Finish condition: If the time runs out (if set with `max_timer`), otherwise does not finish
on its own.
### `rp_mobs.microtasks.walk_straight(walk_speed, yaw, jump, max_timer)`
### `rp_mobs.microtasks.walk_straight(walk_speed, yaw, jump, jump_clear_height, stop_at_object_collision, max_timer)`
Walk in a straight line, jumping if hitting obstacle and `jump~=nil`.
Walk in a straight horizontal line (on the XZ plane), will jump if hitting a node obstacle and `jump~=nil`.
It's recommended the mob is subject to gravity.
Parameters:
* `walk_speed`: How fast to walk
* `yaw`: walk direction in radians
* `jump`: jump strength if mob needs to jump or nil if no jumping
* `jump_clear_height`: how many nodes to jump up at most
* `stop_at_object_collision`: stop walking if colliding with object
* `max_timer`: automatically finish microtask after this many seconds (nil = infinite)
Finish condition: If the time runs out (if set with `max_timer`), otherwise does not finish
on its own.
Finish condition: If the time runs out (if set with `max_timer`) or collides with
and object if `stop_at_object_collision` is true.
### `rp_mobs.microtasks.walk_straight_towards(walk_speed, target_type, target, set_yaw, reach_distance, jump, max_timer)`
### `rp_mobs.microtasks.walk_straight_towards(walk_speed, target_type, target, set_yaw, reach_distance, jump, jump_clear_height, stop_at_reached, stop_at_object_collision, max_timer)`
Walk in a straight line towards a position or object.
Walk in a straight horizontal line (on the XZ plane) towards a position or object,
will jump if hitting node obstacle and `jump~=nil`.
It's recommended the mob is subject to gravity.
Parameters:
* `walk_speed`: walk speed
* `walk_speed`: How fast to walk
* `target_type`: "pos" (position) or "object"
* `target`: target, depending on `target_type`: position or object handle
* `set_yaw`: If true, will set mob's yaw to face target
* `reach_distance`: If mob is within this distance towards target, finish task
* `reach_distance`: If mob is within this distance towards target, stop walking. If `nil`, has no effect
* `jump`: jump strength if mob needs to jump or nil if no jumping
* `jump_clear_height`: how many nodes to jump up at most
* `stop_at_reached`: stop walking and finish if within `reach_distance` of target
* `stop_at_object_collision`: stop walking and finish if colliding with object
* `max_timer`: automatically finish microtask after this many seconds (nil = infinite)
Finish condition: If the target is within `reach_distance` of the mob. Otherwise, when
the time runs out (if `max_timer` was set)
Finish condition: If any of the following is true:
* When the time runs out (if `max_timer` was set)
* Target is within `reach_distance` of the mob and `stop_at_reached` is true
* When colliding with object if `stop_at_object_collision` is true
### `rp_mobs.microtasks.set_yaw(yaw)`
