long desired features. This updated is mainly intended for better visualization support to understand physics better.

Simphy Custom forces demo

You can simulate almost any 2D motion of objects by applying custom force to body. Force may be the function of speed, position, mass of object.

SimPhy Fields Demo

SimPhy supports setting up of various fields other than gravity.

  • Gravity:

    The gravitational force on an object is calculated as
    Force = mass x gravity x gravityFactor

  • Electrostatic field:

    Electrostatic field (in N/C)added to the world, apply force on object if and only if it has non zero charge and it is inside bounds of field.

  • Magnetic field:

    The magnetic lorentz force on an object is calculated asForce = charge x speed x magnetic field  and is perpendicular to the velocity

  • Buoyancy and drag:

    Buoyancy can be added to a region representing hypothetical liquid in that region. The density and viscosity of liquid can be changed while adding/editing field.

Simphy Joints Demo

Simphy has a number of ‘joints’ that can be used to connect two bodies together. These joints can be used to simulate interaction between objects to form hinges, pistons, ropes, wheels, pulleys, vehicles, chains, etc. Learning to use joints effectively helps to create a more engaging and interesting scene.

Body Types in Simphy Demo

Demo for various type of bodies that can be added to Simphy. You can also create complex bodies by adding multiple fixtures or using constructive area geometry.

Gui Elements added to Simphy

SimPHY now supports its own gui elements which respond to their associated events through scripts.
Button: allows user to write script on its onClick() event. for example

function button_onclick(){
    var disc = world.addDisc(0.3)

adds disc of radius 0.3 at origin whenever button is pressed.
