Tank turret rotation, gun muzzle seat attachment thing problem

[darkstylerz]

Hello, I have learned a bit more about constructing stuff, but I got new problem.

There is the red box I want to use the axis of turret to determine it's location, being positioned always in front of the gun barrel. It's own axis will be used as a seat, and that is not a problem. I kinda want it to support camera, so I can have the view coming always from the gun barrel like here:

So you kinda sit on box, and it goes with you, always pointing through reticle no matter what. Avatar is no problem, since I wrote script that hides it. It will just be lovely if you actually seen through the gun instead of coupola.

I can write quite a lot of things, but those rotation relation things make my brain melt.

Please help.

Thank you!

It might be easier if you were in mouselook.  Then you could capture the camera's rotation with llGetCameraRot  and simply rotate the turret and gun to match.  Something like

grCameraRotation = llGetCameraRot();vector gvCarDirection = <1.0,0.0,0.0>*llGetRot();vector gvCameraDirection = <1.0,0.0,0.0>*grCameraRotation;rotation grTurretAxis = llRotBetween(gvCarDirection,gvCameraDirection);llSetLinkPrimitiveParamsFast (giTurretLink, [ PRIM_ROT_LOCAL,grTurretAxis]);
