Hi all, I used to use MASON all the time, but it's been a couple of years since I last used it until this week. I recently downloaded MASON 20 and used it to construct a new ABM, but for some reason, nothing Steppable appears to be getting scheduled. I have classes that implement Steppable, and constructors like the following (AgentsSimulation extends SimState): public Stoppable event; public Community(AgentsSimulation as){ this.event = as.schedule.scheduleRepeating(this, 1, 1); } However, even though I've confirmed these objects are being created (in the start method of the SimState), they never run their step function. Any likely culprits? My IDE is Eclipse and I'm using Java 8 (JRE 1.8). Thanks! -Paul __________________________________________________________ Paul Smaldino, Ph.D. Assistant Professor, Cognitive and Information Sciences Faculty Member, Quantitative and Systems Biology Graduate Group University of California, Merced http://secure-web.cisco.com/19bJiOoi7vgJbWF3pgTKMg5S3VpStpsb3g0_LPVwBk5Ej2Y7rWmXMj05rJ2P3hx9JIJS-N4gFhEK2f_poGV59p7borVEJgsjvl4wNxfqo28qLSJMd6GBI8QSExsqOTDXv9I6hR00qCTWnTFCAm6IPqSYIiZFZnsrE82rDdcc6ETi_6yBN2_xAFbDLmSWQ5-ScMltKZpFiqsAoISaSW49uy2u9wh4q5MScsXGW8dZY7TZh7a0ErwWPX5lmL8yn9hcmgi-XDBHv35gEdbLysVVTUCNOgU6S0cd_eD3bz-ovk7T0aGQBBkOey8duXNf4JxjLmhIb62bH1oJ6M8kTn1WPydmGBr0odV6UbYFFM58jupW4ASfE5zWqI6G0TYFRfhogPwCWzDyNjTC5vyWgFLcEiCXQzkcbZgxBfbjYxDf6BpF2JmmGa_Edj9M0dO0MavboPzuJcC2Bh6MyEdDS9WL2_A/http%3A%2F%2Fwww.smaldino.com
