Camera look around object

[Slastraf]

I want to make a camera with that you can watch an object from every angle.

The object itself shouldnt be moved or anthing.

 

How would you do this ?

I have found a gif that does just that.

It's been a while since I studied this, but that's how I remember it is:

x += R * sin(T) * cos(F)

y += R * sin(T) * sin(F)

z += R * cos(T)

T is on 0y rotation, F is on 0z rotation.

Are you looking for the player to rotate this or doing it on your own? This is basically 3rd person camera control with no limitations on it. If you place the camera at the same position as the object it's rotating around, then rotate the camera in whatever direction (x and y usually), then Move() the camera backwards (Move() in LE is relative to the entities rotation so a negative value in the z parameter would move it backwards) then you could get this same effect. It's what a lot of people here do for 3rd person camera functionality. No need for much math at all on your end. Note that you are doing this all in the same frame and you'd keep the rotation value between frames of the camera and just add/sub the value.

 

If you're looking for a nice smooth rotation that the player isn't doing, then look into the lua tween library below, and it gives you that. You'd use it to tween the rotation values over time.
