[color=red]the problem is
when i call class player
Player(pos =(20,30,0))
it show in output that dummy’s position is color=red

but when i right click
it show in output that dummy’s position is [color=red](-0.476363, -0.714544, 0.068275)

why it’s not a same point?
any idea?
it make me cry
:cry: b’cos i’m can’t fix it
help me please

Code without indention is not really readable, so here comes just generic advice:

You code changes the position of self.dummy in several places, for example Move.stepplayer (a task!). Obviously one of these lines changes the position of self.dummy BEFORE you can click the mouse for the first time.

A dummy way to debug would be to place “print” commands before all lines of code which change the position of self.dummy (search for “setPos” etc.), and then observe what happens.

thank you for your advice

i will try it :angry:

some one help this dude i cant figure it out either, never used actors and i dont have the girl model.

:smiley: yes i can fix it now

the problem is in task stepplayer

i should init self.point = self.dummy.getPos()
but i init self.point = Point3.zero()

thx for your advice :laughing:
it was a little problem 555
