Some help with movements

[runs]

I want a mob to move from pos to tpos. I do the following:

Code: Select all

local dir = vector.direction(pos, tpos)
local velocity = {
   x= self.max_speed* dir.x,
   y= self.max_speed* dir.y,
   z= self.max_speed* dir.z,
}
local new_yaw = minetest.dir_to_yaw(dir)
self.object:set_yaw(new_yaw)   
self.object:set_velocity(velocity)

But the mob moves in a straight movement.

Any help?

Yup, this code will move them in a straight line, given tpos is stationary.

What's the problem exactly, do they not go towards tpos, or you'd like them to arc towards tpos?

The second option I want. :-)

It's the easiest to use mobkit utils, for example:

Code: Select all

local tyaw = minetest.dir_to_yaw(vector.direction(pos, tpos))
mobkit.turn2yaw(self,tyaw,rate)          -- rate is in rads per sec
self.object:set_velocity(vector.multiply(minetest.yaw_to_dir(self.object:get_yaw()),max_speed)))

edit: or just try the new version, the code becomes:
mobkit.drive_to_pos(self,tpos,max_speed,?,?)

thanx!!! Just what I wanted! :-)
