AddPhysics

Hello World

Content:
- Methods

Adds the Box2D physics engine to your game.

phs = gfx.AddPhysics( gravity, accuracy, sleep )

The method list below shows the functions which are added to game objects when using physics.

Example - Billiard

cfg.Game;

function OnLoad()
{
    gfx.AddPhysics(0);
    gfx.Enclose( -1, "left,top,right,bottom", 1, 0.9, 0 );

    ball1 = gfx.CreateSprite( "/Sys/Img/Forward.png" );
    ball2 = gfx.CreateSprite( "/Sys/Img/Forward.png" );
}

function OnReady()
{
    gfx.AddSprite( ball1, 0.2, 0.6, 0.16 );
    ball1.SetPhysics( 1, "Dynamic", 0.5, 0.8, 0.01 );
    ball1.SetVelocity( 2, -2.3 );
    ball1.SetShape( "round" );

    gfx.AddSprite( ball2, 0.5, 0.6, 0.24 );
    ball2.SetPhysics( 1, "Dynamic", 0.5, 0.8, 0.01 );
    ball2.SetVelocity( 2, 2.3 );
    ball2.SetShape( "round" );

    gfx.Play();
}
