Hmm, lua_api.txt notes that Raycast:next() can be nil. What's the difference between nil and { type = "nothing" } ? |
| 17:51 |
Krock |
"nil" is when it reached the end |
| 17:51 |
ANAND |
Oh |
| 17:51 |
ANAND |
Then what does { type = "nothing" } signify? |
| 17:51 |
Krock |
never seen that being pushed to Lua |
| 17:52 |
ANAND |
o_O |

Krock |
push_pointed_thing c_content.cpp |
| 17:53 |
Lone_Wolf |
You got {type = "nothing"} from a raycast? |
| 17:53 |
ANAND |
I didn't |
| 17:53 |
Krock |
l_next() automatically returns nil if there's no pointed thing |
| 17:53 |
ANAND |
I got nil, while my mod checks for type == nothing |
| 17:53 |
Lone_Wolf |
Ah |
| 17:53 |
Krock |
== nothing is only needed for on_item_use, for example |
| 17:53 |
Lone_Wolf |
Yeah, you should just check for nil |
| 17:54 |
Krock |
raycast results other than the raycast API |
| 17:54 |
ANAND |
Ah |
| 17:54 |
Krock |
basically just pointed things |
| 17:54 |
ANAND |
Thought it applies to Raycast as well, thanks for clarifying. :) |

MinetestBot |
Another satisfied customer. Next! |
| 17:55 |
ANAND |
Never gets old, eh? :) |
| 17:55 |
Krock |
neither does this Raycast example. https://github.com/SmallJoker/farbows/blob/bb287199788f0615f3c81969f1943a3cd0089703/init.lua#L126-L128 |
| 17:57 |
ANAND |
Yeah, I remember you referring me to this mod once earlier. |
| 17:57 |
Krock |
:3 shameless self-advertising |
| 17:58 |
ANAND |
No it's helpful to have an example |
| 17:58 |
Krock |
though I didn't bother fixing a potential crash |

Krock: why don't you use a for loop? |
| 18:03 |
rubenwardy |
for thing in minetest.raycast(...) do |
| 18:03 |
rubenwardy |
it returns an iterable |
| 18:05 |
Krock |
was that added in the same commit? |
| 18:05 |
rubenwardy |
yeah, it's been there since the start |
| 18:05 |
Krock |
okay then .. til. |
| 18:06 |
rubenwardy |
documentation is here: https://github.com/minetest/minetest/blob/master/doc/lua_api.txt#L6339 |
| 18:06 |
Krock |
thanks rubenwardy |
| 18:07 |
rubenwardy |
I mean, you knew that, was just pointing out where the iterator part is documented |
| 18:07 |
rubenwardy |
easy to miss \o/ |

rubenwardy |
oh gosh, I'm such an idiot |
| 18:31 |
rubenwardy |
>closes a PR for being a duplicate of the issue it fixes |
| 18:31 |
Krock |
shall I confirm or deny? |
| 18:31 |
Krock |
I confirm |
| 18:54 |
Lone_Wolf |
Yeah I figured it'd be best to just do a new PR |
