- playerState : instance of the PlayerState class
- world : interface with a function
getBlock(position)returning the prismarine-block at the given position
A player state is an object containing the properties:
Read / Write properties:
- pos : position (vec3) of the player entity
- vel : velocity (vec3) of the player entity
- onGround : (boolean) is the player touching ground ?
- isInWater : (boolean) is the player in water ?
- isInLava : (boolean) is the player in lava ?
- isInWeb : (boolean) is the player in a web ?
- isCollidedHorizontally : (boolean) is the player collided horizontally with a solid block ?
- isCollidedVertically : (boolean) is the player collided vertically with a solid block ?
- elytraFlying : (boolean) is the player elytra flying ?
- jumpTicks : (integer) number of ticks before the player can auto-jump again
- jumpQueued : (boolean) true if the jump control state was true between the last tick and the current one
- fireworkRocketDuration : (number) how many ticks of firework boost are remaining ?
Read only properties:
- yaw : (float) the yaw angle, in radians, of the player entity
- pitch: (float) the pitch angle, in radians, of the player entity
- control : (object) control states vector with properties:
- forward
- back
- left
- right
- jump
- sprint
- sneak
