Need help with Camera view above a moving object please.... Thanks so much

[kiki Chaika]

Greetings! Greetings! I would like to ask if there is a way when someone click on and object, it will allow the user to view as the object's perspective (or better yet, cam just above and behind it); the avatar has the option to "view as the moving object"? please? In other words, when you click on an object, a moving object in this case, a menu pops up which allow the user to view from the perspective of the moving object please? Any help will be great please... I really do not know much about scripting; if you can kindly please post the code on how to do this, it will be of great help. Thank you very much in advance kiki

This isn't the forum to ask for a script to be written for you, but we can help with scripts you may be having trouble with.

Here is a thread that may be of help to you though

thank you Ruth.

 

I actually tied to anaylze that thread you have given before I post this here...  but that script is viewing the obejct from the avatar's pespective.  while I would like to see if the script can be adjusted so that the camera is above the moving object instead.  I have studied and researched over 10 hr on this with no results, that is why I asked.  thanks.

Camera focus offset I believe is where you would adjust it. Otherwise, from your original explanation, I think it's basically what you're looking for. I'm at work in RL, so replying on my phone. Not able to go in world to modify the script for an example

thank you very much in advance for your help, whenever you are free.  much appreciated! ^.^

Now that I'm home and read through that other thread more clearly, I see that what you meant about the avatar's perspective. I'm working on something now that will put the camera in place of the object being followed

thank you very much in advance....

 

The object will be a moving object.... and if the cam view is like above and behind it....  "third" person view...

It will be perfect since it will allow the user to control the moving object, while seeing what the object "sees"

 

Thanks so much!!!!!

Here is what I have put together.

The first one will put your camera 1 meter in front of the object being followed. I didn't like the results of having it following behind, as it made the object look jittery, maybe someone else can fine tune that? I rarely work with cameras, and it's usually a stationary setting when someone sits on an object. I placed it into a HUD object so that it can be clicked on while following the object.

The second script is the test script I put into the object being followed. It communicates using llRegionSayTo when someone clicks it. If the person clicking it is wearing the hud object, the hud object will ask if they would like to follow the object they clicked

integer onoff;//toggle to determine whether or not to show the the dialog when touched. won't show if it is in idle stateinteger comchan = -991119;//this channel is for communication between the object being followed and the hud device, make sure they use the same channelinteger avchan;integer GotCam;//toggle to determine if the script has permissions to control camerainteger handler;key object;//the uuid of the object being followedsetcamera(vector pos, rotation rot)//set the camera params based on the object's position and rotation{    llSetCameraParams([        CAMERA_ACTIVE, 1, // 1 is active, 0 is inactive        CAMERA_FOCUS, pos+(<10.0,0.0,0.0>*rot),//focus 10 meters in front of the object        CAMERA_FOCUS_LOCKED,TRUE,        CAMERA_POSITION, pos+(<1.0,0.0,0.0>*rot),//place the camera 1 meter in front of the object-adjust as desired-<-1.0,0.0,1.0> will be 1 meter behind, and above the object        CAMERA_POSITION_LAG,0.0,        CAMERA_POSITION_LOCKED, TRUE // (TRUE or FALSE)    ]);}getcam(key id){    llRequestPermissions(id,PERMISSION_CONTROL_CAMERA);}avlisten()//this is the listener the dialog will communicate to{    llListenRemove(handler);    avchan = (integer)llFrand(-2000)-2000;    handler = llListen(avchan,"",llGetOwner(),"");}default{    state_entry()    {        llListen(comchan,"","","Here");//listens for the word "Here" from the object being followed.
