/*
   This example demonstrates how to set up an event obstacle using the SetEventObstacle command
*/
NewScene( null, false );

// Add a particle cloud with a disc emitter and use its primitive to get the particle type
var pcloud = CreateParticleCloud( "", "Disc" )(0);

// Add a grid that will serve as its obstacle with some animation on it that moves it
// across the x-axis (positive to negative)
var grid_obs = CreatePrim( "Grid", "MeshSurface" );
grid_obs.ulength = 4; grid_obs.vlength = 4;  // Shrink it in half

// moves across the screen
