Create a Object2dDisplay, give it a Raster widget to draw on, a Discrete2d, a message to call on each object, and (optionally) a collection of objects and it will dispatch the message to all objects with the Raster widget as an argument. In addition, Object2dDisplay can help you make probees. </P></DIV><DIVCLASS="REFSECT1"><ANAME="AEN23301"></A><H2>Protocols adopted by Object2dDisplay</H2><P> <AHREF="swarm.objectbase.swarmobject.protocol.html">SwarmObject</A> <AHREF="swarm.defobj.creatable.protocol.html">CREATABLE</A></P></DIV><DIVCLASS="REFSECT1"><ANAME="AEN23306"></A><H2>Methods</H2><DIVCLASS="REFSECT2"><ANAME="AEN23308"></A><H3>Phase: Creating</H3><P></P><UL><LI><DIVCLASS="FUNCSYNOPSIS"><ANAME="SWARM.SPACE.OBJECT2DDISPLAY.METHOD.PC.M12"></A><P></P>+ <BCLASS="FUNCPROTOTYPE">create:</B> (id <Zone>)<VARCLASS="PDPARAM">aZone</VAR> <BCLASS="FUNCPROTOTYPE">setDisplayWidget:</B> (id <Raster>)<VARCLASS="PDPARAM">r</VAR> <BCLASS="FUNCPROTOTYPE">setDiscrete2dToDisplay:</B> (id <Discrete2d>)<VARCLASS="PDPARAM">c</VAR> <BCLASS="FUNCPROTOTYPE">setDisplayMessage:</B> (SEL)<VARCLASS="PDPARAM">s</VAR> <BR> Convenience constructor for Object2dDisplay<P></P></DIV></LI><LI><DIVCLASS="FUNCSYNOPSIS"><ANAME="SWARM.SPACE.OBJECT2DDISPLAY.METHOD.PC.M743"></A><P></P>- <BCLASS="FUNCPROTOTYPE">setDisplayWidget:</B> (id <Raster>)<VARCLASS="PDPARAM">r</VAR> <BR> Set the display widget to use for drawing.<P></P></DIV></LI><LI><DIVCLASS="FUNCSYNOPSIS"><ANAME="SWARM.SPACE.OBJECT2DDISPLAY.METHOD.PC.M737"></A><P></P>- <BCLASS="FUNCPROTOTYPE">setDiscrete2dToDisplay:</B> (id <Discrete2d>)<VARCLASS="PDPARAM">c</VAR> <BR> Set the 2d array to draw.<P></P></DIV></LI><LI><DIVCLASS="FUNCSYNOPSIS"><ANAME="SWARM.SPACE.OBJECT2DDISPLAY.METHOD.PC.M740"></A><P></P>- <BCLASS="FUNCPROTOTYPE">setDisplayMessage:</B> (SEL)<VARCLASS="PDPARAM">s</VAR> <BR> Set the message to be sent to each object in the grid to make it draw itself. <P></P></DIV></LI></UL></DIV><DIVCLASS="REFSECT2"><ANAME="AEN23353"></A><H3>Phase: Using</H3><P></P><UL><LI><DIVCLASS="FUNCSYNOPSIS"><ANAME="SWARM.SPACE.OBJECT2DDISPLAY.METHOD.PU.M811"></A><P></P>- <BCLASS="FUNCPROTOTYPE">setObjectCollection:</B> <VARCLASS="PDPARAM">objects</VAR> <BR> Set a collection of objects to be displayed.
