rayHit(start, end)
Launch a ray and returns the result of the test, the intersection point or nil and optionally the object. Note that only detects objects with physics collision enabled.
-
start: ray start -
end: ray end
point, object = rayHit(start, end)
Or.
point = rayHit(start, end, object)
Example 1: Test the intersection with the full scene.
function onSceneUpdate()
start = {0, 0, 0}
end = {100, 0, 0}
point, object = rayHit(start, end)
if point then
print(point) -- print point
print(getName(object)) -- print object name
end
end
Example 2: Test the intersection with an object.
object = getObject("object")
function onSceneUpdate()
start = {0, 0, 0}
end = {100, 0, 0}
point = rayHit(start, end, object)
if point then
print(point)
end
end
