Getting hostile mobs on horses to attack people

Title explains it all. I do currently use nms in my plugins.

 

@thebmanswan541 My suggestion is to use custom PathfinderGoals.

(Yepp, you have to set the target of the horse and the mounted entity)

But there might be other ways

 

@thebmanswan541
Not sure if a hostile mob could actually damage a player while on a horse, but you might be able to do it via a runnable. Just have the horse target the nearest player and have a runnable every 20seconds and check if the player is near the hostile on the horse, and if they are use Entity#damage to attack the player.

 

If you really want it to do that, you'll need this path finder goal: PathfinderGoalMoveTowardsTarget. At the same time, use the example above, from 97WaterPolo, and everything should work fine. If it doesn't work, reply with the error and we'll try to fix it.
