```Code:

************

"Making a World of Agents and Stuff"

makeNewWorld[agents_]:=Apply[Join,Partition[Riffle[RandomReal[{-10,10},{agents,3}],RandomInteger[9,{agents,3}]],2],1]

makeNewStuff[resources_]:=RandomReal[{-10,10},{resources,3}]

agentlocations=makeNewWorld[10][[All,1;;3]];

stufflocations=makeNewStuff[5];

"The Problem of Movement"

"Agents search for nearest stuff and move along the vector between their
current position and that of the stuff."

Steplist=NestList[#+Sign[stufflocations[[Map[First[Ordering[#,1]]&,Outer[Norm[#1-#2]&,#,stufflocations,1]]]]-#]/10.&,agentlocations,2000];

Manipulate[ListPointPlot3D[{Steplist[[j]],stufflocations},PlotStyle->PointSize[Large]],{j,1,Length[Steplist],1}]
*************

How could I alter this code so that at each iteration an IF statement (or
multiple IF statements) is applied to the agents, allowing them to, say,
ignore stuff that's already found by another agent?

I've been trying to figure it out on my own for weeks... My idea's outpace
my intelligence...
