Declaration

void __stdcall forEachNbr(
	int x,                               // x-coordinate of agent
	int y,                               // y-coordinate of agent
	bool (*func)(pState,int,int,         // name of function
	             pState*,int,int)
);

Parameters

x: X-coordinate of agent whose neighbours are to be processed (zero based).
y: Y-coordinate of agent whose neighbours are to be processed (zero based).
func

Remarks

This function is available through the API. It provides an efficient way to process every neighbour to the agent at (x,y) in turn. The details of this function are the same as that for forEachAgent except that the iteration is only over the neighbours of a single agent.

Revisions

API v1.5

no longer passes param to func

Example

void __stdcall onTick(double &time) { int x,y; int nbrCount; pState *nbr; pState state = anyAgent(NULL,x,y,nbr,nbrCount); forEachNbr(x,y,someOperation); }
