Simulation files

Simulation files control the behaviour of the program. The repository contains a simple simulation example in simulation.txt.

The syntax is as follows:

• simulation [nobj] [timestep] [gravity]: Creates a simulation with nobj objects, sets the gravity to gravity and the time interval between frames as timestep.
• window [width] [height] [bpp] [scale] [quality]: Creates a window of size widthxheight and bpp bits per pixel, sets the view scale to scale and rendering quality to quality (between 5 and 100).
• shape [restitution] [friction] box [half width] [half height]: Creates a box with size 2*half widthx2*half height, and sets its friction and restitution.
• shape [restitution] [friction] circle [radius]: Creates a circle with radius radius, and sets its friction and restitution.
• object [shape index] [flags] [mass] [x] [y] [angle] ([x speed] [y speed] [angular velocity]): Creates an object with the shape indexed by shape index (starting from 0), the given flags (STATIC=1, SLEEPING=2), mass, position, and velocity.
