Declaration

int __stdcall getNbrY(
	int x,      	// x-coordinate of agent
	int y,      	// y-coordinate of agent
	int nbrIndex  	// index of neighbour to get coordinates of
);

Parameters

x: X-coordinate of an agent.
y: Y-coordinate of an agent.
nbrIndex: Neighbour index of agent at (x,y) to return coordinates for.

Return Value

Returns the y-coordinate of the specified neighbour of the agent at (x,y). On error returns -1.

Remarks

This function is available through the API. It can be used, with getNbrX, to get the coordinates of a neighbour to a specific site.

Example

void __stdcall onTick(double &time) { int ax,ay; int **nbr, nbrCount; int *a = anyAgent(NULL,ax,ay,nbr,nbrCount); // pick a neighbour int nbrIndex = random(aNbrCount); // 0..aNbrCount-1 // get second neighbour int bx = getNbrX(ax,ay,nbrIndex); int by = getNbrY(ax,ay,nbrIndex); int *b = xyAgent(bx,by,nbr,nbrCount); // now nbr[0..nbrCount-1] are second neighbours of a. // process second neighbours... }
