hi

I have finally got the time to get really stuck into my game which i have finally decided on being a 3rd person (this was decided after a lot of umming and ahhring over fps &tps).

The type of camera i would like to use is like this.

The camera itself stays in one position eg in the top corner of a room and rotates and pitches to follow the player.

Every time the player goes a certain distance from the camera, the camera gets repositioned so the player can see themself better.

Remember it is a static camera that turns and pitches

The exact camera type I want to use is the one they use in Metal gear solid (for any who are familiar)

I can probably do the detection of how far away the player is and i can reposition the camera but i dont know how to let the camera know where to position itself so that it can see the player.

Will i have to make several cameras or can it all be done with one camera?

Cheers

you could position the camera yourself in each room & write down its xyz#s then position the camera there when your player goes in that room.

There is that option but that would mean a hundred or so lines of



And there must be a way around that

Cheers anyway

You will already have fixed positions for the cameras. So, you need to establish which camera is closest, then if that camera can actually 'see' your player. If not use the second closest ... etc.

To establish which camera is nearest. Use a 3D distance function, there are plenty to be found ... just use the search button.

To establish if the camera can 'see' your player. Use the INTERSECT OBJECT command.

To have the camera look at your player use:
POINT CAMERA camera number , OBJECT POSITION X(player) , OBJECT POSITION Y(player) , OBJECT POSITION Z(player)

Thanks scraggle I will have a look for those functions and when using an intersect command will I have to attach a limb to the camera position?

Cheers

No, no limbs needed. The syntax is:
Return Float=INTERSECT OBJECT(Object Number, X, Y, Z, ToX, ToY, ToZ)

The Return Float Will return the distance from your camera (X,Y,Z) to your Player (ToX,ToY,ToZ) or return Zero if it doesn't intersect. Effectively combining steps 1 + 2 of my previous post.
