Zhysics is a vector based physics simulator and object editor for the TI calculator, inspired by Soda Constructor (Google it!). It is a fairly small program (less than 2 kilobytes). Load ZHYSICS and ZHYSICS1 onto your calculator, and run ZHYSICS to use it.

You will see the main menu upon starting the program. If it is your first time using Zhysics, select "NEW" to create a new object. You will be brought to the object editor, where you can make an object to be simulated. There are 4 modes for building an object. Press the STAT key to switch between modes. You begin in create mode, which lets you make a point. Use the arrow keys to move the cursor, and the ENTER key when you have decided where you want the point to be. After creating a point, you switch to connect mode, which lets you connect points together. Use the Y= and WINDOW keys to switch between points, and the ENTER key to select a point. If it says "CONNECT 1", the program wants you to select the first point to connect. If it says "CONNECT 2", then it wants the second point. When you select the second point, the points are connected by a line. Move mode lets you move a point around with the arrow keys. In delete mode, select a point, and press the ENTER key to delete it. The calculator can create as many points and connections as you have ram. The more points and connections you make, the slower the simulator will run. When you are done creating your object, press the MODE key to simulate it.

In the simulator, your object will move and you can interact with it. Use the Y= and WINDOW keys to switch between points, and the arrow keys to apply a force on the point. Press MODE to return to the main menu. In the main menu, "EDIT" will let you edit your current object in the editor, and "PLAY" will simulate it.

Zhysics uses L1 and L2 to store your object's data. If you have altered these variables, or if a program has altered these variables, Zhysics will not be able to play or edit your object, so you will have to make a new one.
