Object 2 is a dummy object, it has a limb offset at the starting position you want the camera at. Every loop the camera is positioned at this limb's coordinates and pointed to object 1. Also, every limb the dummy object 2 is positioned at object 1's coordinates, now the camera will follow the user as they move.
Next we use the basic mouse looking code used in a lot of FPSs nowadays on DBP, and alter it a bit. We only rotate object 1 on the y axis and not the x axis so the user can't fly around, and then we rotate object 2 on yhe y and x axis so the user can look in all directions as the mouse moves.
Finally, we offset the limb from object 2 on the z axis by OFFSET#, OFFSET# changes depending on MOUSEMOVEZ(), so as the user scrolls the limb offsets closer and further away from the object, causing the camera to go with it, giving a zooming ability. There's limits invluced aswell, if OFFSET is less than -500 then it stops zooming out, and if it's greater than -100 then it stops zooming in. Alter the limits and the amountt he camera zooms in, aswell as what axis are changed for different effects. It might be a good idea to alter the Y offset of the limb aswell.
Controls:
- WSAD movement
- Move Mouse to look around
- Use scroll button to zoom in/out
Hope it helps, goodluck.
