extenging a pole

[Master chief]

ok im making a gun with a extendable barrel in the top down view the barrel is facing north , i now that there is some sort or constrant usable but i dont know which to try

[johnl3d]

Not sure what your question is do you want the gun to point at something particular ? Need More iinput!

[Master chief]

ok if your every played any sci phi shootied your bould to find a deploy able gun , and that usualy mean that the barrel extends to a useable position i need to know what restrant will only allow the bone to move forward and back but not rotate or side to side.

 

also what would make it so a object when looked down apone only rotate but not tip

the barrel is facing north

 

I'm curious.

Why is the barrel facing north?

[itsjustme]

Make a bone for the base of the barrel and a bone for the part that extends. Then, in a Pose, put a translate limit on the bone for the extension with everything set to "0" except for the "Maximum Z"...make that the length of the base. That should make it where the extension can slide only from the base of the barrel to the end of the base of the barrel.

 

Hope that helps.
