Frustum intersection query.

---

Spec:

intersect_frustum(
	double x1,
	double y1,
	double z1,
	double x2,
	double y2,
	double z2,
	long fov,
	bool players,
	bool npcs,
	bool display)

Parameters

• x1: The x component of the world position at the center of the frustum near plane
• y1: The y component of the world position at the center of the frustum near plane
• z1: The z component of the world position at the center of the frustum near plane
• x2: The x component of the world position at the center of the frustum far plane
• y2: The y component of the world position at the center of the frustum far plane
• z2: The z component of the world position at the center of the frustum far plane
• fov: The field of view of the frustum specified in degrees. If omitted, the default is 60
• players: true = test for players, false = do not test for players. If omitted, the default is true
• npcs: true = test for NPCs, false = do not test for NPCs. If omitted, the default is true
• display: true = display an outline showing the frustum of the test. If omitted, the default is false

Returns

• bool: True if there is at least one players/NPC positioned within the frustum

---

The context target is set as the closest actor inside the frustum

Example

local dir = vector3(get_view_dir())
local near = vector3(get_eye_pos()) + (dir * 0.2)
local far = near + (dir * 50)
if intersect_frustum(near.x,near.y,near.z,far.x,far.y,far.z,60)
then
set_context("target")
add_health_effect(-10)
end
