Method Inst_MoveTarget

avida-core/source/cpu/cHardwareCPU.cc:8903–8940

This command should move the organism to the neighbor cell that is a target. If more than one target exists, it moves towards the last-seen one. If no target exists, the organism moves forward in its original facing.

// one.  If no target exists, the organism moves forward in its original
// facing.
