new data type ....
Problem: I want to define a new data type (for example, the data type is
a structure), at a global level, such that this type can be used by any
agents in any swarm. I used tutorial/simpleObserverBug programe to test this
idea. In main.m, I added some codes like:
typedef struct node Node;
typedef Node *PtrNode;
struct node {
int xxx;
float yyy;
PtrNode link;
};
and in ModelSwarm.m, in a method definition (e.g., buildobjects), I try to
define a temporal variable such as:
Node n1;
PtrNode ptr;
however, when I compiled the newly modified codes, the error message says
Node and PtrNode has not been declared.
I am not sure whether this is my C knowledge is wrong (I am a moderate level
C programmer), or Swarm agents does not recognize global data type definition.
Thanks!
