<MisterE> is it possible for a mod to get a stack traceback? Say I have an error that I know occurs, and it is caused by misuse of an api function, and I want to prevent a hard crash, but still give whoever is misusing the api function a log to help them fix the issue. Is there some function that will return the current stack traceback as a text string? |

<MisterE> does find_node_near work with fractional distances? Say i want to find air within 0.7 nodes from a position to check if a player should fall for blockbomber |
| 03:01 |
Yad |
Is a node timer considered part of the metadata system? |

What I can say is that the metadata system sure works beautifully in Minetest. :D |
| 03:48 |
Yad |
I can display information via the chat system, but I'm still learning how to put it to visual use though. |
| 03:48 |
Yad |
I was thinking of using animations but those are part of the node definition not the metadata. |
| 03:53 |
MTDiscord |
<MisterE> nodes dont have animations, except animated textures. You can build a 3d animation out of a special model and partially transparent animated textures, like the default torch does |
| 03:54 |
MTDiscord |
<GreenXenith> the default torch doesnt use that trick at all |
| 03:54 |
MTDiscord |
<MisterE> but yes its in the node definiton. If you want to use metadata for visual effects, you will have to pair the node with an entity |
| 03:54 |
MTDiscord |
<MisterE> Its flame wavers |
| 03:54 |
MTDiscord |
<MisterE> in 3d |
| 03:54 |
MTDiscord |
<GreenXenith> thats just a regular animated texture |
| 03:54 |
MTDiscord |
<GreenXenith> put on 4 planes |
| 03:54 |
MTDiscord |
<MisterE> ok, well its a builtin special model |
| 03:55 |
MTDiscord |
<GreenXenith> its not that special? |
| 03:55 |
MTDiscord |
<MisterE> ok ? |
| 03:55 |
MTDiscord |
<GreenXenith> it doesnt even combine the models into one, theres 3 torch models |
| 03:55 |
MTDiscord |
<MisterE> but not for the animation, thats for the wallmounted and ceiling and floor variations |
| 03:56 |
MTDiscord |
<GreenXenith> I know, im just reiterating that its not fancy |
| 03:56 |
MTDiscord |
<GreenXenith> its a regular model with regular texture animations |
| 03:56 |
MTDiscord |
<GreenXenith> the 3d node animation trick consists of having every animation state in the model and swapping to each frame using animated textures |
| 03:56 |
MTDiscord |
<MisterE> I hereby officially concede your point @GreenXenith |
| 03:56 |
MTDiscord |
<MisterE> ? |
| 03:57 |
MTDiscord |
<GreenXenith> ironically the 3d animation trick is pretty much what obj does for animations (which is awful) |
| 03:57 |
MTDiscord |
<MisterE> .obj? it supports animations? |
| 03:58 |
MTDiscord |
<GreenXenith> not technically |
| 03:58 |
MTDiscord |
<GreenXenith> its not part of the specification |
| 03:58 |
MTDiscord |
<GreenXenith> but last I checked, Blender supported exporting animations with obj |
| 03:59 |
MTDiscord |
<MisterE> interesting |

Thank you for going into detail on that. So besides replacing (and/or overlaying) a node with an entity, to visually represent metadata would I have to replace the node with another node? |
| 05:22 |
Yad |
For example, if I want a wall block to take damage and track that damage, before being removed at 100 damage points... |
| 05:23 |
Yad |
...perhaps I should register ten nodes, one for each 10-point increment, with a different texture for each... |
| 05:24 |
Yad |
...then track damage using an integer in metadata, and when for example it goes from 9 to 10, I replace the first node type with the second node type, and so on, passing the metadata along each time? |

Is making a node "digable" currently the only way to interact with it on a continuous mouse-press basis? |

I've thought about using a particle emitter attached to the player. |

<GreenXenith> I dont think a node needs to be diggable for on_punch to trigger repeatedly |
| 10:02 |
|
illwieckz joined #minetest |
| 10:08 |
Yad |
Well that's technically true I agree, because I can call punch_node as often as I like. :D |
| 10:09 |
Yad |
The trick was to use register_on_joinplayer and then spawn an entity which listens to get_player_control().LMB in its on_step event |
| 10:17 |
Yad |
Now I just need to combine that with get_pointed_thing_position |

<Benrob0329> Alright, what do you need PT for? |

Yad |
I need to know what the player is pointing at. |
| 18:10 |
MTDiscord |
<Benrob0329> Some callbacks return it, but otherwise you'll have to Raycast() |
| 18:10 |
Yad |
And then get its NodeRef so I can have an entity's on_step event interact with that node. |

So basically fire a probe out of the player's hand, as it were, to see what it hits? |
| 18:11 |
MTDiscord |
<Benrob0329> Probably the camera, but yeah thats the idea |
| 18:11 |
Yad |
That's a more technically accurate way of putting it, thank you. |
| 18:12 |
Yad |
Because the player is essentially just a point in space; the location of the camera. |

Then things like arms are attached to the player. |

Benrob0329: Thank you, but my main question reading up on it now in `lua_api.txt` is...how do I get pos2 for launching the ray? I suppose I could pick an arbitrary number of meters for length, and apply trigonometry to the camera angle? |
| 18:14 |
Yad |
`minetest.raycast(pos1, pos2, objects, liquids)` |

Benrob0329: At last that game actually helped me! <3 |
| 18:16 |
MTDiscord |
<GreenXenith> Yes, take the camera vector and set it to the length of the wielded item range |
| 18:16 |
MTDiscord |
<Benrob0329> Hah, at least it's good for something :P |
| 18:16 |
Yad |
heheheh yep |
| 18:17 |
Yad |
If you play Dokimi's Exile (now managed by Mantar), you'll notice how aspects of the endgame, as it were, remind me of your Infinite IKEA scenario. ^_~ |
| 18:17 |
Yad |
Benrob0329: I see what you're saying, I don't have to do the trigonometry manually, when I can simply multiply look_dir by the desired ray distance, and that to the player position. So simple it's brilliant! |

<Benrob0329> I've just realized that there might be a way to break the flashlight in IKEA, if you shut down the server with it on it should leave the light node in place, which won't get removed automatically |
| 18:21 |
MTDiscord |
<Benrob0329> But you should just be able to wave the flashlight through it and get rid of it |
| 18:22 |
MTDiscord |
<Benrob0329> I could always add an LBM to clean those up I suppose |
| 18:22 |
MTDiscord |
<Jonathon> or just make the light nodes have a node timer |
| 18:23 |
MTDiscord |
<Benrob0329> Well yes, but then you're starting 10 timers a second |
| 18:24 |
MTDiscord |
<Benrob0329> And those do continue to count if the node is swapped afaik |
| 18:24 |
MTDiscord |
<Jonathon> hmm, yeah |
| 18:25 |
MTDiscord |
<Jonathon> at the end of the day using nodes for light sources is just a hack given that entities cant propagate light (which is hard to implemenet) |
| 18:26 |
MTDiscord |
<Benrob0329> This isn't a serious issue, just a small graphical one. The light nodes are buildable_to and everyone has a flashlight |

<Warr1024> @Luatic what that filter does is essentially a nearest-up-linear-down filter, which prevents weird stairstep effects on non-integer scaling, but yes, it does create interpolated pixels at that point. |
| 19:05 |
MTDiscord |
<Warr1024> It may also be noteworthy that there's a bug in 9-patch buttons in formspecs when that's turned on. Seems 9-patch must never have been tested with GUI scaling enabled... |

I estimate just about everything is not tested with gui scaling on |

<Warr1024> That's probably one of the biggest reasons it's not enabled by default. |
