Feel free to test #9923. There should be a demo mod somewhere in the conversation to check whether all callbacks are run. |

I did not excessively test the callbacks but whether swaps are performed in the right conditions and that script-returned values are respected. |
| 10:33 |
Krock |
so indirectly also tested callbacks because without those it would not work properly |

pyrollo: do you think it's convenient to have auto-rotation around an arbitrary axis? |
| 13:36 |
pyrollo |
You mean for entities ? |
| 13:36 |
pgimeno |
yes |
| 13:36 |
pyrollo |
Yes, actually I had a use case. |
| 13:37 |
pyrollo |
I wanted to throw many blocs in the air with random rotation. |
| 13:37 |
pyrollo |
There is a way to do it on Lua side but it may saturate network exchanges with many packets |
| 13:38 |
pyrollo |
Started to do something, but I have a periodic rotation pos reset I dont know where |
| 13:38 |
pgimeno |
well it's doable but it's calculation intensive |
| 13:38 |
pyrollo |
Precision: my use case was for Kidscode |
| 13:39 |
pgimeno |
can't you do that with animations? |
| 13:39 |
pyrollo |
Why should it be intensive ? It's like automatic rotation but along two other angles |
| 13:39 |
pgimeno |
because automatic_rotate uses one of the built-in Euler angles in Irrlicht |
| 13:40 |
pgimeno |
but you can't easily rotate around an arbitrary axis using Eulers, the easiest way is to convert to matrix form, then rotate, then convert to Eulers again |
| 13:41 |
pgimeno |
you could make a bunch of animations that rotate the blocks around several axes, and pick one animation at random |
| 13:42 |

The direction I started to go was doing the same thing as here : |
| 13:44 |
pyrollo |
https://github.com/minetest/minetest/blob/master/src/client/content_cao.cpp#L1144 |
| 13:44 |
pyrollo |
for X and Z |
| 13:45 |
pyrollo |
These are also Euler angle, shouldn't this be ok on perf pov? |
| 13:46 |
pgimeno |
yes but the result is not rotation around an arbitrary axis, it's rotation around three Euler angles |
| 13:46 |
pyrollo |
Ok, sorry,my answer was not right :) I dont want to rotate around arbitrary axis, just being able to rotate around tree angles is ok |
| 13:46 |

Visual effect has been tested using Lua, it's ok :) |
| 13:47 |
pgimeno |
it seems very usage-specific |
| 13:47 |
pyrollo |
It's difficult to figure out the difference :D |
| 13:52 |
pgimeno |
then maybe you could do with even fewer animations, if you do it with animations |
| 13:52 |
pyrollo |
Because of you I'm getting headake watching video about 3D euler angles :) |
| 13:52 |
pgimeno |
sorry :) |

The use case is, for example, "visually" (not acurately) simulate an explosion throwing blocks in every direction |
| 13:54 |
pyrollo |
Without rotation speed, they seem to be quite static |
| 13:54 |
pgimeno |
hence, animations! |
| 13:54 |
pyrollo |
Maybe Y rotation is suficent if Y axis can be oriented |
| 13:54 |
pyrollo |
Yes but with animations, I may have to redefine a lot of things ? |
| 13:55 |
pyrollo |
For that, I'm using simple entities with corresponding node textures. |
| 13:56 |
pgimeno |
you can use set_rotation to place the cubes in an arbitrary rotation |
| 13:57 |
pyrollo |
I did it, but it does not look natural to have cubes keeping their angle. I'll try with a single rotation |
| 13:57 |
pgimeno |
that's how you could make the propeller of a plane, for example - you create the model so that the axis of the blade is vertical, and rotate it when it's attached to the plane so that it rotates in the direction of the plane |
| 13:57 |

If I understand coreclty Euler angles, I can rotate on arbitrary angle, if I rotate around the third angle, the two first angles defines my rotation angle |
| 13:59 |
pyrollo |
The thing is, I guess Y is the first one. I have to test it |
| 13:59 |
pyrollo |
*rotation axis, not angle |
| 14:01 |
pgimeno |
applying several rotations on different axes continuously (as you can easily do with Euler angles) is not equivalent to rotating around a certain axis. The rotating axis keeps varying. |
| 14:03 |
pyrollo |
Sorry, I gtg. Thanks for these geometric elements, I was not aware of that. I'll try some stuff tomorrow an try to show you if any interesting result comes from |

!tell pyrollo animated cube (untested): http://www.formauri.es/personal/pgimeno/temp/cuberot_anim.b3d - the animation has 49 frames but the first and last are equal, so use only the first 48 to loop properly |

Should I center the text with the middle of the screen or is that too likely to break something? https://i.imgur.com/FAchsPV.png |
| 16:09 |
Krock |
breaks shooter |
| 16:09 |
Krock |
well it would be distracting there |
| 16:10 |
Lone_Wolf |
Should I just shove the infotext in the top-right then? |
| 16:10 |
rubenwardy |
what's wrong where it is? |
| 16:10 |
Krock |
why does this need to be changed? |
| 16:11 |
Lone_Wolf |
Because it conflicts with the chat for me |
| 16:11 |

I can see a new HUD API which has all the default elements as elements, and they can be changed |

Welp, got that working. Guess I'll do a few more tests and start the PR |
