(see source provided)
using the arrow keys repositions the camera from the defult position
this change is instantanious, having the camera appear in the new location.
does anyone know how i can have the camera slowly move and rotate from its old position to the new position.
changing the "jump" to a "move to" function

any help whould be appreciated

I believe there is such code available in the online Code Database. It's based on the idea that a set of values gradually approach their destination values. Just search "smooth" in the database and you should be able to find it.

do

set camera to follow cameraid,targetx,targety,targetz,yrotation,followdistance,yoffset,smoothing,collisionflag

point camera cameraid,targetx,targety,targetz

loop

targetx,y,z is what you want to follow
yrotation spins the camera around the object
followdistance is how far back from the object you are
yoffset lifts the camera up or down
smoothing is from 100 (maximum) to 1 (little)
and a collision flag of 1 will prevent the camera from moving if it hits a collision object.

if you don't point the camera, the camera will look flat acrross the xz plane.

ssj3_shadow: alternativly, you can mess with newtons fisics sdk, and aplly forces to objects and camera, thus eliminating the "repositioning" your talking about.

i already have the camera set up to change positions eg. the standard camera is 3rd person, and pressing the uparrow changes to first person, is ther a way to make this transition a smooth change ie in this example have the camera slowly zoom in untill it was in first person mode. does any one know how th alter the code provided to acheive this smooth transition from one camera position to another?

Yes, look into the curvevalue command - don't know it off by heart.

I use that in my games all the time, the command was designed for things like this.

CurveValue and also Curveangle are what you need. You tell it where you are, where you want to be, and how quickly you want to get there.

The Assets and Templates Tutorial in issue 29 uses curveAngle for the camera, combined with set camera to follow

why make things so complicated. all you have to do is change the followdistance and yoffset values to zero, adjust your camera minimum range to remove clipping with your playerobject, and set the point camera coordinates towards a vector in front of the player. A smoothing value of about 25-50 should make a nice smooth and quick change.

if you want to have some kind of accelleration or deccelleration to how fast the camera repositions... just decrement the smoothing value over time, and the camera will move faster and faster.

ok i've updated the code, it works fairly well, could any one help make it work 100%
i have adopted teh suggestion of Pheonixx (thanks), this works for to my liking for all camera angles except for the shoulder camera sub, when run the camera still appears at the shoulder, but slowly returns to where it was, this is ok but i need the camera to slowly move to the new location as well as slowly move back into its origional position, also as you will see as it runs, the sholder camera is in the wrong position untill you move the character this is a side effect of using Pheonixx suggestion.

any help making both transitions into sholder cam smooth not just the return move, and any ideas why the camera is in the wrong position untill i move the model
(see stand alone source provided)
