Title: SentryGun Two Smooth Look at Axis
Post by: Kothe on April 24, 2014, 04:06:57 PM

Hi.
I´m trying to set to a compounded SentryGun. Im doing it with Smooth Look at.
The movement for the Y axis object works fine, but I need the X axis to the other object to follow "up and down" the character.
I have modeled it with all the posibles axis orientations, and setting diferents
up vectors.

  How can I achive it ?

Hello
So you can get the Y axis correctly.
The X axis...not yet.

Take this action, and check BlockY.
This will help. But not yet done.
The gun won´t rotate on Y axis because my action is blocking it.
I´m not yet able to make this correctly.
I´m currently trying to make a sentry gun movement too.
So if I can do something more I will post it.

Take a look.

Maybe I´m wrong , but with pen and paper seems to work.

Yes.
 This link.  https://hutonggames.fogbugz.com/default.asp?W971

 I have test it, it works when the character moves fordward and backward, the sentry aims the head .... but not when it moves Up and down..... :(  :S   

 What I missing ?

1-You will need to have quaternion actions. Get them here https://hutonggames.fogbugz.com/default.asp?W967 (https://hutonggames.fogbugz.com/default.asp?W967).
2-Import this custom package.


We need to use quaternions because they have more power than simple rotations.
"Basically" it´s this.
