Solved Adding acceleration/deceleration to a horse.

Essentially what I am trying to do is add smooth acceleration/deceleration to a horse to use it as the main moving part for a spaceship plugin. I tried a lot of stupid things that most definitely didn't work and I realised that modifying velocity of a horse that is moving yields really unpredictable behaviour where the velocity you set and the velocity the game is setting from the movement kind of fight against eachother. Anyone have a simple way of doing this? Thanks.

 

There is no smooth way of doing this because of the way movement works.
Server-side movement will be bumpy from your perspective due to latency and such. Movement is entirely handled by the client; the server generally only verifies. It is like this with all games.

Smooth server-side movement is not achievable.

 

I think I may have mis-worded this a little.. it's not like.. jittery, its like lets say I was setting Velocity to 10 0 0 when you are moving in the +x direction you go really fast and when you are moving in the -x direction you barely move, as if it was adding instead of setting.

 

Then you have to figure out the way velocity works.

 

Is this like you telling me that I don't get how to fix it or you telling me there is no way of fixing it

 

The first one probably but i can't say for sure.
Sounds to me like if 10 0 0 moves you fast towards +x but slowly towards -x, the first digit is the x movement. Logically -10 would move you fast towards -x.
I could be wrong.

 

yes but the thing is setting it to 0 does not freeze you and setting it to - the velocity of the horse also does not so its just really dumb.

 

@Symphonic use the launchprojectile method for movement, and use the space bar for acceleration and deceleration(increase the velocity of the vector) as horses have a jump bar

 

Don't think I can track that as the horse jump bar is client sided.. The launchprojectile might work but now comes the issue of getting input.. I've been stuck in a loop like this for a while figuring out how to get some input from the keyboard while also moving the entity the way I want...

 

@Symphonic Could you use this:https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/entity/HorseJumpEvent.html?

Or this:https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/AbstractHorse.html#getJumpStrength--?

 

#2 is constant and has nothing to do with when the player jumps

I could use #1 but i feel like that’s a terrible control scheme, I think im gonna go the route of trying to intercept movement/input packets and then modify the movement based on that. Thanks for the help though, I will definitely use the spacebar for some part of the controls and this might make it easier.
