How do I match the player gravity with an entity gravity |
| 04:32 |
untilted |
I'm using set_acceleration |
| 04:33 |
MTDiscord |
<warr1024> smells like an xy problem, seeing how player movement happens client side while entity movement is authoritative server-side and prediction may be off |
| 04:34 |
MTDiscord |
<warr1024> if you want them to fall at the exact same rate together, you might have to do some kind of attachment |
| 04:34 |
untilted |
Oh I'm not doing a vehicle/boat, it's just a simple walking mob |
| 04:34 |
MTDiscord |
<warr1024> otherwise they'll likely drift out of sync just from step jank. |
| 04:35 |
MTDiscord |
<warr1024> I think player's gravity is like y=-10 or y=-9.81 or something earth-like |
| 04:35 |
untilted |
I'm doing -10 but it still feels very floaty |
| 04:35 |
untilted |
I think I'm just misunderstanding how the set_velocity and set_acceleration vectors should work together |
| 04:37 |
MTDiscord |
<warr1024> The way I understand it, you just set acceleration for gravity, and you don't have to set velocity |
| 04:37 |
MTDiscord |
<warr1024> acceleration modifies velocity (assuming the entity isn't already standing on a surface) |
| 04:37 |
MTDiscord |
<warr1024> like, continuously |
| 04:38 |
MTDiscord |
<warr1024> you might set velocity if you wanted it to jump, and then let the acceleration handle the ballistic arc after that |
| 04:39 |
untilted |
that sounds very nice |
| 04:40 |
untilted |
i did a parabolic knockback with just set_velocity vectors lol |
| 04:44 |
untilted |
Are player physics written in lua or in cpp? |
| 04:44 |
untilted |
I'm comparing the get_velocity vectors of my player and the entities |
| 04:44 |
MTDiscord |
<warr1024> All the entity physics I'm pretty sure is C++ engine-side, and involves a bunch of like network prediction and such so it wouldn't be too straightforward to do in Lua that only runs server-side. |
| 04:45 |
MTDiscord |
<warr1024> When you get the player's velocity, it'll be delayed, and I think it might even be inferred server-side based on player position updates, i.e. you don't actually know the real instantaneous velocity that the client knows |
| 04:45 |
MTDiscord |
<warr1024> this is why stuff like player falling damage calcs are done client-side. |
| 04:47 |
untilted |
I see, that's not a big problem because I can still tell from this print that the player reaches about -10y velocity just before landing from a 4 block height |

Ok I'm obviously doing something wrong using set_velocity to move my mobs |
| 05:19 |
untilted |
Are we supposed to just use set_acceleration now? |
| 05:20 |
untilted |
along with add_velocity? |
| 05:25 |
untilted |
i feel like using set_velocity is the wrong idea, im going to need documentation |

Yeah I can't use set_velocity on the same on_set callback and then expect set_acceleration to do its thing when im resetting the end velocity every call |
| 06:14 |
untilted |
I'm going to have fun tomorrow |
