New project need HELP

[minawageh]

i'm working on big project i need help in a lot of things
first i need to move parts with mouse and assemble them to each other so i tried to make snap function like in 3d's programs but i can't get it so
can any one help me how to get 2 objects aligned when they r close

You could keep track of both objects' positions. Once they are in a certain range of eachother set one to be the parent of the other and set the child's position so it has the correct offset to appear aligned. Then when you move the parent object the child will move with it.

If you want to move your object with the mouse along just the x-axis you could either translate mouse movement into object movement with something like this

#Disable mouse navigation
viz.mouse(viz.OFF)

ball = viz.add('ball.wrl')

def mymouse(e):
    #Move the object based on the mouse position
    ball.setPosition((e.x-0.5)*6,2,8)

viz.callback(viz.MOUSE_MOVE_EVENT, mymouse)

or you could move the object with the mouse buttons

#Disable mouse navigation
viz.mouse(viz.OFF)

ball = viz.add('ball.wrl', pos = [0,2,8])

#use buttons to control ball
vizact.whilemousedown(viz.MOUSEBUTTON_LEFT, ball.translate,vizact.elapsed(-1),0,0,viz.REL_PARENT)
vizact.whilemousedown(viz.MOUSEBUTTON_RIGHT, ball.translate,vizact.elapsed(1),0,0,viz.REL_PARENT)
