Zyps

With this release, the Zyps project welcomes a new contributor, Jim Vallandingham.

New features:
Clock now lets you speed up or slow down global time. A corresponding control has been added to the GUI.
New actions - SpawnAction, ShootAction, ExplodeAction. These should make it easy to build a 2D shooter game now.
A new condition - ElapsedTimeCondition.

Behavior#perform changed to call start(), do() on all actions if no Conditions specified.
do() for all actions changed to allow empty target list.
Turn action now unconditional in GUI.
Added WrapAround to environmental factors.

This version offers considerable speed improvements, thanks to better caching of distance and angle calculations and a simple scheduler for Behaviors.

Re-added ‘click here’ message to GUI.
Trails mode didn’t play nice with resizing or messages, so removed it.
Brightened default creature color in GUI.
