backport and tweak internal functions and document it
* backported internal fucntions cos the narcisits tenplus1 dont property document the changes.. the commit 457eb1838cd1e694052298a42c84cd7b061d809d of main master upstream tag has bugs inside changes and undocumented changes too, this commit was named "code tweaks" only! * also backported commit ed74f3c4c4d3f4c7e17127fa26ac4f0adbd2900d named "add :is_inside() function (thx cora for idea)" non credited in changes * add global node_ok, effect and yaw_to_pos global deprecated functions for backguard compatibility * add selft mob_class list of functions also is_inside, yaw_to_pos, set_velocitymain

Internal Functions
|

------------------
|

|

Each mob contains a set of functions that can be called for use internally or from
|

another mod entirely, replace mob_class with the mob entity variable:
|
||||
|
||||
mob_class:mob_sound(sound) -- play sound at mob position
|
||||
mob_class:do_attack(player) -- if not already attacking, attack object given
|
||||
mob_class:stop_attack() -- stops mob attacking
|
||||
mob_class:collision() -- checks for player collision with mob and returns {x, z} vector
|
||||
mob_class:set_velocity(velocity) -- move at velocity in the facing direction
|
||||
mob_class:get_velocity() -- returns mob speed value
|
||||
mob_class:set_yaw(yaw, delay) -- change mob yaw, delay is for smooth rotation (default:0)
|
||||
mob_class:yaw_to_pos(pos, delay) -- rotates mod to look at position and returns new yaw
|
||||
mob_class:set_animation(animation, force) -- set mob animation
|
||||
mob_class:line_of_sight(pos1, pos2) -- internal line of sight function
|
||||
mob_class:attempt_flight_correction(override) -- check for stuck flying mobs and fix
|
||||
mob_class:update_tag(newname) -- update nametag or give new name
|
||||
mob_class:do_jump() -- check if mob can jump then jump
|
||||
mob_class:follow_holding(clicker) -- return True if mob likes what player is holding
|
||||
mob_class:day_docile() -- return True if mob docile during current daytime
|
||||
mob_class:mob_expire(pos, dtime) -- check if mob is to despawn
|
||||
mob_class:get_nodes() -- get specific nodes around mob
|
||||
mob_class:on_blast(damage) -- function called when mob in blast area
|
