How to limit flying camera zoom?

Is there a way to set a zoom range to a flying camera so that the user can’t zoom into objects and zoom out infinitely?

In fact it’s not zooming. When you use the mouse wheel or press W/S keys you do the same thing: you move the scene’s camera forward/backward. The same action but with different speed. Actually, the real zooming is used only with an orthographic camera. That’s the only case. In all other cases you change the scene’s camera position. That’s why the camera can fly through objects when zoomed in too close.

I want the player to be able to zoom in on certain objects too look at them more closely but, of course, not zoom in too far and go into them.

If you don’t use keys to move camera you can disable zooming this way

and then use this puzzle for zooming

Or you will need to write some script to change the scene’s camera actual zoom value with the mouse wheel.

Also the zooming steps are a bit to big (one scroll zooms too much), is there a way to control that?

You can tweek the mouse wheel “zooming” speed this way

The default value for the Flying camera is 75. Too fast. Set it to 15-30. 15 is the default value for the First Person camera. It’s an optimal value.

For example, with minZoom and maxZoom or something?

Custom controls via JS only. With puzzles you can’t control app.camera.zoom value.

But you can use constraints for the scene camera limiting its position.

For example, after tweening move the special empty object to the scene camera’s position and add a constraint to limit the distance from this object.
