Parameters

a	Position a.
b	Position b.
map	A 2D vector of nodes.
nodeSize	The size of the node.
renderer	A pointer to the renderer.

JAM_Vec2 JAM_LOS::getNewTarget	(	JAM_Vec2	a,
		std::vector< std::vector< JAM_Node * >>	map,
		int	nodeSize
	)

Find a new target position to go to.

Parameters

a	Position a.
map	A 2D vector of nodes.
nodeSize	The size of the node.

Returns

The new target position.

	)

Check if two lines intersect.

Parameters

a	Position a. (line 1)
b	Position b. (line 1)
v	Position c. (line 2)
d	Position d. (line 2)
axis	Axis that the second line being tested is on.

Returns

If the lines intersect.
