To make another events by yourself just call (type in console or on collision) one of functions:

To make a timer:
scene.my.newTimer(countdown, {{action}}, repeat);
for example: scene.my.newTimer(1, {{sim.running = false}}, true) will stop simulation every second.

To make an alarm:
scene.my.newAlarm(time, {{action}});
for example: scene.my.newAlarm(10, {{scene.camera.pan = [0,0]}}) will move focus to 0,0 at 10 second of sim.

To make custom event:
scene.my.newEvent(time, countdown, count, {{action}});
for example: scene.my.newEvent(7, 1, 10, {{scene.addCircle({pos=[0,0]})}}) will spawn 10 circles one by one every 1 sec after 7 sec sim time.
